How to Program Your 2010 Mitsubishi Lancer Key Fob

Lost your car key or need a spare for your 2010 Mitsubishi Lancer? Programming a new key fob for your vehicle might seem daunting, but it’s often achievable at home with the right instructions. This guide provides step-by-step methods to program your 2010 Mitsubishi Lancer Key Fob, covering both the key transponder and the remote control functions. Whether you’re dealing with a standard key or a remote head key, follow these procedures to get back on the road quickly and affordably.

Programming the Key Portion of Your 2010 Mitsubishi Lancer Key

Before you begin, ensure you have your new key cut by a locksmith or a qualified professional. This step is crucial as the key must physically match your Mitsubishi Lancer’s ignition cylinder. Once you have a correctly cut key, you can proceed with the programming steps below.

1. Insert an existing, working key into the ignition cylinder of your 2010 Mitsubishi Lancer.
2. Turn the ignition to the “ON” position (without starting the engine) and hold for 5 seconds. Then, turn it back to the “OFF” position and remove the working key.
3. Within 10 seconds of removing the first key, insert a second working key into the ignition and turn it to the “ON” position. You should observe the security light flashing twice. Turn the ignition back to “OFF” and remove the second working key.
4. Now, within 10 seconds, insert the new, unprogrammed key into the ignition and turn it to the “ON” position.
5. Wait for the security light to illuminate for approximately 3 seconds. This indicates that your new key has been successfully programmed to your 2010 Mitsubishi Lancer.
6. Turn the ignition to the “OFF” position and remove the newly programmed key. 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.
7. To exit the key programming mode, simply leave the ignition switched to the “ON” position for more than 30 seconds.

Programming the Remote Portion of Your 2010 Mitsubishi Lancer Key Fob

After programming the key portion, you’ll need to program the remote functionality of your 2010 Mitsubishi Lancer key fob. This process involves using the OBD-II data port in your vehicle.

1. Locate the OBD-II Data Port. In a 2010 Mitsubishi Lancer, this port is typically found under the driver’s side dashboard, usually to the right of the steering column.

2. Ensure your keys are out of the ignition and in the “OFF” position.

3. Identify terminals 1 and 4 on the OBD-II port. Using a suitable jumper wire, connect terminals 1 and 4. Keep the jumper wire connected throughout the remote programming procedure. It’s crucial to correctly identify terminals 1 and 4 for successful programming.

4. Within 10 seconds of connecting the jumper wire, press the Hazard Switch on your Mitsubishi Lancer 6 times. At this point, the doors should automatically lock and unlock once, signaling that the system has entered programming mode.

5. Take the remote you wish to program and press the “LOCK” button three times within 10 seconds. If the programming is successful, the doors will lock and unlock once again.

6. If you have additional remotes (including existing ones) to program, repeat step 5 for each remote within one minute. Each successful programming will be indicated by the doors locking and unlocking. You can program up to 4 remotes.

7. Once you’ve programmed all desired remotes, disconnect the jumper wire from the OBD-II port and remove any keys from the ignition. The remote programming process is now complete for your 2010 Mitsubishi Lancer key fob.

Programming New F.A.S.T. Keys (If Applicable)

If your 2010 Mitsubishi Lancer is equipped with a F.A.S.T.-key system and you have two valid, already programmed keys, you can follow these steps to program new F.A.S.T.-keys.

1. Remove the emergency key from the new F.A.S.T.-key.
2. While pressing the lock release buttons on the ignition switch, carefully remove the cover of the ignition switch.
3. Insert the emergency key into the ignition switch.
4. Take an already programmed F.A.S.T.-key and insert it into the emergency key (presumably they are designed to connect).
5. Turn the emergency key, along with the attached F.A.S.T.-key, to the “ON” position. Complete the following steps within 30 seconds.
6. Remove the programmed F.A.S.T.-key from the emergency key.
7. Using the first valid F.A.S.T.-key, press and hold the “UNLOCK” button for 4 to 10 seconds. While holding the “UNLOCK” button, press and release the “LOCK” button.
8. Release both the “LOCK” and then the “UNLOCK” buttons within 10 seconds of releasing the “LOCK” button in step 7. Complete the following steps within 30 seconds.
9. Using the second valid F.A.S.T.-key, repeat step 7: press and hold the “UNLOCK” button for 4 to 10 seconds, and while holding, press and release the “LOCK” button.
10. Release both the “LOCK” and then the “UNLOCK” buttons within 10 seconds of releasing the “LOCK” button in step 9. The immobilizer display should now blink on the information screen in your multi-information display. Complete the next step within 60 seconds.
11. Press the “LOCK” button twice on the new, blank F.A.S.T.-key. The immobilizer display should come on and remain illuminated for 30 seconds on the information screen.
12. This completes the registration process for your new F.A.S.T.-key.

Important Notes on Key Fob Programming:

• The indicator light on your key fob will illuminate each time a button is pressed, confirming button activation.
• The keyless entry system will not function if a key is left in the ignition switch.

By following these detailed instructions, you should be able to program your 2010 Mitsubishi Lancer key fob efficiently. Always double-check each step and ensure you are using compatible keys and remotes for your vehicle model. If you encounter difficulties, consulting a professional automotive locksmith or your Mitsubishi dealer is recommended.
