Without any threat, a vehicle’s anti-theft system can be triggered and the engine immobilized. When the anti-theft system of your car won’t start, what should you do? Here’s what Car From Japan has to say.
Anti Theft System Car Wont Start: The Reasons
Your car is protected from theft and vandalism by the anti-theft system. This device is operated by an electrical circuit that disconnects when suspicious activity is detected. As a result, your car won’t start or even die any time soon if it interrupts the power supply.

Anti Theft System Car Wont Start: What To Do?
Can you tell me what I should do if the anti-theft system won’t let me start my car? There is a possibility that the system might trigger the car alarm or prevent the engine from starting without any apparent reason.
If it doesn’t work properly, you have to turn it off. It is not possible for the car to return to normal operation until the problem is resolved.
Check the battery
You should check the car battery as soon as possible if your anti theft system car will not start. There is a possibility that it is dead or low and needs to be charged. Hence, the key fob’s security code cannot be read by the car’s system.
Battery connections should be checked. Try to jumpstart it if they work. The problem is likely to be solved by this method.
Theft System’ light ON
When the ‘Theft System’ light is on on the dashboard and you can access the car’s interior, try this trick.
Turn the key slightly to the right after inserting it in the ignition slot. For a few minutes or more, leave it in this position. It is likely that the car will start and the light will be turned off.
A vehicle in this state has its engine running but its lights are on. This can be achieved by turning on all the necessary components, such as the radio and dashboard lights, which will enable the theft alarm to be bypassed.
Use the car key on the side door
Hold your car key for a few seconds after turning it to unlock the driver’s side door with your car key. It is sometimes possible to get past the factory alarm by using this trick. Having the original key lets the car’s system detect you as the owner.
The key fob can be used with a dead battery or a damaged key fob on most Volkswagen, Mercedes-Benz, and BMW models.
The trick needs to be modified if your Honda Accord anti-theft won’t start. The driver’s door lock should be unlocked, locked, and then relocked after placing the key in the lock.
Once again, turn it to the unlock position to disable the anti-theft system’s alarm. To reset the car’s alarm, let it run for at least 10 minutes after you start it.
Reset the car’s computer
Using this method, you can fix the situation where the car won’t start due to an anti-theft system. For a minute or two, remove the positive terminal from the battery.
It should be reconnected and the cathode and anode terminals should be tightened. Your car will likely start after it resets the computer system. Activate the factory alarm’s kill switch if the trick doesn’t work.
Use the key trick with the steering wheel
Service theft deterrent systems sometimes lock the steering wheel and prevent the key from turning. Hondas are mostly affected by this annoying problem.
Most often, it occurs after turning off the car and moving the steering wheel. When you try to switch on the car, the wheel becomes locked in that position and cannot be moved.
A wheel that is locked in one direction is likely to be stuck. You will be able to move it if you move it in the opposite direction. The car can be pulled in that direction if you try it. Turn the ignition key while inserting it into the ignition slot.
Pull hard on the wheel and keep trying with the key if the key is stubborn. It will be possible to start the engine at some point once the ignition is switched on.
Check the key
Cars with anti-theft systems may not start if the key itself is malfunctioning. An embedded chip in the keys transmits a code to the alarm system when inserted into the ignition.
A broken or damaged key will not work with that chip. Try another key if one doesn’t work. Check the transmission system at the dealer if nothing happens.
Using the key to start the engine is another trick you can try. The key should be left in this position for 10 minutes if the engine doesn’t respond or dies after starting.
Turn off the ignition when the security light comes on, wait 20 seconds, then start the vehicle.
Check with a code reader
Try reading the car code if you are still having trouble with your car anti-theft lock.
You can find out why the light is on with a code reader, just as you would with a check engine light. It is possible that your receiver isn’t receiving any power, or that it isn’t receiving a signal from the key.
While code reading does not provide the exact part or sensor to replace, you will be on the right path for a better solution after following directions without success.
