Having a dead key fob battery is frustrating, especially when you’re in a hurry. If you’re driving a 2018 Mazda CX-9 and noticing your key fob is acting up, it might be time for a battery replacement. This article will guide you through everything you need to know about your 2018 Mazda CX-9 key fob battery, from identifying the signs of a dying battery to replacing it yourself.
Signs Your 2018 Mazda CX-9 Key Fob Battery Needs Replacing
Just like your car battery, your key fob battery relies on a small charge to send signals to your car. Over time, this charge depletes, leading to a weakened signal and eventual failure. Here are some common signs that your 2018 Mazda CX-9 key fob battery is nearing its end:
- Decreased Range: You might find yourself having to stand closer to your vehicle to lock, unlock, or start it.
- Intermittent Functioning: The key fob might work sometimes and then inexplicably stop working other times.
- Warning Light on Dashboard: Some models may display a warning light on the dashboard indicating a weak key fob battery.
- Slow Response Time: There’s a noticeable delay between pressing a button on your key fob and the car responding.
How to Replace Your 2018 Mazda CX-9 Key Fob Battery
Replacing your key fob battery is a simple task that you can do yourself at home with a few basic tools. Here’s a step-by-step guide:
- Gather Your Supplies: You’ll need a small flat-head screwdriver, a new CR2032 battery (commonly available at electronics stores), and your 2018 Mazda CX-9 key fob.
- Open the Key Fob: Locate the small notch or slot on the side of your key fob. Insert the flat-head screwdriver gently and pry open the casing. Be careful not to damage the internal components.
- Access the Battery: Once the key fob is open, you’ll see the battery. It’s typically held in place by a small clip or tab. Carefully remove the old battery.
- Insert the New Battery: Insert the new CR2032 battery, making sure the positive (+) side faces up, just like the old battery.
- Reassemble the Key Fob: Align the two halves of the key fob and press them together until you hear a click, indicating it’s securely closed.
- Test Your Key Fob: Try locking and unlocking your car, and starting the engine to ensure the new battery is working correctly.
