Door Knob & Deadbolt Installation

A door knob lock replacement sounds simple until you are standing in the hardware aisle staring at backset measurements, spindle sizes, and strike plate options. Every residential door has specific dimensions — the bore hole diameter, the backset distance from the door edge to the center of the hole, and the latch faceplate size all have to match the new hardware precisely. Get any one of those wrong and the door either binds, latches loosely, or leaves a visible gap around the plate. Our technicians measure first, source the right hardware for your door, and then install it cleanly without gouging the door face or splitting the jamb around the strike plate.

Deadbolts add a separate layer of protection that a spring-latch door knob with lock simply cannot provide on its own. A single-cylinder deadbolt is the most common residential upgrade — keyed on the outside, thumb-turn on the inside. We also install double-cylinder deadbolts (keyed on both sides) for doors with glass panels where a thumb-turn could be reached through broken glass, though we always walk homeowners through the egress trade-offs before proceeding. For older Stone Mountain bungalows and craftsman-style homes with thicker door stiles, we frequently recommend a mortise lock body, which integrates the latch, deadbolt, and sometimes a night-latch function into a single recessed unit machined directly into the door edge — far more robust than a bored cylindrical lock in heavy-use applications.

A mortise lock is not a product you will find pre-packaged at a big-box store, and for good reason — installation requires routing a precisely sized pocket into the door stile, fitting the lock body flush, and aligning the cylinder, lever or knob trim, and strike box so everything operates without binding. Done correctly, a mortise lock is among the most secure and durable residential lock types available, with a lifespan that can far outlast standard cylindrical hardware. Our technicians carry the tooling to perform mortise lock installations on-site, whether you are upgrading an original 1950s entry door near the Stone Mountain Village district or retrofitting a newer door on a property along Rockbridge Road.

When a mortise lock is the right call, we will tell you — and when a high-grade cylindrical deadbolt and door knob with lock and key set is the better fit for your door construction and budget, we will tell you that too. Our job is to give you accurate information, not to upsell hardware you do not need. Before any work begins, we confirm a firm, up-front price that accounts for the lock type, the complexity of the installation, travel distance, and the time of day — so there are no surprises on the final invoice.

The category of door knob locks has expanded well beyond the traditional keyed knob. Homeowners across the Stone Mountain area are increasingly asking about smart lock door knob conversions — Wi-Fi or Bluetooth-enabled hardware that pairs with a smartphone app, allows remote locking and unlocking, and logs access events. We install and configure these units, set up user codes, and make sure the door prep is correct so the smart lock operates reliably long after we leave. A keypad lock door knob is a popular middle-ground option — no app required, no key to lose, just a PIN that can be changed whenever needed. These are especially practical for households with kids, frequent guests, or short-term rental properties.

We also handle door knob with lock for bedroom applications, interior privacy locks, passage sets, and specialty hardware for older doors that no longer match standard bore dimensions. If you have been searching online for how to pick a door knob lock out of curiosity about your own security — that curiosity is well-placed. Many standard cylindrical knob locks can be defeated quickly by someone with basic tools and knowledge. The honest answer to that question is: rather than exploring bypass methods, the more productive step is to call our team and ask what upgrade would make your door genuinely resistant. We assess your existing hardware and tell you plainly whether it is adequate or whether a deadbolt, a mortise lock, or reinforced strike plate hardware would close the gap. Call (770) 615-2479 any time — we answer around the clock.

Because we are fully mobile, there is no shop drop-off, no scheduling around a fixed service window weeks out, and no need to remove your door hardware and bring it somewhere. We come to your Stone Mountain address — residential properties, apartment units, small rental homes — with the tools and a working inventory of commonly used hardware. For specialty or high-security lock bodies, we will confirm parts availability before committing to a same-visit installation, so you are never left waiting with a half-finished door. Our technicians verify ownership or occupancy before beginning any lock work, which protects you and ensures our service is never used to compromise someone else's property.

Every job is approached with a damage-free mindset: we use the correct drill guides and chisel techniques to avoid splintering frames, and we take care around painted or stained door surfaces that are difficult to touch up. When the work is complete, we test the lock through multiple cycles with both the key and any interior function, check that the door closes and latches without force, and confirm that strike plate screws penetrate deep enough into the door frame stud — not just the thin jamb casing — which is one of the most commonly overlooked security details on residential door installations. If you are ready to schedule or just want a straight answer about what your door needs, call (770) 615-2479 — we are available 24/7 and we will give you honest, straightforward guidance from the first call.
