I need to replace the trunk lock on my 91 chevy lumina apv

The best price I found for my '92 was here: http://www.partstrain.com/store/?PN=7606&N=0&VN=+4294966993+4294965994+4294967234+4294967247+4294966340&Nr=AND(year:1992,make:Chevrolet,model:Lumina%20APV,submodel:Base,engine:6%20Cyl%203.8L,universal:0) It was only $37 & works great. I didn't rekey it to the rest of the doors, so I have another key on my ring. Maybe someday I'll get it rekeyed to match but I doubt it. Hint: Once I got the trim panel off the door, I brought the door down to a nearly closed position so I wasn't working overhead.

New lock cylinders may or may not be available from the aftermarket for your 1991 Chevrolet Lumina. You will need to check with your local parts suppliers to find out. No mater where you get your new trunk lock cylinder you will need to have the lock "coded" to your key. Some GM dealers may do this or you may need to see your local locksmith. With the new lock cylinder codded you will need to remove your old trunk lock and install the new one.
