Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

I have a 51 plate Comfort. Recently I have had the buzzer sounding when the key is removed from the ignition. I have replaced the battery in the key fob and carried out the synchronizing of the remote control - pressing the lock or unlock button with the key in the ignition. It worked fine for a few days but it's all started again and I cannot repeat the remote synchronizing to stop it, even for a short while.
Does anyone have any suggestions please?

with it being a comfort im guessing its a corsa c
your best off trying the corsa c forum, or even check your manual see that it says!

sorry i cant help bud

Thanks, I'll try the Corsa C forum. The manual says 'put key in ignition and press lock or unlock', which I detailed but to no avail.
