Why won't it start from auto start?
There may be an error in the key fob itself. The error can be resolved by replacing or repairing the key fob. The battery of the alarm key fob may also be dead. It can also be damaged by a fall, impact, and so on.
A failure may also occur in the software package. Then you will need to reflash it.
- For many people, the problem disappears after replacing the battery.
- You need to check the condition of the harnesses and terminals.
- The problem may be a faulty ignition system.
- The alarm may not be configured correctly. To solve the problem, you need to reconfigure the modes. Everything must be done according to the instructions prescribed by the alarm manufacturers.
- The car may not start through autostart and due to a problem with the spark plugs. It is possible to view the condition of these spark plugs only after dismantling them. If you can see that there is some kind of plaque on the candles, then you need to wash them in a special solution. This problem can be solved by replacing old spark plugs with new ones. They change the spark plugs in the car after driving more than 30 thousand km.
- The throttle valve may become clogged. From time to time it is necessary to clean it. This can be done using carburetor cleaners.
- Problem with autostart. You can set a higher temperature using the remote control if there are temperature sensors. In this case, the machine will heat up on its own.
- A factory reset may be to blame. You need to go to where the alarm was installed and ask to solve the problem. This error is resolved quickly.
Temperature control button malfunction. The temperature sensor may break. It just needs to be replaced with another one. Owners can install the sensor not according to the instructions.

The influence of temperature outside the window
Autostart may not start at sub-zero temperatures. To do this, you need to check the power contacts on the alarm. They can oxidize and therefore normal voltage is not maintained.
- The battery may be damaged. Then you should buy a new one.
- If there is some kind of break in the ignition circuit, then the car may not start on frosty days.
- The immobilizer reader may not work.
- No need to panic. First of all, you should check whether the car starts normally. If everything works as it should. The problem is with the alarm. We need to check everything. You should look at the wire cross-section.
Urgent Actions
If all the settings are in order and the engine still does not start, go to the VALET service mode, which switches the alarm system to when the car is returned for repair.
- The ignition key is turned on and off again (the engine does not start, but there is electricity in the electrical circuit);
- The service mode switch button must be held for 15 seconds;
- The alarm beeps and the LED lights up and stays on;
However, in some cases, the magic button does not work and the motor remains indifferent to all your squats. There is another way to temporarily bring it back to life - an emergency shutdown. This is done in a similar way, only from inside the cabin: hold down the VALET button for 15 seconds, the LED flashes and goes out, we have one more attempt to start.
In the most difficult situation, this step also does not help. Then there are 2 options: either call a truck, or call friends and acquaintances to find an auto electrician online. Those who have done the latter claim that his unlocking services are cheaper than a trip on a tugboat. In addition, many services in this case give a discount on further handling of your alarm.
Autorun is not set at the required time
This problem occurs if the clock in the security system becomes out of sync with the correct time. If you look at the time depicted on the keychain and the present, you can notice this. The problem can be solved very simply. You need to set the correct time.
Description of the operating principle
So, the alarm is blocking the engine from starting, what to do in such a situation and what is the cause of the malfunction? Most often, this happens when the car is equipped with an immobilizer or two-way alarm.
Firstly, this type of fault may be caused by a fault in the alarm system itself, i.e. The anti-theft system did not recognize the key the first time. Moreover, the problem may lie much deeper than it seems at first glance. It is imperative to understand that many modern cars are equipped with a native “alarm”, which is directly connected to the electronic engine control unit. But let's take our time and see if everything is ok.
Autostart for cars with manual transmission
Next, we will look at the reasons why cars with manual transmission cannot start from auto start or from the key fob.
- Autostart for cars with manual transmission may not work if the driver has incorrectly activated a function such as program neutral. To solve the problem, you simply need to activate software neutral according to the instructions.
- The alarm may not be installed correctly.
- Door limit sensors may not work.
Incorrect setting of alarm operating modes
The second most common reason for autostart failure is incorrect setting of the vehicle security alarm operating modes depending on the set time, clock time, temperature readings, and commands from the remote control. Modes should be changed in accordance with the operating instructions provided by the manufacturers included in the alarm kit.
In addition, a violation of the operating settings may be caused by a malfunction of the remote control or temperature sensor, which incorrectly transmits readings to the autostart unit. These devices must be diagnosed, reprogrammed, or repaired/replaced.
Triple flash instead of auto start
If the headlights blink three times, it means the electrical voltage in the circuit has decreased. There are several reasons for this action.
The cause may be a dead battery. Or the terminals on the battery may become acidic. The third reason may be that electrical circuits that were very long or with an inappropriate cross-section were used to connect the alarm system.
It is necessary to carefully inspect the plug pads. Carefully examine the condition of power electrical circuits.
If no problems are found during inspection, then the wires are checked. They may have the wrong cross-section.
The alarm was not set correctly
You should also check the functionality and correct installation and connection of the security alarm system. Its malfunction may be due to:
- natural wear and tear of modules, wires, terminals;
- incorrect connection to the engine control circuit
- incorrect/incorrect connection to the power cable;
- incomplete connection of the ignition switch and starter (the alarm does not correctly simulate the ignition switch);
- The alarm bypass transponder does not read the signal.
In each case, it is necessary to conduct a complete diagnosis of the electrical circuits of the security alarm system and connect them correctly.
