Q: Antijacking component

asked by on

The alarm on my car keeps going off, and I can't start it due to the antijacking components.

The anti-theft system may be experiencing a fault and in most cases will store a code pointing to the problem component. I recommend having a technician experienced in vehicle electrical systems check the vehicle and read fault codes. They will be able to diagnose the problem with your alarm to get your car starting again.
