PRE±CHECK
Make the vehicle in the initialized condition:
The initialized condition is the condition when the following conditions are satisfied.
(1) Key plate has not been inserted in the ignition key cylinder.
(2) All the doors are closed. (Door warning light is OFF.)
(3) All the doors are locked.
(4) Wireless door lock control switch (Buzzer switch) is ON.
Under the standard operation, when repeating UNLOCK and LOCK switch 3 times or more alternately, check the
UNLOCK±LOCK operation from 3rd time onward.

Following procedures are standard operation.
(1) Keep about 1 M away to the right direction from the outside handle of a driver's seat.
(2) Face the transmitter toward the vehicle and press one of transmitter switches for about 1 sec.


As of the security function, even the wireless function is normal, there may be the case that only UNLOCK opera-
tion will not work.

As of the body customize function, if ºoperation twiceº has been set using LEXUS hand±held tester, only driver's
seat is unlocked by unlock operation performed once.
Normal


Operative distance may differ according to
an operator, the way of holding the transmitter
or position.

Because weak electric wave is used, when
there is strong wave or noise in the used
frequency ,operation distance might be
shortened.
No Yes
Only wireless function (Remote control) will not operate.
(If a new transmitter or a transmitter of the same type that works properly with the vehicle is not available.)
Check when pressing UNLOCK switch
and LOCK switch under standard
operation, that the transmitter LED
lights up once more.
