Movie rule #28810 - Shooting a lock will automatically open or close a lock, depending on what's required.
You ever notice how in action movies, whenever someone shoots a lock, it does exactly what they need it to? This is especially true in science-fiction movies, which can be vague about exactly how the lock works. How many movies have you seen where the hero is escaping from a horde of enemy soldiers, runs through a door, then turns and blasts the door's lock with a laser gun, then we cut to the soldiers on the other side, banging on the door that no longer opens. Or cut to the other movie, where the hero has to get through a door, grabs his laser gun and blasts the lock, and the door obediently opens. You'd think the lock's designer would take shooting it into account and make it blaster-proof. When was the last time you saw a movie where the hero tried to open a door, then blasted the lock, and the heroine goes, "Great, you just melted the lock! Now we're really trapped in here!" I'd like to see that.
