    CAUTION:
    • Special caution should be taken for handling each component as they are precise electronic components.
    • When replacing the transmitter, it is necessary to register the identification code as it is a single part.
    • If the vehicle is equipped with the immobilizer, it is necessary to register the immobilizer when replacing the transmitter.
    1. Using a fine cross slot screwdriver, remove the using a screw and cover.
    2. Remove the transmitter.
      CAUTION: Do not pry out the cover forcibly.

      HINT:

  2. INSTALL TRANSMITTER SUB-ASSY MODULE SET DOOR CONTROL 
    1. Place the transmitter on the key plate and install the cover on it.
    2. Tighten the screw using a fine cross slot screwdriver.
    3. After replacing the transmitter, register the identification code.
  3. REGISTER RECOGNITION CODE 

    HINT:

    • The add mode is used to retain already registered codes while registering new recognition codes. This mode is used when adding a transmitter. If the number of registered codes exceeds 4, previously registered codes will be correspondingly erased in order, starting from the first registered code.
    • The rewrite mode is used to erase all the previously registered codes and register only new recognition codes. This mode is used when exchanging the transmitter or the door control receiver for new one.
    • The prohibition mode is used to erase all the registered codes and cancel the wireless door lock function. Use this mode when the transmitter is lost.
    • The confirmation mode is used to confirm how many recognition codes have already been registered before an additional registration of a recognition code.
