i lost my only set of keys to the 79, the doors are unlocked, but the trunk isnt , any ideas how to swap out the cylinders without damaging anything? or should i just call a locksmith? the ignition key is missing as well.

 

Just go to your local GM dealer and buy a new set of lock cylinders.

Take your door panel off and there will be a clip that you can use a screw driver to slid off the lock cylinder, manuver the cyliner out from the rod that actually locks the door and its out. The hardest part will be taking your door panel off. The trunk just has a clip as well. Your new cylinders will come with a brand new set of keys as well. The ignition I havnt ever done that one.

 

Call a locksmith first and tell him your problem. The cost of new lock cylinders for the doors, trunk and ignition might be almost as much as the cost to have the locksmith re-key the ignition and trunk. Plus the time and effort to remove everything.

He should be able to re-key both keys off the ignition and trunk cylinder and never even have to touch the door panels.

 

ill try the locksmith first!! thanks guys, someon also mentioned to me that the glove box key is the same as the trunk key and to use that to rekey the trunk, is this true?

 

a locksmith can rekey any cylinder form your car by taking one out. the glove box and truck are usually the say key if you haven't changed it before but also your door keys should open your truck also. it just depends if you don't want to do all the work which it is tedious than pay a locksmith which for them it is easy> I could do it but i live far away. a locksmith can do it and it would be cheaper than replacing 5 lock cylinder including ignition go with a locksmith not just saying it b/c that what i m going to school for but trust it would be easier on your wallet

 

yeah talked to a locksmith for 125 cdn, he'll rekey all the locks for me. saves me the hassle of trying to break into the trunk and to redo the ignition without the original key.
