Battery
The most simple way to fix the battery on your key fob is to replace it. The key fob is powered by a tiny coin-shaped 3V battery (CR2032 or CR2025) that is generally available in general stores as well as home improvement shops and some auto parts stores. Use a new battery. Old batteries can cause damage to the circuit boards and become less useful.

After that, slide the screwdriver into the edges of the fob, and then lift the clips holding it in place. They can easily break, so be careful and work slowly.

It is also possible to test it using another key fob to determine whether the issue is specific to the specific key. If not it could be another reason for why the key fob isn't working. For example, it could be that the button is worn out. This will only make the button work infrequently and not all the time.
Interference
The key fob has an insignificant transmitter to send an audio signal that is short-range to a receiver within your car. Its goal is to enable your car to recognize the key fob, unlock its doors as you approach it, and begin when you press the ignition button.
The issue is that interference can interfere with this communication. For example, if you have your second-generation Apple Pencil charged while you're holding the fob, it might hinder you from unlocking your car (via iGeneration).
Other electronic devices that use the same frequency as the fob can interfere with the signal. Garage door openers, or tire pressure monitoring devices can also be affected. It is even possible that an RF transmitter in your home may be interfering with the fob's signal although this would be difficult to identify without an expert test.
It's also possible that the key fob just needs to be reset. This process requires the transmitter on your fob to be recognized by the receiver inside your
mini car key cover and a specific code is used for each pairing. Fobs are typically changed when they're removed or replaced, or when you purchase a replacement or, in certain cases it's when a battery has been changed. To reprogram a fob, follow the steps in the owner's guideline or ask a dealer for assistance.

The fob should also not be exposed to water, or soapy residue. Water is a common cause of corrosion, which can cause interference with the circuit board. If this is the case you'll need to wash the board with isopropyl, or an electronic cleaner prior to installing a new battery.
It is a good idea to test the function of the fob prior to operating the vehicle. Utilizing a voltmeter to check the voltage of the
