To reset the system, get in the car and close the door. Without starting the engine, turn the key to the Run position. Leave the key there for exactly 10 minutes. Without removing the key, turn the key to the off position and back to “Run” for 10 minutes.
If the security or theft warning light flashes when you try to start your car and the engine won’t start or won’t start, you have a theft problem. The system may not be recognizing your key or keyless entry beacon, or there may be a problem with the anti-theft module, keyless entry system, or wiring.
The anti-theft alarm light on your car’s dashboard should flash regularly to indicate that the system is on and active. You must lock the car’s doors (without it running) for the alarm to go off.
Your car’s anti-theft system may not work properly at any given time. This can be for many reasons, including a dead car battery that’s losing the memory of your key, or a dead remote control battery. It’s also possible that the immobilizer chip on your key or the car’s door lock is damaged.
