How did you manage to lock keys in the car any way?
I did it in my 16v - got a concept 500 alarm, made a funny noise so I got out, popped the bonnet and revved it from the engine bay.
Of course as soon as it hit 1,500 rpms the door locked on me. With the engine running and keys in it.
Luckily my mate was with me and he waited while I ran home in the rain to get the spare key.
