How to Replace Acura MDX Key Fob Battery

Experiencing a flickering lock button or unresponsive key fob for your Acura MDX? Don’t panic, it might just be a dead battery. Luckily, replacing the battery in your Acura MDX key fob is a quick and easy task you can do yourself, saving you a trip to the dealership. Let’s walk through the simple steps.

What You’ll Need

Before you get started, gather these few items:

• Your Acura MDX key fob
• A small flat-head screwdriver
• A new CR2032 battery (easily found at most stores)

Step-by-Step Guide to Replacing Your Acura MDX Key Fob Battery

1. Open the Key Fob: Locate the small release button on the back of your key fob. Gently press the button while sliding the metal key blade out. This will separate the two halves of the key fob casing.

2. Access the Battery: Carefully pry open the two halves of the key fob using your flat-head screwdriver. Be gentle to avoid damaging the casing. Inside, you’ll see the round, flat CR2032 battery.

3. Remove and Replace: Note the position of the positive (+) side of the battery. Using your screwdriver (or even your fingernail), gently pry the old battery out. Insert the new CR2032 battery, making sure the positive (+) side faces the same direction as the old battery.

4. Reassemble the Key Fob: Align the two halves of the key fob casing and press them together firmly until you hear a click. Slide the metal key blade back into its slot.

5. Test Your Key Fob: Press the buttons on your key fob to ensure it’s working properly. If the buttons still don’t respond, double-check that the battery is correctly installed and that it’s a fresh, working battery.
