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.

If I recall correctly, the glove box and front trunk are the only ones that the master key protects...
May also be the rear trunk, but I have never found that to be true.

BUT
None of my cars where ever keyed correctly...so I have been chasing the keys forever anyways.

Re-keying a lock may have a classic thread that someone did...I seem to recall McMark did one.

If you have enough parts, you can rekey all the locks to match the new key...they are just tumbers that get replaced with the key in the tumbler...keep swapping them out until they all sit flush with the tumbler housing.

you should be able to buy the correct blank master keys from George Hussey at Auto Atlanta...
If not, there is a key guy that shows up at Hershey every year who only does these keys....
you should be able to find him at Pelican Parts, or possibly the Samba.

Also, I believe the Porsche dealer has the proper blank keys.
