Many car owners, when purchasing a new car, install a Starline A61 Dialogue alarm system in the car. StarLine car alarm is an excellent choice in terms of price/quality/theft protection. At the same time, the alarm system in the car is often set to very high sensitivity, as a result of which the alarm is triggered by passing vehicles, which causes great inconvenience.
The StarLine A61 alarm kit includes a two-level shock sensor. A two-level shock sensor allows you to record external influences on the car and instantly transmit information about them to the owner. The piezoceramic two-level shock sensor ensures stable operation and resists electromagnetic interference.
The impact sensor separates strong and weak impacts on the vehicle thanks to two control zones. When there is a slight impact on the body or wheel of the car, a warning, short siren signal is heard. A strong impact on the vehicle will activate the alarm. Many car owners do not want to waste time and money turning to a car service center for such nonsense - adjusting the alarm sensitivity; In addition, sensitivity is individual for each car owner - some want greater sensitivity; For some, less sensitivity is enough.
How to adjust the sensitivity of the STARLINE alarm StarLine A61
You can adjust the sensitivity of the STARLINE A61 alarm yourself; The main thing is to find where the shock sensor was installed when installing the alarm. In the installation instructions for the StarLine A61 alarm system, the manufacturer recommends installing the alarm shock sensor in the base of the steering column. Most official services follow the instructions - install the shock sensor at the base of the steering column - under the steering wheel closer to the clutch pedal. The shock sensor is equipped with two very fine adjustment mechanisms with which the sensitivity is adjusted. To change the sensitivity, you need to take a thin Phillips screwdriver and slightly turn the mechanisms to the left (to decrease sensitivity) or to the right (to increase sensitivity).

How to determine the correct alarm sensitivity and adjust the sensor
A piezoceramic two-level shock sensor operates on the piezoelectric effect - the sound wave must reach them from an impact (on the car body) with the least attenuation. And this will happen if the shock sensor is attached tightly and to the metal connected to the body. In this regard, some service centers recommend mounting the shock sensor on metal. To adjust the sensitivity, you must first reduce both zones, add a warning zone (opposite the green LED), put the car in the armed state, wait at least 40 seconds; gently (and noticeably) hit the machine (avoiding jamming the metal;)), if the sensitivity is insufficient - add, if the sensitivity is excessive - decrease. Using the same scenario, set a full alarm zone.
Many car enthusiasts, when purchasing a new car, prefer to install the Starline system, which provides protection against theft. When installing an alarm system in the cabin, it is often set to a very high sensitivity threshold, as a result of which the system is triggered by vehicles passing nearby or bad weather conditions. The standard alarm kit includes a two-level shock sensor, which records all external influences and automatically transmits data to the owner.
The sensor system allows you to analyze two control zones and divide them into weak and strong influences. If you lightly touch the wheel or body of the car, the alarm system will notify you of the fact with a short signal. A strong blow will activate the alarm. But, based on numerous external factors, Starline can cause certain failures, which are caused by the excessive sensitivity of the system, and the alarm goes off on its own.
General provisions for setting up the system
The sensitivity of the Starline alarm is adjusted independently. To do this, you need to find a specific position for installing the shock sensor. The instructions state that the manufacturer recommends integrating the recognition system into the base of the steering column. The sensor is equipped with two fine adjustment mechanisms that allow you to adjust the sensitivity. To do this, use a standard Phillips screwdriver. To decrease the indicator, the mechanism turns to the left, and to increase, respectively, to the right.
The reasons for the constant alarm activation are:
- The default alarm sensitivity settings are set to the extreme maximum.
- Poor fixation of the alarm unit and shock sensor. To solve the problem, you need to re-secure them to a hard surface. They should not dangle or hang.
Important: If setting the sensitivity does not help and the control unit is firmly fixed, but the problem of constant alarm operation remains, this indicates that the sensor is broken. You need to contact a service center to replace it.
Determining alarm sensitivity and adjusting the sensor
The two-level sensor installed by default in the Starline system operates on the so-called piezo effect. The sound wave reaches the body of the car even before the impact. This is ensured only by tightly fastening the sensor to a metal element directly connected to the body. To adjust the sensitivity, both zones are reduced, but the warning zone located opposite the green indicator is added. After that, the car is set to security mode and after 40 seconds you need to carefully hit the body.
