KEYS AND DOORS
13
11E042
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 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. If you make your own duplicate key, you will not be
able to cancel the system or start the engine.
For vehicles sold in U.S.A.
