Registration Not Using Scan Tool MB991958 (M.U.T.-III Sub Assembly) < USA Only >

WARNING: This page is about a different car, the 2008 Mitsubishi Lancer. However, it is still accessible from the selected car via links, so may be relevant.

When the keyless operation key is lost or additional keys are requested, the keyless operation key must be used to register key ID.

CAUTION: Two keyless operation keys that have been registered are needed.
  1. Turn the ignition switch to the "ON" position using the registered emergency key and keyless operation key.
  2. After turning the ignition switch to "ON," press and hold the UNLOCK button of the first registered keyless operation key for 4 to 10 seconds, and press the LOCK button during that time.
  3. Within 10 seconds after pressing the LOCK button in Step  2, release the LOCK button and then UNLOCK button. (Perform within 30 seconds after completion of Step  1.)
  4. Then, press and hold the UNLOCK button of the second registered keyless operation key for 4 to 10 seconds, and press the LOCK button during that time.
  5. Within 10 seconds after pressing the LOCK button in Step  4, release the LOCK button and then UNLOCK button. (Perform within 30 seconds after completion of Step  3.)
  6. The immobilizer indicator starts flashing, and the mode shifts to the keyless operation key additional registration mode.
  7. Check that the immobilizer indicator flashes, and press the LOCK button of unregistered keyless operation key twice. KOS starts registration communication with the keyless operation key.
  8. After the additional registration of keyless operation key is completed, the data is recorded to EEPROM, and when the data recording is completed, the immobilizer indicator flashes for 30 seconds.
  9. When a new keyless operation key is additionally registered, repeat Steps  1 to  8 after the ignition switch is turned to "LOCK" (OFF).
  10. The keyless operation key addition is terminated if any of the following conditions is met.
    • The additional registration of keyless operation key was completed.
    • The signal of LOCK button operation was received from the keyless operation key which was registered in Step  8.
    • Within 60 seconds after shift to the keyless operation key additional registration mode, the operation in Step  8 does not complete.
    • Before the registration communication with unregistered keyless operation key starts, the ignition switch was turned to "LOCK" (OFF).
    • The registration communication failed.
    • The recording to EEPROM failed.
