You can turn off the Alligator alarm in your car using the key fob or using a special button to enter the service mode if the communicator is faulty. The latter method may require a personal password, which is assigned after installing the anti-theft system. Depending on the model of the security system, the procedure for entering the code on the car may differ, but the principle is always the same - the number of keystrokes corresponds to the number.

Disabling using the key fob

Remote switching off of functions and unlocking the car engine is carried out using the remote control buttons in this way:

1. Using button 1 of the key fob, the standard unlocking of the ignition system and door locks is performed. You need to disarm the car by briefly pressing the button. In “signals” with a frequency of 434 MHz, the shutdown principle is similar if the main communicator with two-way communication is used, and not an additional one.
2. Using the second key, you can turn off the silent protection of the car if the system was previously turned on in this mode. Pressing the control element must be short-term.
3. If the alarm was temporarily turned on, any button can be used to deactivate it. However, the door locks can only be unlocked after pressing the first control.

Learn more about how to disable the Alligator alarm after closing in two steps:

1. When approaching the vehicle, you need to press the first button on the signaling remote control.
2. The anti-theft siren will sound twice, and the external lights will also flash twice. If the alarm was able to block the doors before, the blocking should be automatically removed. When the protection is temporarily disabled, the LED indicator on the instrument panel will blink rapidly. The lighting system in the car interior should turn on for 30 seconds.
3. The alarm will continue to block the power unit, preventing it from starting.
4. The following actions depend on the settings of the security system and the presence of a personal password. If the code is disabled, the engine can be started.

Important Features

Intellectual hacking is a fairly serious problem of our time. Smart robbers simply scan the security system, guess the code and unlock the car. With the anti-grabber function, no one can do such a scam. The dynamic device control code protects the signal from interception, working for the benefit of property safety. The alarm is controlled at a distance of up to 2 km in relation to the car.

A rich option of modes helps control the device, adjusting it to the desired mode. For example, if the driver leaves the car in a dangerous place, he can use the passive engine blocking function. This function eliminates the possibility of starting the car under any influence on it. The engine can be turned off remotely; to do this, you just need to use the control panel. This procedure can be carried out automatically and will not cause any damage to the car.

Features of disabling alarms of different models

It is important to know

The M550 and LX440 models use two-digit coding (the security system is normally assigned a PIN code of 11). In the S250 version, the password usually consists of one character.

Alligator M550

Guide to emergency disabling of the Alligator 550 car security system:

1. The driver's door in the car is opened with a key. The security system will turn on the siren, the turning lights and interior lighting will begin to blink.
2. The key is inserted into the lock and the ignition is activated.
3. Over the next 15 seconds, the car owner must enter the first digit of the password. To specify a code without a transmitter, use the “Valet” service mode button.
4. After entering the first digit of the password, there is a pause of several seconds.
5. The user then specifies the next character of the code.
6. If the password is successfully entered, the alarm mode will turn off and the LED light will stop blinking. If the security is not disabled, then the code was entered incorrectly.

Alligator LX440

You can restart the 440 without a code with one press of the “Valet” key. However, this must be done within 10 seconds after activating the ignition.

If you have a personal code, deactivation is performed as follows:

1. The key opens the driver's side door lock.
2. The user must insert the key into the switch and activate, turn off, and then turn on the ignition system again.
3. Within 10 seconds, the emergency mode key is pressed several times to indicate the first character of the code.
4. The ignition system turns off and then turns on again.
5. In the next 10 seconds, the user must have time to enter the next digit of the code.
6. Then the ignition is turned off and on again.

Alligator S250

Entering a personal code on the 250 model is performed in the same way as on the Alligator M550 version. However, after the procedure for disabling the protection, you will need to start the motor. Only after this the “signaling” will turn off.

The buttons are blocked

On the following Alligator alarm models, you can enable button blocking from accidental pressing:

• A 1;
• A 3;
• A 3 S;
• A 9;
• C 300, 325;
• TD 350;
• M 1500;
• C 500;
• S 725 RS, 325;
• D 910;
• S 250;
• M 2200, 975;
• S 850 RS;
• M 2200;
• S 875RS;
• M-2 T;
• S 200;
• M 800;
• S 400;
• D 930.

Sometimes the lock is accidentally activated by pressing the buttons at the same time or due to a short circuit with condensation. How to unblock:

• hold down F and at the same time the open and closed lock key;
• The lock is placed in the same way.

