A lockset is a complete door locking mechanism including the lock cylinder, latch, strike plate, and hardware components that provide security and access control for doors in residential and commercial construction. This integrated hardware system combines all necessary components for door operation and security in a single coordinated unit. Locksets are essential building components that provide both functional door operation and security protection for buildings and occupants.

The primary purposes include providing secure access control for doors, enabling convenient door operation and locking, meeting building security and safety requirements, supporting different levels of access control, integrating with building design and aesthetics, ensuring reliable long-term door operation, and complying with accessibility and code requirements.

Types and classifications involve cylindrical locksets, mortise locksets, deadbolt locks, and electronic locksets for different security levels and applications.

Fun Fact: The first pin tumbler lock was invented by Linus Yale Jr. in 1861! Modern locksets can have over 100,000 different key combinations. Grade 1 locksets must withstand 800,000 cycles of operation – equivalent to about 25 years of normal use!
