Key Blank or Key Codes Table for 1972 Corvette
My dad and I are trying to bring his 1972 Corvette back to life. It's been sitting in the garage for the past 38 years. Over that time, the keys have been lost, and we're trying to get some new ones made.
We read that the key code is written on the hand manual, and ours indeed was! It's a 4 character code (number-letter-number-number). We took this code to our town's reputable locksmith, who cut a key. However, the key doesn't even fit in the slot (neither door nor ignition). I'm not an expert, but I think it was cut on the wrong blank. The locksmith used a B48-A blank. Based on my research, a 1972 corvette needs a 320652 54-C blank to work in the ignition (http://www.camaros.org/keysandlocks.shtml#systems). The locksmith did seem confused about the blank at first, so I think it's possible he used the wrong one. Before I go back to the locksmith and embarrass myself, I'd like to confirm that a 1972 Corvette definitely needs a 54-C key, assuming the locks are original. Alternatively, if someone can point me to where I can look up the key cut / blank needed based on a key code, I'd be interested to see that table. If that's not possible, I can also just send someone the key code, although I guess I was trying to avoid putting that out there on the internet, whatever that's worth. Thanks for the help. The fallback option is bringing a mobile locksmith out to pull the steering column (was quoted $300). I've been trying to access the doorlocks but two screws are stuck pretty tight and I'm afraid of stripping them. With the key code, that should be avoidable, right? |
I got a key cut and it was the wrong size did the same thing it was too thick

I removed the alarm switch from my 73 and took it to a real locksmith. They were able to open up the switch and make two new keys for me. For the ignition and door locks I had keys, so I purchased the correct lettered blanks on eBay and had the locksmith cut them for me.

Key blanks are still available from all GM parts departments.

No need to mess with the steering column. Remove either the right or left door lock cylinder and take it to a good locksmith. Locksmith will be able to make a key based on the set up of the cylinders tumblers. Your new key should fit the ignition since both the doors and ignition were identical from the factory.
|
Even a new, correct key may not always work so well in an badly worn, correct lock; dangling heavy keychains can/will damage ignition locks.
|
Door cylinder would be correct code if the car still has the original ignition lock cylinder.
The 4 digit code must be "converted" through the set of books related to the model year and if not mistaken the actual model of car. I used to cut keys with the hand punch all the time when I ran the service center for a rental car company back in the late 80's early 90's. |
