Owners of Alligator security systems are often faced with the need to remotely control the engine start during the cold season or during long-term parking. Autostart is one of the most popular functions of modern car alarms, allowing you to warm up the interior and engine before driving. Correct activation of this option requires a clear understanding of the key fob operation algorithms and the sequence of actions on the part of the driver.
Systems Alligator are famous for their reliability, however, for the starting mechanism to work correctly, it is necessary that all connections be made professionally. In this article we will analyze not only the standard procedures for turning on the motor, but also the nuances of programming parameters that are often overlooked during initial installation. Understanding these processes will help you avoid situations where the car refuses to start when commanded.
Before you begin activating functions, make sure that your vehicle is equipped with the appropriate immobilizer bypass module and engine monitoring sensors. Without these components soft launch is impossible, even if the key fob is working. Let's consider in detail all the available control and configuration methods.
Basic button combinations for starting the engine
To activate remote start on most alarm models Alligator (L, M, C series) the standard key fob key pressing algorithm is used. Typically, you need to press and hold the button with the image of a snowflake or star for 2-3 seconds until a melodic signal sounds. After this, the system interrogates the sensors and, if safety conditions are met, supplies power to the starter.
In some modifications, especially in budget series, a double press may be required: first, a short press on the “F” (function) button, and then a quick press on the power button. Time interval between presses is critical and should not exceed one second. If the system does not respond, the lock may have been activated or the battery in the key fob may have run out.
There is also a method of starting from the main key fob with an LCD display, where the operation is confirmed visually. The corresponding icon should appear on the screen, and the status indicator should blink a certain number of times. This allows the driver to be sure that the command was accepted by the central control unit.
⚠️ Attention: If, when trying to start, the starter makes several revolutions, but the engine does not catch, the system may make one or two more attempts at specified intervals. Do not press the buttons repeatedly randomly, so as not to confuse the algorithm.
Programming autorun parameters through the menu
In-depth configuration of the system is carried out through the service menu, which is accessed in programming mode. To enter this mode, you usually need to turn on the ignition and press the service button Valet a certain number of times and turn off the ignition. The number of presses depends on the specific model and is specified in the instructions, often 3 or 4 times.
After entering the setup mode (confirmed by a characteristic sound signal), you can change the starter operating parameters. Using the key fob buttons, you select the desired function and then set its value. For example, you can set the amount of time the starter will run when trying to start, or how long the engine will run before it automatically stops.
☑️ Configure launch options
It is important to correctly set the type of engine control. The system can be guided by the tachometer (engine speed), generator (voltage in the on-board network) or noise threshold level. Diesel engines often require an additional delay setting before the starter engages to allow time for the engine to warm up. glow plugs.
Below is a table with examples of commonly used programming functions for various alarm series:
| Function | Description | Value options |
|---|---|---|
| Engine type | Choosing between petrol and diesel engines | Gasoline / Diesel |
| Work control | Method for detecting a running engine | By generator / By tachometer |
| Opening hours | Duration of engine operation after starting | 10 min / 20 min / 30 min |
| Automatic transmission delay | Delay time for diesel cars (Kalina) | 0 sec / 3 sec / 6 sec |
After completing all settings, you must exit the programming mode by turning off the ignition. All changes are saved in the non-volatile memory of the control unit and remain active even after the battery is disconnected.
Before changing autorun settings, take a photo of the table of factory values in the instructions. This will allow you to quickly return everything to how it was if the new parameters turn out to be inconvenient.
Temperature trigger: setting the temperature sensor
One of the most useful functions for the Russian climate is starting the engine when the temperature drops. To implement this, the system uses an external temperature sensor, which is usually installed in the engine compartment. Activation occurs automatically when the temperature drops below the set threshold.
To enable this mode, you must activate the corresponding function in the settings menu. Temperature thresholds can vary: -5°C, -10°C, -20°C or -30°C. The choice depends on the condition of the battery and the quality of the engine oil in your car. Too frequent starts with a weak battery can lead to its complete discharge.
When the function is activated, a snowflake-shaped indicator usually lights up on the key fob display. The system will check the engine temperature at certain intervals (the polling frequency is also configurable). If the conditions are met, an automatic start will occur.
