Our cars might not be able to fly just yet, but key fobs are a sure sign that we’re living in the 21st century. They’re also one more thing that can go wrong. Sooner or later, that Mazda CX-5 key fob battery is gonna burn out on you. What
kind of battery goes into a Mazda CX-5 key fob battery? A CR2025 3-volt. These are among the most common types of battery for small electronics. Basically, any gadget that fits in your pocket there’s a 50/50 chance it has a 2025 in it. You’ll find them in everything from toys and
digital watches to medical devices and remote controls of every variety. That leaves us with two questions: Where do we get a replacement CR2025 3-volt battery, and how do we get the old one out of the key fob? Read on and we’ll tell you everything you need to know about the Mazda CX-5 key fob battery.Where Can I Find One and How Much Will it Cost?
Because these batteries are so common, you can find them just about anywhere. You can pick them up at Wal-Mart, AutoZone, Family Dollar, gas stations, and convenience stores. Pretty much anywhere you can buy batteries, you can buy CR2025 3-volts.
Generally, you can expect them to range in price from around $2.50 to $5.00 for a single battery or a two-pack. Or if you want to save some money, and make sure you’re always prepared, you can buy a 25-pack for around ten bucks from Amazon.
Some drivers report that a CR2032 3-volt actually works better, extending the range of the key fob. The numbers refer to the physical size of the battery. A 2032 is 3.2mm, and a 2025 is 2.5mm.
The voltage is the same; you’re not going to fry your key fob upgrading the battery, so if a 2032 will fit, there’s no reason not to use it.
How Do I Replace a Mazda CX-5 Key Fob Battery?
Don’t worry, this is pretty easy. You don’t need any special hex keys; you don’t need to put on a pair of latex gloves and crack open the circuitry. If you’ve got a screwdriver and a minute to kill, you can get this done quick.
- Remove the key ring by pressing the tiny switch and pulling on the ring.
- Using your screwdriver, gently pop the key fob apart at the seam.
- Pull the battery cover off with your fingers.
- Remove the old battery and put the new one in its place.
- Put everything back together, take it out to the car, and test it out.
If your key fob isn’t working, then it might not be the battery. You can troubleshoot by resetting the system and testing the receiver. There’s not that much that can go wrong with the key fob, so it shouldn’t take all day to figure this one out.
