3. REGISTRATION OF ADDITIONAL KEY (ADDITIONAL REGISTRATION)
(a) Register an additional key by using the hand-held tester.
HINT:

A maximum of 5 master key codes and 3 sub-key codes can be registered.

Registration mode will end if each step is not completed within the specified time.

When the ignition cylinder or the key cylinder set is replaced, remove the transmitter module from the
original master key. Then install this transmitter module to a new key and use the new key as the master
key. If necessary, use this master key to register other keys.
NOTICE:
When the ignition key cylinder has been replaced, locking and unlocking doors is possible with the
new master key's transmitter module (taken from the original master key). However, the new master
key will not be able to lock and unlock doors through the door key cylinder. Keep the original master
key. If the new master key's transmitter module's battery fails, the original master key can be used
to lock and unlock doors through the door key cylinder.

Remove the master key.
Insert the already registered master key in the ignition key cylinder and
turn the ignition switch ON.
1. Select HIGHLANDER from the menu.
2. Select IMMOBILISER.

HINT:

A brief outline of procedures for key code registration is shown on the previous page. For more detailed
information, please refer to the hand-held tester screen's instructions.

When the immobilizer system is operating normally and the key is pulled out, the security indicator
blinks continuously.

If the key code registration has failed in automatic key code registration mode, code 2-1 will be output
from the security indicator. Trying to re-register an already registered key will cause code 2-2 to be
output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 will
be output from the security indicator. The output details are shown in step 2 (new registration).

Remove the master key.
Insert the already registered master key in the ignition key cylinder
