Customer Request/Condition

Registration Procedure Condition

Procedure

Refer to

Registering additional door control transmitter assembly

Customer must bring at least 1 door control transmitter assembly.

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 master key codes can be registered. The master keys can be registered in any order because the transponder key ECU assembly can distinguish between different types of door control transmitter assemblies.
  • 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 door control transmitter assembly is inserted

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

Blinking

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 door control transmitter assembly 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, ON for 0.5 seconds and then OFF

6. Remove the door control transmitter assembly.

Blinking

7. End

HINT:

  • When the immobiliser system is operating normally and the door control transmitter assembly is pulled out, the security indicator light blinks continuously.
  • If new key code registration fails, code 2-1 will be output through the security indicator light. Trying to re-register an already registered door control transmitter assembly will cause code 2-2 to be output when the door control transmitter assembly 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:

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 re-registered.
  • Additional key code registration will end if any step is not completed within the specified time.
  • If the ignition key cylinder or the key cylinder set is replaced, remove the transmitter module from the original master key. Then install the transmitter module to a new key and use the new key as the master key. If necessary, use this master key to register other door control transmitter assemblies.

NOTICE:

When the ignition key cylinder has been replaced, locking and unlocking of 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.
