Oftentimes, a faucet valve will become stuck because of a build-up of rust. To remedy this problem, you can try using penetrating oil to unstick the valve. First, you should remove the top screw from the faucet. You can also use a wire brush to remove rust from inside the valve. Then, you can apply penetrating oil to the valve using a narrow nozzle. Let it sit for a few minutes. Afterward, you should use a dry rag to grip the handle of the faucet and a hammer to turn it.

If you are unable to unscrew the faucet handle, it may be due to corrosion. If this is the case, you can unscrew the cap of the faucet so that you can see the valve clearly.
