From learning how to open the Honda key fob to finding the proper battery size, learn everything you need to know about the Honda key fob battery replacement process with Honda of Mentor.

Steps to Change the Battery in a Honda Key Fob

Before you get started in Willoughby, you’ll need a few items to change the battery in your Honda key fob: small (jeweler’s) screwdriver, flathead screwdriver, and a Honda key battery. If you don’t have a spare battery on hand, feel free to head to our parts department in Mentor. When you’ve got everything ready to go, here’s how to change your Honda key battery:

  1. Find the small screw holding the Honda key together. Remove it with the jeweler’s screwdriver.
  2. Use the flathead screwdriver to pry apart the two pieces of the key fob, but do so carefully. Make sure the pieces don’t fall loose as you open it.
  3. Locate the battery and pay attention to the orientation of the positive and negative sides. Remove the battery carefully, trying not to touch the terminals.
  4. Insert the battery in the same position as the old battery.
  5. Align the halves of the key fob and snap back into place.
  6. Replace the small screw.

Finding the Right Honda Key Fob Battery

Learning how to change the battery in a Honda key fob is simple, but what if you don’t know what replacement battery you need? One easy way to check is to remove your your old Honda key battery and take a look. Sometimes you can find the size and voltage label. However, sometimes it’s illegible. In that case, your Honda key fob battery replacement is most likely a 3-volt circular battery found at most Eastlake stores. You can also check with our technicians and order a replacement from our parts center.
