im locked out of my car!!! im having work done at the mo so it donest have an engine and no battery so the key fob is useless and my door lock has always been a bit iffy and now when i put the key in it doesnt do anything but i can hear a rattle in the door. the only option i can think off is to jack up the car get in underneath the bonnet and connect a battery so my fob will work but i really dont fancy that. can i take the handle off and get to the lock mechanism and use the key on that and try and connect up what ever is loose??
