A dead key fob battery can be a real pain, leaving you stranded and unable to unlock your Mazda CX-5. Fortunately, changing the battery is a quick and easy process you can do yourself, saving you a trip to the dealership. This guide will walk you through the steps to replace your Mazda CX-5 key fob battery like a pro.
What You’ll Need
Before you begin, gather the following items:
- A new CR2032 battery (available at most grocery stores, auto parts stores, and online)
- A small flat-head screwdriver
- Optional: A small plastic pry tool (to avoid scratching your key fob)
Step-by-Step Guide
Follow these simple steps to replace your Mazda CX-5 key fob battery:
-
Locate the release button: On the back of your key fob, find the small, round release button. It’s usually located near the key ring.
-
Release the key: Press and hold the release button while gently pulling out the metal emergency key from the fob.
-
Separate the fob halves: With the key removed, you’ll notice a small seam running around the edge of the fob. Carefully insert the tip of your flat-head screwdriver (or plastic pry tool) into the seam and gently pry the two halves of the fob apart. Be careful not to use excessive force, as this could damage the fob.
-
Remove the old battery: Once the fob is separated, you’ll see the old CR2032 battery inside. Carefully pry out the old battery using your screwdriver or pry tool.
-
Install the new battery: Insert the new CR2032 battery into the compartment, ensuring the positive (+) side faces up. You may hear a slight click when the battery is properly seated.
-
Reassemble the fob: Align the two halves of the key fob and press them firmly together until you hear a click, indicating they are securely closed.
-
Reinsert the emergency key: Slide the metal emergency key back into its slot on the fob until it locks into place.
-
Test the key fob: Press any button on the key fob to ensure it’s functioning properly. If not, double-check that the battery is correctly installed and the fob is closed tightly.
Troubleshooting
If you’re still experiencing issues with your Mazda CX-5 key fob after replacing the battery, here are a few things to check:
-
Battery orientation: Make sure the new battery is inserted with the positive (+) side facing up.
-
Battery contacts: Inspect the battery contacts inside the fob for any dirt or corrosion. If necessary, clean them gently with a cotton swab and rubbing alcohol.
-
Key fob programming: In rare cases, your key fob may need to be reprogrammed after a battery change. Consult your Mazda owner’s manual or contact a certified Mazda technician for assistance.