⚠️ Attention: Make sure that the temperature sensor is attached to a metal part of the engine and does not touch hot pipes or the exhaust system. Incorrect installation will result in incorrect readings and false starts.
Using a timer and alarm to start
The periodic timer start function allows you to start the engine at regular intervals: 2, 4, 12 or 24 hours. This is useful if you leave the car for a long time in the cold and want to maintain the temperature of the antifreeze and oil. Activation is carried out through the function menu or a special combination of buttons.
The alarm start mode works differently: the engine will start once at the time you set on the key fob clock. This is convenient for those who like to get into an already warmed-up car at the exact appointed time. For this function to work, the clock on the key fob must be synchronized with real time.
If someone opens the door while the timer is running, the start will be blocked. Also neutral gear must be prepared in advance (for cars with manual transmission).
"Software neutral" procedure for mechanics
For vehicles with a manual transmission, the “soft neutral” procedure must be performed before leaving the vehicle. This is a mandatory safety condition that ensures that the car will not move when started by the starter. The essence of the procedure is to leave the engine running with the ignition key removed.
The algorithm of actions is as follows: stop the car, tighten the handbrake, press and release the security disarm button (or the special “snowflake” button, depending on the model). The engine will continue to run. After this, you can remove the key from the ignition and close the doors. The system itself will stall the engine after a programmed time (usually 30 seconds) or immediately after closing the doors, maintaining readiness for autostart.
What happens if you don't implement software neutrality?
If you simply turn off the ignition without preparation, the system will assume that the car is in gear. When trying to autostart, the starter will not turn on, or will turn on for a short time and stall, since the motion sensor or brake pedal limit switch will not give permission to start.
Some drivers ignore this step, resulting in remote start failure. If you forget to complete the procedure, you will have to go out to the car, get into the cabin, start the engine manually, turn it off and repeat the entire preparation cycle again.
Diagnosing problems: why autorun does not work
If a command is sent from the key fob, but the engine does not start, it is necessary to analyze the system’s response. Most often, the reason lies in one of the blocking factors. Alarm Alligator has a developed diagnostic system that reports the cause of failure by the number of LED flashes or sound signals.
Among the most common reasons are:
- ⚡ Discharged car battery: there is not enough voltage to crank the starter, the system detects a voltage drop below the threshold and aborts the attempt.
- 🚫 “software neutral” has not been fulfilled: relevant for manual transmissions, the system “does not see” readiness for a safe start.
- 🔑 Problems with the immobilizer bypass: the standard car protection system blocks the start because it does not see the “original” key in the ignition switch area.
- ❄️ Freezing of cables or mechanisms: in severe frosts, the gearshift lever or throttle may jam.
It is also worth checking the door, hood and trunk limit switches. If the system “thinks” that the hood is open (due to a faulty sensor), autostart will be strictly prohibited for safety reasons. Visual inspection of wiring and contacts in winter often helps to identify oxidation that interferes with the passage of the signal.
90% of problems with autostart are associated either with a discharged battery or with incorrect execution of the procedure for preparing for a manual start.
Frequently asked questions (FAQ)
Is it possible to configure autorun without the Valet service button?
You cannot change the settings yourself, without access to the service button, since entering the programming mode is done through it. However, if the button is lost or faulty, it can be replaced by an experienced electrician by closing the corresponding contacts in the control unit connector, but this requires disassembling the dashboard.
How many times in a row will the system try to start the car?
Standard setting for alarms Alligator assumes 3 startup attempts. If the engine does not catch on the first try, the system turns off the ignition, pauses and tries again. After three unsuccessful attempts, the system is blocked and sends an alarm to the key fob.
Is auto-start harmful to a car engine?
Short-term engine operation at idle speed without load is practically harmless for modern engines. However, if the engine does not have time to fully warm up to operating temperature and stalls, moisture may condense in the exhaust system and dilute the oil. It is recommended to set the operating time to at least 10-15 minutes.
Why does the key fob show starting, but the car is stopped?
This means that the command left the key fob and was accepted by the alarm unit, but the unit itself did not send a signal to the starter. The reason is the blockages: the hood is open, the neutral is not installed, the battery voltage is low, or the immobilizer bypass module is faulty. You need to look at the car’s reaction (flashing turn signals, sound of siren).
