all you have to do is sit in the car with all the doors shut, put the key into the ignition turn it to on (not start the position before start) then off six times leaving in the on position on the sixth time then press the lock/unlock button on the remote heads.. IMPORTANT NOTE: this puts the car into learn mode and all remote heads have to be present eg if you have two both wil need to be retrained by pressing the unlock/unlock button. i have used this method on astras vectras and zafrias. also works on opel and vauxhall as there made by the same company

My girlfriend recently had the same problem with her 2002 Astra. She just took it to the local dealer who reprogrammed it on the spot in a few minutes, at no charge.
