They're supposed to program it for you, I'd go back to the dealer. Should only take about 15 minutes, they use a computer to set it?

I'm sure someone will assist your key concerns over there.

This is primarily a vendor selling forum. The right people won't see it here.

I'm locking this thread as I'm sure the sale is over by now. lol

Alright I'm reopening this until further notice, but my goodness this thread is OLD.

In case you haven't found the answer, here it is (see pic, under "Toyota & Lexus"). This page was extracted from a key transponder PDF document (file was too large for attachment with the post). Keep in mind that this instructional pertains to 1998-2000 Lexus vehicles.
