Introduction to Mazda 3 Flip Key Fob Battery Replacement
Welcome to our step-by-step guide on replacing the battery in a Mazda 3 flip key fob. This guide is applicable for Mazda 3 models from 2010 to 2013. If your key fob isn’t functioning correctly, it’s likely time to replace its internal battery.
We’ll be using a CR1620 coin battery for this task, and the process is straightforward if you follow along carefully. Let’s dive into the details.

Tools and Materials Needed
Before we begin, let’s gather the necessary tools and materials. Here’s what you’ll need:
- CR1620 coin battery
- Flathead screwdriver
- Precision screwdriver
These tools will help you open the key fob and replace the battery with ease.
Step 1: Open the Key Fob
The first step is to open the key fob to access the battery compartment. Follow these instructions:
- Open the key to access the slot.
- Locate the plastic separation.
- Push to remove the top plastic piece.
If the plastic piece is tight, use a flathead screwdriver to create a separation. Hold onto the section that won’t move and push the edge to make a gap.
Step 2: Separate the Key Fob
Once you’ve made a separation, wiggle the flathead screwdriver and twist to separate the two parts of the key fob. Be careful with the circuit board inside. Ensure the buttons remain in place and secure.
Set the circuit board aside for now.
Step 3: Remove the Old Battery
Now that the key fob is open, you’ll see the CR1620 battery inside. It’s too deep to remove with your fingers, so you’ll need a precision screwdriver.
- Locate the arrow on the key fob.
- Insert the precision screwdriver into the gap.
- Pull back to pop the battery out.
This method involves finding the gap between the plastic and the battery, inserting the tool, and prying the battery out.
Step 4: Insert the New Battery
With the old battery removed, it’s time to insert the new CR1620 battery. Follow these steps:
- Ensure the side with the info faces down.
- Slide the battery up into the metal area.
- Push down on the bottom until it clicks.
Make sure the battery is properly seated and secure.
Step 5: Reassemble the Key Fob
Now that the new battery is in place, reassemble the key fob:
- Ensure the circuit board is in place.
- Line up the key fob parts.
- Secure everything together.
Double-check that everything is aligned and secure before closing the key fob.
