My son would like a spare key for 02 reg corsa which he bought with only 1 key. Dealers seem to charge about £160 for a key which seems a bit steep.
I have found blank keys with transponder chips for around £10 on ebay, but these would need cutting and I guess the car would need some sort of reprogramming to use the new transponder as well, which I believe auto locksmiths can do. But I haven't found anywhere that supplies the section containing the remote switches/battery holder/circuit board that slides into the key body ? Can these be purchased anywhere, and will this require reprogramming as well, or just the usual resync procedure you use when the battery is replaced ?
Thanks Tony
