Welcome to Tyeign! We select all kinds of high-quality kitchen supplies and everyday tools and home decorations for you.

Solid Metal Durability: The knob and rosette are cast from zinc alloy and finished with electroplated matte black that resists scratches, tarnish and fingerprints, maintaining a sleek modern appearance through years of daily use. The robust all metal construction exceeds ANSI Grade 3 standards for residential security, providing reliable performance for front entries, bedroom privacy or office interior doors without the wobble or cracking common in plastic hardware.
Universal Fit Installation: Adjustable 60 to 70 mm (2.36 to 2.76 in) backset and 30 to 50 mm (1.18 to 1.97 in) door thickness compatibility mean this lock replaces most existing knob sets without drilling new holes or chiseling the frame. Pre installed screws and illustrated instructions guide quick 10 minute installation with only a Phillips screwdriver, making it an ideal weekend upgrade for new homeowners or rental property improvements that demand professional results without hiring a locksmith.
Secure Keyed Entry: Each set includes three precision cut brass keys that operate smoothly without sticking, and the pin tumbler cylinder provides over 10,000 key combinations to deter picking or bumping. The exterior knob locks with a simple turn of the interior thumb turn, giving occupants privacy and peace of mind while still allowing emergency access from the hallway when needed, balancing security with convenience for family members or roommates.
Smooth Quiet Operation: Oil impregnated bushings and precision springs eliminate the gritty feel and loud clicks of budget locks, so doors latch softly and release with minimal effort. The ergonomic knob shape fits comfortably in wet or gloved hands, making entry smooth even when carrying groceries or during inclement weather, enhancing daily usability for busy households and commercial spaces alike.
Two Pack Complete Solution: Sold as a pair, you can secure main and back doors or coordinate multiple interior rooms with matching hardware for a cohesive modern look throughout your home. The matte black finish complements popular paint colors, stainless appliances and farmhouse décor trends, increasing property value and curb appeal while providing dependable keyed security that residents and guests will appreciate every day.
