How to turn on and off the sound on a Starline alarm system

The StarLine A93 car security system, as you know, has many functions that are available by default. Let's look at the key fob controls: there are 4 conditionally numbered buttons (from left to right). The key fob interface is controlled by short, long, sequential and simultaneous presses of a combination of buttons responsible for different commands.

To turn on the security mode, you need to briefly press the first button, to disable this mode, press the second button (shortly).
By pressing the third button (briefly), a survey of the vehicle’s condition is carried out, while the car’s battery voltage and the temperature inside the cabin are displayed on the LCD screen.
A double short press on the fourth button searches for a car in the parking lot, and the engine temperature is displayed on the screen.
When you press the first button (long) and then the second (short), it turns on the silent security mode. This mode is disabled by long pressing the second button, and then by short pressing it.
Long simultaneous pressing of the first and third buttons turns on the “Anti-robbery” or “Panic” mode, and an alarm is triggered to scare away intruders. You can turn off this mode by briefly pressing the second button.
The buttons are locked by briefly simultaneously pressing the second and fourth buttons, and in order to unlock the key fob, you need to briefly and simultaneously press the first and fourth buttons.
A short double press of the first button turns on or off the shock sensor of the first zone; when pressed again, the shock sensor of the second zone is checked. To exit this menu, you need to make a short double press on the first button again.
Double short press of the third button enables or disables the tilt/motion sensor.

Setting up a new Starline A93 alarm key fob

Another option for the popular car alarm available on the market today is Starline A93, A61, and A91. These models do not have the option to adjust the sound signal - the volume cannot be increased or decreased. But it is also not necessary to constantly listen to the car siren.

There is a silent arming mode - first, the first key is pressed for a long time, and after the key fob emits a signal, it is briefly pressed again. In this case, the car will be in security mode with a siren and will notify the owner of attempts to break into. You can completely turn off the sound - this is a silent security option. It turns on in a similar way - by long pressing the first button, and then short pressing the second.

Some owners encounter problems when the key fob does not make sound signals and automatically switches to vibration or silent mode. There are several reasons for this:

if the sound disappears, you can check the power supply of the remote control - often the battery, when the charge is weak, tends to conserve energy, so the sounds may disappear;
It is also recommended to check the limit switches on the doors and trunk of the car - if, according to the system, the car does not open or close the doors, the signal may not be played;
Sometimes the impact of the remote control displaces the metal plates inside the key fob. To restore functionality, you need to disassemble the remote control and put the plate back in the center;
you need to check the serviceability of the control wire - perhaps there is no signal;
recheck the cables going to the main control unit, ring the contacts;
Analyze the state of the shock and tilt sensor.

If everything is in order, then it is recommended to take the car for service and consult with professional installers.

Modern security systems have long ceased to be simply security systems that protect a car from theft. Now they have a lot of additional functions, including autostart, turbo timer, car search using GPS, communication with emergency services, etc. The owner can also program the sound on the Starline alarm key fob to turn off or turn on the sound.

Turning on the sound on the Starline alarm key fob is quite simple. The security system is lightweight and easy to control. To turn the sound signal on and off, you will need to perform a minimum of actions.

There are several ways to turn off the sound on Starline car alarms. In this case, it is necessary to take into account the system model.

On old security systems, the mode is turned off as follows. Initially press button 3 for a few seconds. After notification in the form of 1 long and 1 short signal, the cursor in the row of icons located at the bottom of the display begins to blink. Using short successive presses on key 3, you reach the required icon (crossed out speaker). Then press button 1. At the same time, the car gives a light warning, and a melody is played on the key fob. Silent mode is activated.

In modern alarm systems (Starline A93, A91, D94, etc.), switching to silent mode is easier. To do this, press button 1 for a long time until a melodic notification appears. Then, by pressing button 2, the switch to the silent security mode is confirmed. In this case, a corresponding icon in the form of a crossed out speaker will appear on the key fob screen.

The Starline A93 alarm system is a multifunctional system that performs a range of different tasks.

There are four buttons on the key fob, each of which is responsible for its own function.

