3. What triggers the anti-theft system in a car?
The anti-theft system can be triggered by tampering detected with the vehicle’s key cylinder. This can be caused by an invalid key, screwdriver, foreign key fob, or no key detected when trying to start the vehicle.
4. How do you reset the security system so the car will start?
To reset the security system, you can disconnect the car battery for a minute. Open up the hood, locate the battery, and with a wrench, remove the negative terminal. Then reconnect it after a minute has passed.
5. How do you know if your car is stuck in anti-theft mode?

6. How do I get my car out of anti-theft mode?
In some cases, the car’s anti-theft system is linked to a door lock mechanism. To disable it, you need to locate a small switch or release lever on the door panel and engage it. This will cause the car’s security system to be disabled.
