Ain't that the truth! Back when I was just out of HS in 1971, I worked at GE's Schenectady, NY plant (along with 29000 others). Went out to the parking lot after punching out, got in my '70 VW bug and started it up. Something wasn't quite right, and it was then I realized it wasn't my car! Mine was parked several rows over. Same model, year, color, and locks...A lock smith will have a pile of keys and just try one after another. Back then there really weren't very many cuts and in a little while you find a key that works. I did this myself one time with a 64 Impala my brother brought home, had a ring of keys and I found one that worked on about the fifth try.
Once you get it open you can remove the lock, take it apart and remove the small pins from the tumbler. This will allow the lock to be actuated w/any key (or even a screwdriver) but it does retain the look of an operational lock as opposed to removing the entire lock, leaving a hole that is an invitation for anyone to open w/a screwdriver.I have not tried going through the back seat yet..I know that the trunk has been closed for about 14 years...I didn't know if there was a rodders trick to popping the lock other than just picking it cuz I don't know how..I do appreciate all of the fast responses.. I will try and pu 'll the back seat apart andvtry to get in that way. Thank you