A short press of the first key will arm the car. Removal is carried out by briefly holding the second button.
The third one sends a request about the condition of the car, and the LCD screen displays data about the battery charge reserve and the temperature inside the car.
Fourth – searching for a car in the parking lot. The Starline alarm will sound, and the key fob screen will display information about the engine temperature.
A long press of the first key, and then a short press of the second, turns on silent mode. The Starline alarm system will not sound, but the owner will receive notifications about hacking attempts. You can turn off this mode by long-pressing the second button, and then briefly clicking on it again.
When you hold down the first and third buttons, the “Panic” function is activated. Sound and light signals are triggered, scaring away potential intruders. It turns off by briefly holding the second key.
You can lock all buttons on the Starline key fob to prevent them from being pressed accidentally. You need to press the second and fourth together. Unlocking is done by simultaneously holding down the first to fourth key.
There is an additional option to disable or enable the shock sensor, which occurs when you press 1 button twice. First the sensor of the first zone is turned off, then the second. Once held again, it will activate.
You can turn off the tilt sensor by pressing key number three twice.

In addition, the Starline A93 alarm system has a lot of other functions. Among the main tasks of the device.

Security actions. The system turns off the ignition, locks the doors and hood lock. This prevents not only car theft, but also battery theft.
Automatic heating of the power plant. You can program the motor to turn on at certain hours and heat it up to operating temperature. Additionally, you can assign interior heating.
Setting up service options. The owner of a Starline car alarm can prescribe the time for oil changes, scheduled repairs, etc. During operation, the screen will show how much time is left before a particular procedure.
Turbo timer. A useful Starline option for owners of turbocharged cars. After a fast drive, some parts of the intake tract heat up to serious temperatures. Instant shutdown of the engine negatively affects the viability of the elements. The turbo timer forces the turbine to operate until the temperature drops to normal levels, which has a positive effect on its performance.

Sometimes the alarm starts to malfunction. If the reason is a deep discharge of the battery, then the battery should be replaced. However, there may be cases when the Starline car alarm will not work correctly even after installing a new part. Then you should reset to factory settings:

turn off the ignition;
press the settings button 9 times;
turn on the ignition, nine siren signals will indicate the success of the procedure;
Let's see a second reset for the second table, now you need to press the settings key ten times;
after finishing, click on the service button and listen to one siren signal;
press K1 of the key fob, the machine will make a sound, indicating a return to standard settings;
turn off the ignition, the car will blink three times with the emergency lights, indicating a successful procedure.

When purchasing a device, you will need to link it to the car. You need to know where the Valet service button is located. After that:

turn off the ignition, disarm the car, and then press the Valet key seven times;
turn on the ignition, the car will give seven light and sound signals, confirming entry into the binding mode;
press buttons 1 and 2 on the key fob;
the Starline machine and remote control will emit a signal;
When the ignition is turned off, the car will blink its headlights three times, confirming successful binding.

After this, this Starline keychain will be fully functional.

After various types of problems have arisen that require a complex emergency shutdown of the StarLine system, you need to bring your car’s security capabilities back to life. First of all, it is necessary to identify and eliminate the cause that caused the failure in the normal operation of the system. Ignoring this instruction may result in repeated system failure.

After eliminating the cause of the failure, we perform the following manipulations:

make sure there is no key in the ignition switch;
we ensure that all doors, hood and trunk are closed;
put the car on the parking brake;
Press the button on the key fob with the “locked lock” emblem.

The StarLine alarm is turned on and working properly if:

the LED indicator on the car flashed;
one beep sounded on the vehicle;
the car's dimensions blinked once;
all doors were closed via central locking;
one short signal sounded on the key fob;
“speaker” and “locked lock” icons appeared on the key fob screen.

Solutions

Now let’s take a closer look at what to do if the Starline A93 or A91 alarm siren does not work. We will pay special attention to the absence of a signal on the security system control key fob.

No siren sound

The most common situation is when the sound on the Starline alarm does not work. For example, you give an arming command, but you only see the side lights flashing and no response. A similar situation can occur when you try to break into a car, for example, when you hit the body (a hammer will appear on the screen) or when you try to open the doors on a car with the Starline alarm activated. To resolve the issue, try the following steps.

