Battery
The simplest way to fix your key fob's battery is to replace it. The key fob is powered by a tiny coin-shaped 3V battery (CR2032 or CR2025) which is typically available in general stores or home improvement stores and even some auto parts stores. Make sure to use a new battery. Batteries that are old can damage the circuit boards and are no longer useful.
Start by removing the fob. It may be tight, but with the aid of a flat screwdriver, you will be able to break the two halves. Then, you can insert the screwdriver in the edges of the fob and lift a couple of clips holding it in place. They are very easy to break so proceed slowly and with care.
After replacing the battery take the fob apart and test it to see if everything is working just as it should. If it's not working you can try pressing the button a few times and ensuring that the contacts are clear. You could also try it with an additional key fob to determine whether the issue is specific to that particular key. If not, there could be another reason for the key fob to not work. It could be due to a worn-out button, as an example. This would only make the button work occasionally but not continuously.
