Lost your key fob or looking to upgrade to a flip key for your 2006 Mitsubishi Eclipse? Programming a new key fob might seem daunting, but it can be done, potentially saving you a trip to the dealership. This guide, based on user experiences, explores how you can approach 2006 Mitsubishi Eclipse Key Fob Programming yourself.
Understanding Your 2006 Eclipse Key System
The key system in your 2006 Mitsubishi Eclipse involves two main components: the transponder for starting the engine and the key fob for remote locking/unlocking. Older aftermarket keys might separate these functions. Some keys have a transponder chip embedded within the key itself, while a separate fob handles remote functions. Upgrading to a flip key often involves combining these functionalities into a single, more modern key.
Converting an Aftermarket Key to a Flip Key
One user shared their experience of converting an existing aftermarket key. This method focuses on salvaging the transponder from an older key and integrating it into a new flip key. Here’s a breakdown of the process:
Extracting the Transponder Chip
If you have an existing aftermarket key, carefully examine it. Some are designed to be opened. By gently using a razor blade along the seam of your aftermarket key, you might be able to split it open. Inside, you may find a small black chip, often housed in a white holder. This is the crucial transponder chip that is programmed to your car’s Engine Control Unit (ECU). Carefully remove this chip.
Installing the Transponder in a Flip Key
Obtain a compatible flip key designed for Mitsubishi vehicles. These are readily available online. These flip keys often have a small, unused cavity near the “flip” button. This cavity is designed to house a transponder chip. Insert the transponder chip you extracted from your old key into this cavity.
Important Note: Before disassembling your working key, ensure you have a new key blade cut for your flip key. You can typically get a key blade cut at a locksmith or some hardware stores.
Programming the Remote Fob Function
Simply having the transponder in the flip key will allow you to start your car if the key blade is correctly cut. However, to regain remote locking/unlocking and trunk release functionality, you’ll need to program the fob portion of a new or used key fob.
Acquiring a Compatible Key Fob
The user suggests searching online marketplaces for a used “cut” key that includes the fob. The “cut” refers to the key blade, but the important part is obtaining the intact fob module within the key housing. Once you have this used key, carefully dismantle it to remove the fob module from the diamond-shaped section of the key.
Programming the Fob to Your Eclipse
The original post mentions using instructions found elsewhere to program the fob using a paper clip and the OBDII port. It’s crucial to verify these programming instructions are accurate and safe for your 2006 Mitsubishi Eclipse before attempting them. Incorrect procedures could potentially cause issues with your car’s electronics. Search online forums and reputable sources specifically for “2006 Mitsubishi Eclipse key fob programming instructions” to find the correct steps. These instructions usually involve a sequence of actions with the ignition and door locks, sometimes utilizing the OBDII port for specific models.

- Transponder is Essential for Starting: The transponder chip is what allows your car to start. Handle it with care.
