thanks i tried it and it worked,
Tried the key in lock business didn't seem to work ..............Then tried key in lock - start engine - press lock button on remote - turn off - remove key -get out of vehicle - press lock button on remote - Voila, Bingo, Schazam, all systems go!
Saved me a trip to that hated Vauxhall garage hope it works for you.
