As you rush off to work, you click your car’s key fob to unlock the door…but nothing happens. The battery in your fob is dead, so how do you replace it? Luckily, it’s super quick and easy to change out your old key fob battery. We’ll show you how to open your key fob, find the right battery, and insert it to get your fob back to working order. If you’re ready to learn how, read on!
Why You Might Need to Change Your Key Fob Battery
Your car key fob is a small but essential component that enables the smooth operation of your vehicle. However, like any battery-powered device, the key fob's battery can wear out over time. Typically, fob batteries last anywhere from two to five years, but if you notice your fob becoming less responsive or not working at all, it’s time for a battery replacement.
Things You Should Know Before You Start
Step-by-Step Guide to Replacing Your Key Fob Battery
1. Open the Key Fob
Move the Key if Necessary: Some key fobs store a mechanical key inside. If your fob has this feature, slide or swing the key out of the way before proceeding.
Unscrew the Fob (If Applicable): Older car models may have a small screw holding the fob together. If your fob has a screw, use a small Phillips head screwdriver to remove it. Set the screw aside in a safe place.
Pry Open the Fob: Look for a seam or notch where the two halves of the fob come together. Use a small flathead screwdriver or coin to gently pry the fob open. Be cautious not to apply too much force to avoid damaging the casing.
2. Replace the Battery
Remove the Old Battery: The battery is usually a small, silver coin-cell located in the center of the fob. Use your tool to carefully lift the battery out of its compartment. If there are clips holding the battery in place, lift them gently to avoid breaking them.
Insert the New Battery: Check the orientation of the old battery to ensure the new one is placed correctly. Typically, the positive side (+) should face up. Slide the new battery into place and press down to secure it.
3. Reassemble and Test the Fob
Snap the Fob Closed: Align the two halves of the fob and press them together until you hear a click. If your fob had a screw, reinsert it and tighten it securely.
Test the Fob: Point the fob at your car and press a button to ensure it’s working correctly. If it doesn’t work, double-check the battery orientation and try again.
