Are you looking to modernize your 2000 Mitsubishi Eclipse key? Many owners of this classic sports car are seeking a sleeker, more contemporary key design. The standard key, while functional, lacks the convenience and style of a flip key. Fortunately, converting your existing key fob to a flip key is a feasible DIY project. This guide will walk you through the process, drawing upon the experiences of enthusiasts who have successfully made this upgrade.
Understanding the Components
Before diving into the conversion, it’s crucial to understand the two main components within your car key: the transponder chip and the remote fob.
-
Transponder Chip: This is a small, passive microchip embedded within the plastic part of your key. It’s essential for starting your car. When you insert the key into the ignition, the car’s immobilizer system reads the unique code from the transponder chip. If the code matches the car’s ECU (Engine Control Unit), the engine is allowed to start. Without this chip, even if you have a mechanically cut key, your 2000 Mitsubishi Eclipse will not start.
-
Remote Fob: This is the electronic part of your key fob that allows you to remotely lock and unlock your doors and potentially open the trunk. It operates on radio frequencies and communicates with your car’s Body Control Unit (BCU).
Step-by-Step Conversion Guide
The conversion process involves carefully transferring these components into a new flip key casing. Here’s a breakdown of the steps based on community experiences:
1. Extracting the Transponder Chip from Your Original Key
This is the most delicate part of the process. You’ll need to carefully open your existing Mitsubishi Eclipse key.
- Locate the Seam: Examine your original key fob. You’ll find a seam line running along the plastic casing.
- Carefully Open the Key: Using a thin razor blade or a precision knife, gently pry open the key casing along the seam. Work slowly and carefully to avoid damaging the plastic or the components inside.
- Identify the Transponder Chip: Once open, locate a small black box or chip, often housed in a white plastic holder. This is your transponder chip. It does not have a circuit board and is purely a chip.
- Remove the Transponder Chip: Carefully remove the transponder chip from its holder. Handle it with care as it is crucial for starting your car.
2. Preparing the Flip Key
You’ll need to acquire a compatible flip key casing. These are readily available online, often marketed for Mitsubishi vehicles. Ensure you choose one that is compatible with the transponder chip and remote fob (if you intend to transfer the remote function) from your 2000 Mitsubishi Eclipse.
- Flip Key Cavity: Open the flip key casing. You’ll find a small cavity designed to house the transponder chip. This cavity is typically located near the button that flips out the key blade.
- Key Blade Cutting: Crucially, have the key blade for your flip key cut before you dismantle your original working key. Take the new flip key blade and your original key to a locksmith or key cutting service. They will cut the new blade to match your original key.
3. Assembling the Flip Key
Now, assemble your new flip key:
- Insert the Transponder Chip: Place the transponder chip you extracted from your original key into the designated cavity within the flip key casing. Ensure it fits snugly and is secure.
- Assemble the Flip Key Casing: Carefully close the flip key casing, ensuring it’s properly sealed.
4. Programming the Remote Fob (Optional)
If you want the remote locking/unlocking functionality in your flip key, you’ll need to transfer the remote fob from a compatible key and program it to your 2000 Mitsubishi Eclipse.
- Acquire a Used Key with Fob: Search online marketplaces like eBay for a used, uncut Mitsubishi key with the remote fob intact. It’s often more cost-effective to buy a used key than a new remote fob separately.
- Dismantle the Used Key: Once you have the used key, carefully dismantle it to extract the remote fob module. This is usually a small circuit board within the key casing.
- Install Fob in Flip Key: If your flip key casing has space for a remote fob (some are designed just for the transponder), install the fob module.
- Program the Fob: Programming the remote fob usually involves using a paper clip to bridge specific pins in the OBDII port (On-Board Diagnostics II port) under your dashboard and following a specific sequence of actions with the key and door locks. You can find detailed instructions for programming Mitsubishi key fobs online or in owner forums.
Important Considerations
- Key Blade First: Always get the flip key blade cut before you take apart your original working key. This ensures you always have a working key during the conversion process.
- Transponder is Essential: The transponder chip is vital for starting your car. Handle it with extreme care during the extraction and transfer process.
- Remote Fob Compatibility: Ensure the used remote fob you acquire is compatible with your 2000 Mitsubishi Eclipse. Check part numbers or consult online resources for compatibility information.
- Professional Help: If you are uncomfortable with any part of this process, especially opening the keys or programming the fob, consult a locksmith or automotive technician.
Conclusion
Converting your 2000 Mitsubishi Eclipse Key Fob to a flip key is a rewarding DIY upgrade that enhances both the style and convenience of your vehicle. By carefully following these steps and taking your time, you can successfully modernize your key and enjoy the benefits of a flip key design. Remember to prioritize getting the key blade cut first and handle the transponder chip with utmost care. With a bit of patience and attention to detail, you can achieve this upgrade and enjoy a more modern key for your classic Eclipse.