This action will indicate the level of sensitivity - if it is excessive, then it must be reduced. The same procedure is carried out to establish a full alarm zone. The maximum sensitivity indicator of the alarm and warning indicators of the shock sensor corresponds to the value 14. The minimum indicator (coarsening) is 0.1. A value of 0 disables the shock sensor completely.
4. How to temporarily disable the shock sensor
To disable the Starline A93 shock sensor, you must first deactivate the warning level, and then the alarm level. Everything is done with the security mode turned off.
Instructions for disabling and enabling the sensor.
1. Double-click button 1, i.e. briefly press the key 2 times. This step will disable the warning level.
2 Repeat steps. The alarm level of the sensor will be deactivated.
3. If you need to turn on the sensor, press key 1 again 2 times.

Reducing sensitivity
If the car is equipped with a standard alarm system by default, the location of the control unit and shock sensor can be found in the service book. Otherwise, the best way out of the situation will be to point to the Valet button, from which the wires extend. You can use them to find systems. The control unit will be mounted in the pedal assembly area. To reduce sensitivity, it is important to locate the control element on the unit that is responsible for this function. It is necessary to set the indicators slightly above the average limit and not lower than 4-5 units. Otherwise, the warning system will not work properly, and as a result, the sensitivity will become extremely weak and will not be able to transmit a signal about serious damage to the body and wheels of the vehicle. Another important factor in the level of sensitivity is the position of the antenna module. When installed on the windshield, the system is virtually eliminated from triggering in the event of a heavy impact on the wheels and the rear of the body. Setting the system parameters is done by simply moving the module to another part of the glass, followed by an impact test.
In the domestic market of automobile safety systems, one of the most popular products is the products of the Starline company, which have increased functionality and a long service life. Among the numerous line of this manufacturer, the one that has a secure two-way communication channel and a high-quality control unit, which, with timely maintenance, is able to reliably perform its functions, is in great demand among car enthusiasts. It often happens that the car owner does not carry out the necessary preventive maintenance in a timely manner, as a result of which various malfunctions appear in the operation of the Starline alarm.
6. Purpose of the button on the antenna
The Starline A93 antenna module, like other alarm systems of this brand, is equipped with one button that serves as a service button. With its help you can:
- enter your personal code;
- perform a hidden activation of the anti-robbery mode;
- write key fobs into the alarm memory;
- activate security mode without a key fob;
- enable automatic engine start based on voltage.
We also advise you to study in more detail the Starline A93 service mode, which is necessary when contacting service centers for repairs and maintenance.

Security system breakdown options
Many drivers are familiar with the problem when the Starline A91 alarm does not respond to the key fob, which can occur both after a short or long period of parking of the car. In addition to this alarm malfunction, Starline A91 breakdowns can also manifest themselves with other symptoms, namely:
- triggering the alarm of the security system by itself, without any reason;
- not closing the doors when the key fob indicates they are closed;
- constant signaling of loss of communication between the key fob and the alarm control unit;
- the inability to enable the “valet” service mode in the system.
Any of the above problems and breakdowns can lead to the inability to operate the vehicle, which causes many problems for car owners, but at the same time, each of them can be eliminated independently by carefully studying the methods of diagnosing and repairing the security system.
How to identify and change a dead battery in a key fob
The first thing you need to do when the alarm key fob does not work is to pay attention to the state of its battery, the insufficient charge of which is not able to ensure full signal transmission to the security system unit and, accordingly, it will not operate. You can determine the state of charge of the power supply by the dimming screen of the key fob or on the corresponding indicator icon. This malfunction can be eliminated by replacing the battery, after which the key fob can be fully used. It is changed using a small screwdriver, which is used to unscrew the screw connecting the halves of the key fob to each other. Having unscrewed the screw, the key fob is carefully disassembled and access to its power element is opened, which must be picked up and pulled out from the workplace, installing a new one there, and reassembling in the reverse order.
