Smile How do you program a "NEWLY CUT, main master key" on a Lexus ES300 2000?

Ok, I'm sure its been asked; but, at this point I cannot find my question in the forums: hence I ask here to see if anyone could help me with the step-by-step programming instructions on "NEWLY bought," main master key to a Lexus ES300, 2000? I have found instructions on how to sync a new key and fob if you ALREADY have "another master key," but this is a freshly made key (off VIN #'s) and is the ONLY master key. That said, I have only one additional fob (that works) and a 2nd key that is without a built in fob, which is the only key to that starts my car. Please advise? Renny

Dealership unfortunately. If you are saying the new key is the only master key you have, the dealer has to re-seed the keys. Basically swipe it clean and re-program all the keys.