Make sure silent mode is turned off

Car owners often complain that the siren on the Starline A93 alarm system does not work. At the same time, they themselves activate the silent mode and forget about it. To activate the sound signal, press button 1 (long) until the melody appears, and then click again on the same button briefly until confirmation appears. After this, make sure that the Starline siren is working normally.

Check the mechanical part

In a situation where the Starline A61 siren does not work, check its serviceability. To do this, take the following steps:

Unplug the gray security wire where it connects to the red wire (the one that goes to the siren).
Apply +12 V from the battery to the red wire.
If the siren works, then the reason is different.
If there is no sound, connect the black wire to “minus” (ground), and from the battery to “plus”.

If, after the steps discussed above, the Starline A61 or other model alarm siren still does not work, dismantle it and connect it directly to the battery. If this does not work, it means the device is burnt out and requires replacement/repair. Alternatively, try replacing the B772 transistor, which is easy to find in radio parts stores. If there is no result, buy a new siren.

If the test shows that the Starline alarm siren is working properly, take the following steps:

Check the integrity of the vehicle wiring.
Change the control unit.
Make sure there is good mass.
Check the 10A fuses installed in the red wires.

The steps discussed above often help solve the problem if the sound of the Starline A93 siren disappears. Start by exploring the settings and checking the signal source itself. If diagnostics indicate more serious problems, proceed to repair/replacement.

No sound on key fob

The second situation that requires consideration is that the sound on the Starline alarm key fob has disappeared. At the same time, the security system itself often works. Below we will look at how to proceed to solve the problem.

Check your remote settings

In a situation where the sound on the Starline key fob does not work, start by checking the settings. The alarm remote may be set to silent mode. Take the following steps:

Enter the options programming menu by pressing button 4 until a long and two short beeps appear.

Select option F4 and press button 4 (long).

Select parameters by pressing keys 4 and 1, and set the value using keys 2 and 3 (short press). Set GROUND 1. At the same stage, you can select the Siren or Trill signal option, and then use buttons 2 and 3 to set the volume in the range from 1 to 9.

Replace the power supply

One of the reasons why the sound on the Starline key fob disappeared when arming was the discharge of the power supply. To test this version, try replacing the batteries in the remote control and check whether it works or not.

Setting the sensitivity of the Starline A93 shock sensor from the key fob

The Starline B9 and B92 models belong to the middle price segment. There are no options here - for example, it is impossible to turn off the sound of the key fob; it will always notify the owner of attempts to enter using sound signals.

At the same time, in the dark, the owner of the car has the opportunity to set a silent security mode. To do this, press the first button until the key fob beeps, and then quickly press the second button. Now the security without a siren signal is activated - when attempting to enter, it will not make noise, simulating a trill or bells, but will simply flash its dimensions. In this case, the owner will receive a corresponding notification on the remote control.

The security system has two zones where these elements are located. Correctly setting the shock sensors will prevent accidental alarm activation. To adjust the sensitivity level of Starline A93 you need.

Remove the car from security mode.
Long press the third key, and then perform another short click.
After this, the shock sensor setting of the first zone will be activated. You can adjust the level using the second (more) or third (less) key on the Starline remote control.
Having set the desired level, briefly click on key 3. Now the sensitivity settings for the shock sensor of the second area are available. The adjustment is carried out in the same way.

We turn off the security mode, and then press the fourth button for a long time. Next, briefly hold this key again.
After entering the adjustment mode, set the sensitivity using buttons two (more) and three (less).

The car alarm has a sound changing function. If desired, you can choose a quieter mode of operation of the Starline key fob itself or make the siren volume louder or quieter. To do this, you need to go to the settings menu by long pressing key number four (at least five seconds).

Then you have access to adjusting the signal volume - there is a silent mode. You can choose the system operation options: siren or trill.

turn on the ignition, then go to settings and scroll to the Soun section;
press button 3 for a long time, and then press it again briefly, the key fob will show the current volume value (default – 2);
use keys 2 or 3 to change the parameter in the range from 1 to 9;
We also exit the menu by long and short pressing key 3.

