How to Open Your Honda Key Fob

Let’s start with the basics of how to open your Honda key fob. The plastic casing of the key fob also contains a metal key for emergencies, as well as your Honda key fob battery. Taking the casing apart isn’t too difficult, so here are the steps that you’ll need to follow:

• Look at the casing and locate the sliding button that releases the metal key.
• Press the button and remove the key. 
• Place the edge of the metal key into the slot at the top of the key fob.
• Twist the key gently to pry the two pieces apart. 
• Your key fob should now be in two pieces.

How to Change the Battery in Your Honda Key Fob

Next, let’s talk about how to change the battery in your Honda key fob. Before you take out your old Honda key fob battery, be sure to pick up a new one at the parts department. The most common battery type is a flat circular 3-volt battery, like a CR2025. Our team can help you locate the right type, or you can always check your owner’s manual. Then, go through this quick process:

• Hold the key fob steady and locate the battery.
• Pop out the old battery. You can use a flathead screwdriver if it is stuck.
• Replace the old battery with a new one. Try to minimize handling to prevent corrosion.
• Line up the front and back pieces of the key fob casing and snap back together. 
• Replace the metal key if you haven’t already.

How to Program Your Honda Key

Finally, let’s go over how to program your Honda key like a pro. Now that you have a fresh Honda key fob battery, your key fob should work like a charm. Here are the steps to get it going once again:

• Get in the driver’s seat with your key fob and shut all the doors.

• Release the button and turn to the “Off” position.
• Repeat this process two more times.
