Can I make a Master Key from Valet Key? Options

[skaufmann]

I only have the original Valet key that turns the ignition. I have a 2nd key (Master) that opens the passenger door (and nothing else) and a 3rd key (Valet) that open the driver door (and nothing else).

From what I can gather, the only difference between the master key and the valet key is the channeling down the side of the key, not the notch/tooth profile. If I'm correct, can I make a copy of the original Valet key to a new Master key?

My thought is it's easier to rekey the door locks and I suspect the new Master will then work the trunk and glove box since those were not likely replaced like the door locks were.

GPR sells originals & repros of the keys. Take the best key you have, and rekey everything to that key. Most places that make keys can make the copies. My local Ace hardware does them for me. Follow the rekey thread (it's in my signature) and do the rest of them. If you take the glove box lock out & use those wafers for the spares, then key the ignition, doors, rear trunk, front trunk then the glove box, in that order, you should come pretty close. If you need some extra wafers, at least the exterior stuff is done, so you can drive the car while you source the extras.
