Upgrading to a flip key for your Mitsubishi can be a convenient and stylish improvement. If you’re looking to convert your standard aftermarket key or even add remote functionality, you might be surprised to learn you can do it yourself. This guide will walk you through the process of transferring your existing Mitsubishi key components into a flip key and programming the remote functions, potentially saving you a trip to the dealership and some money.
Understanding the Key Components: Transponder and Remote Fob
Before you begin, it’s helpful to understand the two main parts inside your car key that allow it to function:
- Transponder Chip: This is a small chip, often black and encased in plastic, that is programmed to your car’s immobilizer system. It’s essential for starting your Mitsubishi. Without a recognized transponder, your car won’t start, even if you have the correct key blade.
- Remote Fob (Optional): This is the electronic part with buttons to lock, unlock, and sometimes open the trunk. Not all keys have this, especially older or aftermarket keys. This communicates with your car’s Body Control Unit (BCU) to control door locking and other remote functions.
Step-by-Step Guide to Converting Your Mitsubishi Remote to a Flip Key
This process involves two main parts: transferring the transponder for starting the car and, if applicable, programming the remote fob for door locks.
Part 1: Transferring the Transponder Chip
- Prepare Your Keys: You’ll need your existing Mitsubishi key (especially if it starts the car) and your new flip key housing. It’s highly recommended to have the flip key blade cut before you disassemble your working key. You can get the key blade cut at a locksmith or some hardware stores.
- Open Your Existing Key: Carefully inspect your current key. Many aftermarket keys are designed to be opened. Look for a seam or a place where the two halves of the key casing join. Using a thin razor blade or a similar tool, gently pry along this seam to split the key open. Be patient and avoid damaging the plastic.
- Locate and Remove the Transponder Chip: Once open, carefully examine the inside of your key. You should find a small black chip, often housed in a white plastic holder. This is the transponder chip. Gently remove it. It’s usually not glued in place, but be careful not to damage it.
- Insert the Transponder into the Flip Key: Open your new flip key housing. Look for a small cavity, typically near the “flip” button mechanism. This cavity is designed to hold the transponder chip. Insert the transponder chip into this cavity. Ensure it fits snugly and is secure.
- Assemble the Flip Key: Close the flip key housing securely.
At this point, with the correctly cut key blade and the transferred transponder, your flip key should be able to start your Mitsubishi. Test it to confirm before proceeding to the remote fob programming.
Part 2: Programming the Remote Fob (If Applicable)
If you want to use the remote locking/unlocking functions with your flip key, and you have a separate remote fob from a used “cut” key (as mentioned in the original post), you’ll need to program the fob to your car.
-
Obtain a Compatible Remote Fob: The most straightforward method, as described, is to acquire a used Mitsubishi key with the remote fob intact. Dismantle this used key to extract the fob module from the diamond-shaped section.
-
Install the Fob in the Flip Key: Your flip key housing should have space to accommodate this fob module. Install it according to the flip key’s design.
-
Program the Fob to Your Mitsubishi: Mitsubishi key fob programming procedures can vary slightly by model and year. However, a common DIY method involves using a paper clip to bridge specific pins in the OBDII port (On-Board Diagnostics II port), which is usually located under the dashboard on the driver’s side. You will then typically follow a sequence of turning the ignition key on and off and pressing buttons on the fob to program it.
Important: Specific programming instructions are crucial and vary by Mitsubishi model. Search online forums or reliable automotive resources specific to your Mitsubishi model and year for detailed OBDII port programming steps. Incorrect procedures can lead to issues.
Conclusion: Enjoy Your Upgraded Mitsubishi Flip Key
By carefully following these steps, you can successfully convert your Mitsubishi key to a flip key and program the remote functions. This DIY approach can be a cost-effective way to upgrade your car key. Remember to prioritize having the key blade professionally cut before you start, and always double-check programming instructions specific to your Mitsubishi model to ensure a smooth and successful process.
