Is your car key fob acting up? Don’t worry, you probably just need a new battery! Many people think a dead key fob means a trip to the dealership and an expensive replacement. But in most cases, changing the battery yourself is a simple task you can do at home in just a few minutes. This guide will walk you through the steps on how to change the battery on your key fob, saving you time and money.
First, you’ll need to gather a few basic tools. For most key fobs, you’ll only need a small flathead screwdriver and a new battery. The type of battery varies depending on your car’s make and model, but common types include CR2032, CR2025, or CR1632. You can usually find the battery type listed in your owner’s manual or by checking the old battery once you open the fob. Having these simple items ready will make the process smooth and efficient.
Let’s get started with opening your key fob. The first step is to locate and remove the mechanical key. Most key fobs have a hidden, detachable key that slides out. Look for a button or release catch, often located on the side or bottom of the fob. Press or slide this release while gently pulling the key portion away from the fob body.
With the mechanical key removed, you’ll see an opening or seam on the key fob. This is where you’ll need to gently pry the fob open to access the battery compartment. Take your small flathead screwdriver and carefully insert the tip into the seam. Apply gentle pressure and twist the screwdriver to separate the two halves of the key fob. Be patient and work your way around the seam, gently prying until the fob comes apart. Some fobs may be a bit tight, especially the first time you open them.
Once the key fob is open, you’ll see the battery. Before removing the old battery, take a close look at how it’s positioned. Note the positive (+) and negative (-) sides. This is important to ensure you install the new battery correctly. Carefully remove the old battery. You might be able to use your fingertip or the small screwdriver to gently pry it out. Now, take your new battery and install it in the same orientation as the old one. Make sure the positive and negative sides are facing the correct way.
With the new battery in place, it’s time to reassemble your key fob. Carefully align the two halves of the fob and press them firmly together until they snap back into place. You should hear a click, indicating that the fob is securely closed. Finally, slide the mechanical key back into the fob until it locks in position.
To finish up, test your key fob to make sure it’s working properly. Press the lock and unlock buttons to confirm that your car responds.
