Your Honda key fob is invaluable; it lets you open your doors, trunk, and hood at the press of a button. But when the battery dies, all that utility goes to the wayside. Thankfully, you can easily get it going again with a flathead screwdriver and the right battery.
Which battery does your Honda key fob use?
Honda key fobs use the CR2032 3-volt battery. You will only need one for each remote and they are easy to install.
Where Can I Find a Honda Key Fob Battery and How Much is it?
The CR2032 3-volt battery is a common and widely available size. You’ll likely find it sitting in the battery section at your local hardware store or even the supermarket.
If you prefer to shop online, then you can order it from:
When buying batteries for multiple remotes, you can save money in the long run by buying a multi-pack for a bit more. Target has a two-pack for $5.49, while Walmart has them for $5.95. Lowe’s even has a six-pack of CR2032 batteries for $12.96.
Steps to Replace Your Honda Key Fob Battery
Once you have your CR2032 battery in hand, you can get to work on replacing the one in your Honda key fob. You just need to work through these steps to get it working again.
1. Slide the Metal Key Out of the Fob
To pop open the case and get to the battery, you first have to get the metal key out of the way. You can do that by gently pressing the small switch to release the key. Then, pull the key straight out and put it to the side.
2. Pop off the Back of the Case
Look where you just removed the key to find two black plastic tabs with a space in the middle. Put the tip of your flathead screwdriver between the tabs and slightly twist the handle to pop open the case.
Although you could use the key for this in a pinch, it’s better to use a screwdriver to avoid damaging the key. You’ll need the screwdriver in the next step anyway.
3. Gently Pry out the Battery
Set the other side of the case down and focus on the one with the battery inside. Gently slide your flathead screwdriver under the open side of the battery and it will pop out.
Make sure to immediately dispose of that battery in a secure garbage can. You do not want pets or kids getting to it.
4. Press the New Honda Key Fob Battery in Place
Slide the new battery under the tabs in the remote and press it down. The new battery should lightly click as it seats into place.
5. Put it Back Together
Carefully line up the back cover and press it firmly together until it clicks. Then, put the metal key back in the case to finish up this job.
With that done, go out to your 2020 Honda Ridgeline or another vehicle to test your key fob. That way, you don’t have any surprises the next time you have to leave the house.
If it doesn’t work, you might have gotten a bum battery or something could be wrong inside. Try again with another new battery, and then call the dealership for help fixing it if it still doesn’t work. When you come down, they will help you see if you need a new key fob.