Can't start with key fob
Next, we will consider the actions that need to be taken if the car cannot be started using the key fob.
- The condition of the batteries on the key fob is checked. They may run out. And replacing them will help solve the problem.
- There may be some damage on the key fob. Maybe he was dropped or hit. You need to autostart using an additional key. If the problem is with the key fob, you can take it to a workshop or buy a new one.
- You can re-register the key fob. Do this according to the instructions. If you can’t do it yourself, then turn to specialists.
- The problem may be with the temperature sensor. You can try to solve the problem by setting it to a higher temperature.
- You need to check that the immobilizer bypass is connected correctly. The problem is resolved by changing the number of turns. We also need to see if there are any breaks in the wires of the crawler system.
Reasons for blocking
If you are confident in your knowledge of electrical circuits, you can try to figure out what went wrong with your system yourself. The most likely of them:
- blown fuses. Just in case, they are first checked and replaced;
- uncharged battery. This means that it has not gone out completely, a beep may sound and the headlights may come on. But the crackling sound of turning the key is the activation of the intake relay and blocking of the engine, which is also his fault;
- Temperature sensor (if connected to the alarm). To check, just turn over the sensor installed under the hood;
- trunk or hood limit switches. They are prone to oxidation in high humidity (spring or autumn). Although experts believe that this phenomenon is due to crudely inaccurate installation of the alarm system.
However, it should be borne in mind that the reasons for the irregular operation of the system may lie much deeper. In particular, you may find that it has already been removed and needs to be replaced, or its sensors may be covered. If the options you have tested do not give the desired results, it is better to contact a service center: they will know exactly what to do if the alarm blocks the engine from starting.
How to fix problems
- First of all, you need to check the battery charge. If the charge is weak, then autostart may not work correctly. To fix the problem, carefully inspect the terminals and various connections. The level of the electrolyte is also checked. The charge level of the battery is checked with a device called a multimeter. Its level should not be less than 13.5 volts. If upon inspection it is clear that there are scratches on the case, then the problem can be eliminated by replacing the battery. Upon inspection, you will notice that the electrolyte is at a low level. Then you will need to top it up. If the charge is weak, then you need to properly recharge it.
- The status of the buttons is inspected. You need to check what level the charge is. If the reasons are minor, then the remote control can be disassembled, errors corrected, and cleaned. Broken parts are replaced with new ones.
- If moisture is noticed, the device is disassembled and dried. You cannot dry it on a radiator. This will damage the communicator.
- If necessary, change the battery.
- It is necessary to carefully inspect the key fob display. Maybe some pictograms appeared there. Finding them will help eliminate the causes.
- You need to check whether the system is working normally.
If the temperature outside is sub-zero, autostart may not work due to the condition of the battery.
No successful startup after four attempts
ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"
If the car alarm attempts to start the engine, but it starts and stalls or does not show any signs of starting, then after four unsuccessful attempts the starline stops trying to start the power plant. The reasons for this situation may be:
- lack of an immobilizer bypass;
- the key placed in the bypass module is poorly read or missing;
- errors that occurred during the installation of a car alarm, as a result of which the processor module does not receive information about the operation of the motor.
Troubleshooting depends on the nature of its occurrence. You should check whether the immobilizer is bypassed and the transponder is readable. You also need to make sure that the wires coming from the main unit are connected correctly and check that they comply with the programmed parameters.

Ignition system
If we talk about old cars, it is quite possible for the distributor cover to break. As a result, the “runner” cannot interact correctly with the wires, and the spark simply does not flow to one or more cylinders.
Also, do not rule out breakdown of high-voltage wires. This is very easy to determine. At night, white and blue sparks on the wires should not appear under the hood. If this is the case, it is worth replacing the set of high-voltage wires. Another reason that the car does not start the first time is the coil. It can be the same for all cylinders, but on modern cars a separate coil is installed for each spark plug. Typically, coil breakdown occurs due to increased moisture. This element is non-separable and can be replaced entirely with a new one.
How to check which coil has failed? This will require a special tester. But it’s better to install a new one and check the quality of the start. As practice has shown, even with a faulty coil, the engine will start, but poorly. But after installing the new one, the engine starts with half a turn.
Fuel system
Poor engine starting may be due to a dirty fuel filter. As you know, there are two such elements in a car. This is a coarse and fine filter. As a rule, the last element is clogged. This happens at a mileage of about 60-90 thousand kilometers. The filter itself is a corrugated paper element with micropores. They are the ones that hold dirty particles. Over the years, these pores become clogged and the pump is no longer able to pump gasoline through the filter. What is the solution to the problem? The solution is obvious - replacing the fuel filter with a new one. This is the only way to guarantee quick and trouble-free engine starting in any conditions.
Among the less common causes of poor starting, experts highlight contamination of injectors (applies to diesel engines) and injectors. In this case, replacement will be expensive, so many owners prefer ultrasonic cleaning of these elements. But this is done only at specialized service stations.
note
Whatever the reason for poor engine starting, do not forget about the main rule. Do not turn the starter for too long in an attempt to start the car. This has a negative impact on the battery. If it is not new, then in a couple of attempts you can “plant” it altogether.
To prevent this, you should rotate the starter for no more than 4-5 seconds. And the interval between starts should be about 30 seconds. Remember that when deeply discharged, the battery significantly loses its capacity. And it will not be possible to resume it in the future.
