Upgrading to a flip key remote for your Mitsubishi can enhance convenience and modernize your car keys. If you’re looking to convert your standard or aftermarket key to a flip key, or need to program a new or used key fob, this guide provides a step-by-step approach based on community insights and practical experience. While specific models and years might have slight variations, these general instructions will walk you through the process.
Understanding the Key Components
Before you begin, it’s helpful to understand the components involved in your Mitsubishi car key system:
- Transponder Chip: This small chip is embedded within your key and is essential for starting your car. It communicates with your car’s Engine Control Unit (ECU) to verify the key’s authenticity.
- Key Fob: This is the remote control part of your key, responsible for locking/unlocking doors and sometimes opening the trunk. It communicates with the car’s Body Control Unit (BCU).
- Key Blade: The physical metal key that is cut to match your car’s ignition and door locks.
Transferring Your Transponder Chip to a Flip Key
If you have an existing aftermarket key and want to convert it to a flip key, you may be able to transfer the transponder chip. Here’s how:
- Open Your Existing Key: Carefully inspect your current key, especially aftermarket keys. Look for a seam or opening. Using a razor blade or similar tool, gently cut or pry open the key casing along the seam.
- Locate the Transponder Chip: Inside the key, you should find a small black chip, often housed in a white holder. This is your transponder chip.
- Remove the Transponder Chip: Carefully remove the transponder chip from its holder. Be gentle to avoid damaging it.
- Prepare Your Flip Key: Obtain a compatible flip key for your Mitsubishi. These are often available online.
- Insert the Transponder Chip: Open your flip key casing. You should find a small cavity, often near the flip mechanism button. Insert the transponder chip into this cavity.

Programming the Key Fob for Remote Functions
To enable remote locking/unlocking and trunk release with your flip key, you’ll need to program the key fob. This often involves using a used key fob and programming it to your car.
- Obtain a Used Key Fob: Search online marketplaces for a used Mitsubishi key with the fob intact. It’s often more cost-effective to use a used fob.
- Dismantle the Used Key: Once you have the used key, carefully dismantle it to remove the fob module from the key blade section.
- Install the Fob in Your Flip Key: Integrate the used key fob module into your new flip key. It should fit into a designated space within the flip key casing.
- Program the Fob Using the OBDII Port: Locate your car’s OBDII port, usually found under the dashboard on the driver’s side. The programming process typically involves using a paper clip to bridge specific pins in the OBDII port and cycling the ignition key. Consult your Mitsubishi owner’s manual or search online forums specific to your Mitsubishi model for the precise steps for key fob programming using the OBDII port and a paper clip. These steps can vary.

Getting Your Flip Key Blade Cut
Finally, you’ll need to have the key blade of your flip key cut to match your car’s ignition.
- Have the Key Blade Cut: Take your flip key and your original key to a locksmith or key cutting service. They can cut the new key blade to match your existing key, ensuring it works with your car’s locks and ignition.
Important Considerations:
- Key Blade Cutting First: It’s advisable to have the flip key blade cut before you dismantle your original working key. This ensures you always have a working key during the process.
- Transponder Bypass (Not Recommended): In emergency situations, you could technically bypass the transponder system by permanently affixing the transponder chip near the ignition switch. However, this is strongly discouraged as it compromises your car’s security system.
- Seek Specific Instructions: Always search for programming instructions specific to your exact Mitsubishi model and year. Online forums and owner’s manuals are valuable resources.
By following these steps, you can program a Mitsubishi car key remote and enjoy the benefits of a flip key. Remember to prioritize security and consult reliable resources for model-specific instructions.