What to do if the alarm does not go off from the key fob
Quite often it can happen that the alarm system does not see the key fob after replacing the battery in it or turning off the power supply to the vehicle's on-board network by removing the battery. This means that there was a memory failure in the security system, as a result of which all key fobs previously registered in it were erased. In this case, it is necessary to restart the process of recording key fobs, which is performed as follows:
- The location of the service button of the security system control unit is located, it is pressed seven times and the car ignition is turned on. After which the system siren will emit seven beeps.
- After this, on the key fob itself, buttons No. 2 and No. 3 on the key fob are simultaneously pressed and held until the moment when the siren in the car and the key fob itself emit one sound signal, which means the end of the recording process in the memory of the control unit. Next, the alarm should begin to fully operate from the key fob buttons.
Starline a91 main keychain
If this does not happen, it means that the key fob itself or the internal parts of its antenna are faulty, which are not capable of transmitting radio waves with the required power. In this case, you need to purchase a new key fob with a display and record it in the memory of the security system device.
Why does the security system go off for no apparent reason?
One of the most common problems of many security systems and, accordingly, the A91 is that the alarm goes off on its own for no apparent reason, which is due to increased sensitivity, the so-called, which has several settings options and is located in the vehicle’s interior. To carry out independent diagnostics of the sensitivity of the sensor settings, it must be turned off, for which you will need to perform the following steps:
- On the key fob with the display, press button No. 1 with a short double press, after which the car’s headlights should blink twice, and the key fob will emit a short sound melody and display on the icons the shutdown of signals from the shock sensor, called the first level.
- Next, the second level of sensor adjustment is turned off, to do this you need to press button No. 1 on the key fob twice again, after which the car’s head optics should blink three times, and the key fob should emit three short beeps and display icons for temporarily turning off the shock sensor on the display.
5. Temporarily disabling the tilt sensor
How to turn off the Starline A93 tilt sensor - press key 3 twice. To turn it on, just do the same.

5.2. What is dh off, dh on on the key fob
When working with a tilt sensor, it will be useful to know what dh off and dh on mean on Starline A93. The inscription dh off means a temporary shutdown, and dh on means the sensor is turned on. The first inscription is displayed on the key fob screen when you press button 3 twice for the first time, the second, respectively, when you press the same button for the second time.
How to adjust car alarm sensitivity
The required sensitivity of the car alarm is set using the regulator located on the body of the shock sensor, which, depending on the model, can be a push-button or in the form of an adjusting screw. The setup process looks like this:
- The negative terminal of the car battery is disconnected or the fuse responsible for interior lighting is removed, this will avoid possible battery discharge.
- The location of the sensor itself is located, which is most often mounted under the front panel, closer to the pedal block, after which the alarm system is switched to service mode with the “valet” button.
- The sensitivity setting scale has 10 options, in which 0 is the minimum and 10 is the maximum value. During installation of the security system itself, its sensitivity is set to a value from 4 to 5, as the manufacturer recommends, and the setting can be changed no more than 10 times.
- When starting a gradual decrease in sensitivity, it is necessary to take into account the weight of both a fully loaded and unloaded vehicle, thereby ensuring the absence of false alarms.
During this procedure, special attention must be paid to the mounting location of the shock sensor, which must be mounted directly on the vehicle body; if this is not the case, it must be moved.
How to connect
The sensor is attached to a metal body panel in the passenger compartment using screws or 2-sided adhesive tape.
It is not recommended to install the element on moving plastic parts or vehicle wiring harnesses due to a decrease in measurement accuracy.
The device is placed openly, which provides access to the rotating elements for adjusting the sensitivity of the shock sensor. The accelerometer is located together with the transceiver unit on the inner surface of the windshield (at a distance of 50 mm from the metal elements of the body).
The connection harness (consisting of 4 wires) is routed under the car interior trim. To connect to the processor unit connector, a standard harness block is used. To switch the transceiver unit, a plug with 5 cables is used; on the processor unit, the plug is installed in connector X8.
Why don't the doors close when I press the key fob?
