Somebody must know how to do this. I have 2 extra remotes that I would like to program for my Highlander. How do I do it?

If it is the Toyota system you cannot. You have to take it to the dealer and have them use their computer to program them to your truck. Call around and see hou much they charge. You might get lucky and find one that will charge you for 30 minutes of labor. I believe you need to bring all the Fobs with you that you have.

you should sell them on ebay and make some extra cash. Dealer price for those are around $300 each.
