Upgrading to a flip key for your Mitsubishi can offer both convenience and a modern touch. Many Mitsubishi owners are looking to enhance their vehicle’s key system, and converting to a flip key remote is a popular DIY project. This guide will walk you through the process of converting your standard Mitsubishi key to a flip key and programming the remote functions, drawing upon community experiences and expert insights.
Understanding the components is crucial before you begin. Your Mitsubishi key system typically involves two main parts: the transponder chip and the remote fob. The transponder chip is a small, often black, component embedded within the key. It’s programmed to your car’s Engine Control Unit (ECU) and is essential for starting the vehicle. Separately, the remote fob controls door locking, unlocking, and sometimes trunk release functions. This fob communicates with your car’s Body Control Unit (BCU).
To start the conversion, you’ll need a few items. Firstly, acquire a compatible flip key shell designed for Mitsubishi vehicles. These are readily available online. Secondly, if you want to retain remote functionality, you’ll need a used Mitsubishi key fob. Online marketplaces are good sources for these. Ensure the used fob is intact and includes the internal circuit board.
The first step in the physical conversion is carefully opening your existing Mitsubishi key. Using a razor blade or a similar tool, gently cut along the seam of your original key. Inside, you’ll find the transponder chip, usually housed in a white holder. Carefully remove this chip. Next, take your new flip key shell and locate the cavity designed to house the transponder. It’s typically near the flip mechanism button. Insert the transponder chip from your old key into this cavity in the flip key.

For the key blade, you have two options. You can either have the new flip key blade cut to match your original key at a locksmith or key cutting service. It’s advisable to get the flip key blade cut before disassembling your original key, if possible. Alternatively, some flip key kits allow you to transfer your original key blade if it’s compatible. If you didn’t get the flip key blade cut beforehand, remember that to simply start your car, only a cut key blade and the transponder chip are needed near the ignition.
Now, for programming the remote functions, you’ll need the used Mitsubishi key fob you acquired. Disassemble the used key to extract the fob circuit board. Integrate this fob circuit board into your flip key shell, ensuring it fits properly. With the physical key assembled, you can now program the remote to your Mitsubishi.
Programming the Mitsubishi key fob typically involves using the OBDII port in your car and a simple paper clip. The exact procedure can vary slightly depending on your Mitsubishi model and year. However, a common method involves locating the OBDII port (usually under the dashboard on the driver’s side). You’ll need to use a paper clip to bridge specific pins in the OBDII port while turning the ignition on and off in a specific sequence. This process puts your car into programming mode, allowing it to learn the new remote fob signal. Detailed instructions for your specific Mitsubishi model can usually be found in online forums or specific vehicle repair guides. Search for “Mitsubishi key fob programming OBDII paper clip” along with your car model for more precise steps.
Once in programming mode, pressing the lock or unlock button on your flip key fob should signal the car to recognize the new remote. You may need to repeat this process for all remote functions (lock, unlock, trunk). After successful programming, test all buttons to ensure they are working correctly.
Converting to a flip key and programming it yourself can be a rewarding experience. It enhances the functionality and look of your Mitsubishi key while potentially saving money compared to dealership programming services. Always double-check model-specific instructions and exercise caution when disassembling keys and working with your vehicle’s electronics.
