The Smart Key

Your Lexus vehicle was made with two “Smart Keys” and an aluminum key-number plate. Each Smart Key includes an electronic main key that has an integrated mechanical back-up key. The electronic key controls the remote-entry and theft-deterrent systems, enables the push-button start switch and controls the engine immobilizer.

The mechanical key can be removed from the electronic key and used to operate the driver’s door lock, the glove box lock and the trunk lock (if equipped).
