I just bought a used Toyota Corolla 2013 (manufactured 2013-03) but it only came with one key. Now I might be a little bit paranoid, but since I can't be sure that the seller kept another key I would like to know if there is a way to invalidate all the keys except mine (AFAIK these are chipped keys)?

When you get your new key programmed for your Corolla (ref: this question), they can have any other keys programmed out of the vehicle. It has to be done with a special programmer.

  • Is this something a car locksmith can do or only a Toyota dealer can?

    If the locksmith has the right programmer, they can do it. I believe a programmer which can add the G-chip key can also remove them. The OBDStar Key Master or the like should be able to do it. Commented Jun 17, 2017 at 21:10
