Honda key fobs typically use a flat, circular 3-volt battery. However, it’s important to double check which Honda key battery you should use before you replace the old one.

Flat, circular 3-volt batteries can generally be found at local stores all across the country. To be extra safe, it’s not a bad idea to ask your local Honda parts department to get a genuine Honda key battery replacement.

  • Find the button to release a metal key inside the fob, slide it open, then pull out the key.
  • Place the edge of the key carefully into the slot at the top of your Honda key fob.
  • Wedge the key into the slot and lightly twist it until the back of the key fob pops off.

How to Replace Your Honda Key Fob Battery

While getting the Honda key fob open is easy enough, you don’t want to just pull the battery out once the fob’s open as that might also pull out essential components, leading you to have to replace the entire key fob. Follow these pro tips to make sure everything stays intact while you replace the battery:

  • Find where the battery is located, then hold your thumb right above it.
  • Use your other hand to carefully pry the dead battery out before replacing it with the new one.
  • Line up the back of your Honda key fob with the front half, then softly press them back together until you hear the snap that indicates they’re properly secured.

How to Program Your Honda Key Fob

After you’ve replaced the Honda key fob battery, you may have to program the fob itself again. Fortunately, programming the key fob only takes a few simple steps to complete:

  • Get into your Honda, securely shut all the doors, then take out the key fob that needs to be programmed.
  • Insert your key and turn it to the On position, then press and hold the LOCK button on your key fob for one second.
  • After releasing the LOCK button, turn your key to the Off position, then repeat the process twice.
  • Turn your key to the On position and hold the LOCK button for one second once again, waiting for the doors to lock and unlock automatically. Once the locks have cycled, your vehicle will have gone into remote programming mode.
  • Once more hold the LOCK button for a second. Once the locks cycle, your key fob will have been successfully paired with your vehicle.
  • Repeat the process with any additional fobs that need programming, then exit programming mode by turning the key to the Off position.
