Step-by-Step Battery Replacement Process
Follow these steps to efficiently replace the battery in your Mazda CX-9 key fob.
Removing the Valet Key
First, turn the key fob over and locate the small lever. Push this lever down to release and remove the valet key. This step is crucial as it allows access to the internal components of the key fob.
Opening the Key Fob
Once the valet key is removed, look for the grooves on the inside of the key fob. Using a flat-head screwdriver, insert it into these grooves. You’ll feel it lock into place. Give it a slight twist to create separation. Repeat this on the groove on the other side.
After creating the separation, insert the screwdriver into the opening and move it down, giving it another twist. The key fob should come apart easily, exposing the battery compartment.
Removing the Old Battery
With the key fob open, you’ll see a piece of plastic protecting the battery. Remove this plastic piece carefully. Using your finger, slide out the old CR2025 battery.
Inserting the New Battery
Take the new CR2025 battery and place it in the compartment. Ensure the small rubber piece is correctly positioned before closing the key fob. This rubber piece is crucial for the proper functioning of the key fob.
Reassembling the Key Fob
Once the new battery is in place, click the back of the key fob back into position. Ensure everything is secure and properly aligned. Finally, reinsert the valet key into its slot.

Alternative Method Without a Screwdriver
If you don’t have a screwdriver on hand, there’s an alternative method to open the key fob using just your fingernails.
Using Fingernails to Open the Key Fob
Insert your fingernails into the corner grooves of the key fob. Apply a little force to create a separation. Once there’s a slight opening, insert the valet key halfway into the slot.
Twist the key lightly to further open the key fob. This method prevents any potential damage that might occur when using a screwdriver.
Replacing the Battery
After opening the key fob, follow the same steps as before: remove the plastic piece, slide out the old battery, insert the new one, and reassemble the key fob.
