Most remotes can be self-programmed. If these procedures do not work, you must have your remote programmed by a professional automotive locksmith or dealership.

Procedure #1 (97-98 Mitsubishi Diamante, 97 Mitsubishi Galant)
Obtain all remote transmitters for this vehicle. This procedure's a little more complicated than others, we recommend having someone help you perform this procedure. We have found it easier to have one person manage the jumper wire while the second person performs the procedure.
1. Locate the Data Link Connector (DLC). It will be under the dash on the drivers side. You may need to lay on the floor and look up to easily access it. Use the diagram above to identify ports 1 and 4. Notice that the DLC connector is tapered. You can use this to help identify the proper ports. Be sure there's metal contact pins in ports 1 and 4.
2. Insert key into the ignition and leave in the OFF position.
3. Using a suitable jumper wire, jump pin 1 to pin 4. Jump means to make a connection between the two pins using any metal wire. A paperclip bent in the shape of a "U" usually works perfect. Be certain the jumper wire makes contact with the pins in ports 1 and 4. Once the jumper wire is installed it needs to remain there throughout this procedure until instructed to remove.
4. Within ten seconds of connecting the jumper wire, turn the ignition switch to ACC then back to OFF. (ACC is the position when you turn the key back toward you, OFF is the position where you can remove your key). The doors will automatically lock and unlock once indicating the vehicle is in programming mode.
5. Now press the LOCK or UNLOCK button on the first remote to be programmed THREE TIMES within ten seconds. The doors will automatically lock and unlock once indicating the vehicle has programmed that remote.
6. If you have additional remotes to program, repeat step 5. within one minute.
7. Once all remotes are programmed remove jumper. Test all remotes to ensure proper programming.
Procedure #2 (96-98 Eagle Talon)
Obtain all remote transmitters for this vehicle.
1. Insert key into ignition. Do not turn ignition switch, leave in OFF position.
2. Locate the Data Link Connector (DLC). It will be under the dash on the drivers side. Use the diagram above to identify pins 1 and 4. Notice that the DLC connector is tapered. You can use this to help identify the proper pins. Using a suitable jumper wire, jump pin 1 to pin 4. Ensure that there are metal connector ends in the cavities that are referenced in this procedure. Once the jumper wire is installed it needs to remain there throughout this process until instructed to remove.
3. Close all vehicle doors. Turn the ignition switch to the ACC position and then back to OFF. This must be done within 10 seconds of installing the jumper wire. If all is done properly then the locks will automatically cycle Lock and Unlock. This means the vehicle is in programming mode and you are ready to program your remotes.
4. Depress either the LOCK or UNLOCK button on the first remote to be programmed three times within ten seconds. If the remote is successfully programmed then the locks will again automatically cycle Lock to Unlock.
5. To program an additional remote repeat step 4 and after remote is programmed you should see the door locks cycle automatically from Lock to Unlock. This step must be completed within one minute of programming the first remote.
6. Disconnect jumper wire and remove key from ignition at this point as the programming is done. Test all remotes to ensure proper programming.
