This guide will walk you through each step to quickly and efficiently replace your Mitsubishi Outlander key fob battery, saving you time and a trip to the dealership.
Tools and Materials You’ll Need
Before you begin, gather these simple tools and materials. Having everything ready will make the process smooth and efficient.
- CR1620 Battery: This is the specific type of battery your 2018 Mitsubishi Outlander key fob requires. Ensure you have a fresh one on hand.
- Small Phillips Head Screwdriver: You’ll need this to remove a tiny screw on your key fob. Precision screwdrivers work best for these delicate tasks.
- Flathead Screwdriver or Pry Tool: A flathead screwdriver or a specialized plastic pry tool will help you gently open the key fob casing without causing damage.
Step-by-Step Guide to Battery Replacement
Follow these detailed steps to replace your 2018 Mitsubishi Outlander Key Fob Battery. Take your time and be gentle, and you’ll have your key fob working again in no time.
Step 1: Locate and Remove the Key Fob Screw
Turn your Mitsubishi Outlander key fob over to the back. You’ll see a small, usually silver, Phillips head screw securing the casing. Using your small Phillips head screwdriver, carefully unscrew and remove this screw. Place the screw in a safe spot where you won’t lose it.
Step 2: Carefully Open the Key Fob Casing
Once the screw is removed, examine the edge of your key fob. You’ll notice a small seam running around the perimeter. This is where the two halves of the key fob casing join together. Find a small slot or indentation along this seam. Insert your flathead screwdriver or pry tool into this slot. Gently twist or pry to separate the two halves of the key fob. Work your way around the seam if needed, applying gentle pressure until the case pops open.
Step 3: Access and Remove the Old CR1620 Battery
With the key fob open, you’ll see the internal components and the battery compartment. The CR1620 battery will be visible, held in place by small clips or within a compartment. Note the orientation of the battery – specifically, which side is facing up (+ or positive side). This is important for installing the new battery correctly.
To remove the old battery, you might find a small opening or notch near the battery. You can use a precision screwdriver, a pin, or even a toothpick to gently pry the battery out. Be careful not to damage the surrounding components. Gently push or pry at the edge of the battery until it lifts out of its compartment.
Step 4: Install the New CR1620 Battery
Take your new CR1620 battery and ensure you are inserting it with the positive (+) side facing upwards, matching the orientation of the old battery you just removed. Slide the new battery into the compartment, usually sliding one edge under retaining clips first and then pressing down on the opposite side to snap it securely into place. You should feel it click or sit snugly in its position.
Step 5: Reassemble the Mitsubishi Outlander Key Fob
Carefully align the two halves of the key fob casing back together. Press them firmly until they snap back into place. Ensure the seam is closed evenly all around.
Step 6: Reinstall the Screw
Retrieve the small Phillips head screw you removed in Step 1. Place it back into its hole on the back of the key fob and tighten it gently with your Phillips head screwdriver. Do not overtighten, as this could damage the plastic casing.
Step 7: Test Your Key Fob
Now, test your newly battery-powered key fob! Press any button – lock, unlock, or panic. You should see the indicator light on the key fob illuminate, and your Mitsubishi Outlander should respond to the command. If everything works as expected, congratulations, you’ve successfully replaced your 2018 Mitsubishi Outlander key fob battery!
Troubleshooting: What if it Still Doesn’t Work?
If your key fob is still unresponsive after replacing the battery, consider these troubleshooting steps:
- Check Battery Orientation: Double-check that you installed the new CR1620 battery with the positive (+) side facing up. Incorrect orientation is a common mistake.
- Battery Quality: Ensure you are using a fresh, high-quality CR1620 battery. Old or low-quality batteries may not provide enough power.
- Key Fob Cleanliness: Inspect the battery contacts inside the key fob for any dirt, dust, or corrosion. Gently clean the contacts with a soft, dry cloth if necessary.
- Resyncing (If Applicable): While not always necessary for battery changes, some vehicles might require key fob resyncing after battery replacement. Consult your 2018 Mitsubishi Outlander owner’s manual for any specific resyncing procedures.
- Professional Help: If you’ve tried these steps and your key fob still doesn’t work, there might be a more complex issue with the key fob itself. In this case, it’s best to consult with a qualified automotive locksmith or your Mitsubishi dealership for further diagnosis and repair.
