Encrypted Code Registration Using Bar Code No

When the ignition key that starts the engine is replaced due to the replacement of the ignition key set, the ignition key cylinder, etc., the bar code No. must be used to register encrypted codes.

CAUTION:
  • Do not register the ignition keys other than the ignition key that starts the engine. (When replacing by the door lock key cylinder of illustration < A> or the glove box lid lock cylinder of illustration, the engine cannot start if the encrypted code is registered with the bar code on the ignition key supplied simultaneously. If the ignition key using for each lock cylinder and starting engine is used as a common ignition key, replace by the key set of illustration < C>).

  • After the ignition key registration is finished, discard the bar code plate correctly at Mitsubishi dealer. The bar code plate has important information of the immobilizer system. Therefore, improper disposal of the bar code plate may decrease the security level.
  • When the transmitter is replaced, the transmitter must be registered after registering the encrypted code. For the registration of the transmitter, refer to HOW TO REGISTER SECRET CODE .
