The Honda key fob is a useful part of every new Honda vehicle, providing easy and secure access to your ride. But what if your Honda key fob is acting up? Your Honda key battery may need changing. It’s a simple enough process that any Dover driver can do if they have a little advice. Dover Honda covers how to change the Honda key battery below!

How to Change the Battery in a Honda Key Fob: Finding the Right Battery 

The most important part of this process is choosing the proper replacement battery. Check out the back of the key fob for a text that indicates the Honda key fob battery type. If you can’t find it, don’t worry! You’ll be able to track down the appropriate battery in other ways. 

  • Owner’s Manual: Check your owner’s manual to see if the proper key fob battery type is indicated therein. 
  • Flat Circular 3-Volt: Most Honda key fob batteries are this type, easily available around Portsmouth. 
  • Parts Center: A Rochester-area parts store is going to have or order the exact kind of battery you need. 

Honda Key Fob Battery Replacement: Step-by-Step 

Once you’ve gotten the Honda key fob battery, it’s time to replace it! Just gather some small screwdrivers and a tool to remove the key before you follow a few simple steps: 

  • How to Open a Honda Key Fob: Almost every Honda key fob can be opened by using a very small screwdriver on a very small screw. After you do that, gently nudge the Honda key fob open with a flathead. 
  • Remove the Old Battery: Using a tool so your skin doesn’t corrode the surface, take the battery out. Pay attention to where the positive (+) and negative (-) ends of the battery have gone. 
  • Replace Honda Key Fob Battery: Place the new battery in
  • Reassemble the Key Fob: Gently press the two ends of the key fob back together. Now try out the key fob and make sure it’s working! 

If you’re having trouble with the installation, or your battery doesn’t work, it’s always wise to schedule service around Somersworth!
