SCHLAGE B62N622 Deadbolt Keyed Both Sides Matte Black - Secure

Our review of the SCHLAGE B62N622 Deadbolt finds it best for homeowners and contractors who need a high-security deadbolt that works with a key on both sides of the door. The single biggest reason to buy is its ANSI/BHMA Grade 1 rating, which means the lock is designed to resist common forced-entry methods while the Matte Black finish provides a discreet, modern look. This review examines installation, durability, and daily use so you can decide whether a double-cylinder deadbolt is the right choice for your exterior door.

Key Features

• Double-cylinder operation: Locks and unlocks with a key on the exterior and interior for added security where an interior key is required to prevent easy access through glass panels.
• ANSI/BHMA Grade 1 security: Built to the highest residential/commercial performance standard, offering strong resistance to crowbar, hammer, wrench, saw, lock pick, and kick-in attacks.
• Snap 'n' Stay design: The unique mounting holds the deadbolt in place during installation, making alignment and tightening simpler and faster for DIYers and pros.
• Standard door prep fit: Designed to fit existing pre-drilled holes, which reduces the need for door modifications and speeds up replacement projects.
• Matte Black finish: A low-glare, modern finish that complements common exterior hardware and hides fingerprints and minor wear.
• Measure-first reminder: The product notes emphasize measuring backset, cross bore, and door thickness to ensure correct fit and avoid returns.

Who It's For

The SCHLAGE B62N622 is ideal for homeowners with exterior doors that include glass panels or sidelights where a keyed interior cylinder is preferred to prevent an intruder from breaking glass and reaching the inside thumbturn. It also suits contractors and landlords who need a high-security deadbolt that meets Grade 1 standards for durability and forced-entry resistance.

It is less suitable for households wanting quick single-handed egress or for doors where local fire codes require a thumbturn for emergency exit; those buyers should consider a single-cylinder deadbolt or consult local regulations before choosing a double-cylinder model.

Pros & Cons

Pros

• Top-tier ANSI/BHMA Grade 1 protection provides superior resistance to forced entry.
• Snap 'n' Stay design simplifies installation and keeps the deadbolt steady while securing hardware.
• Matte Black finish offers a contemporary look that hides wear and coordinates with common exterior hardware.
• Fits standard door prep so many replacements avoid drilling new holes.

Cons

• Double-cylinder design requires a key to exit, which can complicate emergency egress and may conflict with some local codes.
• Buyers must carefully measure backset, cross bore, and door thickness to ensure proper fit before purchasing.
