Sooner or later, you’re going to need a Ford key fob battery replacement. The good news is they’re easy to find, easy to replace, and they’re dirt cheap. If you’ve got a few bucks and a minute to spare, you can get the job done.
What kind of battery goes in a Ford key fob?
CR2025 3-volts. These are those tiny little coin-shaped batteries you see in remote controls, digital watches, and other gadgets. Who knows, you might actually have a few handy right now if you check your junk drawers. But if you don’t, they’re not hard to get ahold of.
Where Do I Find CR2025s and What Do They Cost?
You can find a CR2025 battery almost anywhere. If they sell batteries, they probably sell CR2025s. Next time you’re in line at the grocery store or the gas station, look at the battery rack and see if they have any available.
Prices will vary by brand and retailer, but if you’re spending more than two bucks per battery, you’re overpaying. You can get a 25-pack from Amazon for under ten dollars. That should last you longer than the key fob itself does.
Most Ford key fobs will use a pair of CR2025s stacked one on top of the other. In some instances you may see a CR2032 3-volt, so you’ll want to double-check what type your fob is carrying before you make a purchase.
That said, in many key fobs and other devices you can use CR2025s and CR2032s interchangeably. They’re both 3-volt batteries, both 20mm across, and only 0.7mm different in height. If it fits, it’ll work.
How to Replace a Ford Key Fob Battery
Different Ford key fobs will have different ways of accessing the battery. You can check this website to find out exactly how your key fob pops open, but it generally comes down to the same steps no matter your model.
- Open the key fob. This will typically involve popping the fob apart at the seam, or pressing a tab in the key slot.
- Make a note of where the old battery is and how it’s positioned. You’ll want the replacement battery to match it.
- Swap the batteries out and dispose of the old ones.
- Pop the key fob back together.
If replacing the battery doesn’t fix the issue, you can troubleshoot with a system reset to find out if it might be the fob itself or the fuses, rather than dead batteries.
