Grade 1 vs. Grade 2 Deadbolt Installation: Choosing the Right Security Level
Not every exterior door needs the same lock, and one of the most useful things our technicians do before touching a single tool is assess which grade is appropriate for your specific entry point. ANSI Grade 1 deadbolts are the highest residential standard — they withstand more kick-force, more twisting stress, and more repeated use cycles than their Grade 2 counterparts. If you are securing a front door that faces a public street in a high-traffic Cherry Hill Township neighborhood, a primary entry on a rental property, or any door that a vulnerable household member relies on, Grade 1 is the recommendation. Grade 2 deadbolts still exceed most builder-grade hardware and are well suited to secondary exterior doors, side entrances, or garage access doors where foot traffic is lower.
The lock grade is only part of the equation. A Grade 1 deadbolt installed into a weak door frame with a shallow strike plate loses most of its advantage within the first solid kick. Our deadbolt installation process always accounts for the full door assembly — door material, jamb condition, existing bore diameter, and the depth of the strike plate mortise. Where the existing frame is undersized or the strike plate screws are too short, we address those issues as part of the installation rather than leaving a hidden weak point behind. That attention to the full system, not just the hardware itself, is what separates a professional locksmith installation from a self-installed unit that looks right but underperforms under pressure.
