C3 ignition & door lock keys
Very early ('68 and at least some '69) C3's had yet a separate key (Briggs and Stratton)for the alarm
Hope this helps.





69 and up when they went to column ignition lock they used a
square for the ignition. The round is trunk/glovebox,spare tire carrier,
doors.
My 68 uses a Briggs & Stratton hex head for the doors and ignition.
A round lolipop head key for the spare tire tub lock and glove box
behind my seat.
There were different key blanks so no to duplicate so often.
A,C,E,G was ignition.
B,D,F,H were door/trunk key blanks.
There was a 5 digit key code used to cut the blanks to each vehicle.
If you walked around a parking lot back in the day with a say B cut blank you may very well find it opens some one elses car.
Just info we were told in the day

Hope this helped.
