Replacing the battery in your 2016 Mazda CX-9 Signature key fob is a quick and easy DIY task. Here’s a step-by-step guide to help you through it:
- Locate the Key Fob Slot: On the back of your key fob, you’ll find a small slot. This is where you’ll insert the key to open the fob casing.
- Open the Fob Casing: Insert the key (or a small flat-head screwdriver) into the slot and gently pry open the casing. Be careful not to use excessive force to avoid damaging the fob.
- Identify the Battery: Inside, you’ll see the CR2032 battery nestled in place.
- Remove the Old Battery: Gently pry out the old battery using a small flat-head screwdriver or your fingernail. Pay attention to the battery’s orientation (+/-).
- Insert the New Battery: Insert the new CR2032 battery, ensuring the positive (+) side faces up, matching the orientation of the old battery.
- Reassemble the Fob: Align the two halves of the key fob casing and press them together firmly until you hear a click, indicating they’re securely closed.
Testing Your New Key Fob Battery
After replacing the battery, test all the key fob buttons to ensure they are working correctly. Try locking and unlocking your car from a short distance to confirm the increased range.
Still Having Issues?
