Over time, the battery in your key fob may begin to lose its charge, leading to reduced functionality. However, replacing the battery is a simple process that can be done at home with a few basic tools. In this guide, we will walk you through the step-by-step process of changing the battery on your Mazda CX-5 key fob, ensuring you can continue to enjoy the convenience it provides.

Before You Begin

Before you start replacing the battery on your Mazda CX-5 key fob, it’s important to gather the necessary materials and take a few precautions. Here’s what you’ll need:

– A new CR2025 battery (or the battery specified for your key fob model)
– A small flathead screwdriver or a plastic pry tool
– Clean cloth or tissue
– Safety gloves (optional)

Now, let’s delve into the step-by-step process of changing the battery on your Mazda CX-5 key fob.

Step 1: Locate the Battery Compartment

1. Start by locating the battery compartment on your Mazda CX-5 key fob. The exact location may vary slightly based on the key fob model, but it’s typically situated on the backside of the key fob.

2. Examine the key fob for a small indentation or slot. This is usually located near the edge or the side of the key fob. This indentation is the access point to the battery compartment.

Step 2: Open the Battery Compartment

1. Insert a small flathead screwdriver or a plastic pry tool into the indentation or slot you located in the previous step.

2. Gently twist or pry the screwdriver to pop open the battery compartment cover. Be careful not to apply excessive force to avoid damaging the key fob or injuring yourself. If the cover does not easily open, double-check that you are using the correct slot or indentation.

3. Once the battery compartment cover is loose, carefully lift it using your fingertips to expose the battery inside.

Step 3: Remove the Old Battery

1. Take note of the orientation of the old battery before removing it. Observe the positive (+) and negative (-) sides of the battery, as this will be important when installing the new battery.

2. Using your fingers or a non-metallic tool, gently pry the old battery out of its compartment. Take care not to damage any other components or circuitry inside.

3. Dispose of the old battery properly according to your local regulations. Lithium batteries should not be thrown in the regular trash.

Step 4: Install the New Battery

1. Take the new CR2025 battery or the battery specified for your key fob model and ensure it is properly oriented. The positive (+) side of the battery should be facing up.

2. Carefully place the new battery into the battery compartment, aligning it with the proper polarity.

3. Press down on the battery gently to ensure it is securely seated in the compartment.

Step 5: Close the Battery Compartment

1. Align the battery compartment cover with the key fob and carefully press it back into place. You should hear a click or feel it snap shut.

2. Give the key fob a gentle shake to ensure the battery is securely in place. If you hear any rattling or the cover pops open easily, double-check the installation.

Step 6: Test the Key Fob

1. With the new battery installed, test the key fob by pressing the buttons to lock, unlock, and remotely start your Mazda CX-5.

2. If the key fob functions as expected, you have successfully changed the battery. If not, double-check the battery orientation and ensure it is securely installed.

Replacing the battery in your Mazda CX-5 key fob is a straightforward process that can be easily done at home. By following these simple steps, you can ensure your key fob continues to operate smoothly and reliably. Remember to dispose of the old battery responsibly and keep a spare CR2025 battery on hand for future replacements. Enjoy the convenience and peace of mind that comes with a properly functioning key fob for your Mazda CX-5.
