Check the Battery
The remote control is powered by the battery that is in a key fob. The battery is a small piece of equipment that has to be replaced frequently in order to maintain the functionality of the key fob. But, aside from the battery, there could be other reasons why your key fob may not be working. Physical damage, water exposure or internal component failure could be the reason. If your key fob has stopped working, replace the battery.

If it reads lower than that, it could indicate that the battery is on its last legs and needs to be replaced immediately.
Check the Buttons

Many modern-day car key fobs have several buttons that can be used for various purposes, such as locking and unlocking doors and activating the panic button and opening the trunk.
