Engine Immobilizer System: Registration

WARNING: This page is about a different car, the 2007 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.

HINT:

The key has 2 codes: the key code (immobilizer code), the wireless code (recognition code). Both of these codes need to be registered. Refer to the following pages for key code registration procedures and refer to page for the wireless code registration procedures.

  1. DESCRIPTION OF CODE REGISTRATION 
    1. When adding master keys and sub-keys (additional registration).
      1. Register the key code in the transponder key ECU.
        ECU REFERENCE CHART

        Target ECU See Procedure
        Transponder key ECU Procedure "A"
    2. When replacing the transponder key ECU (new registration).
      1. Register the key code in the transponder key ECU.
        ECU REFERENCE CHART

        Target ECU See Procedure
        Transponder key ECU Procedure "B"
      2. Register the ECU COMMUNICATION ID between the ECM and the transponder key ECU.
        ECU REFERENCE CHART

        Target ECU See Procedure
        ECM Procedure "C"
    3. When replacing the ECM.
      1. Register the ECU COMMUNICATION ID between the ECM and the transponder key ECU.
        ECU REFERENCE CHART

        Target ECU See Procedure
        Transponder key ECU Procedure "C"
  2. KEY REGISTRATION IN AUTOMATIC REGISTRATION (PROCEDURE "B") 
    1. When an ignition key is inserted into the ignition key cylinder, the key code registration is automatic. In this mode, a maximum of 4 key codes for 3 master keys and 1 sub-key can be registered. Any order of registration for the master keys and sub-key is fine because the transponder key ECU can distinguish between different types of keys.

      HINT:

      • When a new transponder key ECU is installed, key codes must be registered in the transponder key ECU.
      • New transponder key ECUs are automatically set to automatic key code registration mode.

      Automatic Key Code Registration (New Registration) 

      AUTOMATIC KEY CODE REGISTRATION REFERENCE CHART

      Procedure Security Indicator Condition
      1. START (Procedure "D") BLINKING
      HINT:
      Until the first key is inserted.
      2. Insert the ignition key cylinder. ON
      3. Registration begins.
      HINT:
      The registration is completed approx. 1 second after the key is inserted.      		 OFF
      HINT:
      Approx. 1 second.
      4. Remove the key. ON
      HINT:
      When the maximum number of key codes are registered, the security indicator remains OFF until the last key registered is removed. After it is removed, the security indicator starts blinking.
      5. Register another key?
      Yes: Go to procedure "D"
      No: Go to procedure "E"
      6. END (Procedure "E")

      HINT:

      • When no key is inserted in the key cylinder in automatic key code registration mode, the security indicator remains ON.
      • 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 below.

    2. Finish the automatic key code registration mode. The automatic key code registration mode can be forced to end when at least 1 key code for the master key has been registered.
      1. Turn the ignition switch ON and OFF 5 times within 10 seconds using the already registered master key.
  3. REGISTRATION OF ADDITIONAL KEY (PROCEDURE "A") 
    1. Register an additional key by the intelligent 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 key.
      NOTE: When the ignition key cylinder has been replaced, locking and unlocking doors is possible with the hew 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.
