Buick Regal: Immobilizer Operation
This vehicle has a passive theft-deterrent system.
The system does not have to be manually armed or disarmed.
The vehicle is automatically immobilized when the transmitter leaves the vehicle.
The immobilization system is disarmed when ENGINE START/ STOP is pressed and a valid transmitter is in the vehicle.

The security light in the instrument cluster comes on when there is a problem with arming or disarming the theft-deterrent system.
The system has one or more transmitters matched to an immobilizer control unit in the vehicle. Only a correctly matched transmitter will start the vehicle.
If the transmitter is damaged, the vehicle may not start.
When trying to start the vehicle, the security light comes on briefly when the ignition is turned on.
If the vehicle does not start and the security light stays on, there is a problem with the system. Turn the vehicle off and try again.
If the RKE transmitter appears to be undamaged, try another transmitter, or place the transmitter in the transmitter pocket.
If the vehicle does not start with the other transmitter or when the transmitter is in the transmitter pocket, the vehicle needs service.
See your dealer who can service the theft-deterrent system and have a new transmitter programmed to the vehicle.
Do not leave the transmitter or device that disarms or deactivates the theft-deterrent system in the vehicle.
