GM Lock code on dealer invoice?

On the dealer invoice is a number followed by "Key Nos" Is this the code for the cylinder lock?

How many digits should be in the punch code?

Is it typical to find this info on the dealer invoice?

One alpha character followed by three digits.

Yes - on the invoice and build sheet. They have to be able to make keys in case the originals are lost or stolen.

Just before KEY NOS is a 5 digit number. There is no alphanumeric letter.

Not directly under the box that says "Key No."?

Looks like "P568" and "S214" to me.



There should be two codes: one for the ignition key and one for the door lock cylinder.

Here's the build sheet for my '65 GTO, found on top of the fuel tank.

Key codes are shown (but redacted).
