I just bought a 2004 GX470 from a Mercedes dealer. The only keys they gave me were a very worn, but fully functional, remote key, and a valet key.I have tried to get the dealer to pony-up for a new remote key, but they refuse to.
Obviously, I'm not content with having just one functional key, so I'm looking for advice on getting a replacement.
I bought a master key for my 2004 GX470 from SpareCarKeys.com:

The cost for the master key: $120 + $6 shipping
There is a possibility that you may need to have Lexus program it. My dealer charged $25. They will send you directions to do it yourself. But, it didn't work for me.
The key is as good as a new one from Lexus except it doesn't have the gold plating "L" on the outside.