You can complete this task by following a simple procedure.

You need to enter the Starline settings mode by long pressing the fourth key on the key fob. After this, one melodic signal and two short ones will sound, and the clock values will begin to blink.
Use keys 2 or 3 to set the clock parameter up or down.
After finishing, press button 4, which will put the Starline key fob into minute setting mode. The display is carried out in a similar way.
Another press of the fourth button takes you to the alarm settings. The installation principle is carried out in the same way.
The programming mode exits automatically after 8 seconds.

The Starline B9 and B92 models belong to the middle price segment. There are no options here - for example, it is impossible to turn off the sound of the key fob; it will always notify the owner of attempts to enter using sound signals. However, in the dark, the owner of the car has the opportunity to set a silent security mode.

To do this, press the first button until the key fob beeps, and then quickly press the second button. Now the security without a siren signal is activated - when attempting to enter, it will not make noise, simulating a trill or bells, but will simply flash its dimensions. In this case, the owner will receive a corresponding notification on the remote control.

Turning off the sound on a Starline device is as easy as activating this option. For this, button 2 is intended (the middle of the buttons in the figure above). As with turning on, you need to perform some preliminary steps:

Put the car on the handbrake.
Close the hood, trunk and all doors to the vehicle interior tightly.
Use the cursor to find the icon on the screen as shown in the figure.
Press the middle button on the edge of the key fob.
Make sure that thumbnails of this type appear on the screen (after gaining experience, you don’t have to do this)

The alarm sound is now disabled. The car will respond to the described actions with single light and sound signals. The alarm LED should flash as normal. That's all the wisdom. As you can see, there is nothing particularly complicated in this procedure.

Why does the StarLine alarm sound not work?

The Starline A93, A96, and E90 models have a number of additional functions that make life easier for the owner. So, the owner of the car can not only activate the silent security mode - on the remote control you need to press key one for a long time, and then press the second button again briefly. In addition, the system provides an option for setting signal parameters.

To enter the sound function programming menu, you must hold down the fourth key. First, the key fob will emit one long beep, then two short beeps. A corresponding menu will appear on the screen with the ability to select the appropriate mode:

loud signals - RUDE;
quiet signals – WEAK;
vibration signal only – VIBR;
alarm system Siren - SIG1;
alarm system Trill - SIG2.

Switching between items is carried out by short pressing button four (forward) or key one (backward). The value is selected through a short click on keys two and three.

Disabling sound signals on Starline A91, A92 or A93 models occurs in the same way. According to the instructions, you need to press the first key for a long time, and then briefly press the second. After this, the car will go into silent security mode. In this case, an icon in the form of a crossed out speaker will be displayed on the display. The developers do not provide an option to turn off sound signals on the remote control itself.

To turn on the sound on the old generation Starline alarm system, use only a combination of buttons. In this case, the course menu is no longer used. To activate the siren, you must press button 2 for several seconds until the key fob emits an audible warning. Then you need to press the same key. The alarm now works in sound mode again.

To activate the siren in Starline security systems of modern models (car alarms A 91, A93, etc.), you need to press key 1 for several seconds until you receive an alert in the form of a melody. Then a single short press on the same button turns on the Starline alarm sound mode.

After performing these actions, the icon in the form of a crossed out speaker becomes inactive.

The Starline A93 alarm system has the option of customizable automatic engine start:

enter the programming menu by long pressing button 3, a signal should sound, and then click on the button again;
Use buttons 2 or 3 to select the required function;
key 1 helps you select the desired value; you can set the duration of the starter operation, engine warm-up and its time;
We return to the menu by pressing the third button for a long time, and then again briefly.

You can disable the Starline alarm on your car using the remote control or service button if the device for controlling the security system is faulty. To turn off the key fob, use a key with an indicator in the form of an open lock. To independently unlock the engine in emergency mode, an individual password can be used, the availability of which depends on the settings of the anti-theft complex.

Why is the Valet service button needed and where is it located?

One of the most effective ways to protect your car from attacks by intruders is to install a security system. Alarm systems from different manufacturers differ in functionality and the range of installed electronic systems. One such system is StarLine. For proper use, it is important to know all the nuances of operating the system and, of course, how to turn off the alarm on the car.

