The single cylinder lock could be opened by a key on one side of the door only, while the double cylinder lock could be opened by a key on both sides (in this case, you wouldn’t need a twist knob anymore). Other modern locks include magnetic key locks, which operate by magnet and are thereby impossible to pick; biometric locks, which use fingerprint recognition systems and heavy duty bolts for heightened security.
