Is your Honda key fob displaying a low battery warning on your dashboard? Don’t worry, replacing the battery in your Honda key fob is a straightforward process you can easily do yourself. This guide will walk you through each step, ensuring you can quickly and efficiently get the battery out of your Honda key fob and get back on the road with confidence.
Before diving in, you’ll want to gather a couple of essential items. For this task, you will need a new CR2032 battery – the standard for most Honda key fobs – and a small flathead screwdriver. Having these tools at hand will make the process seamless.

Now, let’s get started with the step-by-step process to remove the battery from your Honda key fob:
Step 1: Remove the Emergency Key
The first step is to remove the mechanical emergency key from your Honda key fob. Locate the small release switch, usually a button or slider, on the fob. Slide or press this switch to release the emergency key. Pull the key out of the fob and set it aside. This key is a crucial backup, allowing you to manually unlock your car door should your car battery or key fob battery fail completely.

Step 2: Separate the Key Fob Casing
With the emergency key removed, you now need to open the key fob casing to access the battery. Inspect the sides of your key fob where the emergency key was housed. You’ll notice small tabs or slots along the seam. While the owner’s manual might suggest using a coin, a handy alternative is to use the emergency key itself.

Insert the tip of your emergency key or a small coin into the slot between the tabs. Gently twist the key or coin. This should start to separate the two halves of the key fob. Work your way around the seam, gently prying until the casing splits open. Avoid using excessive force to prevent damaging the plastic clips.

Step 3: Access and Remove the Old Battery
Once the key fob is open, you’ll see the circuit board and the CR2032 battery. The battery is typically held in place by small metal clips. This is where your small flathead screwdriver comes in handy.

Carefully insert the tip of the screwdriver under the edge of the battery, being mindful not to damage the circuit board. Gently pry upwards to lift the battery out of its housing. It’s best to lay the fob flat on a table during this step. This prevents the circuit board from lifting up and potentially dislodging the buttons on the other side.

Step 4: Install the New Battery
Take your new CR2032 battery and ensure it’s oriented correctly. Usually, the positive (+) side of the battery faces upwards. Slide one edge of the new battery under the retaining clips, and then press down on the other side until it snaps securely into place.
Step 5: Reassemble the Key Fob
Now that the new battery is in place, it’s time to reassemble your Honda key fob. Carefully align the two halves of the fob casing. Press them firmly together until they snap closed. You might need to apply a bit more pressure than expected. A helpful tip for easier reassembly is to first align and squeeze the end opposite to the emergency key slot, and then snap the key slot end closed.

- Battery Type: Always use a CR2032 battery for your Honda key fob. These batteries are widely available and have a long shelf life, making it wise to buy a multipack for future replacements.
