I have an astra G/Mk4 I had to replace the drivers door barrel as it had a lock change and the remote key supplied only worked the ignition and locked and unlocked the car via the remote.
Problem I now have is that I can still lock and unlock the car with the remote on the key which also arms and disarms the alarm,
when I lock the car with the key that works fine and arms the alarm but if I try to unlock it with the key the alarm goes off - the key will not disarm it only the remote.
its a standard sri 2.0 with standard vauxhall alarm fitted.
please can someone help or make a suggestion or 2, or 3
