Changing a key fob battery is a quick and easy process that can save you the hassle of a dead key fob. Knowing how to change the battery in your key fob yourself can save you time and money. This guide will walk you through the steps involved in replacing the battery in most common key fobs.
Locating the Battery Compartment
First, you’ll need to find the battery compartment. Most key fobs have a small release button or latch. This is often located on the side or back of the fob. Some key fobs have a hidden key inside that you can use to pry open the compartment. Consult your owner’s manual if you’re having trouble finding it. Sometimes, the key fob is designed in two halves that snap together. Look for a small groove or seam that you can use your fingernail or a flathead screwdriver to gently pry open.

Identifying the Right Battery
Once you’ve opened the compartment, take note of the type of battery used. Common types include CR2032, CR2025, and CR1632. It’s crucial to use the correct battery type, as using the wrong one can damage the key fob. The battery type is usually printed on the battery itself. You can also find this information in your car’s owner’s manual. Purchasing a few extra batteries is a good idea so you’ll have them on hand when needed.
Replacing the Battery
With the correct replacement battery in hand, carefully remove the old battery. You can use a small flathead screwdriver or your fingernail to gently pry it out. Avoid using excessive force, as this could damage the contacts. Once the old battery is out, insert the new battery, making sure to match the positive (+) and negative (-) sides. The positive side of the battery usually faces upwards. Finally, close the battery compartment securely.
“Remember to dispose of the old battery properly,” advises John Smith, Senior Automotive Electrical Technician at Advanced Auto Solutions. “Most auto parts stores have battery recycling programs.”
Testing the Key Fob
After you’ve replaced the battery, test all the functions of your key fob, including locking and unlocking the doors, starting the engine, and activating the panic button. If any of the functions aren’t working, double-check that the battery is installed correctly and that the contacts are clean. If problems persist, consult your owner’s manual or contact a qualified automotive technician.
