Smart Key Entry System (Keyless Entry) (Diagnostics): Registration

DESCRIPTION OF REGISTRATION
HINT:
- Smart key codes are the same as recognition codes for the wireless transmitter. Registering a smart key code enables both the smart entry system and the wireless door lock control system to be operated.

    Used when the smart key ECU is replaced with a new ECU.
  - Add mode:
    Used when a new key is added.

    After using the erase mode to erase all smart key codes previously registered, use the re-registration mode to reenter them.
  - Erasure mode:
    Used to erase all the key codes except for the code of the master key that is used during erasure mode. Use this mode when a key is lost.
  - Reset mode:
    Used to reset all the key codes (including master key). Use this mode when all keys are lost.
2. Perform the code registration and the code erasure according to the flowcharts (See STEP 2 and 3).
  HINT:
  
  Up to 5 master keys can be registered in the smart key ECU.
