Vauxhall Opel Car Key Reprogramming

Please note the following instructions are for re-synchronising remote keys. This allows keys originally supplied with the vehicle to be reprogrammed if they should go out of synchronisation with the car's code. Keys can go out of sychronisation if the battery has been changed or the button has been pressed numerous times out of range of the vehicle.

It will NOT reprogram the remote facility on a newly supplied key or second hand from another vehicle.

1. Sit in the car with doors closed. Place the key into the ignition and turn to Pos II (lights on)

2. Now press the lock button on the key remote with the key still in the ignition for about 2 secs

3. The central locking will now lock then unlock to show the remote control is now synchronized
