How to Open the Honda Key Fob

If you’re wondering how to open your Honda key fob, keep reading. It’s a simple process.

  • Locate the button on your key fob that will release the hidden metal key inside the fob. Press or slide that button open and pull the key out. 
  • Place the edge of the key, or another flat tool, like a screwdriver, into the slot at the top of the key fob. Twist it back and forth gently, and the key fob casing should pop open. 

How to Replace Honda Key Battery

Once your Honda key fob casing is open, be careful with it, so it doesn’t fall apart. Also, note the position of the old battery and how it is situated in the Honda key fob. Follow these tips from the auto pros at Harvest Honda Yakima to keep your fob intact while replacing your Honda key battery:

  • Hold your thumb right above where the battery is.
  • Using your other hand, gently pry the old battery out and replace it with a new one in the same position.
  • Line up the back of the key fob casing with the front half and carefully press the pieces back together. Once properly secured, you should hear it snap together.

  1. Climb into the cabin and securely shut all the doors.
  2. Insert your key and turn it to the “On” position. Press and hold the “LOCK” button down for one second.
