there is a 4 digit code on the lock cylinder, that should help identify the 6 number of key cuts.....GM uses 6 cuts, not 5......
normal GM cars have flats on the ignition key edge and oval for the trunks/glove box.....The key number ignition is decided by the year ....10/12, 40, 42, 46 ect with flats on the edge
whats on the cylinders?

Key code books
I just checked my code book and It goes at least to 1980....somewhere along the way GM advertised keys with anti theft or chips in them....I`m not sure on those after 1980 didn`t check

Each key from both sets has the 'GM' insignia on both sides that you can barely see in the pic. The square keys are stamped 'J' and the round keys are stamped 'K'.

I have both original sets ... one very worn set that is on my everyday key ring (as seen in the pic), and another that hasn't seen nearly as much use. Neither set has 'cars' or 'Curtis' or 'B-46' or a '4-digit code' (that I can find).
Each key from both sets has the 'GM' insignia on both sides that you can barely see in the pic. The square keys are stamped 'J' and the round keys are stamped 'K'.

Thanks for the information. My problem is that my ignition gas been changed and I do not have the original key. I have a non original key for the ignition that is now in the car but I do not have a key of any kind that fits the door locks. I am going to have to take a door panel off and get the lock cylinder out and then have a key made to fit it and then rekey the ignition to match the door key. That is the only way that I can figure out how to do it. The one key that I do have that does look original is the one that I described above with the word Curtis and B-46 stamped on it but it does not fit the doors or the ignition.
