How to Change the Battery in a Key Fob
If you own a car with a keyless entry system, you probably have a key fob. The key fob allows you to remotely lock, unlock, and start your car. However, when the battery in your key fob dies, you’ll need to replace it. Here’s how to change the battery in a key fob.
Step 1: Find the Battery
First, you need to locate the battery compartment in your key fob. The exact location varies depending on the make and model of your car, but it’s usually on the back of the key fob. Look for a small indentation or groove where you can pry open the compartment.
Step 2: Open the Battery Compartment
Once you’ve located the battery compartment, use a small flathead screwdriver or a coin to pry it open. Be careful not to damage the key fob or the battery compartment.
Step 3: Remove the Old Battery
Take out the old battery and dispose of it properly. Make sure you remember which side of the battery was facing up so you can install the new battery correctly.
Step 4: Install the New Battery
Insert the new battery into the compartment, making sure you place it in the correct orientation. The positive (+) side should be facing up in most cases, but check the instructions that came with your key fob to be sure.
Step 5: Close the Battery Compartment
Snap the battery compartment shut. You should hear a click or feel a small resistance when it’s securely closed.
Step 6: Test the Key Fob
Test the key fob to make sure it’s working properly. Aim the fob at your car and press the unlock button. The car should respond by unlocking the doors. If it doesn’t work, try pressing the button again or check the battery orientation.
Changing the battery in a key fob is quick and easy. With these simple steps, you can ensure that your key fob continues to work properly and allows you to access your car remotely. If you’re unsure about how to change the battery in your key fob or have any questions, consult your car’s owner’s manual or contact your dealer for assistance.
