Is your 2018 Mazda CX-5 key fob acting up? Before you rush to the dealership, a dead battery might be the culprit. Don’t worry, replacing it is a breeze even for the least tech-savvy car owner! This guide will walk you through the process step-by-step and get you back on the road in no time.
Replacing the battery in your 2018 Mazda CX-5 key fob is a surprisingly simple task that can save you the time and expense of a trip to the dealership. Let’s dive into the details!
What You’ll Need
Before you begin, gather these few items:
- A brand new CR2032 battery (you can find this at most grocery stores, pharmacies, and auto parts stores)
- A small flat-head screwdriver or a plastic pry tool
Locating the Battery Compartment
- Find the notch: Take a look at your Mazda CX-5 key fob. You’ll see a small notch on the side.
- Gently pry open the case: Carefully insert the flat-head screwdriver or pry tool into the notch and gently apply pressure to pop open the key fob casing.
- Identify the battery: Inside, you’ll find the round, flat CR2032 battery.
Replacing the Battery
- Remove the old battery: Gently pry out the old battery. Note the position of the positive (+) side, which should be facing up.
- Insert the new battery: Place the new CR2032 battery into the compartment with the positive (+) side facing up, just like the old one.
- Snap the casing back together: Align the two halves of the key fob casing and press firmly until you hear a click, indicating it’s securely closed.
Testing the Key Fob
Now that you’ve replaced the battery, it’s time to make sure everything is working correctly:
- Try locking and unlocking your car doors using the key fob buttons.
- If it doesn’t work immediately, don’t panic: Sometimes the key fob needs to resynchronize with your car. Refer to your owner’s manual for specific instructions on how to reprogram your key fob, or try locking and unlocking your car manually once using the key blade.
Signs You Might Need a New Key Fob Battery
Aside from your car not responding to the key fob, here are other signs that a dying battery might be the issue:
- Reduced signal range: You find yourself needing to be much closer to your car for the key fob to work.
- Dim or inconsistent key fob lights: The lights on your key fob are weaker than usual or flicker intermittently.
- Buttons require multiple presses: You have to press the buttons several times to get them to respond.
Replacing the battery in your 2018 Mazda CX-5 key fob is a quick and easy task that can prevent frustrating lockouts and costly trips to the dealership. With this simple guide, you can do it yourself in minutes!
