Knob Locks

Additionally common door locks, these serve as the majority of home locks' primary security measure. Instead of the door, their lock cylinder is located in the knob. However, because they are less secure than deadbolts, internal doors can use them.

Handle Locks

Barrel Bolt and Chain Locks

Security locks with barrel bolts and chains work by sliding a cylinder or fastening a chain to a jam attached to the door. To keep kids from opening the doors, these locks are typically mounted at their tops. When the owners are there, they work best to prevent intruders from entering a house.
