What You’ll Need to Change Your CX-5 Key Fob Battery
Before you begin, gather the following items:
- A new CR2032 battery (widely available at most stores)
- A small flat-head screwdriver
- Your Mazda CX-5 key fob
Step-by-Step Guide to Changing the Battery in Your CX-5 Key Fob
Follow these easy steps to replace your CX-5 key fob battery:
- Locate the notch on the side of your key fob. This notch is usually located near the bottom corner where the metal key inserts.
- Insert the flat-head screwdriver into the notch and gently pry open the key fob. Be careful not to use excessive force, as this could damage the fob’s casing.
- Once the key fob is open, carefully separate the two halves to expose the battery. Take note of the battery’s orientation for correct replacement.
- Use your fingernail or the edge of the screwdriver to gently lift and remove the old battery. Avoid touching the battery’s flat surfaces.
- Align the positive (+) side of the new CR2032 battery with the positive (+) marking inside the key fob.
- Gently press the new battery into place. You should hear a slight click when the battery is properly seated.
- Align the two halves of the key fob and press them firmly together until you hear a snap, indicating the fob is securely closed.
Testing Your New Key Fob Battery
After replacing the battery, test your key fob by attempting to lock and unlock your CX-5. The buttons should now function correctly. If your key fob still doesn’t work, ensure the battery is properly installed and that the contacts are clean.
Tips for Maintaining Your CX-5 Key Fob
- Always handle your key fob with care to avoid dropping it or exposing it to extreme temperatures. Physical damage can affect the battery’s performance.
- Store your spare key fob in a safe and dry place. This will ensure it’s ready to use when you need it.
- Consider changing your key fob battery every 2-3 years as a preventative measure, even if it’s still working.
