Introduction

In some cases, when customers fuel their vehicles at Mobil filling stations that use the Antenna-style Speedpass system, the customer may experience poor performance of the Smart Key system. Improvements in the system have been made to correct the following symptoms:

Remote Keyless Entry (conventional wireless transmitter) functions intermittently inoperative.
Keyless ignition function intermittently inoperative.

NOTE:

During the above conditions, the customer can always use the "Hard" key shank to unlock the doors and can start the ignition by inserting the key head into the ignition key slot.
This TSB addresses the above complaints only.
Some interference from strong electrical signals (including Speedpass) may still occur. Please refer to page 23 of the owner's manual for additional information.

NOTE:
- A maximum of 5 master key codes and 3 sub-key codes can be registered.
- Registration mode will end if each step is not completed within the specified time.
- When the key slot or the key cylinder set is replaced, remove the transmitter module from the original master key. Then install this transmitter module to a new key and use the new key as the master key. If necessary, use this master key to register other keys.
NOTE: When the key slot has been replaced, locking and unlocking doors is possible with the new master key's transmitter module (taken from the original master key). However, the new master key will not be able to lock and unlock doors through the door key cylinder. Keep the original master key.
