It would have to be read. If it is a key with the remote fob then it is most likely a master. You need a 4D68 tp29 chip for a Lexus master. The valet and master keys have different chips.

Hoping Mauser can chime in as he seems to have knowledge in this area.

While this might help, corporate can't force a dealer to do anything.

The key on the right can be added as a master.

Awesome. I did notice that when I hooked up techstream, it recognized my ecu as a landcruiser. Would that complicate things?

.You should be able to manually choose your vehicle from the drop down menu.

You could go to Toyota and not the Lexus dealer.
