How to Change Car Key Battery Mitsubishi Outlander? Easy Steps

Your car key is more than just a metal object; it’s the gateway to your Mitsubishi Outlander. It grants you access to your vehicle, starts the engine, and often houses essential security features. But what happens when this crucial tool fails to cooperate? A common culprit is a depleted car key battery. Fortunately, replacing a car key battery in your Mitsubishi Outlander is a relatively straightforward task that can be accomplished with a few simple tools and a little patience. This comprehensive guide will walk you through the process step-by-step, empowering you to tackle this common car maintenance issue yourself and save money on costly locksmith services.

Understanding Your Mitsubishi Outlander Key

Before diving into the battery replacement process, it’s essential to familiarize yourself with the specific type of key you have. Mitsubishi Outlanders typically come equipped with either traditional key fobs or keyless entry systems.

Traditional Key Fobs

Traditional key fobs are the most common type and typically have a physical key blade and a separate button for locking and unlocking the doors. These fobs usually have a small battery compartment located on the back, often secured with a small screw.

Keyless Entry Systems

Keyless entry systems, often referred to as “smart keys,” are more advanced and typically don’t have a separate physical key blade. They use radio frequency (RF) technology to communicate with the vehicle. These systems often have a battery compartment located inside the key fob, requiring a different approach for battery replacement.

Tools You’ll Need

To successfully replace your Mitsubishi Outlander’s car key battery, you’ll need a few essential tools:

  • Small Phillips head screwdriver: This is used to remove the screws securing the battery compartment.
  • New car key battery: Ensure you purchase the correct battery type for your key fob model. Refer to your owner’s manual or the battery compartment for the specific battery size and type.
  • Small flathead screwdriver (optional): This can be helpful for prying open stubborn battery compartments.

Replacing the Battery in a Traditional Key Fob

Follow these steps to replace the battery in your traditional Mitsubishi Outlander key fob:

1. **Locate the Battery Compartment:** The battery compartment is typically located on the back of the key fob. Look for a small indentation or a seam that can be opened.

2. **Remove the Screws:** Use a small Phillips head screwdriver to carefully remove the screws securing the battery compartment.

3. **Open the Battery Compartment:** Once the screws are removed, gently pry open the battery compartment using a small flathead screwdriver or your fingernails. Be careful not to damage the key fob’s casing.

4. **Remove the Old Battery:** Carefully remove the old battery from the compartment. Note the positive (+) and negative (-) terminals. (See Also: How to Replace Toyota Car Key Battery? A Simple Step By Step Guide)

Keyless entry systems often have a more complex battery replacement process. Follow these general steps, but always refer to your owner’s manual for specific instructions for your Mitsubishi Outlander model:

1. **Locate the Battery Compartment:** The battery compartment for keyless entry systems is usually located inside the key fob. You may need to remove a small cover or push a button to access it.
