REGISTRATION PROCEDURE
1. KEY REGISTRATION IN AUTOMATIC REGISTRATION MODE
(a) Registration of a new transponder key.
HINT:

This must be done when you have installed a new ECM.

The new ECM is in the automatic key code registration mode. The already fixed number of key codes
for this ECM can be registered.
On this type of vehicle, up to 4 key codes can be registered.

In the automatic registration mode, the last key registered becomes sub±key.

HINT:

When a key is not inserted in the key cylinder in the automatic registration mode, the security indicator
always lights on.

When the immobiliser system operations normally and the key is pull out, the security indicator blinks.

When key code registration could not be performed in the automatic registration mode, code 2±1 is
output from the security indicator and when inserting the already registered key, code 2±2 is output.
(b) Automatic registration mode completion
If completing the mode forcibly when more than 1 key code have been registered in the automatic reg-
istration mode, perform the following procedures.
After 1 more key code have been registered with master key, perform step (1) or (2) without pulling
the key out or inserting the already registered key.
(1) Depress and release brake pedal 5 times or more within 15sec.
(2) With the TOYOTA hand±held tester, require automatic registration mode completion.

Will you register the
next key?
No Ye s
Insert already registered master key in the key
cylinder
Depress and release the acceleration pedal 5
times.
Depress and release the brake pedal 6 times,
and remove the master key.
Insert key to be registered in key cylinder.
Depress and release the acceleration pedal 1
time. (Security indicator blinks)
The registration mode completes when pulling
out the key within 10sec. and the brake pedal is
depressed or after indicator is off 10 sec. pass. Within 10 sec.Within 15 sec.

2. REGISTRATION OF ADDITIONAL MASTER KEY
There are 2 ways for registration of additional master key, one is depressing brake pedal and acceleration
pedal and the other is using TOYOTA hand±held tester.
HINT:

It is possible to register up to 7 master key codes including the already registered key code.

When any operation time described below is over, registration mode completes.

When the next procedure is performed while the timer is working, the timer completes counting time,
then next timer starts.
(1) Depressing brake pedal and acceleration pedal:

Will you register the
next key?
Insert already registered master key in the key cylinder.
Listing TOYOTA hand±held tester select master key reg-
istration.
Remove the master key.
Insert key to be registered in key cylinder.
(Security indicator blinks)
After 60 sec., additional master key is registered.
(Security indicator OFF)
The registration mode completes when pulling out the key
within 10sec. and the brake pedal is depressed or after in-
dicator is off 10 sec. pass.No Ye s Within
