Keys and doors
Immobilizer (if equipped)
The immobilizer system is designed to prevent an un-
authorized person from starting the engine. Only keys
registered with your vehicle’s immobilizer system can
be used to operate your vehicle. Even if an unregis-
tered key fits into the ignition switch and can be turned
to the “START” position, the engine will automatically
stop after several seconds.
Each immobilizer key contains a transponder in which
the key’s ID code is stored. When a key is inserted into
the ignition switch and turned to the “ON” position, the
transponder transmits the key’s ID code to the immo-
bilizer system’s receiver. If the transmitted ID code
matches the ID code registered in the immobilizer sys-
tem, the system allows the engine to be started. Since
the ID code is transmitted and acted upon almost in-
stantly, the immobilizer system does not impede nor-
mal starting of the engine.
If the engine fails to start, pull out the key once before
trying again. (Refer to the “Ignition switch” section
[chapter 3].)
