Battery
Switching the battery on your key fob is one of the most straightforward solutions. The device uses a small coin-shaped 3V battery (CR2032 or CR2025) which is typically easily found in general stores as well as home improvement shops and even some auto parts stores. Make sure to use a new battery -- old batteries are often not useful anymore and can cause damage to the circuit board.

Then, insert the screwdriver into the seam on all sides of the fob and raise a couple clips holding it in place. They can easily break so be cautious and work slowly.
After replacing the battery then reassemble the fob and test it to ensure that everything is functioning just as it should. If it isn't working after pressing the button several times, ensure that the contacts are clean. You can also try it using a spare key fob to determine whether the issue is limited to that particular key. If it isn't the case, there could be another reason for why your key fob isn't working. For example, it could be that the button is worn out. This could cause the button to function only occasionally, not all the time.
Interference
The key fob is powered by a small transmitter that sends out a short-range signal to a receiver in your car. Its goal is to enable your car to recognize the key fob, then open its doors when you are near it, and begin when you push the ignition button.
Interference can occasionally interfere with communication. If you charge your second-generation Apple Pencil while holding the fob (via iGeneration) it could block you from unlocking the vehicle.
