The battery inside the fob that powers it is responsible for the remote control function. The battery is a tiny, inexpensive part that needs to be replaced frequently to ensure the function of the device. There are many other reasons your key fob might not be functioning, aside from the battery. These issues could include physical damage, water exposure, or internal component failure. If your key fob's battery has stopped functioning, replace the battery.
First, ensure that you have the right size battery. Nearly all modern key fobs are powered by the standard CR2032 three-volt battery which is readily available in many stores. Most of these batteries are engraved with the size on one of the edges of the fob. You can determine the type of battery your vehicle requires by searching for the brand name.
Once you have the right battery take a moment to open your key fob and remove its existing battery. Take a photograph of the inside of your fob to ensure you put it back in the correct way. This simple step could help you avoid having to buy a new fob simply because you made an error while putting it together.

This key blade is located inside the key fob and allows you to unlock the door of the driver's seat of your car in the event that the remote control fails. To access the blade of the key, you must locate the notch in the middle of your fob. The notch is typically a circular shape that is concealed by the fob's plastic casing.

Modern car key fobs include several buttons that can perform various functions. For instance they can be used to lock and unlock the doors and activate the panic button, and even open the trunk. When a button on the fob is hit, it sends a radio code to a receiver inside the vehicle. Some fobs also come with a button that will start the engine, which is especially useful on cold winter mornings or hot summer days.
The buttons on a key fob can be reset by snapping it off and ensuring that they're not broken or stuck. The battery connector terminals on the key fob can get loose over time, despite the fact that they are not intended to be removed. Soldering is a method to reconnect the button contacts to the circuit board in case they have been disconnected. This will restore the fob's functionality.
