My trunk lock cyllinder was broke when I bought the car. I live in Germany but last week, my wife went back to the states so I had her pick up a new lock cyllinder at the Pontiac dealership. I don't know if this is what I was looking for. It's more like a kit. I count eleven pieces including some really small springs. The real kicker though -- no key!

Is there some way to magically set this thing to work with my door key? Anybody have instructions for putting this all together? The part number is 1239-8672. Shouldn't it have come with a key? Why would you sell a lock cyllinder w/o a key?

Please advise. Crawling back and opening the trunk from the inside is kind of embarassing.

 

BTW, it's an '86 for what its worth.

 

I still don't have a working trunk lock cylinder... (mine has the remote release thankfully)... When I went to order one from the dealer, they only offer it like that... You have to have a locksmith key it or something.. Not sure, didn't want to deal with it at the time, and haven't gotten to it yet.... hope this helps...

 

I just replaced all three of mine, and had the dealership rekey them for me.

 

Did your rear lock cyllinder come in a dozen pieces or already assembled? If un-assembled, how hard was it to put together?

I think I will try a local Opel dealer but most likely, I think I will have to mail the cyllinder back to the states to get it keyed.

I still think it's assinine that they don't provide a key with the cyllinder. More-so that the dealer didn't point this out in the first place.
