The Science of Precision Installation
ANSI Grade Standards
We only install hardware that meets ANSI ratings. Grade 1: 1 million cycles & heavy impact (Commercial). Grade 2: 400,000 cycles (Heavy Residential). Grade 3: 200,000 cycles (Standard Residential).
Mechanical Alignment
90% of lock failures are caused by improper installation. We use precision jigs to ensure the latch and strike plate align perfectly, preventing friction that wears down internal pins and leads to jammed cylinders over time.
Door Reinforcement
A strong lock is useless on a weak door. We evaluate the door’s structure, installing steel wrap-around plates and extra-long 3-inch screws into the frame studs to prevent kick-ins and forced entry.

Technical Deep Dive: Rekeying vs. Installation
While rekeying is cost-effective for changing access, new installation is necessary when upgrading the security rating or replacing aging, mechanically compromised cylinders. Our technicians provide on-site security audits to determine which path provides the highest ROI for your safety.
