How to Open Honda Key Fob and Replace the Battery

Although your key fob might seem like it’s sealed shut to some Brookfield drivers, there is a way on how to open Honda key fob correctly. Use the following steps:

  • Locate the button to release the metal key inside the fob. Slide that button open and pull the key out. 
  • Carefully place the edge of the key into the slot at the top of the key fob. Wedge the key and lightly twist, the back of the key fob should pop off. 

This is the way the key fob was designed to be opened; it’s a tried and tested way so you don’t break or damage your key fob when you’re trying to find out how to change the battery. Now that you have it open, you can change the battery in Honda key fob.

  • Hold your thumb right above where the battery is located.
  • Using your other hand, carefully pry the dead battery out and replace it with a fresh one.
  • Line the back of the key fob up with the front half, gently press the pieces back together. Once secured, you will hear a snap.

The final step is to know how to program your Honda key fob battery. This step ensures that your key fob is working properly and it will work fine the next time you use it. Knowing how to program the Honda key fob is the easiest step. Use the following steps to properly program your key fob:

  1. Enter the cabin, securely shut all doors, and have your key and fobs to be programmed ready. 
  2. Insert the key and turn to the “On” position. Press and hold the “LOCK” button for one second. 
  3. Release the button and turn the key to the “Off” position. Repeat this process twice more.
  4. Turn the key to the “On” position and hold the “LOCK” button on the key fob for one second. Wait for the doors to lock and unlock automatically. Once the locks have cycled, your vehicle is in remote programming mode.
  5. Once again hold the “LOCK” button for one second. Once the locks cycle, the key fob has been successfully paired with your vehicle. Repeat the process with any additional fobs that need programming.
