Step-by-Step Guide

Step 1: Remove the Phillips Screw

First, flip your key fob over. You’ll notice a small Phillips screw on the back. Use a precision screwdriver to remove this screw. It might be tight, especially if it’s the first time you’re removing it.

Once the screw is removed, set it aside in a safe place. This will free up the back cover of the key fob.

Step 2: Open the Key Fob Shell

With the screw removed, use the largest flathead screwdriver in your precision set. Locate the notch at the base of the key fob. Insert the flathead screwdriver into the notch and twist gently.

This action will pop off the shell of the key fob, revealing the internal section. Carefully pull out the internal section and set the outer shell aside.

Step 3: Access the Battery Compartment

Next, locate another notch in the upper right corner of the internal section. Use the same flathead screwdriver to twist and separate the internal piece into two parts.

This will give you access to the battery compartment. You should now see the CR1616 battery that needs to be replaced.

Step 4: Remove the Old Battery

Using the flathead screwdriver, gently pop out the old CR1616 battery. Be careful not to damage the battery compartment while doing this.

Once the old battery is removed, dispose of it properly. It’s a good idea to have the new battery ready to install immediately.

Step 5: Install the New Battery

Take the new CR1616 battery and ensure the positive side is facing down. Carefully pop the new battery into place.

Make sure the battery is securely seated in the compartment. There should be no overhangs or loose parts.

Step 6: Reassemble the Internal Section

With the new battery installed, snap the internal section back together. Ensure everything is aligned correctly before snapping it into place.

If your key fob has a light, check to make sure it lights up. This indicates that the battery installation was successful.

Step 7: Reassemble the Key Fob Shell

Now, take the internal section and place it back into the outer shell. There is a lip at the top of the shell. Align this lip first to make snapping the fob back together easier.

Once the shell is aligned, snap it into place. Ensure all edges are securely closed.

Step 8: Replace the Phillips Screw

Finally, take the small Phillips screw you removed earlier and screw it back into the key fob. This will secure the outer shell and complete the reassembly process.

Congratulations! You’ve successfully replaced the battery in your Honda Odyssey key fob.
