Smart Key System (Keyless Entry): Registration

HINT:

• ID code is the same as recognition codes for the wireless transmitter and the engine immobilizer function. Registering an ID code enables the smart key system, the wireless door lock control function and the engine immobilizer function to be operated.
• Code registration is needed when the certification ECU, ID code box, steering lock ECU or key is replaced with a new one.

1. Vehicles with the smart key system do not have a key slot. Therefore, hold the key close to the engine switch to register the key as shown in the illustration below.