How to turn on the siren using a key fob

The first of the buttons on the edge of the key fob is used to turn on the audible security alarm. Before pressing it, you must make sure that the ignition is turned off and the hood, doors and trunk are closed. If you do not do this, you will not be able to turn on the siren. Instead of a normal reaction, the car will give out four light signals and four sound signals simultaneously. Having fulfilled the above requirements, you can safely press the first button (the one closest to the device’s antenna) - the result will be a single signal of dimensions and one sound. The door locks connected to the alarm will lock and access to the interior will be closed until the next command from the key fob. This is not all that will happen if you turn on the sound on the Starline alarm. You can make sure that everything is in order by looking at the LED alarm light - if it blinks, then everything is OK. The picture below shows the key fob itself and the sound button.

Also keep in mind that if you turn on the sound on the key fob, icons of all your actions will be displayed on the device screen.

How to increase the sound on a Starline alarm system

Some car alarm models Starline A91W, A94 or B9 allow you to increase the volume of the siren and adjust this parameter at your discretion. To set this parameter, you will need to enter programming mode.

With the ignition off, you need to click on the Valet service key 5 times. The button is usually located in the door pockets, between the front seats on the center tunnel, inside the glove box, near the steering column, near the pedal assembly or under the decorative cover of the front panel (next to the fuse box).

Then turn on the ignition and briefly press buttons two and three to select Soun, where you can add volume. To do this, press the third button for a long time (until a characteristic signal), and then again briefly. An indication of the current value appears on the key fob (factory setting is two). You can turn down the volume with keys one or two, and turn up the volume with button three. The maximum parameter is nine, the minimum is one. After turning off the ignition, the indicator will be saved.

Setting up ringtones

This function is included in the set of basic alarm functions Starline E90, E91 and F3. Configuration is carried out directly through the key fob. First, press the fourth key for a long time until the remote control emits a melodic signal, and then two more short beeps.

The selections now flash on the display. The owner, by short pressing the fourth button, selects item F4 (alarm volume and selection of melody for the communicator). The desired parameter is set using keys two or three (decrease and increase, respectively). Exiting the programming mode occurs automatically - just do not click anything for eight seconds.

4. How to register the Starline A91 key fob yourself

In total, the A91 can be programmed (bind, flash, register, write) four key fobs. It doesn't matter if they have an LCD display or not.

Please note that when programming new remote controls, the old ones are erased from memory. Therefore, the recording procedure must be performed immediately with all the key fobs you have on hand.

To register new key fobs, do the following.

click on Valet 7 times;
turn on the ignition - 7 siren signals will sound;
simultaneously press buttons 2 and 3 of the key fob with feedback or both buttons of the key fob without feedback and hold them until the siren signal is confirmed;
repeat step 3 for all existing remote controls: each successful programming of a subsequent key fob is confirmed by the corresponding number of siren signals;
turn off the ignition - the turns or lights will flash 5 times.

There should be no more than five seconds between points 1, 2 and 3. If it is more, then Starline will exit the key fob programming mode.

Arming without sound

When arming, the car always emits a sound signal, as well as when disarming this mode. But this is not very convenient in the dark, when silence is important. Therefore, you can arm your car silently. To do this on the Starline A9 or A93 models, you need to press the first key for a long time, and after the signal, click it again, but briefly. You can open the car in a similar way, but I use the second button on the key fob.

The complex also offers a silent security mode. In this case, the siren will not sound even when trying to break into the car - only the dimensions blink. The key fob will beep and vibrate to notify the owner of the situation. You can put the machine in this mode by pressing the first button for a long time, and then briefly clicking on the second key.

