Door Knob Lock Installation

Installing a door knob with lock sounds straightforward until you're dealing with a misaligned bore hole, a door that has swelled from Denver's humidity swings, or an exterior frame that needs a reinforced strike plate to meet modern security standards. Our technicians begin every job with a door assessment — checking the backset measurement (typically 2-3/8 inch or 2-3/4 inch), the cross bore diameter, the door thickness, and whether the existing prep work is compatible with the replacement hardware. Skipping that step is why so-called quick installations often result in a lock door knob that binds, doesn't latch cleanly, or leaves visible gaps around the faceplate.

For exterior applications, we strongly recommend Grade 1 or Grade 2 ANSI-rated knob and lever sets — hardware brands like Schlage and Kwikset both offer solid options in these grades. We also replace standard builder-grade strike plates with heavy-gauge, three-inch screw versions that anchor into the door stud rather than just the jamb casing, a detail that makes a significant difference in kick-resistance. If your project involves an older Denver home with a thick mortise-cut door, we can discuss whether a traditional mortise lock installation is the more appropriate upgrade, since mortise lock hardware offers a larger bolt throw and more robust chassis than a cylindrical knob lock alone.

Lockouts happen at the least convenient times — late on a Saturday night near Colfax Avenue, early on a frozen January morning in Stapleton, or mid-afternoon during a business day in LoDo. When you're locked out, the instinct to search for ways to pick or bypass a lock is understandable, but attempting to manipulate a lock door knob without the right tools almost always results in damage to the cylinder, the finish, or the door itself. The safe and practical steps are: check for a spare key with a trusted neighbor, verify whether another entry point in the property is accessible, and then call a professional. Our emergency locksmith team is mobile and dispatched across Denver and surrounding communities 24/7 — we verify ownership or occupancy before any work is performed, and we aim to open your door without damage wherever the lock mechanism allows.

The same 24/7 availability applies to upgrade and installation calls, not just emergencies. If you've just moved into a new place in Wash Park or taken over a commercial lease in Ballpark and want every knob lock rekeyed or replaced before the first night, we can schedule same-day or after-hours visits. During those appointments, we can also evaluate whether a smart lock installation makes sense for your property — keypad deadbolts and app-connected lever sets are increasingly popular in Denver's short-term rental and co-working markets, and we install and configure them so they work correctly from day one rather than leaving setup to trial and error. Call (704) 850-6756 — we answer every call 24 hours a day.

Two questions come up constantly: can you rekey a lock without having the original key, and can a locksmith make a key for a car when all copies have been lost? The answer to both is yes — with qualifications. Rekeying a door knob lock without the original key requires the technician to first pick or decode the existing cylinder to determine the current pin configuration, then repin it to a new key. It is a legitimate service we perform regularly for new homeowners or tenants who cannot obtain the previous occupant's key, and it is far less expensive than a full lock replacement when the hardware is otherwise in good condition.

For automotive situations — a car key lost entirely, no spare, no valet key — our technicians can produce a working key for most makes and models through key cutting and, where required, transponder programming or key fob pairing. The process depends on the vehicle year, make, and whether the car uses a standard metal key, a transponder chip key, or a proximity smart key. We verify ownership documentation before beginning any automotive key work, the same standard we hold for all lock and key services. If you also need a duplicate made while we're on-site for your door knob with lock and key, we can handle both in the same visit.
