Experiencing a finicky key fob for your Mazda CX-5? Before you schedule a trip to the dealership, a dead battery might be the culprit. Thankfully, replacing it is a quick and easy DIY project you can do at home. This guide will walk you through the simple steps to change the battery in your Mazda CX-5 key fob, getting you back on the road with a fully functioning key in no time.

What You’ll Need:

• A fresh CR2032 battery (easily found at most grocery stores, pharmacies, and online)
• A small flat-head screwdriver
• Your Mazda CX-5 key fob

Step-by-Step Guide to Replacing Your Mazda CX-5 Key Fob Battery:

1. Locate the release button: On the back of your key fob, find the small, round release button.
2. Release the metal key: Press the release button and gently pull out the metal emergency key from the fob.
3. Open the fob casing: Use the tip of your flat-head screwdriver to carefully pry open the key fob casing. Look for a small notch where the two halves of the fob connect. There’s no need to use excessive force – a gentle wedge and twist should pop it open.
4. Remove and replace the battery: Identify the CR2032 battery inside. Gently pry it out, noting the position of the positive (+) side, which should be facing up. Insert the new battery in the same orientation, ensuring a snug fit.
5. Reassemble the fob: Align the two halves of the fob casing and press them together until you hear a click, indicating they are securely closed.
6. Reinsert the metal key: Slide the metal key back into its slot on the fob until it locks in place.
7. Test your key fob: Try locking and unlocking your CX-5 to confirm the new battery is working correctly.
