THEFT DETERRENT / KEYLESS ENTRY: ENGINE IMMOBILISER SYSTEM (w/ Smart Key System): REGISTRATION

1. DESCRIPTION OF CODE REGISTRATION

* 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
* A maximum of 7 keys can be registered.





3. PART REPLACEMENT AND KEY REGISTRATION PROCEDURES
