Toyota 4Runner: Registration

REGISTRATION

PROCEDURE

1. DESCRIPTION OF CODE REGISTRATION

The key has 2 codes: the key code (immobiliser code) and the wireless code (recognition code). Both of these codes need to be registered. For wireless code registration procedures, refer to the following procedures (See page ). For key code registration procedures, refer
to the procedures below.

The key code is needed when the transponder key ECU, ECM or key is replaced with a new one.

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 ID registration
    • - Additional key ID registration
    • - Key ID erasure
  • A maximum of 8 key codes for 5 master keys and 3 sub-key can be registered.

Customer Request/Condition

Registration Procedure Condition

Procedure

Refer to

Registering additional key

Customer must bring at least 1 master key

1. Register additional keys as necessary (additional key ID registration)

PROCEDURE "B"

PROCEDURE "E"

4. KEY REGISTRATION PROCEDURES

(a) PROCEDURE "A"

New key code registration

HINT:

  • This mode operates normally when no key codes are registered in the transponder key ECU.
  • When a new transponder key ECU is installed, key codes must be registered in the transponder key ECU.
  • In this mode, a maximum of 3 key codes for 2 master keys and 1 sub-key can be registered. The master keys and sub-key can be registered in any order because the transponder key ECU 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.

Procedure

Security Indicator Light Condition

1. Start registration

Security indicator light is blinking

2. Insert one of master keys into ignition key cylinder

Security indicator light turns on

3. Enter the following menus:

(1) Body Electrical

(2) Immobiliser

(3) Utility

(4) Key Registration

HINT:

After above operation, proceed to next step in accordance with prompts on screen

Security indicator light turns off for 1 sec. and then turns on

4. Remove key

Security indicator light turns on

HINT:

When maximum number of key codes is registered, security indicator light remains off until last key registered is removed. After it is removed, security indicator light starts blinking.

5. Register another key?

YES: Go to step 6

NO: Go to step 7

HINT:

Key codes for maximum of 2 master keys and 1 sub-key can be registered

6. Insert another key into ignition key cylinder. Then go to step 4.

Security indicator light turns off for 1 sec. and then turns on

7. End of registration

(1) End new key code registration mode (when not using the Techstream)

HINT:

Automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for a master key is registered.

  1. Turn the ignition switch to ON and LOCK 5 times within 10 seconds using a master key that is already registered.

(2) End new key code registration mode (when using the Techstream)

HINT:

Automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for a master key is registered.

  1. Insert the key into the ignition key cylinder and turn the Techstream on.
  2. Follow the instructions on the Techstream screen to end new key code registration mode.

    HINT:

    • When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
    • If new key code registration fails, code 2-1 is output by the security indicator light. Trying to reregister an already registered key causes code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 is output by the security indicator light.

(b) PROCEDURE "B"

Additional key code registration

HINT:

  • At least one key code must be registered in the transponder key ECU in order for this mode to operate normally.
  • In this mode, a maximum of 5 master key codes and 3 sub-key codes can be registered.
  • This mode ends if each step is not completed within the specified time.
  • When the ignition key cylinder or the ignition 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 only the ignition key cylinder is replaced, the new key cannot be used to lock or unlock doors. Therefore, keep the original key for locking and unlocking doors in order to avoid being locked out of the vehicle if the transmitter battery becomes depleted.
