Lost your key fob or need to program a new one for your 2012 Mitsubishi Galant? Don’t worry, you might be able to do it yourself! This guide provides straightforward, step-by-step instructions to program your 2012 Mitsubishi Galant Key Fob, also known as your keyless entry remote or smart key. We’ll cover both programming the key portion and the remote portion so you can get back on the road quickly.
Programming the Key Portion of Your 2012 Mitsubishi Galant Key Fob
Before starting, remember that you’ll need to have the new key cut by a locksmith to match your ignition. This procedure focuses on programming the transponder chip within the key, allowing it to start your car.
- Insert a Working Key: Begin by inserting an existing, functional key into the ignition cylinder. This is crucial as the system needs to recognize a valid key to initiate the programming sequence.
- Turn Ignition ON and OFF: Turn the ignition to the “ON” position (without starting the engine) and hold it for 5 seconds. Then, turn the ignition back to “OFF” and remove the key.
- Insert Second Working Key: Within 10 seconds of removing the first key, insert a second working key into the ignition and turn it to the “ON” position. Watch for the security light on your dashboard; it will flash twice to confirm the system has recognized the second key. Turn the ignition back to “OFF” and remove this second key.
- Insert the New Key: Now, within 10 seconds, insert the new, unprogrammed key into the ignition and turn it to the “ON” position.
- Wait for Security Light: Keep the ignition in the “ON” position. The security light should illuminate for approximately 3 seconds. This indicates that your new 2012 Mitsubishi Galant key has been successfully programmed to start the vehicle.
- Test and Program Additional Keys (Optional): Turn the ignition to “OFF” and remove the newly programmed key. Test the key to ensure it starts your Galant. If you have additional keys to program, repeat steps 4 and 5. Remember, all new keys must be programmed within 30 seconds of the security light flashing twice in step 3.
- Exit Programming Mode: If you don’t need to program more keys, simply leave the ignition switched to the “ON” position for more than 30 seconds. This will automatically exit the programming mode.
Programming the Remote Portion of Your 2012 Mitsubishi Galant Key Fob
Once the key portion is programmed, you’ll need to program the remote functionality to lock and unlock your doors remotely. This involves using the OBD-II data port in your Mitsubishi Galant.
-
Locate the OBD-II Data Port: Find the Data Port, which is typically located under the driver’s side dashboard, usually to the right of the steering column.

-
Ignition OFF and Prepare Jumper Wire: Ensure your keys are out of the ignition and the ignition is in the “OFF” position. You will need a jumper wire to connect specific terminals in the Data Port.
-
Connect Terminals 1 and 4: Identify terminals 1 and 4 on your OBD-II Data Port. Carefully connect these two terminals using your jumper wire. Keep the jumper wire connected throughout the remote programming process. Double-check your vehicle’s manual or a reliable wiring diagram to confirm the correct terminals if you are unsure.
-
Press Hazard Switch: Within 10 seconds of connecting the jumper wire, press the Hazard Switch (hazard lights button) 6 times. If done correctly, the doors will automatically lock and unlock once. This indicates that your 2012 Mitsubishi Galant has entered the key fob programming mode for the remote.
-
Program the Remote: Press the “LOCK” button on the key fob you want to program three times within 10 seconds. Upon successful programming of the remote, the doors will lock and unlock once again, confirming the signal has been received and the remote is now programmed.
-
Program Additional Remotes (Optional): If you have more remotes to program, repeat step 5 for each additional remote, up to a maximum of 4 remotes (including any previously programmed remotes). Remember to program each remote within one minute of the previous one. The doors will lock and unlock after each successful remote programming.
-
Disconnect and Test: Once you have programmed all desired remotes, disconnect the jumper wire from the Data Port and remove any keys from the ignition. Test each remote to ensure it correctly locks and unlocks your 2012 Mitsubishi Galant.
By following these steps, you should be able to program your 2012 Mitsubishi Galant key fob yourself. If you encounter any difficulties, it’s always recommended to consult a professional locksmith or your Mitsubishi dealership for assistance.
