Ever found yourself staring at your car, keys in hand, only to realize your key fob is dead?

Knowing how to change your key fob battery is a simple task that can save you time and stress. This guide will walk you through the process, step-by-step, so you can get your key fob back in working order in no time.
Identifying Your Key Fob Type
The first step is to identify the type of key fob you have. Key fobs come in various designs, and the battery replacement process can differ slightly depending on the model. Some common types include:
- Flip-out key fobs: These have a physical key that flips out from the fob.
- Button-style key fobs: These have buttons on the surface for locking, unlocking, and other functions.
- Smart key fobs: These are more advanced and often have a keyless entry feature.
Gathering Your Tools
Once you know what type of key fob you have, gather the following tools:
- A small flathead screwdriver or a coin.
- A new battery. The type of battery will be specified in your car’s owner’s manual or on the back of the key fob. Common types include CR2032, CR2025, or CR1620.
- Optional: Tweezers or a small pair of pliers (for some models).
Locating the Battery Compartment
The battery compartment is usually located on the back of the key fob. It may be hidden under a small cover or simply accessible by pressing a button or tab.
- Flip-out key fobs: The battery compartment is often found on the back of the key fob, near the hinge of the flip-out key.
- Button-style key fobs: The battery compartment may be located on the back or on one of the sides.
- Smart key fobs: These key fobs may have a more complex battery replacement process, so refer to your car’s owner’s manual for specific instructions.
Removing the Old Battery
Once you’ve located the battery compartment, use your screwdriver or coin to pry open the cover or release the latch. The old battery should be easily accessible. Carefully remove the battery, being mindful of its polarity (the positive and negative sides).
Installing the New Battery
Take your new battery and align it with the positive and negative terminals inside the battery compartment. The positive side of the battery should be facing the spring inside the compartment. Gently press the new battery into place.
Reassembling the Key Fob
Once the new battery is securely installed, close the battery compartment. If there’s a latch, make sure it clicks into place. For some models, you might need to press the cover or latch firmly to ensure it’s properly closed.
Testing Your Key Fob
Now, it’s time to test your key fob. Press the buttons to check if they’re working. You should hear the familiar “beep” sound and see the lights illuminating. If everything is working correctly, you’re all set!
