Mitsubishi Smart Key (Fast System): key programming and KOS remote synchronization

A specific procedure for Mitsubishi vehicles with a smart key (fast system), i.e. the button remote with a metal blade inside it. It explains how to bring the smart key into contact with the ignition lock so it can be registered, and how to then program the KOS remote.

Procedure

1. Pull out the metal blade held inside the smart key. You need a blade that fits properly into the vehicle's ignition lock.
2. There is a small black cover on the ignition lock: remove it and fit the key's metal blade in its place.
3. Turn the ignition ON and hold the smart key on top of the blade fitted in the lock: this is how the key is read by the system.
4. Connect the AVDI to the OBDII socket and open the key programming function in "Special Functions".
5. Before starting the registration, press the "Help" button to confirm you are using the correct PIN code.
6. Start the programming: if the PIN is correct the first key is registered and the software tells you the procedure was successful.
7. Repeat the same sequence to register the further keys that have to stay working on the vehicle.
8. With the keys done, move on to the KOS remote: with the ignition ON press the "Synchronize Remote Control" button.
9. The software asks you to press the remote's <LOCK> button twice. If all is well you hear a confirmation BEEP.
10. Program the second remote the same way: press the <LOCK> button twice when prompted.
11. Finish the job with a practical check: start the vehicle and test the remotes by pressing the <LOCK> and <UNLOCK> buttons.
