its not possible, once the ECM's on these vehicles see a security immobilizer it will always need to see one to run.

Agreed, the spare key is only intended to grant access to the vehicle but not start it. You will likely have to go to a dealer to order a new key and have it matched to the vehicles security system.


You can not unplug the immobilizer. T0y0ta07 is correct. A trip to the dealer is likely in your future or find your lost key.
