Would probably be not too expensive to mail the cylinder to the US and have a HAMBer take care of it for you, but if you have the code,then that could be done elsewhere,too.
So are you saying you can start the car without the key? Like the lock is broken? If so, you may need more than just a key.
lots of those GMs back then had an ignition lock that had three positions: Lock, Off, and On. If you remove the key when it's in the Off position, then you can switch it to On without the key, but you can't move it to Lock, and anyone can drive the car without the key.
I went out to the shop and found my bag of old locks. Here are the cylinders from some...the long one is a door lock from a 50s chevy truck, the smallest is a glovebox lock, and there is an ignition lock cylinder in there, too. The common theme is that you have to get the lock cylinder out of the barrel, to see the stamped number. The funniest part of the situation with the locksmith not wanting to work on it, is that the fellow is trying to make it so he can lock the car...not unlock....it's already unlocked.
The PO of my '50 chevy panel truck shaved the driver/passenger door key locks but left the key lock on the cargo door(s). The truck literally can't be locked. I'm just careful where I park it and what I leave in it. It does have an ignition cut-off, but still......?
Psst! Drey......check the post dates. This thread is a year old. (Yep, I've been caught with that, too.) Roger
