Why it doesn’t work and how to disable or unlock the Alligator car alarm

Modern anti-theft alarm systems of the Alligator brand are highly reliable, however, from time to time, the driver may suddenly face an unpleasant question: how to unlock the alligator alarm?

The problem can creep up unnoticed, suddenly the car does not start or is not armed. Suddenly, for no apparent reason, the alarm starts screaming and flashing the parking lights. The situation is unpleasant, especially since it is often associated with loss of time and disruption of plans. It is useful to become familiar with possible malfunctions in the anti-theft system in advance and find out how to turn off the alligator alarm.

How to reboot and set up the alarm

The need to configure and reboot the alarm occurs if it starts to fail.

The best decision would be to carefully study the instructions for this equipment and strictly follow its recommendations. However, instructions may not be available. Resetting the settings can help in such trouble. This procedure for resetting the alarm key fob consists of several basic steps:

1. The most important and first step is to turn off the engine.
2. Find (if you didn’t ask in advance) a small button called Valet. When installing anti-theft equipment, they try to hide this button away from prying eyes. It is most likely to be found under the “dashboard” near the steering column.
3. Press the service button 9 times, the siren will grunt briefly once, and the “dimensions” will blink twice.
4. Turn on the ignition. At the same time, the headlights will light up and the siren will croak briefly 9 times. This means that the system has entered factory settings mode.
5. Briefly press the Jack once. The siren will respond once with a loud short sound.
6. On the remote control, click on the button with the speaker. A long sound from the remote control will indicate that the factory settings have been completely reset.
7. Turn off the car's ignition or wait until the alarm exits the reset mode on its own. The side lights will beep briefly several times to confirm the completion of the procedure. The melody of the control panel will sound synchronously with them.

It must be borne in mind that incorrectly disabling the alligator alarm will lead to absolute blocking of the system. It is unlikely that you will be able to unlock it on your own and you will have to resort to the services of competent employees of special workshops. Therefore, you should not take risks, but immediately seek help from service centers.

Alligator pager with one-way communication does not work

The Alligator two-button alarm key fob is equipped with a minimum of functions and is usually used as a spare unit. Some pagers may have additional keys. With its help you can open the car and arm it. Popular models.

1. A-LIGHT – on the case there are two main buttons and auxiliary keys located vertically. The pager allows you to set the silent mode and block the engine.
2. M 2200 – equipped with three buttons. The body is small, elongated, ergonomic in shape.
3. NS-505 is a three-button pager, all keys are located in the center. Powered by the Keeloq encryption system.
4. A-1 S is a standard three-key switch. A budget option with a classic set of features.
5. A-2 S – outwardly no different from the previous one, equipped with options that the first one does not have. Works at a distance of 50 meters.
6. A-3 S – the third generation is the most advanced of the budget series. There is an anti-theft function called Anti-Hijack, and there is a dynamic anti-hacking code.

Sometimes it happens that the second key fob fails - possible culprits are listed in the table.

How to disable autorun

Auto start is a useful feature of modern car alarm systems. This option is especially valuable in winter. The car can be started and warmed up without driver intervention. By the time he arrives, the engine and interior will be warmed up, the windows will thaw and be cleared of ice and snow. The conveniences of such a system are obvious, but it is not without its drawbacks, which sometimes force car enthusiasts to disable autostart. The reasons for this decision are the following circumstances:

1. The car engine starts and stops more often than usual. Starting the engine in cold weather increases its wear, reducing its service life.
2. Frequent operation of the starter drains the battery.
3. During autostart, some locks of the anti-theft complex are removed, therefore, the car becomes vulnerable to theft.
4. The system begins to glitch, the car sometimes starts unstably with the ignition key.
5. Periodic starting and stopping of the engine leads to the accumulation of condensate in the exhaust system and increases corrosion of the muffler.
6. Autostart only works when the gear is in neutral, otherwise the car will not start. Therefore, a car with a manual transmission must be set to the parking brake. In frosty weather, brake pads sometimes freeze to the brake discs or drums.

