Is your 2018 Mazda CX-5 key fob acting up? Before you panic and schedule a pricey dealership visit, you might just be dealing with a simple battery issue. Yes, even those seemingly complex key fobs rely on a good old-fashioned battery to function! This guide will walk you through everything you need to know about your 2018 Mazda CX-5 key fob battery, from identifying the signs of a dying battery to replacing it yourself like a pro.
How to Tell if Your 2018 Mazda CX-5 Key Fob Battery Needs Replacing
Just like your car battery, your key fob battery won’t last forever. Here are some telltale signs that it’s time for a swap:
- Decreased Range: Are you finding yourself standing closer and closer to your CX-5 to get it to unlock? A weak battery can significantly reduce your key fob’s signal strength.
- Intermittent Functionality: If your CX-5 only responds to your key fob sporadically, it could be a sign that the battery is on its last legs.
- Warning Lights and Messages: Some CX-5 models may display a “Key Fob Battery Low” warning message on the dashboard.
- Slow Response Time: Is there a noticeable delay between pressing the button on your key fob and your CX-5 responding? This could point to a dying battery.
What Kind of Battery Does a 2018 Mazda CX-5 Key Fob Take?
The 2018 Mazda CX-5 key fob uses a CR2032 battery, a common type of lithium coin battery. You can find these batteries at most electronics stores, auto parts stores, and even some grocery stores.
How to Change the Battery in Your 2018 Mazda CX-5 Key Fob
Replacing the battery in your 2018 Mazda CX-5 key fob is a surprisingly simple DIY task. Here’s a step-by-step guide:
- Locate the Battery Compartment: Look for a small release button or notch on the back of your key fob.
- Open the Key Fob: Using a small flat-head screwdriver or your fingernail, gently pry open the key fob at the release point.
- Remove the Old Battery: Carefully remove the old CR2032 battery. Note the orientation of the positive (+) and negative (-) sides.
- Install the New Battery: Insert the new CR2032 battery into the compartment, making sure the positive (+) side is facing up (or as it was in the original orientation).
- Reassemble the Key Fob: Snap the two halves of the key fob back together.
Expert Tip: Avoid touching the top and bottom of the new battery with your bare fingers, as this can transfer oils that may shorten its lifespan. If you do touch it accidentally, gently wipe the surface with a clean cloth.
Testing Your New Key Fob Battery
Once you’ve replaced the battery, test your key fob to ensure everything is working correctly. Try locking and unlocking your CX-5, as well as using the remote start and panic button functions.
Can a Dead Key Fob Battery Leave Me Stranded?
Don’t worry, even with a completely dead key fob battery, you can still start your 2018 Mazda CX-5. Most modern cars, including the CX-5, have a backup system that allows you to start the car using a hidden key slot or by touching the key fob to a specific area on the steering column. Refer to your owner’s manual for the exact location and instructions for your model.
