Good point Gearhead, that hadn't occurred to me. Though, the 2 keys I receieved with the car look to be VERY old and beat up with lots of wear & tear (original, I'm guessing.)
The central locking appears to be working; if I push down manually on a door button, everything locks up fine & unlocks too.
Interestingly, the 2 keys I have are not identical and I presume one was meant to be a valet key, but one of my keys does not work in anything! Doors, trunk or ignition. Swell.
So what are my options? Lock cylinder replacement? Repair? Any help greatly appreciated in case I have to move to a high crime area.
