Basically I've got a new car, came with the original remote locking key but no spare. I got a spare key made, they just copied the transponder signal from the original and into a new key with a transponder already inside, easy.

I've managed to get an original spare key but I obviously need the correct transponder chip signal so it works.

Can I get just the transponder chip with the with my signal copied over (like before) or can I get the transponder chip currently inside re-programmed.....OR can I hack away at the key I got made and get the chip out of that one?

EDIT: I can obivously just go the the place I got the spare key from and ask if they just do the transponder chips but I was just wondering if anyone has done it?

I'd want to get the signal in the car changed (and subsequently your keys) in case the owner hung onto the spare so that they can come round one night and take the car back. But that is possibly because I listen to too many paranoid people and it seems to rub off.

Yes, it does.

My prevous car didn't have the orignal spare key (it was a copy) and I also still have all the details of the previous owner. He was a nice guy, I know you can never tell but trust me.

Nevermind, I went with option C - Hack away at the spare I got made and take the chip out of that.

Zang!
