Try twisting the cap off with a rubber band or cloth. Wrap a rubber band or cloth around the bottle cap multiple times until you can get a good grip on it. Twist the cap counterclockwise so to loosen it to see if it comes off. The added leverage from the rubber band may make the cap spin off of the bottle.
Twist It Out With a Key This is the next best method of opening a beer bottle, with the finest, sharpest keys securing the greatest results. Rest the key tooth underneath the grooves of the cap, and continue to pry and poke. Once the cap is loosened, keep twisting the key upward or turn the bottle itself.
