Fast, Reliable Access Control Systems Across Marietta
Access control installation and repair in Marietta typically runs $1,800-$4,500 for a standard residential keypad and smart lock system, with most jobs surveyed and scheduled within 48 hours. We dispatch from our Atlanta office and serve Marietta properties directly - no subcontracting, no callback windows.
We’ve worked the full arc of Marietta housing: cast-iron mortise locks in antebellum homes near Marietta Square, fatigued contractor-grade deadbolts in 1980s East Cobb subdivisions, and everything between. That range matters because access control on a pre-1900 door with original hardware is a different job than retrofitting a smart keypad onto a standard modern entry. Our Access Control Systems team handles both, and we quote every scope in writing before any work starts. Call (470) 944-6813 for a free estimate.

Mortise Lock Servicing and Skeleton-Key-to-Modern-Cylinder Conversion
The antebellum and late-Victorian homes on Kennesaw Avenue and Cherokee Street near Marietta Square still run original cast-iron mortise locks. A technician who can’t source parts for a Corbin or Sargent mortise set, or re-key a warded lock, loses those jobs to Atlanta specialists. We keep those parts in stock.
We were called to a late-Victorian home on Kennesaw Avenue near Marietta Square where the original cast-iron mortise lock had been painted over and the skeleton key no longer turned. Our tech did non-destructive entry, sourced a replacement cylinder for the Corbin mortise set, and re-keyed it to a modern pin and tumbler keyway so the homeowner could keep the historic hardware. That same week, we swapped a worn Kwikset deadbolt on a 1989 brick-front Colonial off Barrett Parkway for an ANSI Grade 1 Schlage and re-keyed the remaining exterior locks to match.
Conversion pricing for mortise cylinder upgrades in Marietta typically runs $280-$520 per door, including parts and re-keying to match your existing keyway.
Rekey vs. Replace Evaluation for Fatigued Deadbolts
The 1980s-1990s brick-front Colonials and traditional homes across East Cobb and Barrett Parkway corridors were fitted originally with contractor-grade Kwikset or Schlage deadbolts. After 30-40 years of use, plus Georgia’s seasonal humidity cycles, those cylinders wear. Keys jam. Tumblers stick. Homeowners assume they need full replacement when a rekey would restore function at a fraction of the cost.
We evaluate the actual condition: pin wear, cylinder scoring, strike alignment, and door frame settlement. If the lock body is sound and the bolt throws cleanly, a rekey ($45-$85 per cylinder in Marietta) usually solves it. If the internal mechanism is cracked or the bolt face is worn past spec, we quote replacement with an ANSI Grade 1 or 2 unit, installed and re-keyed to match.
Smart Lock and Keypad Entry Upgrades for Historic and Builder-Grade Doors
Access control on a Marietta home means different hardware depending on the door itself. A standard smart deadbolt - Schlage Encode, Yale Assure Lock SL, or similar - installs cleanly on most post-1980 doors with standard 2-1/8″ bore holes. Pre-1900 doors with mortise pockets require adapter plates or full mortise-to-bored-lock conversion, which we quote separately.
For historic homes near Marietta Square, we often recommend a hybrid approach: keep the original mortise lock as the primary security element and add a standalone keypad-controlled deadbolt above it on a reinforced strike. This preserves the hardware’s character while adding modern access control. For East Cobb homes with standard bored locks, we can drop in a WiFi-connected smart lock with app control and temporary code generation in about 45 minutes.
Smart lock installation in Marietta ranges from $180-$340 for a standard bored-lock retrofit to $420-$680 for mortise-compatible or dual-lock configurations requiring custom strike reinforcement.
Commercial Access Control for Marietta Businesses
Marietta’s commercial base - law offices near the Square, medical practices along Roswell Road, retail along Barrett Parkway - needs keyed entry, keypad access, and audit-trail logging. We install and maintain standalone keypad locks, hardwired access control panels with card readers, and cloud-managed systems with remote code administration. Every commercial scope starts with a written survey and flat per-lock pricing. No dispatch-time language here: these jobs are scheduled, scoped, and priced before any hardware is ordered.

