    Dealer if you don't have any keys that's already programmed into the system. Bring ownership paperwork and ID. I believe even an automotive locksmith requires that you have at least one programmed key to get into the system to add or delete other fobs.

    If it was as simple as pulling a fuse to program another key fob into your car - car thieves would be doing this all day long..... Dude where's my car....

    Just saying....

    Locksmiths listed on the NASTF Vehicle Security Professional Registry are eligible for the Techstream subscription level they can use to reset with no keys on hand. Of course they're supposed to make you prove it's your car.
