One type can be locked from the inside by simply pressing or turning a small button and can be unlocked with the use of a key at the opposite side of the knob. Other types lock from both inside and outside with the use of a key; while others can be locked or unlocked on both sides.

2.)    Deadbolt Lock:

The double cylinder, on the other hand, can be locked or unlocked using a single key from both sides.
