The deadbolt is the single most important piece of hardware standing between your home and a forced entry. A quality, correctly installed deadbolt resists kicks, pries, and picks far better than a knob lock ever could — and a worn or low-grade deadbolt gives a false sense of security.
OE Lock & Safe replaces deadbolts throughout the San Fernando Valley with high-security, properly graded hardware, anchored into the frame the right way. If your deadbolt is loose, sticky, outdated, or you simply want a stronger lock, here's what to know.
Why deadbolt quality matters
Not all deadbolts are equal. Locks are rated by ANSI/BHMA grade: Grade 1 is the strongest (commercial-level), Grade 2 is a solid residential choice, and Grade 3 is basic builder hardware. Upgrading from a builder-basic deadbolt to a Grade 1 or Grade 2 lock is one of the most cost-effective security improvements you can make.
- Grade 1 — highest residential/commercial security, best resistance to force
- Grade 2 — strong residential protection at a reasonable price
- Anti-bump and anti-pick cylinders defeat common attack methods
- A reinforced strike plate anchors the bolt deep into the frame
Single-cylinder vs. double-cylinder deadbolts
A single-cylinder deadbolt uses a key outside and a thumb-turn inside — the most common and convenient choice. A double-cylinder deadbolt requires a key on both sides, which prevents someone from reaching through a broken window to unlock the door, but can slow your exit in an emergency. We'll help you choose the right type for your door and local safety considerations.
Signs your deadbolt needs replacing
- The bolt doesn't extend fully or feels loose in the door
- The key sticks, grinds, or the lock feels gritty to turn
- The deadbolt is a thin, low-grade builder model
- There's damage from an attempted break-in
- You've lost keys and want fresh, secure hardware
Proper installation is half the security
Even the best deadbolt is only as strong as its installation. We make sure the bolt seats deep in a properly aligned strike, anchor the strike plate to the frame with long screws, and confirm the door closes and locks smoothly. Sloppy installation is a common reason good locks still fail — we don't cut corners.
