Key Replacement
Short answer: If you have the PHS billing history, it lists the four-digit ignition and trunk key codes — take them to a GM dealer, who can look up the cuts in the key-code book and punch a key. If not, the four-digit codes are stamped on the original door and trunk lock cylinders (the door matches the ignition, the trunk matches the glovebox).
Keys have six cuts with five possible depths each (read head-to-tip with the head to the right). Example: a 1967 ignition/door code 7W05 = cuts 532242; trunk/glovebox 2X52 = 431132. Dealers use a punch/notch tool (not a grinder). Correct 1967 blanks: “A” blank for door/ignition (octagon head, Briggs & Stratton logo), “B” blank for trunk/glovebox (rounded scalloped head). Dealers also stock tumblers to re-key any cylinder.
