We’ve been serving Marietta homeowners for over 42 years, from the Victorian porches near Marietta Square to the custom carriage-house doors of East Cobb. Our Residential Locksmith team knows the difference between a 1920s mortise box and a modern smart-lock retrofit, and we stock the hardware to handle both. Marietta’s housing stock spans roughly 150 years in close proximity, and that range means a single technician’s day can move from fabricating a skeleton key for a historic bit-key lock to programming a Z-Wave deadbolt in a Walton’s Ford subdivision. We don’t subcontract. Our technicians are background-checked, uniformed, and present company ID at your door on every visit.
Why Strongbox Lock & Safe Co. Is Marietta’s Preferred Residential Locksmith Company
Marietta presents an unusually bifurcated locksmith market: the Marietta Square historic district anchors a core of genuine 19th-century commercial and residential buildings still using original mortise and skeleton-key hardware, while the East Cobb corridor (ZIP 30062) is one of metro Atlanta’s wealthiest suburban zones with constant demand for high-security Grade 1 deadbolts and smart-lock retrofits. No neighboring city - not Smyrna, not Kennesaw - has this same pairing of antique lock restoration work and luxury access-control upgrades within the same service area. We’ve built our reputation in Marietta by mastering both ends of that spectrum.
Our reviews from Marietta customers consistently mention two things: we show up when we say we will, and the price on the invoice matches the price quoted on the phone. No bait, no switch, no “service fee” surprises. A square deal: the price we quote is the price you pay.
Response time to Marietta neighborhoods averages 30-45 minutes for emergency lockouts. We know the local roads - Roswell Street through the Square, Johnson Ferry into East Cobb, the winding streets off Whitlock Avenue - so we don’t waste time with GPS confusion. And we understand Marietta’s specific conditions. The hot, humid Georgia summers cause wood door frames, especially prevalent in the older ranch and bungalow stock, to swell significantly. That shifts strike plate alignment and makes deadbolts drag or fail to throw fully. This generates a predictable spike in service calls from June through August that is more acute here than in drier inland markets. We plan for it, and we fix it right.
Our Residential Locksmith Services in Marietta
Lock Change
A full lock change in Marietta runs $140-$280 for standard deadbolts and knob sets, with high-security upgrades ranging higher. We recommend lock changes after a move, a lost key, or any situation where you cannot account for every copy. In Marietta’s older ranch homes throughout the 30060 and 30008 ZIP codes, we often find aging Kwikset and Schlage B-series hardware that has outlasted its reliable service life. We remove the old hardware, inspect the door bore and face for wear, and install new Grade 2 or Grade 1 hardware that fits properly. Done right - and backed in writing with our 90-Day Done Right Promise.

Residential Lockout
Locked out in Marietta? Our emergency lockout service is $89-$150 depending on time and complexity. We answer live, 24/7, and our average response to Marietta Square, East Cobb, and the Whitlock Avenue corridor is 30-45 minutes. We use non-destructive entry techniques on wood doors, fiberglass, and steel - no drilling unless the lock has already failed mechanically. Last summer, we rekeyed a 1903 Victorian on Church Street near the Square. The homeowner’s original mortise lock had a non-standard Sargent keyway; we had to custom-cut a new skeleton key from a blank, then match the existing bit pattern to ensure smooth operation with the original brass escutcheon. That kind of precision matters when you’re dealing with irreplaceable historic hardware.

Deadbolt Installation
Deadbolt installation in Marietta ranges from $120 for a standard single-cylinder replacement to $340 for high-security Grade 1 deadbolts with reinforced strike plates. This is one of our most requested services in East Cobb, where custom carriage-house doors and heavy wood entry doors demand more than a box-store special. Standard-length screws often don’t penetrate deep enough into the frame on these thicker doors. We use longer, hardened screws and proper strike-box reinforcement to ensure the deadbolt throws fully and holds against forced entry. We install and service Schlage, Medeco, Mul-T-Lock, and other premium brands - the right lock for the right door, not just what happens to be on the truck.

Lock Rekey
Rekeying in Marietta costs $89-$150 for most residential locks, with additional charges for non-standard keyways or antique hardware. Rekeying changes the internal pin configuration so old keys no longer work - a smart move after moving into a new home, after a roommate departs, or when you want to unify multiple locks to a single key. In Marietta’s historic Square district, we regularly rekey original mortise locksets without replacing them. This preserves the home’s character and avoids the damage that comes from forcing modern hardware into non-standard preparations. We also rekey standard Kwikset and Schlage deadbolts and knobs throughout west and central Marietta, matching everything to one key when possible.

Window Lock & Door Reinforcement
Window lock installation and door reinforcement in Marietta typically runs $75-$200 per opening. Door reinforcement includes strike-plate upgrades, jamb shielding, and hinge reinforcement - particularly valuable for the post-WWII ranch homes in 30008 and 30060 where original frames have softened with age and Georgia humidity. We assess each door’s condition, check for frame swelling or settling, and install reinforcement that works with the door you have, not against it.

Trusted Brands We Service in Marietta
We install and service Schlage, Kwikset, Medeco, and Yale hardware from our local inventory, which means most Marietta jobs are completed in a single visit without waiting for parts. For the East Cobb homes with existing Medeco or Mul-T-Lock high-security systems, we stock cylinders and key blanks that many competitors must special-order. For the historic mortise locks near Marietta Square, we maintain relationships with specialty suppliers for obsolete cylinders and bit-key blanks. The right part matters. A Kwikset keyway forced into an antique Sargent mortise box destroys both. We know the difference, and we stock accordingly.
Common Residential Locksmith Problems We See in Marietta Homes
- Historic mortise lock mismatches. Homeowners near Marietta Square assume modern Kwikset or Schlage keyways will fit their antique mortise locks. They don’t. Forcing them damages the original hardware beyond repair. We fabricate proper skeleton keys or source correct cylinders instead.
- Deadbolt drag on carriage-house doors. East Cobb’s custom wood doors are thicker than standard. Standard-length screws don’t reach the frame, and deadbolts don’t throw fully. We use extended hardware and proper strike-box depth for a clean, secure fit.
- Seasonal swelling misalignment. Marietta’s humid summers swell older door frames, especially in the ranch and bungalow stock. A deadbolt that worked in March can stick by July without strike-plate adjustment. We account for this in every installation and adjustment.
- Worn builder-grade hardware in aging subdivisions. The 1980s-2000s homes in East Cobb and Walton’s Ford are now old enough for original locks to be worn, sticky, or failing. We upgrade to Grade 2 or Grade 1 hardware with proper preparation, not quick replacements that repeat the same problems.

The fix is usually a combination of strike-plate realignment and hardware adjustment for seasonal frame swelling, plus longer screws or a deeper strike box if the door is thicker than standard. Marietta’s humid summers swell wood frames more than drier climates, and East Cobb’s custom carriage-house doors are often 2¼ inches thick or more.

Yes. We install Z-Wave and Wi-Fi smart locks on heavy custom wood doors in Walton’s Ford and similar East Cobb subdivisions, including proper bore preparation, reinforcement, and integration with existing deadbolt spacing.