The problem in which the A91 alarm does not close the doors is either burnt fuses or faulty wiring, or a mechanical failure of the central lock itself. You can check the operation of the central locking using the key, inserting it into the driver's door and closing the car; if successful, it means that the lock is working.
After checking the functionality of the central locking, it is necessary to inspect all electrical wiring connectors from the alarm control unit going to the driver's door. Often the problem arises precisely because of poor contact in the connectors, or check all the fuses of the security system; if burnt ones are found, simply replace them with new ones.
What are they used for?
Structurally, the shock sensor is a small compact device. In most cases, the sensor is almost invisible. Install it on areas of the machine that are most likely to be subject to shock.
When a shock or sudden movement occurs, the sensor is triggered, activates the alarm, and sends a warning signal to the car owner via the control panel or directly to a smartphone.
The sensor will respond to any movements that cause the surface where the device is attached to vibrate. The reaction occurs in a matter of moments, and the driver receives the appropriate information.
The main task of the sensor is to prevent crime, among which it is worth highlighting car theft, hijacking, damage to property, unauthorized entry into the vehicle, etc.
How to eliminate incorrect operation
The problem of periodic incorrect operation of the A91 may be a partial failure of various settings, for which they must be re-entered. To do this, reset to factory settings using the “Valet” button:
- After turning off the car ignition, press the “Jack” button 9 times;
- the ignition is turned on and the siren will emit 9 signals;
- “Jack” is pressed 1 time and after the signal, button No. 1 on the key fob is pressed 1 time, after which all settings are reset.
Happy owners of this protective system ask what to do if the Starline a91 shock sensor is triggered? Moreover, the bewilderment of the people is clearly expressed: the system was not installed yesterday, it worked well for several months, and here we are.
It seems that the installers are not to blame (after all, it worked!), but many were unable to understand what caused the “sides”. It is also puzzling that the alarm is raised irregularly - a car can stand quietly for hours, and then sound a signal a couple of times in about 20 minutes. There are even more mysterious options: it only goes off when the handbrake is on, for example.
What to do if the Starline a91 shock sensor is triggered
, depends on what exactly caused the phenomenon. The most common options are listed below.
Sensitivity:
When faced with a false alarm, the first thing you should try is to adjust the sensor settings. Perhaps it is too sensitive and reacts even to a heavy car passing by. Even if “before” everything worked fine and was set as it should, the settings could simply go wrong for reasons beyond your control.
Incorrect installation
Most often, if the owner set the alarm himself. And here two mistakes can be made:
- The cables of the sensor itself and the communication module are located too close to each other. To solve the problem, in many cases it is enough to simply move them further away;
- unreliable fastening. Often, to make it faster, the sensor is hung on wires or attached with tape. It is undoubtedly easier to install this way, but you cannot expect correct operation from a Starline installed this way;
- mounting on plastic. Even if the sensor is securely fixed, but on a plastic part, it can give false signals: when the temperature changes, the plastic sometimes crackles as it cools down, which causes an operation. The manufacturer's instructions strongly recommend using a metal steering shaft pipe for installation.
If the whole point is these mistakes, the solution to the problem is elementary - reinstall the sensor according to all the rules (by yourself, carefully following the instructions, or by contacting specialists). Moisture:
Here the observed picture is somewhat different: when it is warm, the shock sensor is triggered; when it is cold, there is a signal that the car has been opened. The reason identified by several car owners is the locks getting wet, no matter which door - even on the trunk. In the summer, condensation short-circuits the circuits, in the winter it freezes and causes a different reaction. To “treat” you will have to find out which of the locks is causing the failure and carry out the appropriate repair work: remove moisture, lubricate and insulate the detected cracks.
Effect of time:
Naturally, it is worth checking how much time has passed since the alarm was installed.
Nothing lasts forever in this world - including sensors. In addition, they are quite fragile and short-lived. It might be wiser to even try replacing the sensor first, and if that doesn’t help, check other versions. Other reasons: The saddest thing is if you received a sensor from a defective batch. It's easy to check: turn the sensitivity down to zero. If the alarms do not stop and independent “dancing with a tambourine” does not help, you should not be lazy, but make a claim before the warranty expires. Either they will replace it or fix it.
