Engine Immobilizer System: Registration: Registration

WARNING: This page is about a different car, the 2011 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
  1. PERFORM NEW CODE REGISTRATION 
    1. When adding master keys and sub-keys (additional registration):
      1. Register the key code (immobilizer code) in the transponder key ECU assembly.
        Target ECU See procedure
        Transponder key ECU assembly Procedure "A"
    2. When replacing the transponder key ECU assembly (automatic registration):
      1. Register the key code (immobilizer code) in the transponder key ECU assembly.
        Target ECU See procedure
        Transponder key ECU assembly Procedure "B"
      2. Register the ECU COMMUNICATION ID between the ECM and the transponder key ECU assembly.
        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 assembly.
        Target ECU See procedure
        Transponder key ECU assembly Procedure "C"
    4. Erasure of key code:
      1. Erase the key code.
        Target ECU See procedure
        Transponder key ECU assembly Procedure "D"
  2. PERFORM KEY REGISTRATION 
    1. When an ignition key is inserted into the ignition cylinder, the key code (immobilizer 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-keys is fine because the transponder key ECU assembly can distinguish the types of keys.

      HINT: 

      • When a new transponder key ECU assembly is installed, key codes (immobilizer codes) must be registered with ignition keys.
      • New transponder key ECU assemblies are automatically set to automatic key code registration mode.
      AUTOMATIC KEY CODE REGISTRATION (PROCEDURE "B")

      Procedure Security Indicator Condition
      1. Start (Procedure "D") Blinking occurs until the first key is inserted.
      2. Insert the key into the ignition key cylinder. ON
      3. Registration begins.
      HINT: 
      The registration will be completed approximately 1 sec. after the key is inserted.      		 OFF
      HINT: 
      Approximately 1 sec.
      4. Remove the key. ON
      HINT: 
      When the maximum number of the key codes is 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: 

      • In automatic key code registration mode, when no key is inserted in the ignition key cylinder, 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 (immobilizer 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. PERFORM REGISTRATION OF ADDITIONAL KEY 
    1. Register additional keys by using Techstream.

      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.
      NOTE:

      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 a battery in the new master key's transmitter module fails, the original master key can be used to lock and unlock doors through the door key cylinder.

      ADDITIONAL REGISTRATION (PROCEDURE "A")

      Procedure Time
      (Completion of operation)      		 Security indicator Condition
      1. Start - The indicator will blink until the first key is inserted.
      2. Insert the already registered master key in the ignition key cylinder and turn the ignition switch on.
      3. Techstream operation:
      (1) Select Body Electrical
      (2) Select Immobilizer
      (3) Select Utility
      (4) Select Key Registration
      HINT:
