Is your car key fob suddenly not working? Before you rush to the dealership, the solution might be simpler than you think – replacing the battery. As a car expert at keyfobx.com, I’m here to guide you through the easy steps on how to remove the battery from your key fob and get you back on the road quickly. Changing your key fob battery is a straightforward task you can do at home with just a few basic tools. Let’s dive in and learn how to do it.
First, let’s gather everything you’ll need to get the job done efficiently.
Tools You’ll Need
Before you start, make sure you have these items ready:
- Small Screwdriver: A flathead or Phillips head screwdriver, depending on your key fob model, will be necessary to gently pry open the casing.
- New Battery: Identify the correct type of battery for your key fob. You can usually find this information in your car’s manual or by checking the old battery once you’ve opened the fob. Common types include CR2032, CR2025, and CR1620.
- Your Key Fob: Of course, you can’t change the battery without the key fob itself!
Now that you have your tools, let’s move on to the step-by-step guide for removing the battery.
Step-by-Step Guide to Remove Key Fob Battery
Follow these simple steps to safely open your key fob and access the battery compartment.
Step 1: Detach the Key
Most key fobs contain a physical, detachable key for manual entry into your vehicle. Locate the release button or latch on your key fob. This is often a small button, usually silver or gray, that contrasts with the main fob color. Press or slide this release to detach the mechanical key.

Once the key is detached, you’ll see the next access point to open the fob casing.
Step 2: Open the Key Fob Casing
With the mechanical key removed, you will usually find a small slot or seam revealed on the key fob. This is where you will insert your small screwdriver to gently pry the two halves of the fob casing apart.

Carefully insert the tip of your screwdriver into the slot and gently twist or lever to separate the casing. Work your way around the seam, applying gentle pressure until the two halves of the key fob come apart. Be patient, especially if it’s the first time opening the fob, as the latches can be quite tight.

Step 3: Battery Removal and Replacement
Once the key fob is open, you will see the battery. Before removing the old battery, take a moment to note its orientation – specifically, which side is facing up (+ or -). This is crucial to ensure the new battery is installed correctly. Gently remove the old battery. You might be able to pry it out with your finger or the tip of the screwdriver if it’s snug. Insert the new battery, making sure it is facing the correct way, matching the orientation you noted earlier.

Step 4: Reassemble the Key Fob
With the new battery in place, carefully align the two halves of the key fob casing and press them firmly back together. You should hear a click or snapping sound as the latches re-engage, indicating that the fob is securely closed. Finally, slide the mechanical key back into its slot until it clicks into place.
Test Your Key Fob
After reassembling your key fob, test it to ensure it’s working correctly. Press the lock and unlock buttons to see if your car responds. If everything works as expected, you’ve successfully replaced your key fob battery!
