any way to program new (black) master with just (grey) valet key?

Is there any way to program a new black master key for a 2002 toyota sequoia? I just purchase the vehicle used and it came with only the grey key. How can a program a new master key without paying my local dealer 200-1000 bucks. One person on this forum mentioned that he got it done for 50 bucks at his local dealer. He didn't state how and he doesn't accept emails. Anyone else out there have any ideas? Please help....

Since you only have a valet key, you can't use on board programming. This leave only 2 methods to add master keys, scan tool with proper software (I know somebody in Atlanta that can do this for you) or you could remove your ecu and have the chip reflashed to accept new keys, I can provide this service if needed.
