From my past experiences with old door and ignition locks,the keys are usually lost or worn smooth. And the locks themselves are just dirty. I have a string of over 100 G.M. keys(abt 130)
and what i usually do is clean the lock as best as possible,,then go thru my keys till i find one to fit. I then have a copy made at ACE Hardware,,,,,back in business.
Ive been the route with the repro. waste of money junk,,NO MORE.
