Recommended Ways to Make a Key

  1. Use a lock decoder/reader to decode the door lock for a working mechanical key.
  2. Use an appropriate automotive tryout-key set, such as Baxter Systems set 97 All Locks or Aero Lock T0-93.
  3. Remove a door or trunk cylinder and decode it; once the seven cuts are known, cut and verify the working key.
Professional service note: Programming requires compatible equipment and the vehicle PIN. Verify current programmer coverage and security-gateway requirements before service.
