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. The indicator light will start flashing to show the system is set.
If any of the following indicator conditions occurs, contact your Toyota dealer.
• The indicator light stays on.
• The indicator light does not start flashing when the key is removed from the ignition switch.
• The indicator light flashes inconsistently.
Inserting the registered key in the ignition switch automatically cancels the system, which enables the engine to start. The indicator light will go off.
For your Toyota dealer to make you a new key with a 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 Toyota 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.
Do not modify, remove or disassemble the engine immobilizer system. If any unauthorized changes or modifications are made, proper operation of the system cannot be guaranteed.
