Title: THEFT DETERRENT / KEYLESS ENTRY: ENGINE IMMOBILISER SYSTEM(w/ Smart Key System): REGISTRATION; 2016 MY Sienna [12/2015 - 08/2016]

REGISTRATION

PROCEDURE

1. DESCRIPTION OF CODE REGISTRATION

HINT:

  • The ID codes are the same as recognition codes for the wireless transmitter and the engine immobiliser function. Registering an ID code enables the smart key system, the wireless door lock control function and the engine immobiliser function to be operated.
  • Code registration is necessary when the certification ECU, steering lock ECU, or key is replaced with a new one.
  • This vehicle does not have a key slot. Therefore, touch the logo of the key to the engine switch when registering the key, as shown in the illustration.

2. KEY REGISTRATION PROCEDURES WHEN ADDING OR REPLACING KEY OR WHEN KEY IS LOST

HINT:

  • The following procedures require the use of the Techstream:
    • - New key ID registration
    • - Additional key ID registration
    • - Key ID erasure
    • - All key ID erasure*1
  • A maximum of 7 keys can be registered.
