Good point ainars, I'd forgotten that. Is it simple to identify the chip and move it to a new key? I've swapped batteries but never looked at the other bits inside.
I now recall doing similar things with my old Ford Focus which had the same generation technology and pairing remotes was really simple if the immobiliser was already valid. Though in that the immobiliser chip was very obvious, separate and easily moved to a new key. Ford used 2 different but compatible versions; earlier ones were in a sort of tiny glass phial which "could" break but later ones were solidly embedded in plastic.
Definitely worth trying to start the car with the damaged key though, you can probably unlock the door with the blade.
Alarm might go off but should stop once the car is started, or unlock with the working remote on a first test?
