What do class 4 cylinder locks offer?

Security class 4 means the lock cylinder can withstand even an experienced thief using tools like a lock-picking hammer, axe, chisels, or a portable cordless drill. With these tools, a thief can expand the ways they attack the cylinder lock. In this case, they are not concerned about the noise created by these methods.
