ENGINE IMMOBILISER SYSTEM
11L024−3
The engine immobiliser 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 at the center
cluster 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.
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.
