ENGINE IMMOBILIZER SYSTEM
The engine immobilizer system is a theft prevention
system. When you insert the key in the ignition switch, the
transponder chip in the key’s head transmits an electronic
code to the vehicle. The engine will start only when the
electronic code in the chip corresponds to the registered
ID code for the vehicle.
The system is automatically set when the key is removed from
the ignition switch. At this time, the security indicator light
flashes. When you insert the key in the ignition switch, the
security indicator light goes out and the system is canceled
automatically, which enables the engine to start.
The transponder chip of the flat key is in its key case. You can
cancel the engine immobilizer system using the flat key. (For
details, see “Flat key” on page 9.) For your Lexus dealer to make you a new key with built
−in
transponder chip, your dealer will need your key number and
master key. However, there is a limit to the number of
additional keys your Lexus dealer can make for you.
If you make your own duplicate key, you will not be able to
cancel the system or start the engine.
