Is your 2007 Mitsubishi Outlander key fob starting to act up? You might be experiencing shorter range, or maybe it’s becoming increasingly intermittent. Before you rush to a dealership and spend a significant amount on a new key fob or service, consider a simple and cost-effective solution: replacing the battery. This guide will walk you through the process of changing the battery in your 2007 Mitsubishi Outlander key fob, saving you time and money. As your trusted automotive experts at keyfobprog.com, we’re here to provide you with clear, step-by-step instructions to get your key fob working like new again.
Recognizing the Signs of a Weak Key Fob Battery
Before diving into the replacement, it’s important to confirm that a low battery is indeed the issue. Here are common signs that your 2007 Mitsubishi Outlander Key Fob Battery is nearing the end of its life:
- Reduced Operating Range: You need to be much closer to your Outlander for the remote to lock or unlock the doors. What used to work from a distance now requires you to be right next to the vehicle.
- Intermittent Functionality: Sometimes the key fob works perfectly, and other times it seems unresponsive. You might have to press the buttons multiple times to get a reaction.
- Dashboard Warning Light (If Applicable): Some Mitsubishi Outlander models may display a warning light on the dashboard indicating a low key fob battery. Consult your owner’s manual to see if your model has this feature.
- Inconsistent Button Response: Certain buttons on your key fob might become less responsive than others. For instance, the lock button might work fine, but the unlock or panic button might be sluggish.
If you’re experiencing one or more of these symptoms, replacing your 2007 Mitsubishi Outlander key fob battery is likely the solution.
What You Will Need to Replace Your Key Fob Battery
Replacing your key fob battery is a straightforward DIY task that requires minimal tools. Here’s what you’ll need:
- New Battery: You’ll need a CR2032 3V lithium coin cell battery. This is the standard battery type for most Mitsubishi Outlander key fobs of this era. You can easily find these batteries at most drug stores, supermarkets, auto parts stores, and online retailers.
- Small Flathead Screwdriver or Pry Tool: A small flathead screwdriver or a plastic pry tool (like those used for electronics repair) will be necessary to open the key fob casing. Using a plastic tool is recommended to minimize the risk of scratching the fob.
- Soft Cloth (Optional): A soft cloth can be used to protect the key fob casing from scratches while you’re working on it.

Step-by-Step Guide to Battery Replacement
Now, let’s get to the battery replacement process. Follow these simple steps to change the battery in your 2007 Mitsubishi Outlander key fob:
-
Locate the Notch or Seam: Examine your Mitsubishi Outlander key fob closely. You should find a small notch or seam along the side of the casing. This is where you’ll need to insert your flathead screwdriver or pry tool to open the fob.
-
Carefully Open the Key Fob Casing: Gently insert the tip of your flathead screwdriver or pry tool into the notch or seam. Twist or pry carefully to separate the two halves of the key fob casing. Avoid using excessive force, as you could damage the plastic casing. If your key fob has a physical key, you might need to remove it first to access the opening point.

Identify the Battery Compartment: Once the key fob is open, you’ll see the internal components and the battery compartment. The CR2032 battery will be visible, usually held in place by small clips.
-
Remove the Old Battery: Take note of the battery’s orientation (+ side up or down) before removing it. You can typically pry the old battery out gently with your fingertip or the edge of your screwdriver. Be careful not to damage the surrounding circuitry.

- Insert the New CR2032 Battery: Place the new CR2032 battery into the compartment, ensuring that the polarity is correct (match the + and – signs with the markings in the battery compartment or the orientation of the old battery). Usually, the positive (+) side faces upwards.

-
Test Your Key Fob: Test all the buttons on your key fob – lock, unlock, trunk release, and panic – to ensure they are working properly. You should notice an immediate improvement in the range and responsiveness.
Tips for Maintaining Your Key Fob Battery
To prolong the life of your 2007 Mitsubishi Outlander key fob battery and prevent future issues, consider these tips:
- Avoid Extreme Temperatures: Extreme heat or cold can shorten battery life. Avoid leaving your key fob in direct sunlight or freezing temperatures for extended periods.
- Store Spare Battery: Keep a spare CR2032 battery at home or in your car so you’re prepared for unexpected battery failures.
- Regularly Check Functionality: Periodically check the range and responsiveness of your key fob to catch battery issues early.
Troubleshooting Key Fob Issues After Battery Replacement
In most cases, replacing the battery will solve the problem. However, if your 2007 Mitsubishi Outlander key fob still isn’t working correctly after replacing the battery, consider these troubleshooting steps:
- Double-Check Battery Polarity: Ensure that you inserted the new battery with the correct polarity (+ side up).
- Verify Battery Type: Confirm that you are using the correct CR2032 battery type.
- Inspect Battery Contacts: Check the metal contacts in the key fob battery compartment for any dirt, corrosion, or damage. Clean them gently if necessary.
- Key Fob Damage: If your key fob has been dropped or damaged, internal components might be broken. In this case, you may need to consider a replacement key fob.
- Vehicle Issues: In rare cases, the problem might not be the key fob itself but an issue with your Mitsubishi Outlander’s receiver system. If you suspect this, consult a qualified automotive technician.
If you’ve followed these steps and your 2007 Mitsubishi Outlander key fob is still not functioning, it might be time to seek professional help.
