After my dad moved we lost our chevy dealership person back in Dubuque Ia that cut and and rekeyed lock cylinders for us.

This meant dad and I got to research how its done. Not terribly complicated, but you need something like a Curtis key cutter, the right cams and carriages, the key blanks and most importantly the key code book to take all your old lock cylinder codes and have keys made for them. On this car I had all the original glove box and door cylinders. I had to rekey the trunk to the original glove box and rekey the ignition switch to the doors.

All pretty straightforward as long as you can read the 4 digit GM code on the side of the cylinders. This was alot of fun to read up on and do.
