In this guide, we’ll walk you through the steps to replace the battery and ensure your keyless entry remote functions optimally.

Key Takeaways:

Determine the Battery Type

Before you can change the battery in your Honda key fob, you need to determine the battery type. This will ensure that you purchase the correct replacement battery.

To find out the battery type, start by flipping over your keyless entry remote and checking the back for any writing. The battery type may be clearly labeled on the back of the fob. However, if the writing is illegible or not present, you can still determine the battery type by inspecting the existing battery inside the key fob.

Open the key fob by following the instructions in the previous section. Once the key fob is open, take a close look at the battery. The battery type is often printed on the battery itself. Look for any numbers or letters that indicate the battery type. Common battery types used in Honda key fobs include CR2032 and CR2025.

Once you have determined the battery type, you can purchase a replacement battery that matches the specifications. It’s important to use the correct battery type to ensure optimal performance and longevity of your Honda key fob.

Open the Honda Key Fob

Now that you have determined the battery type used in your Honda key fob, it’s time to open the fob to access the battery compartment. Opening the key fob is a crucial step in the battery replacement process. Here’s how you can do it:

1. First, check if your keyless entry remote has a screw on the back. If yes, you will need a jeweler’s screwdriver to remove it carefully. Set the screw aside in a safe place.
2. Next, take a small flathead screwdriver and insert it gently into the seam between the two halves of the key fob. Apply gentle pressure and slowly pry the halves apart. Be cautious not to use excessive force to avoid damaging the key fob.
3. As the two halves separate, you may hear a slight clicking sound. This is normal and indicates that the key fob is being successfully opened.

Once the key fob is open, you will have access to the battery compartment. Now you can proceed to remove the old battery and replace it with a new one to restore the functionality of your Honda keyless entry remote.

Before moving on to the next step, make sure to keep any screws or other small parts in a safe place to avoid losing them during the battery replacement process.

Remove the Dead Battery

When replacing the battery in your Honda key fob, the first step is to remove the dead battery. Take note of the positive and negative sides of the battery while removing it. This is important because it ensures that you install the new battery correctly. Make sure to avoid touching the battery terminals with your fingers as this can lead to potential corrosion.

If you’re unsure about which side is positive or negative, look for markings on the old battery. It is usually indicated by a plus (+) and a minus (-) sign. Align your new battery accordingly to ensure proper functionality of the key fob.

Removing the dead battery is a straightforward process. Simply use a small flathead screwdriver or your fingers to carefully pry out the old battery from its slot. Take your time and work gently to avoid damaging any other components of the key fob.
