Cylindrical Locks

Sometimes called bored locks, cylindrical locks are sturdier than tubular locks.  The latchbolt assembly interlocks with one side of the lock chassis, making it easier to install, replace and rekey.  Cylindrical locks are considered more secure than tubular locks, and the majority of the locks in the US today are cylindrical locks.

Mortise Locks

Mortise locks are considered even more secure than cylindrical locks.  They require a pocket to be cut into the door and consist of a lever mechanism.  They are stronger and more heavy duty than cylindrical locks, making them ideal for use in hospitals and schools.  Additionally, mortise locks are heavy enough to support ornate and solid cast knobs and levers.  They accept a wide variety of cylinders and accessories, allowing for architectural conformity with locks and door hardware already on site.

Tubular/Interconnect Locks

Tubular locks have a center spindle assembly that extends through the center of the lock body and latch, allowing for retraction of the latch when the lever or knob are rotated.  While these type of locks are very common on interior doors and in residential applications, they are considered the least secure lock type.
 
Interconnected door locks have an internal mechanism that retracts the deadbolt when the inside knob or lever is turned to open the door. This type of lock is required by some municipalities for certain applications like group or retirement homes.

Deadbolt Locks

Also called a deadlocks, deadbolts are considered more secure than all of the spring-latch locks.  Deadbolts are available with a single cylinder or a double cylinder.  The single cylinder deadbolt operates by a key on the outside and a thumbturn on the inside.  A double cylinder deadbolt requires a key for unlocking on both sides of the door.
