North Carolina Locksmith Practice Exam

A cylindrical lockset is characterized by its design where the latch mechanism is installed through a cross-bore in the door, creating a straightforward and compact structure. This design typically features a cylinder located on both sides of the door, allowing for easy operation whether from the inside or outside, usually involving a turn knob or lever on one side and a key cylinder on the other. The strength and security this provides makes it a popular choice for residential and commercial applications.

The other options describe different types of locks or features that do not accurately represent a cylindrical lockset. For example, having multiple bolts is more representative of multi-point locking systems rather than the singular latch mechanism that defines a cylindrical lockset. Likewise, deadbolts are separate entities that provide a specific higher level of security for external doors. Lastly, a notable key-pairing system does not pertain to the defining characteristics of cylindrical locksets, which primarily focus on their functional design and installation method.
