Are you looking to modernize your 2006 Mitsubishi Eclipse key? Many owners of this popular sports car are seeking to upgrade from the standard key to a more convenient and stylish flip key. This guide will walk you through the process of converting your existing key fob to a flip key, drawing upon the experiences of fellow enthusiasts.
Understanding the Conversion Process
The original key for your 2006 Mitsubishi Eclipse likely consists of two main components: the key blade itself and a transponder chip. The transponder is a small, but crucial, component that communicates with your car’s immobilizer system, allowing the engine to start. For remote locking and unlocking functionalities, a separate key fob is needed. The goal of this conversion is to integrate these components into a modern flip key housing.
Retrieving the Transponder Chip
If you have an aftermarket key, as mentioned in the original post, you might be able to salvage the transponder chip from it. Carefully disassemble your existing aftermarket key. By gently cutting along the seam of the key housing, you should be able to access the internal components. Locate the transponder chip – it’s often described as a small black box or chip housed within a white holder. This chip is programmed to your car’s Engine Control Unit (ECU) and is essential for starting the vehicle. Carefully remove this transponder chip.
Preparing the Flip Key
Purchase a compatible flip key casing designed for Mitsubishi vehicles. These are readily available online. These flip key housings typically have a cavity designed to hold a transponder chip. Locate this cavity, usually near the flip mechanism button, and insert the transponder chip you removed from your original key.
Key Blade Cutting
To ensure the flip key can physically start your car, you’ll need to have the key blade cut to match your original key. It is highly recommended to get the flip key blade cut before disassembling your existing working key. A locksmith or key cutting service can accurately duplicate your key blade onto the new flip key blade blank. If, for any reason, you’ve already disassembled your original key, remember that only a cut key blade and the transponder chip are necessary to start the engine.
Adding Remote Functionality (Optional)
For remote locking, unlocking, and trunk release functions, you’ll need to integrate a key fob into your flip key. The most straightforward method, as suggested, is to acquire a used, uncut Mitsubishi key with the fob intact from online marketplaces. Dismantle this used key to extract the fob module from its diamond-shaped housing. Carefully install this fob module into the designated space within your flip key casing.
Programming the Fob: The used fob will not automatically work with your car. You will need to program it to your 2006 Mitsubishi Eclipse’s Body Control Unit (BCU). Instructions for programming the fob using a paper clip and the OBDII port are often available online and in forums dedicated to Mitsubishi Eclipse modifications. Search for “Mitsubishi key fob programming paper clip OBDII” for specific steps.
Important Considerations and Tips
- Pre-Cutting is Key: Always prioritize getting the flip key blade cut before taking apart your working key to avoid any vehicle immobilization issues.
- Transponder Placement: While technically possible to bypass the transponder system by permanently affixing the chip near the ignition switch, this is strongly discouraged as it completely disables your car’s anti-theft system.
- Sourcing Parts: Online marketplaces like eBay are good sources for used keys and flip key housings. Ensure compatibility before purchasing.
- Professional Help: If you are uncomfortable with any part of this process, consult a professional locksmith or car audio specialist for assistance.
Conclusion
Upgrading to a flip key for your 2006 Mitsubishi Eclipse is a worthwhile modification that enhances both the style and convenience of your vehicle. By carefully following these steps and taking your time, you can successfully convert your standard key fob to a modern flip key, adding a touch of contemporary functionality to your classic sports car.