For these reasons, the question arises: how to disable autorun?

The system can operate in two main modes:

1. Manual remote. It is controlled by a key fob at a distance of up to 350 m. There are models that work using mobile communications through special applications.
2. Auto. The launch is controlled by a timer or an engine or ambient temperature sensor.

You can reset the alarm by entering the service mode. To do this you need to do the following:

1. Press the key fob button for two seconds. The display will light up and a single short beep will sound.
2. Select the “Timer” mode, the device will beep once. Set the value to "0".

Similarly, enter the temperature setting mode by setting the value to “0”.

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.

How to disable panic mode

Panic mode can be activated during the following alarm modes:

• “Security activated”;
• “Security is off”;
• "Service Valet."

To activate the “Panic” state:

• turn off the ignition;
• keep both transmitter buttons with the images “Lock closed” and “Lock open” pressed simultaneously for 3 seconds;
• The alarm siren will sound and both turn signals will flash.

To deactivate the “Panic” mode, perform the procedure in the following order:

• -briefly click once on both buttons with the images “Lock closed” and “Lock open” synchronously;
• -the siren and turn signals will turn off. The system will return to its original state.

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;

• 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.

Ways to disable alligator alarm

There are two ways to deactivate the Alligator security kit:

• using a keychain;
• method of controlling the system in service mode by entering a password by pressing a key a certain number of times.

With keychain

If the security does not turn off, the easiest way to disable the alarm is to use a key fob:

1. Briefly press the “Lock open” button. The siren will sound twice and the headlights will blink. 2.The door lock will be released. The interior lighting will come on and go out after 30 seconds.
2. The power unit is unlocked by entering a password according to the instructions for a specific model of the security kit.

By timer

If it is impossible to use the key fob, turning off the autostart of the car using the timer is performed according to the following algorithm:

1. Start the engine by holding down the “Lock Closed” and “Snowflake” icons simultaneously for 3 seconds.
2. Wait until the signal sounds once and the direction indicators blink twice.
3. Press down on the crossed out horn. A triple signal will sound.
4. Within 5 seconds, hide both pictures “Castle closed”, “Snowflake”.
5. The successful completion of the autostart disabling procedure using the timer will be indicated by the headlights flashing three times.

Emergency shutdown without key fob

It happens that it is not possible to reset the settings on the remote communicator. This may be caused by its malfunction, or a strong level of radio interference. A simple sequence of actions will help you resolve the crash of the screaming system:

1. Open the driver's door with the key.
2. Get in the car.
3. Disable the security system.
4. No later than 15 seconds later, find Jack and click on it once.

If the procedure is correct, the security function will be removed.

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.

Features of disabling alarms of different models

The article presents the most general principles of anti-theft manipulation. It is necessary to take into account the nuances of handling various modifications of such kits. For example, in the M550 and LX440 variants, the system shutdown code consists of 2 digits, while the S250 kit uses a single-character encoding.

Alligator m550

The procedure for deactivating the security state consists of the following steps:

1. Use the key to open the car. The siren will blare. The turn signals and interior lights will flash.
2. The key starts the engine.
3. Within 15 seconds, you must first enter the first digit of the password, after a few seconds the second digit is entered. The password can be specified either using a communicator or using Jack.
4. When the system recognizes the entered password, the siren will stop screaming, and the blinking LED will also go off. If this does not happen, you must repeat the entire above procedure again.

Alligator lx440

The security system is activated as a result of the implementation of the following algorithm:

1. The driver's door of the car is opened with a key.
2. The key is turned in the ignition, the engine starts and immediately turns off. The countdown to blocking begins.
3. The Valet emergency button is pressed within 10 seconds a number of times equal to the first digit of the password.
4. The ignition turns on and off.
5. In the next 10 seconds, you must have time to enter the second digit of the password by pressing the emergency button.
6. At the end of the procedure, restart the ignition again.

