Step-by-Step Battery Replacement

Step 1: Release the Internal Key

Start by pulling on the lever on the front of the key fob. Hold it down to release the internal key. This step is crucial for accessing the battery compartment.

Step 2: Insert the Screwdriver

Next, locate the metal keyring on the key fob. Insert your flat-head screwdriver between the keyring and the lip on the back of the key fob. Ensure the screwdriver is securely in place.

Step 3: Create Separation

Gently twist the screwdriver to create separation between the two halves of the key fob. You should feel a slight pop, indicating that the parts are starting to come apart.

Continue twisting and working your way down the side of the key fob until the two halves are completely separated.

Step 4: Remove the Old Battery

With the key fob open, you can now see the battery. Use your flat-head screwdriver to gently pry the old battery out from its compartment. Be cautious not to damage any components.

Step 5: Insert the New Battery

Take your new CR2032 battery. Ensure the positive side (with battery info) is facing up. Slide the battery into the compartment and press it down until it sits flush.

Step 6: Reassemble the Key Fob

Once the new battery is in place, align the two halves of the key fob and press them together until they click securely. Finally, reinsert the internal key.

Test the key fob by pressing any button. If the light comes on, you’ve successfully replaced the battery.

Conclusion

Replacing the battery in your Acura MDX key fob is a straightforward process. With just a flat-head screwdriver and a new CR2032 battery, you can ensure your key fob functions correctly. Regular maintenance of your key fob will save you from potential inconveniences.
