Honda Key Fob Battery

Finding the right battery for your key fob is as simple as visiting a store around Irvine. The Honda key fob uses a flat circular 3-volt battery that’s commonly found in a well-stocked battery display or at our parts center.

How to Change Honda Key Battery: Opening the Case

Learning how to change the battery in a Honda key fob is relatively easy, but opening the key fob case can take some careful maneuvering. Follow these steps:

  • Find the button that releases the metal key inside the fob and slide it open to pull the key out. 
  • Using the edge of the key, carefully insert it into the notch at the key fob, wedge the key in it, and lightly twist it to pop off the back of the key fob. Take care to ensure the rest of the key fob parts don’t fall apart. 

How to Change Honda Key Battery: Placing the Honda Key Battery

The inside of the Honda key fob has essential components that you should make sure aren’t lost or damaged when trying to pull the battery out. Here’s how to keep your key fob intact while performing a Honda key fob battery replacement: 

  • Place your thumb right above where the battery is located.
  • With your other hand, gently pry the dead battery out and place the new Honda key battery in its place.
  • Align both sides of the key fob again and carefully press the pieces back together. You’ll hear a snap once they are secured. 

How to Program Honda Key

Now that you’ve changed the battery in a Honda key fob, it’s a good idea to check that it’s working how it used to, so your trips around Costa Mesa aren’t interrupted. You’ll find that learning how to program a Honda key is simple. Follow these quick steps: 

  1. Enter your vehicle with any key fobs that need to be programmed and close all the doors. 
  2. Insert the key and turn to the “On” position, then hold the “LOCK” button for one second.
  3. Once you release the button, turn the key to the “Off” position. Follow steps 2 and 3 two more times. 
  4. Once again, turn the key to the “On” position and hold the “LOCK” button on the key fob for one second. You’ll hear the doors lock and unlock automatically. This means the vehicle has entered remote programming mode. 
  5. For the last time, hold the “LOCK” button for one second. When the locks cycle, that means the key fob has been successfully paired with your vehicle.
  6. To exit remote programming mode, simply turn the key to the “Off” position in the ignition. Perform the same process for any remaining key fob that needs to be programmed.
