Door Knob Lock Installation: Choosing the Right Hardware for Your Home
Not every door knob with lock and key performs the same way, and the difference matters more than most homeowners realize. A Grade 3 residential knob set — the kind often used on interior bedroom or bathroom doors — offers privacy, not real security. Entry-grade knob sets rated Grade 1 or Grade 2 under ANSI/BHMA standards withstand significantly more force, which matters on a front or side door. Our technicians assess your existing door prep (the bore diameter, backset measurement, and cross-bore location) before recommending hardware, so the new lock seats correctly without shimming, filler plates, or compromised alignment. We commonly install Schlage, Kwikset, and Baldwin entry sets, and we always pair a new knob set with a properly fitted strike plate — since a deadbolt or knob lock is only as strong as the frame it's anchored to.
We also handle full door lock installation projects where the previous hardware has failed, been damaged, or was simply the wrong grade for the application. Rekeying an existing knob lock to match a new key is an option when the hardware itself is still sound — we can cut new keys on-site and rekey the cylinder to your existing key profile or to a new one entirely. For homes with multiple exterior doors, a master-key or key-alike setup means one key operates every lock on the property, which is a practical upgrade many Washingtonville homeowners request when they're already having work done.
