Registration Procedure

NOTE:

In case of having lost all the already registered master keys, you are not able to do additional registration or deletion. This requires changing the engine and ECT ECU and then registering 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 Engine and ECT ECU.
      • The new Engine and ECT ECU is on the automatic key code registration mode. The already fixed number of key codes for this Engine and ECT ECU 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.