Alligator alarm problems

An overview of the causes of malfunctions in feedback systems, as well as recommendations for their elimination:

1. If the alarm does not work or does not close the doors properly, this may be due to radio interference in the area. In such cases, the system will not be able to turn on the security mode at all, or the door locks will be locked when the key fob is as close as possible to the transceiver. To fix the problem, you will need to emergency unlock the alarm and then drive the car to another location. The appearance of interference is associated with the presence of industrial enterprises, large shopping centers, transformer substations or airports.
2. The system may not set the security mode as a result of incorrect installation of the components of the anti-theft complex. For example, if a transceiver with a built-in antenna is located near electronic equipment or metal objects, the alarm range is significantly reduced. In some cases, the system stops receiving signals altogether. To resolve the problem, the transceiver module must be reinstalled in a different location according to the requirements specified in the service manual.
3. If the alarm does not disarm, the problem may be due to a low battery in the remote control. Sometimes the system does not turn off at all or does not turn off every other time. If the power source is not completely discharged, the alarm system “glitches”, but periodically performs its functions. To restart the options, you will need to install a new battery in the transmitter.
4. The problem may be damage or malfunction of the key fob itself. The first thing to do in such cases is to disassemble the device and check the integrity of its structural components. Failed keys and elements on the board can be seen without testing the remote control with a multimeter. To replace components, parts are resoldered. The cause of the problem may be wear on the contact tracks, which will also have to be re-soldered.
5. The remote control may not operate correctly due to exposure to moisture or clogged contact elements. In this case, you will also need to disassemble the device and dry its board in a warm and dry place. Prolonged exposure to moisture can lead to destruction of circuit elements, in which case a complete replacement of the device will be required.
6. Alarm malfunctions are sometimes caused by a low car battery. The user needs to open the engine compartment and check the integrity of the device - if it has cracks, it should be replaced. Then the electrolyte level in the jars is diagnosed, after which liquid is added if necessary. If the battery is discharged, the battery is recharged or replaced.
7. Control unit malfunction. In case of problems of this nature, only one of the doors can close. The failure can be fixed by an electronics specialist, since the module will need to be re-flashed. The user can solve the problem if it is clogged or oxidized contacts on the module.

The Pavel Kalinin Autodiagnostics channel in its video talked about the nuances of diagnosing microprocessor modules of security systems.

For what reasons can a car alarm be faulty?

At the very beginning, we should acquaint our readers with the reasons for breakdowns due to which the car cannot be removed from the security mode using a simple Alligator key fob. The most common problems may be:

1. Presence of radio interference;
2. The radio transmitter (key fob) for the Alligator car alarm could turn off;
3. The car battery was in a discharged state.

How to reset the alarm?

To reset and reset parameters to factory values, do this:

1. On the communicator, the star and trunk open buttons are pressed simultaneously. These elements must be held for three seconds.
2. If the values ​​are successfully reset to factory settings, the siren will play a double beep. All parameters will be reset, except for the personal code.

It is important to know

You can reset the parameters or reboot the alarm by disconnecting all connectors from the control unit. After disconnecting, you need to wait a few minutes, then reconnect the pads to the module.

Possibility of discharging the car battery

In order to find out that the root of the problem lies in the car’s battery itself, you will have to get into its interior. This can be done using a key that opens car doors. If the battery is completely discharged, then after the doors are open, the car alarm will not work, but your further actions will be accompanied by the sounds of a siren.

Removing the system from protection mode by encoding

The removal of a vehicle from security is carried out through a PIN, which is a two-digit or four-digit number. Typically, with factory settings, the pin number is two units, but the user is free to change it.

To unlock this way, you need to do the following set of actions:

1. First, the engine ignition is activated.
2. Then press the Jack button as many times (for one digit) as is written in the code combination;
3. After ignition, the operation is repeated for another number.

What is it for

During the operation of the security system, situations often arise when it is necessary to reboot the Alligator. It is advisable to do this work in the following cases:

1. Malfunctions.
2. Inability to set the required parameters.
3. Buying a car from another owner.
4. Suspicion of car hacking (signal interception).

In all the considered cases, you can reboot the device and return it to factory settings. Subsequently, you need to set all parameters from scratch.

Knowing how to reset the Alligator alarm, you can always return the device to functionality and reset the data. Such actions can help in case of temporary system failures or other unusual cases. In the comments, share your experience and methods that allow you to return your car’s protection to its original parameters.
