A dead key fob battery can catch anyone off guard. But don’t stress out! Fixing a dead key fob battery is usually simple and quick. Let’s see what happens when your key fob battery dies, what to do about it, and when is the time to contact a professional auto locksmith.
Key fobs have become an important part of modern car ownership. They save you the inconvenience of using a mechanical key every time you need to lock, unlock or start your car. Some fobs allow you to even open trunks or hatches with a single click.
While key fobs make daily driving more convenient, this also means you’re depending on them. If anything causes the key fob to stop working, it becomes a hassle. Knowing how to replace the key fob battery and recognizing when it’s time to get professional help can save you from unexpected frustrations.
How Does a Key Fob Work?
Understanding how a key fob works will allow us to know how to repair one. A key fob is an electronic device used to control some functions of your car remotely. It typically operates on radio signals. When you press any button on the key fob, it sends a unique signal to your car. This signal is coded in a way that only your car’s receiver can understand it. Your car performs the required action after receiving the signal, which can be unlocking the doors or starting the engine.
Without a functioning battery, the fob can’t send these signals, leaving you unable to use the remote features.
What Happens If My Key Fob Battery Dies?
The battery powers the fob’s transmitter, which sends signals to your car. Without power, the fob can’t communicate with your vehicle. A dead battery means you won’t be able to use any remote functions like unlocking your car. It can be really frustrating but don’t worry. It is a common problem and might get resolved by just a battery replacement.
How Do You Replace a Dead Key Fob Battery?
If your key fob is not working, the battery might be dead and might need to be replaced. Don’t worry, it’s not a big task and we’ll guide you step-by-step:
-
Buy the Battery
You should know the correct battery size for your fob before buying a new one. The correct battery size might be printed on the old batteries. You can also look at the back of the key fob for the battery size. If you still are unable to find the correct battery size, the store where you’re buying batteries might be able to help you. The most common key fob batteries are CR2032 and CR2025. Before purchasing new batteries, be sure they are the correct type.
After you have purchased the batteries, we can proceed with the replacement.
-
Open the Key Fob
Look for a small seam along the edge of the fob. Insert a flathead screwdriver or a coin into this seam and gently pry the fob open. If you see a screw or a latch, you’ll need to remove it before you can open the fob.
-
Remove the Old Battery
Once the fob is open, locate the battery. If there is any clip to hold the battery in place, take it out first. Now, remove the old battery carefully, noting the battery orientation. You might need to use a screwdriver.
-
Insert the New Battery
Now, Place the new battery in the battery slot. Make sure to orient it correctly.
-
Reassemble the Fob:
After inserting the new battery, restore the fob to its original condition. Put any screws you opened back in place.
-
Test the Fob:
After reassembling, test the key fob by pressing any buttons and see if the required function is performed. If it works correctly, you’ve successfully replaced the battery! If not, this is the time you might consider contacting a professional auto locksmith to handle the situation.

What Kills Key Fob Battery?
The key fob battery is built to last about three to five years. But if you notice your key fob battery gets drained much faster, these factors that might be at play here:
-
Extreme Temperatures
Battery performances are always affected by the temperature. It’s because batteries operate on chemical reactions. The rate of these reactions changes with temperature. While you can’t change the weather, you should save the fob from direct exposure to extreme temperatures.
-
Battery Quality
When we said batteries should last about three to five years, we meant good ones. You should always buy good-quality battery for your key fob. Good battery not only lasts longer but it also has a role in your key fob’s life. Bad-quality batteries can cause the key fob to malfunction. You certainly want to avoid that.
-
Electronic Interference
Interference in key fob signals from gadgets like your phone can weaken the signal. This means the key fob battery gets more drained to perform the same action. This might seem like a trivial thing but it does add up in the long-term.
