Easily Change Your Remote Garage/Gate Fob Battery!


Is your remote garage or gate fob not working as efficiently as it used to? You might need to replace the battery. In this guide, I’ll walk you through the steps to change the battery in your fob quickly and easily.

Replacing the battery can resolve issues like needing multiple presses to open your gate or garage. Let’s dive in and get your fob working like new again.

Tools You’ll Need

Before you start, gather the necessary tools. Here’s what you’ll need:

  • Precision screwdriver set
  • Flathead screwdriver
  • Two 2026 coin batteries

These tools make the process simple and efficient.

Identifying the Notch

The first step is to locate the notch on your fob. This notch is crucial for opening the fob without damaging it. Look around the edge of your fob to find a small indentation.

Once you find the notch, you’re ready to proceed.

Opening the Fob

To open the fob, take your flathead screwdriver. Insert it into the notch and gently wiggle it back and forth. Apply light pressure to pry open the fob.

Be careful not to use too much force. The plastic should come apart with minimal effort.

Removing the Old Batteries

Now that the fob is open, you’ll see the internal components, including the coin batteries. These are usually stacked together.

Slide the batteries out carefully. Remember the orientation: the positive side, with the lettering, should face you.

Keep this in mind for when you insert the new batteries.

Choosing the Right Batteries

It’s essential to use the correct batteries for your fob. For this guide, we’re using 2026 coin batteries.

Using the wrong size, like 1620, won’t work. Ensure you have the right type before proceeding.

Inserting the New Batteries

Take your new 2026 batteries. Stack them with the positive sides facing out, just like the old ones.

Slide them into the fob, ensuring they fit snugly.

Reassembling the Fob

Once the batteries are in place, align the two halves of the fob. Press them together until they snap back into place.

Double-check that the fob is securely closed.

Testing the Fob

With the new batteries installed, test your fob to ensure it works correctly. Try opening your garage or gate.

If it works on the first press, you’ve successfully replaced the batteries!

Tips for Maintaining Your Fob

To keep your fob in good condition, follow these tips:

  • Replace batteries annually

Regular maintenance can extend the life of your fob.

These tips can help troubleshoot most problems.
