Door Knob & Deadbolt Replacement

Most homeowners don't replace a door knob with lock until something completely fails — the key snaps, the latch stops catching, or the knob spins freely. But the real danger is subtler. A worn cylinder develops what locksmiths call 'sloppy tolerances,' meaning the pins no longer align tightly with the shear line. That makes the lock significantly easier to manipulate without the correct key. If you've noticed your key turning more loosely than it used to, or if the lock feels gritty when you turn it, those are early warnings worth taking seriously — not inconveniences to ignore until spring cleaning.

Deadbolts carry their own failure patterns. A single-cylinder deadbolt that no longer throws the full bolt length, or whose strike plate screws have pulled away from soft door framing, provides little more than a visual deterrent. Older Marietta homes, particularly craftsman bungalows built near the Kennesaw Avenue corridor, often have original hardware that was never intended for modern threat levels. Upgrading to a Grade 1 or Grade 2 rated deadbolt paired with a reinforced strike plate and three-inch screws changes the physics of a forced-entry attempt dramatically.

When a Marietta Fast Locksmith technician arrives, the first step is always an assessment — not a sales pitch. We examine the door thickness, the backset measurement (typically 2-3/8 or 2-3/4 inches), the handing of the door, and the condition of the existing frame and strike box. This matters because installing a new lock on a damaged frame or a door with a warped edge defeats the purpose of the upgrade. If the frame needs reinforcement, we tell you before we start, and we confirm an exact up-front price covering labor and parts before any work begins. Factors that influence the final quote include the lock grade and brand selected, whether a mortise lock conversion is involved, travel distance within the Marietta service area, and the time of day the call comes in.

The physical swap itself — for a standard cylindrical knob-and-deadbolt set — typically involves removing the existing hardware without gouging the door face, cleaning the bore holes, fitting the new lock body, aligning the latch and bolt with the strike plate, and testing under door-closed conditions to confirm smooth operation in both directions. For more complex installations, such as fitting a mortise lock into a door that previously held a cylindrical set, the process involves routing a precise mortise pocket — which is why this work benefits from a skilled technician with the right chisels and jigs rather than a DIY approach.

A mortise lock is the gold standard for residential and light commercial door security. Unlike a cylindrical lock that sits in a round bore hole, a mortise lock body is recessed into a rectangular pocket cut into the door edge, distributing stress across a larger surface area. This makes them significantly harder to defeat by kicking or prying. Many Marietta homeowners upgrading from a basic door knob with lock and key setup to a mortise lock are surprised by how much more solid the door feels — it's not just perception; the mechanical engagement is fundamentally different. We stock and install mortise lock sets from established hardware manufacturers including Schlage and Kwikset, and we can match finish to your existing door hardware.

If you want keyless entry without sacrificing security, a smart lock door knob or keypad lock door knob may be the right fit. Keypad models eliminate the need to carry keys entirely — practical for households where multiple family members come and go at different times. Smart lock options add remote access, activity logs, and integration with home automation systems. We assess your door prep and Wi-Fi or Bluetooth infrastructure before recommending a specific unit, because not every smart lock works reliably on every door configuration. For households that want the redundancy of both a keyed and a code entry option, a double lock door knob setup or a smart deadbolt paired with a keyed knob gives you layered access without complexity.

People often search questions like 'What proof do I need for a locksmith?' and the answer is straightforward: a professional locksmith will ask you to verify occupancy or ownership before beginning work on a residential door. This typically means a photo ID matching the property address, or in the case of a rental, a lease agreement or landlord authorization. This is a legitimate safeguard — any experienced locksmith who skips this step is cutting corners in a way that should make you cautious. Our technicians always perform this verification as a standard part of every service call, no exceptions.

On the topic of call-out fees: 'What is a locksmith call out fee?' is one of the most common questions we hear. It refers to a base charge for dispatching a technician to your location, separate from the labor and parts involved in the actual work. We explain every component of your quote before starting — travel, hardware, labor — so there are no line items that surprise you on completion. Similarly, 'How much is a locksmith per hour?' is a reasonable question, but hourly billing structures vary by company and job type; we quote by the job rather than purely by the clock, which gives you a predictable total.
