Gathering Your Supplies

Locating the Battery Compartment
The first step is to locate the battery compartment on your Acura MDX key fob. The location may vary slightly depending on the year and model of your MDX, but it’s typically found on the back of the fob, often concealed by a small cover.
Opening the Key Fob
Once you’ve located the battery compartment, you’ll need to open it. This is usually done by:
1. Finding the release tabs: Look for small tabs or grooves on the back of the key fob.
2. Using the screwdriver or coin: Gently insert the screwdriver or coin into the release tabs and pry open the key fob. Be careful not to apply excessive force, as this could damage the fob.
Removing the Old Battery
Inside the battery compartment, you’ll find the old CR2032 battery. It’s usually held in place by a small metal clip or spring. To remove the old battery:
1. Remove the clip or spring: If there’s a clip or spring, gently lift it out of the way.
2. Remove the battery: Carefully lift the old battery out of its compartment.
Installing the New Battery
Now it’s time to install the new CR2032 battery. Make sure the positive (+) side of the battery faces up, towards the top of the key fob.
1. Insert the battery: Gently slide the new battery into its compartment.
2. Replace the clip or spring: If you removed a clip or spring, make sure to put it back in place to secure the battery.
Closing the Key Fob
Once the new battery is in place, you can close the key fob. Gently press the two halves of the fob together until they snap securely.
Testing the Key Fob
After closing the key fob, it’s essential to test if the battery replacement was successful. Try using the key fob to unlock and lock your Acura MDX. If the key fob works, you’ve successfully replaced the battery!
Troubleshooting Battery Replacement Issues
If your key fob still isn’t working after replacing the battery, there might be a few other issues:
- Battery connection: Make sure the new battery is properly seated in its compartment and that the positive (+) side is facing up.
- Battery type: Double-check that you installed the correct CR2032 battery.
- Key fob damage: If the key fob has been dropped or damaged, the internal circuitry might be faulty.
- Programming issues: In rare cases, the key fob might need to be reprogrammed after replacing the battery. Consult your Acura owner’s manual or a qualified technician for assistance.
