Identifying Battery Issues in Your 2003 Mazda 6 Key Fob

Several telltale signs can point to a dying key fob battery:

  • Decreased Range: Do you find yourself standing closer to your Mazda 6 to lock or unlock the doors? This reduced range indicates a weakening battery.

  • Warning Lights and Messages: Some Mazda 6 models may display warnings on the dashboard, signaling a low key fob battery.

The 2003 Mazda 6 key fob typically uses a CR2025 battery, a common type readily available at most electronics stores, supermarkets, and online retailers.

Here’s a simple guide to replace your 2003 Mazda 6 key fob battery:

  1. Locate the Key Fob’s Release Button or Notch: Examine your key fob for a small button or notch. This is usually located on the back or side.
  2. Separate the Key Fob Halves: Using a small flathead screwdriver or your fingernail, gently pry open the key fob case at the release point. Be careful not to damage the internal components.
  3. Identify and Remove the Old Battery: The CR2025 battery will be easily visible. Carefully remove it, noting the orientation (positive (+) side facing up).
  4. Insert the New Battery: Place the new CR2025 battery in the compartment, ensuring the positive (+) side matches the orientation of the old battery.
  5. Reassemble the Key Fob: Align the halves of the key fob and press them together until you hear a click, signifying they are securely closed.
