Wes,
Try this to reset the immobiliser:-
Answer 1: By disconnecting and removing the battery and then replacing it, you activated the anti-theft device in your car. If you arm and disarm the anti-theft device, it should reset. If this does not work using the remote, try locking and unlocking the driver side door with the key.
Answer 2: Try locking and unlocking the rear hatch. This could reset your security system.
Answer 3: I removed battery from car to charge it. Upon returning battery to car, alarm activated itself. The car dealer told me to turn ignition switch on and off 5 times, to reset the alarm.
Answer 4:Try unlocking the drivers door with the key, which may disarm the alarm system.
If none of these work then post your question on this site, for assistance:
