Key Id Register

All ignition keys can be registered with MUT-II scan tool or equivalent. Additional ignition keys can be registered with or without scan tool. If an ignition key is registered using scan tool, no registered ignition keys must be lost. Registration with scan tool is as follows:

  1. Connect MUT-II or equivalent scan tool to Data Link Connector (DLC). Turn ignition switch on.
  2. On scan tool at SYSTEM SELECT, press YES. Select IMMOBILIZER, press YES. Select SPECIAL FUNC, press YES. Select KEY ID REGISTER, press YES. If DTC 11 is stored, CAN'T EXECUTE will be displayed. Perform appropriate test procedure, see appropriate IMMOBILIZER SYSTEMS article in ACCESSORIES & EQUIPMENT.
    3. NOTE: NOTE: Four separate digits must be input to make up password.
  3. Input password. Use UP and DOWN keys to change current password digit to a value between 0 and 9. Use the LEFT and RIGHT keys to move to a different password digit. Press the YES key to accept password. If an incorrect password is input 5 times in a row, this screen is displayed and Immobilizer-ECU switches to unauthorized operation, start-prevention mode.
  4. Press YES key to start key ID registration.
  5. Scan tool will display COMPLETED when key ID registration is successful. If an error occurs during key ID registration, message CAN'T EXECUTE will be displayed. If key has already been registered, KEY ID HAS BEEN REGISTERED will be displayed.

To register an additional key, replace the ignition key with next key to be registered within 5 seconds and then press YES key. Key ID registration screen will be displayed, then register another key. A maximum of eight different keys can be registered. If key ID registration is complete, press the NO key.
  7. This completes the registration operation. Turn ignition switch to LOCK position and leave it off for about ten seconds.
