Step-by-Step Guide
Follow these steps to replace the battery in your Mazda 6 Sedan key fob.
Step 1: Open the Key Fob
First, you need to open the key fob to access the battery. Look for the indentation at the top of the keychain area. This small gap is between the two halves of the plastic casing.
Insert a flat head screwdriver or a similar tool into this indentation. If you don’t have a screwdriver, even a quarter can work. Twist the tool to pry open the key fob. Be gentle but firm to avoid damaging the plastic.
Step 2: Remove the Old Battery
Once the key fob is open, you will see the CR2025 battery. The battery might be difficult to remove with just your fingers. Use the same tool you used to open the fob to help dislodge the battery.
At the top where the keychain hole is located, you will notice some green plastic. Push on the bottom of the battery and wiggle it gently. This should release the battery from its compartment.
Step 3: Insert the New Battery
Take your new CR2025 battery and make sure the side with the brand and battery information is facing up. When inserting the battery, slide the bottom edge first into the compartment. This ensures that the battery fits behind the two small plastic pieces that hold it in place.
Once the bottom is in position, press down on the top edge of the battery until it clicks into place. Make sure the battery is securely seated in its compartment.
Step 4: Reassemble the Key Fob
Now that the new battery is in place, it’s time to reassemble the key fob. Align the two halves of the plastic casing and press them together until they snap back into place.
Ensure that the key fob is firmly closed and that there are no gaps between the two halves.