Trusted Brands We Service in Marietta
We stock and install Schlage, Kwikset, Medeco, and Yale across our Atlanta-area inventory, with same-day or next-day part availability for most Marietta service calls. Schlage Encode and Yale Assure series are our most-requested smart lock lines for East Cobb retrofits. Medeco high-security cylinders go into commercial access control systems and residential upgrades where key control is critical - no unauthorized duplication possible without the original card and signature. We don’t push brands. We match the hardware to the door, the use case, and the budget, then put it in writing.
Common Access Control Systems Problems We See in Marietta Homes
- Humidity-swollen doors binding mortise bolts near Marietta Square. Georgia summer humidity causes significant wood movement in original door frames. The mortise lock bolt binds against a misaligned strike plate. Homeowners call thinking the lock has failed; often the frame simply needs adjustment and the strike repositioned. We diagnose this on site and quote both options.
- Worn pin-tumbler cylinders in 1980s-1990s East Cobb deadbolts. Thirty to forty years of key cycles wear the pin chambers. Keys stick, require jiggling, or stop working entirely. A rekey with fresh pins and springs usually restores smooth operation. We check cylinder wall scoring before recommending it.
- Freeze-thaw damage to unlubricated mortise locks after ice events. The January 2014 storm exposed how vulnerable original hardware is. Water enters worn keyways, freezes, expands, and cracks cast-iron bodies. Pre-storm lubrication and weatherstripping maintenance prevent most of this; post-storm, we assess whether the body is salvageable.
- Smart lock battery failure during temperature swings. Georgia’s 90°F summer highs and occasional winter lows below 20°F drain lithium batteries faster than moderate climates. We see this on east-facing doors in East Cobb that catch morning sun then evening shade. We spec alkaline backup options and hardwired alternatives where the door supports it.

FAQs - Access Control Systems in Marietta
Yes. We convert most Corbin, Sargent, and similar mortise sets to modern pin-tumbler cylinders while preserving the original cast-iron body and thumb latch. The skeleton key function is replaced by a standard keyway, but the hardware stays in the door. Conversion runs $280-$520 per door in Marietta. Call (470) 944-6813 for a free estimate - we’ll inspect the body condition and quote exactly.
Probably a rekey, if the lock body is intact. We see this constantly in East Cobb’s 1980s-1990s subdivisions: 30-40 years of pin wear, plus humidity-related frame settlement, makes keys stick. A rekey with fresh pins and springs ($45-$85) usually restores smooth operation. If the cylinder walls are scored or the bolt mechanism is cracked, we’ll quote replacement. We check both on site and tell you which applies before any work starts.
Georgia’s humid subtropical climate swells wood door frames seasonally. The door expands against the jamb, misaligning the bolt with the strike plate. The lock isn’t failing; the geometry is shifting. We adjust the strike, plane the jamb edge if needed, and check that the bolt throws freely. This is routine maintenance for Marietta’s older homes, especially pre-1900 properties near the Square with original wood doors that have seen 120+ summers.
Yes, with adaptation. Standard smart deadbolts require a 2-1/8″ bore hole, which most mortise doors don’t have. We install adapter plates or convert the mortise pocket to accept a modern deadbolt while preserving the original hardware as a secondary element. Some homeowners prefer a standalone keypad lock added above the mortise on a reinforced strike. We survey the door, explain the options, and quote each approach in writing.
Rekeying changes the internal pin combination so old keys no longer work; the lock body stays in place. Replacing removes the entire lock and installs new hardware. Rekeying makes sense when the mechanism is sound but you need key control - new homeowner, lost key, former tenant. Replacing makes sense when the body is damaged, the security grade is insufficient, or you want smart features. In Marietta, we rekey most 1980s-1990s East Cobb deadbolts and replace them only when the internal wear is past spec. For historic mortise locks near the Square, rekeying or cylinder conversion preserves irreplaceable hardware. We evaluate on site and recommend honestly - our 365-Day Done Right Promise covers either path.
