Is your 2010 Mitsubishi Galant Key Fob malfunctioning, or have you acquired a new key fob that needs programming? Programming your key fob can seem daunting, but for many 2010 Mitsubishi Galant models, it’s a process you can undertake yourself. This guide provides straightforward, step-by-step instructions to program both the key portion and the remote portion of your 2010 Mitsubishi Galant key fob.
Before you begin, it’s important to understand that there are two parts to programming your key fob: programming the transponder chip to start the engine and programming the remote buttons for keyless entry. Let’s tackle each part individually.
Programming the Key Portion (Transponder Chip) of Your 2010 Mitsubishi Galant Key Fob
This section outlines how to program the transponder chip, which is essential for starting your 2010 Mitsubishi Galant. You will need at least one existing, working key to perform this procedure. If you don’t have a working key, you will need to visit a locksmith or dealership for programming.
-
Key Preparation: Ensure your new key has been cut by a locksmith to match your 2010 Mitsubishi Galant’s ignition. This step is crucial before attempting to program the transponder.
-
Insert Working Key and Turn Ignition ON: Insert your existing, working key into the ignition cylinder. Turn the ignition to the “ON” position (without starting the engine). Keep it in the “ON” position for 5 seconds. Then, turn the ignition back to the “OFF” position and remove the key.
-
Insert Second Working Key and Turn Ignition ON: Within 10 seconds of removing the first key, insert a second working key (if you have one) into the ignition. Turn the ignition to the “ON” position. You should observe the security light on your dashboard flashing twice. After the flashes, turn the ignition back to the “OFF” position and remove the key.
-
Insert New Key and Turn Ignition ON: Within 10 seconds of removing the second working key, insert the new, unprogrammed key into the ignition cylinder. Turn the ignition to the “ON” position.
-
Wait for Security Light Confirmation: The security light should illuminate for approximately 3 seconds. This indicates that the new key has been successfully programmed to start your 2010 Mitsubishi Galant.
-
Test the New Key: Turn the ignition to the “OFF” position and remove the newly programmed key. Attempt to start your 2010 Mitsubishi Galant using this new key to confirm successful programming.
-
Program Additional Keys (Optional): If you have more new 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.
-
Exiting Programming Mode: If you do not need to program any more keys, simply leave the ignition switched to the “ON” position for more than 30 seconds to exit the programming mode.
Programming the Remote Portion (Keyless Entry) of Your 2010 Mitsubishi Galant Key Fob
Once the key portion is programmed to start your car, you’ll need to program the remote buttons for keyless entry. This process involves using the OBD-II data port in your 2010 Mitsubishi Galant.
- Locate the OBD-II Data Port: The OBD-II data port in a 2010 Mitsubishi Galant is typically located under the driver’s side dashboard. Look to the right of the steering column, underneath the dash, to find the port.

-
Prepare Jumper Wire and Keys: Ensure you have a suitable jumper wire to connect terminals on the OBD-II port. Insert your key into the ignition, leaving it in the “OFF” position.
-
Connect OBD-II Terminals 1 and 4: Carefully identify terminals 1 and 4 on the OBD-II port. Using your jumper wire, connect terminal 1 to terminal 4. Maintain this connection throughout the remote programming procedure. It is crucial to correctly identify terminals 1 and 4 to avoid any issues.
-
Press Hazard Switch Six Times: Within 10 seconds after connecting the jumper wire, press the hazard light switch rapidly six times. Upon successful entry into programming mode, the doors of your 2010 Mitsubishi Galant should automatically lock and unlock once. This indicates the system is ready for remote programming.
-
Press LOCK Button on Remote: Within 10 seconds of the doors locking and unlocking, press the “LOCK” button on the key fob you wish to program three times. Press it firmly each time within a 10-second window. If the programming is successful for that remote, the doors will lock and unlock once again.
-
Program Additional Remotes (Optional): If you have additional remotes to program, repeat step 5 for each remote. You can program up to 4 remotes, including any existing working remotes, within one minute. Remember to repeat step 5 for each remote within this timeframe. After each successful remote programming, the doors will lock and unlock once to confirm.
-
Disconnect Jumper Wire and Keys: Once you have programmed all desired remotes, disconnect the jumper wire from the OBD-II port. Remove the key from the ignition.
-
Test the Remote Functions: Test the “LOCK,” “UNLOCK,” and “PANIC” buttons on each programmed remote to ensure they are working correctly with your 2010 Mitsubishi Galant’s keyless entry system.
By following these steps, you should be able to successfully program your 2010 Mitsubishi Galant key fob for both starting the vehicle and utilizing the keyless entry functions. If you encounter any difficulties or are unsure about any step, consulting a professional locksmith or your Mitsubishi dealership is always recommended.
