Smart Key System: Registration

  1. DESCRIPTION OF REGISTRATION: PROCEDURE 1 

    HINT:

    • Entry codes (wireless key codes) are the same as recognition codes for the wireless transmitter. Registering an entry key code enables both the smart key system and the wireless door lock control system to be operated.
    • Code registration is necessary when the certification ECU or key is replaced.
    1. Select a mode from the following:
      • New registration mode: New registration mode is used when the certification ECU is replaced with a new ECU.
      • Add mode: Add mode is used when a new key is added.
      • Communication mode: Communication mode is used to confirm the number of codes currently registered. Use the first screen of the key registration option.
      • Erasure mode: Erasure mode is used to erase all the key codes except for the code for the master key that is used during erasure mode. Use this mode when a key is lost.
    2. Perform code registration and code erasure according to the flowcharts (see PROCEDURE 2 and 3).

      HINT:

      • A total of 5 keys can be registered.
      • When registering a transmitter, do not have any other transmitters close to the transmitter being registered. The certification ECU may be unable to recognize which transmitter is sending signals.
  2. REGISTRATION OF NEW AND ADDITIONAL ENTRY KEY CODE: PROCEDURE 2 
    1. Register an entry key code using the intelligent tester.
      STATE SWITCHING CONDITION

      System state State switching condition Go to
      1. Start - -
      2. Vehicle should be in the following condition New registration mode.
      1. Master key is in key slot
      2. Power switch is ON (IG)
      		 3. Intelligent tester operation
      Add mode.
      Power switch is ON (IG)
      3. Intelligent tester operation
      1. Select PRIUS from menu.
      2. Select SMART KEY SYSTEM.
      3. Select ID UTILITY.
      4. Select SMART CODE REG.

      HINT:
      Perform operation according to prompts on tester screen and make sure that operation is finished without errors.      		 4. Check if it is new registration or additional registration
      4. Check if it is new registration or additional registration New registration mode (when certification ECU is new). 6. Key (transmitter) switch operation
      Add mode (when master key is already registered). 5. Master key (transmitter) switch operation
      5. Master key (transmitter) switch operation Press any one of the transmitter's switches.
      HINT:
      This operation should be performed with already registered master key.      		 6. Key (transmitter) switch operation
      6. Key (transmitter) switch operation (Within 30 seconds) HINT:
      • Perform this operation with key that will be newly registered. If no keys have been registered, register master key first in new registration mode.
      • When key code is registered, interactive communication is performed between key and certification ECU through indoor electrical key oscillator. Electrical key oscillator's reception is best in front seat area.
      • Interactive communication between the key and the ECU may take several seconds. The amount of time from switch operation to response is approximately 2 seconds.
      • In new registration mode, turn power switch OFF and then remove master key from key slot.

      1. Press the LOCK and UNLOCK switches on transmitter simultaneously.
      2. Within 3 seconds of the previous step, press any one of the switches.

      Wireless door lock buzzer sounds when registration is completed without errors.      		 7. Register other key codes or finish the registration
      7. Register other key codes or finish the registration Register other key codes.
      Continue registration.
      HINT:
      Select the next step on the tester screen.      		 5. Master key (transmitter) switch operation
      Finish the registration. End

      HINT:

      • A brief outline of procedures for key code registration is shown above. For more detailed information, please refer to the intelligent tester screen's instructions.
      • The number of currently registered codes can be checked on the first screen of the key code registration option.
  3. ERASURE OF ENTRY KEY CODE: PROCEDURE 3 
    1. Erase an entry key code using the intelligent tester.
      STATE SWITCHING CONDITION

      System state State switching condition Go to
      1. Start - -
      2. Vehicle should be in the following condition Power switch is ON (IG) 3. Intelligent tester operation
      3. Intelligent tester operation
      1. Select PRIUS from menu.
      2. Select SMART KEY SYSTEM.
      3. Select ID UTILITY.
      4. Select SMART CODE ERS.
      		 4. Master key (transmitter) switch operation
      4. Master key (transmitter) switch operation This operation should be performed with already registered master key.
      Press any one of transmitter's switches.      		 5. Intelligent tester operation
      5. Intelligent tester operation After above switch operation, operating tester according to tester screen instructions erases codes except codes of master key used in previous step. End
