PROCEDURE

1. DESCRIPTION OF CODE REGISTRATION

(a) w/ Wireless Door Lock Control System:

The key has 2 codes: the key code (immobiliser code) and the wireless code. Both of these codes need to be registered. For the wireless code registration procedures, refer to Wireless Door Lock Control System (w/o Smart Key System) (See page 2. KEY REGISTRATION PROCEDURES WHEN ADDING OR REPLACING KEY OR WHEN KEY IS LOST ).

2. KEY REGISTRATION PROCEDURES WHEN ADDING OR REPLACING KEY OR WHEN KEY IS LOST

HINT:

  • The following procedures require the use of the Techstream:
    • - New key code registration
    • - Additional key code registration
    • - Key code erasure
  • A maximum of 5 key codes can be registered.

Customer Request/Condition

Registration Procedure Condition

PROCEDURE "F"

4. KEY REGISTRATION (PROCEDURE "A")

(a) New key code registration (Procedure "A"):

NOTICE:

Make sure that no key codes are registered in the transponder key ECU assembly.

HINT:

  • In this mode, a maximum of 2 key codes for 2 master keys can be registered. The master keys can be registered in any order because the transponder key ECU assembly can distinguish between different types of keys.
  • New key codes must be registered with the battery connected. The ignition switch can be either ON or off.
  • When a new transponder key ECU assembly is installed, key codes must be registered in the transponder key ECU assembly.
Automatic Key Code Registration (New Registration)

Procedure

Security Indicator Light Condition

1. Start

Blinking

HINT:

Until first key is inserted

2. Insert the master key into the ignition key cylinder.

On

3. Techstream operation

Enter the following menus: Body Electrical / Immobiliser / Utility / Key Registration

HINT:

After completing the above operation, proceed to the next step in accordance with the prompts on the Techstream screen.

Off for 1 second and then on

4. Remove the key and then select Next on the Techstream.

On

5. Insert the master key to be registered and then select Next on the Techstream.

Off for 1 second and then on for 0.5 seconds and then off

6. Remove the key.

Blinking

7. End

HINT:

  • When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
  • If the new key code registration fails, code 2-1 will be output through the security indicator light. 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 maximum limit, code 2-3 will be output through the security indicator light. The output details are shown below.
(b) End automatic key code registration mode:

(b) End automatic key code registration mode:

Automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) has been registered as the master key.

HINT:

Follow the instruction on the Techstream screen to end new key code registration mode.

5. KEY REGISTRATION (PROCEDURE "B")

(a) Additional registration (Procedure "B"):

HINT:

  • A maximum of 5 master key codes can be registered.
  • Registration mode will end if any 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 transmitter module (removed 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 battery in the new master key transmitter module fails, the original master key can be used to lock and unlock doors through the door key cylinder.
