Registration Procedure

WARNING: This page is about a different car, the 2002 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: In case of having lost all the already registered master keys, you are not able to do additional registration or deletion. Change the ECM and then must register the new key codes according to the following registration procedure of the automatic registration mode.
  1. Key registration in automatic registration mode  :
      NOTE:
      • This must be done when you install a new ECM.
      • The new ECM is on the automatic key code registration mode. The already fixed number of key codes for this ECM can be registered.
      • On this type of vehicle, up to 3 key codes can be registered.
      • In the automatic registration mode, the last key registered becomes sub-key.

      NOTE:
      • When a key is not inserted in the key cylinder on the automatic registration mode, the security indicator always lights on.
      • When the immobilizer system operates normally and the key is pulled out, the security indicator blinks.
      • When key code registration could not be performed on the automatic registration mode, code 2-1 is output from the security indicator and when inserting the already registered key, code 2-2 is output.
