It's good news that replacing a key fob battery is among the simplest tasks you can tackle yourself. This is a simple fix that will save you money and time on a trip to the dealership or a locksmith.
The majority of key fobs require batteries that look like coins (CR2032 or similar) that you can find at any general store, home improvement center, or auto parts store. Key fobs typically have a slot that can accept these batteries, and opening the case to swap out batteries is fairly straightforward. Depending on the manufacturer, you may require an instrument such as a screwdriver to open the cover of the battery compartment.
If your key fob comes with clips that hold the batteries in place, gently remove them using your fingers or with non-metallic tools. Remove the battery that was in use and replace it with an alternative one, and be careful to note its orientation to ensure that you install it correctly. It is important to avoid touching the batteries' flat surfaces since finger marks can reduce their life.
Once the new battery is installed and the key fob is closed, close its case and test it by pushing the button to ensure it is working. If it doesn't work, you may need to open the case again and make sure whether the new battery has been properly installed.
