Is your 2008 Mitsubishi Eclipse key fob not working as reliably as it used to? Before you assume there’s a major issue with your keyless entry system, the most common culprit is often just a dead or dying key fob battery. Replacing the battery in your 2008 Mitsubishi Eclipse key fob is a simple and inexpensive task you can easily do yourself. This guide will walk you through the process step-by-step, saving you time and potentially a trip to the dealership.
Identifying the Right Battery for Your 2008 Mitsubishi Eclipse Key Fob
The first step is to identify the correct replacement battery. For the 2008 Mitsubishi Eclipse key fob, you’ll typically need a CR1620 battery. This is a common 3V lithium coin cell battery that’s widely available at most drugstores, supermarkets, and online retailers. To be absolutely sure, it’s always best to double-check your owner’s manual or, once you open your key fob, examine the old battery for its type. Using the correct battery type ensures optimal performance and longevity for your key fob.
Tools You’ll Need for the Battery Replacement
Fortunately, you won’t need any specialized tools for this task. In most cases, you’ll only require a small flathead screwdriver or a similar thin tool to gently pry open the key fob casing. Having a soft cloth or plastic prying tool can also be helpful to prevent scratches on your key fob. Make sure you have your replacement CR1620 battery ready before you begin the process.
Step-by-Step Guide to Replacing Your 2008 Eclipse Key Fob Battery
Replacing the battery is straightforward. Follow these simple steps:
Step 1: Open the Key Fob Casing
Locate the small notch or seam on your Mitsubishi Eclipse key fob. This is usually found along the side or near the key ring attachment. Using your flathead screwdriver or prying tool, carefully insert it into the notch and gently twist or pry to separate the two halves of the key fob casing. Take your time and avoid applying excessive force to prevent damage to the plastic.
Step 2: Remove the Old Battery
Once the key fob is open, you’ll see the battery compartment. The CR1620 battery will likely be held in place by small clips or pressure contacts. Note the orientation of the old battery (positive side up or down) before removing it. You can use your fingertip or the tip of the screwdriver to gently nudge the old battery out of its compartment.
Step 3: Insert the New Battery
Take your new CR1620 battery and insert it into the battery compartment, ensuring it’s in the same orientation as the old battery you removed. The positive (+) side of the battery should usually face upwards, but again, double-check the markings inside the battery compartment if you are unsure. Press down firmly but gently to ensure the battery is securely seated in place.
Step 4: Close the Key Fob Casing
Carefully align the two halves of the key fob casing and press them back together until they snap securely into place. Ensure there are no gaps and the casing is fully closed to protect the internal components from dust and moisture.
Step 5: Test Your Key Fob
Finally, test your 2008 Mitsubishi Eclipse key fob to ensure the battery replacement was successful. Try locking and unlocking your car doors, activating the panic button, and starting your vehicle (if your key fob includes immobilizer functions). If everything works as expected, you’ve successfully replaced your key fob battery!
Tips for Maintaining Your Key Fob Battery
To prolong the life of your 2008 Mitsubishi Eclipse Key Fob Battery, avoid exposing it to extreme temperatures or humidity. If you are not using your spare key fob for an extended period, consider removing the battery to prevent potential leakage. Keep spare batteries on hand so you’re prepared when the low battery indicator (if applicable) appears or when you notice your key fob range diminishing.
Replacing the battery in your 2008 Mitsubishi Eclipse key fob is a simple maintenance task that can save you from keyless entry frustrations. By following these steps, you can ensure your key fob is always ready to keep you connected to your vehicle.