Disconnection methods

The alarm does not pick up at 20 meters and does not go off. The reason why the car is not disarmed may be a bad signal. In this case, the car simply does not have feedback from the key fob, and accordingly, it does not perceive commands. In this case, you need to check the condition of the power supply element of the remote control, perhaps precisely because of the weak signal, and replace the battery if necessary. Additionally, you need to check the area for radio interference.
There are also options when the siren goes off spontaneously. The reason for this behavior is that the shock sensor is too sensitive. Both stages (impact and hacking) can be adjusted using a standard screwdriver, reaching the sensor itself (it has special controls).
Sometimes autostart with automatic transmission does not work on the car, and SP lights up on the key fob display. This means that the car tried to start the car four times, but the starter simply did not have enough force. It is recommended to start it manually or increase the duration of its operation. In this case, for autostart it is necessary that the car is in neutral and the parking brake lever is fully tightened.
If the alarm does not work, and additional software errors appear (the car starts and stalls, does not close the doors, etc.), then it is best to reset to factory settings. After this, most of the problems should disappear, but if they cannot be fixed, then it is better to take the car to a specialized service, where qualified specialists will sort out the issue and fix all the problems, perhaps there is a mass loose or there is a bad contact somewhere.

Using the key fob, the alarm is turned off as standard, and using the service button - emergency (emergency). In order for the system to unlock the engine, which eventually starts, working power supplies must be installed in the remote control.

If you need to perform an emergency mute when the alarm mode is activated, use the key fob. When you press the button with the lock closed, the alarm will turn off the siren, the security will remain on.

To deactivate the siren while searching for the Valet button, you need to remove the terminals from the battery.

Why did he disappear?

In some cases, it automatically switches to silent mode. This can happen for several reasons. Most often, the siren turns off due to a sharp decrease in the car battery voltage. To prevent complete discharge, the system automatically switches to silent mode.

If the sound disappears, the reason may be poor contacts or wear of individual elements of the system, for example:

The limit switch going to the doors or trunk may wear out or rust;
the control wire broke during operation;
the shock sensor is not connected to the system;
wires going to the main unit are disconnected, etc.

Often such problems arise in systems that have been in operation for several years. In this case, alarm diagnostics is required.

Less often, the siren is turned off as a result of accidentally pressing the buttons on the key fob. This can be understood by the icon on the screen in the form of a crossed out speaker.

The key fob may also be faulty. However, it does not display complete information about the condition of the car. To check the functionality of the device, the following steps are performed. Remove the battery and then put it back in place. At this time, all available icons light up on the screen for a few seconds. If the crossed out speaker and some other icons remain turned off on Starline A91, A93, etc., then the key fob is faulty.

In this case, it needs to be repaired.

In most cases, when the siren turns off, it is recommended to contact a service technician to diagnose and troubleshoot the problem.

How to enable silent mode on A91

The Starline alarm system has an option that ensures silent operation of the device in the event of an attempted penetration or impact. To use it, you need to know how to turn on the silent mode of Starline A91. The action algorithm is as follows:

Long press button 1 with a closed lock drawn.

Click on key 2 with the lock open (briefly).

If everything is done correctly, the LED indicator on the car will begin to blink, and the side lights will light up once. In this case, all door locks are closed if they are connected to the alarm system.

In the case when arming without sound in the Starline A91 is completed successfully, a short signal sounds on the key fob, and a picture with a closed lock appears on the display, and next to it there will be a crossed out speaker.

Before turning on silent mode on the Starline A91, make sure that the hood, doors and luggage compartment are in the correct positions. If, after completing the steps discussed, they turn out to be open, the handbrake is not applied, and the foot brake is pressed, the alarm system informs about this with four sound signals and the same number of headlight flashes. A similar situation arises if any of the push-button switches for the doors, luggage compartment, hood or brakes fails.

Sometimes the silent mode of the Starline A91 alarm turns on automatically. This problem may occur in the following cases:

poor contact;
decrease in battery charge level;
damage to the control wire during operation;
violation of the integrity of the limit switch;
accidental pressing of buttons on the key fob;
disconnecting wires from the main unit;
lack of connection of the shock sensor or its disconnection. In this situation, the hammer will not even appear on the keychain.

In all the considered cases, silent security Starline A91 can be activated without the driver’s command. In this case, you need to figure out why the silent mode worked and how to properly fix the problem. Often such difficulties arise on alarm systems that have been in operation for more than 3-5 years. Of course, you can try to disassemble the key fob and check it yourself. But it’s better to go to a service station and carry out a full diagnosis.