Alligator s250

In this modification, the procedure is similar to the previous ones, only a unique password is entered. At the end of the manipulations with entering the secret code, you should start and stop the engine.

Malfunctions and their elimination

The anti-theft alarm kit is a high-tech electronic device. Despite its reliability, individual components periodically fail. If it is not possible to seek the help of certified specialists in this field, the user can try to solve an unexpected problem on his own.

Why doesn't it turn off?

If the alarm is not disarmed, first of all, you must try to reset the alarm using the Valet emergency button. To reset the settings, you need to enter a unique password that the car owner must know. At the beginning and at the end of entering the code, as a rule, the ignition is switched on and off for a short time.

The problem may be with the communicator. The most common causes of its occurrence:

• insufficient battery charge;
• problems in the key fob chip;
• high background radio interference.

Radio interference at a similar frequency can suppress the security system signal. Typically, the source of high radio noise is power lines or the same signal signals of neighboring cars. You can try to bring the communicator as close to the control unit as possible. Sometimes long and frequent pressing of the shutdown key helps. The weak signal is duplicated and amplified.

Key fob diagnostics

The driver carries the key fob with him at all times. At the same time, he is exposed to a number of unfavorable factors. Dust, dirt and moisture gradually penetrate into the communicator body, damaging the microcircuit tracks. They become dirty or cracked. You should disassemble the communicator body and carefully inspect the device. The circuit needs to be cleaned and dried. Solder the tracks, having previously “ringed” the tracks for integrity. For this purpose, you can use a regular household tester (multimeter).

The same tester can measure the battery charge level. If it is below normal, this may be the cause of the malfunction. A dead battery must be replaced with a new one.

Doesn't close the door

If the security mode is activated and the remote control signals this, but the doors are not locked, it means that the central locking is faulty. In this case, you will not hear the characteristic click of the doors locking. First of all, you need to check the fuse responsible for the lock circuit. Perhaps it burned out or broke in the cold. The locking drive solenoids could be broken. You should also check the functionality of the limit switches that signal open doors.

In addition to the above, the cause of the breakdown may be a break in the cables of the power supply circuit of the lock drive. Sections of the circuit must be tested with a tester. You should also check the connectors.

Doesn't work when the door is open

If the alarm does not respond to the opening of the doors, you need to check whether the interior lamps come on and whether the corresponding signal about the doors not being tightly closed turns on on the dashboard. If the light does not light up, the reason most likely lies in the limit switches and connecting connectors. To eliminate a permanent problem, the limit switches and connectors need to be disassembled, cleaned with fine sandpaper, wiped and dried.

The alarm behaves unpredictably

The unpredictable behavior of any system is the most difficult fault to diagnose. The most common reasons why the security system periodically fails:

1. Low battery charge.
2. Oxidation of limit switch contacts and connectors.
3. Malfunction of the communicator circuit or control unit.

The first two points can be corrected on your own. If electronics break down, you must contact specialized centers.

Alarm works but no confirmation

If commands to set security modes are executed. but there is no sound or light confirmation, then first of all, you should check the functionality of the siren and lights. To do this, they are disconnected from the signaling system and connected directly to the battery. If this and subsequent checking of the limit switches and connectors did not solve the problem, it obviously lies in a processor failure. It should be sent for diagnostics and then repaired or replaced.

Presence of radio interference

You will not be able to unlock the car if there is radio interference that does not allow the signal produced by the remote control to reach the main communication point. Interference can be caused by car alarms, which, for example, are located in a parking lot, or by other types of radio wave sources at a similar frequency. A cause of this kind can be eliminated in a fairly simple way. You will only need to bring the radio transmitter closer to the area where the main unit that ensures the operation of the ALLIGATOR alarm system is located (the unit itself is located next to the driver’s seat), and then again try to unlock the car.
