Fast, Reliable Access Control Systems Across Decatur
Access control systems in Decatur, GA typically run $1,800-$4,500 for a multi-tenant keypad or card-reader installation, with restricted-keyway master key systems starting around $650 per cylinder rekeyed and re-pinned. Most Decatur properties near Agnes Scott College and along the South McDonough Street rental corridor can be surveyed and scoped within 48 hours, with installation scheduled to avoid tenant disruption. Call Novak Lock & Security Atlanta at (470) 944-6813 for a written estimate before any work begins - Haven Standard Clause 1: the price on the phone is the price on the invoice.
We know Decatur’s buildings. The 1920s craftsman four-plexes in Oakhurst, the cottage courts near Winnona Park, the mid-century walk-ups off East College Avenue - these properties weren’t built for modern access control, and retrofitting them without damaging original fabric takes trade knowledge you can’t get from a national installer. Our Access Control Systems team works from our Atlanta office and dispatches to Decatur daily. We’ve rekeyed mortise boxes in bungalows built before the Great Depression and installed keypad entry on freeholder doors where a single copied skeleton key had compromised every unit in the building.
Why Novak Lock & Security Atlanta Is Decatur’s Preferred Access Control Systems Company
Decatur landlords and property managers call us because we name the price before we drive and we document what we found when we leave. Since 2002, Novak Lock & Security has installed or serviced over 60,000 locks, keys, and systems - every one with a written price quoted upfront and a photo record provided at completion. The 365-Day Done Right Promise applies to every access control job in Decatur: if the keypad timing is off, if a cylinder doesn’t turn smooth, if a strike plate needs readjustment after summer swelling, we make it right.
Our technicians are background-checked, uniformed, and work to The Haven Standard, the same documentation framework applied across all ten Haven brands. Calls are answered by a live person, 24/7 - no voicemail queue, no callback window. For Decatur properties, that matters when a tenant is locked out at 11 PM on a Saturday and the freeholder lives in another county.
We understand the local conditions that affect access control in Decatur. The humid subtropical summers here routinely push humidity above 80% for weeks, swelling the old-growth pine and fir door frames in pre-WWII bungalows until deadbolt throws bind against strike plates. Tenants call reporting a “broken keypad” or “stuck lock” when the mechanism is fine and the frame needs planing or strike adjustment. A technician who doesn’t know Decatur’s housing stock replaces hardware that isn’t broken. We adjust first.
Our crew responded to a 1930s craftsman four-plex on South McDonough Street where every unit still ran original mortise lock boxes from a single master key system - a former housemate’s copied key had been passed around, and the freeholder wanted key control restored without touching the door’s original wooden frame. We rekeyed each lock cylinder to a bump-resistant Medeco restricted keyway so the old blanks would not fit any key machine in town, and we adjusted the strike plates on two swollen fir doors so the deadbolt throws cleared the plates cleanly. The freeholder kept the historic doors intact and every tenant got a non-duplicable key.
Our Access Control Systems Services in Decatur

Multi-Tenant Access Control and Master Key Systems
Decatur’s rental corridors - especially the dense blocks off South McDonough Street and East College Avenue near Agnes Scott College - run on converted single-family homes and small apartment buildings where one freeholder key once opened every door. We design master key systems that restore granular control: a master key for the freeholder, sub-master keys for building managers, and individual keys that open only one unit. For a typical Decatur four-plex with original mortise hardware, a full master key rekey runs $1,200-$2,800 depending on cylinder count and keyway grade. We quote the full scope in writing before scheduling.

Key Control Programs with Restricted, Non-Duplicable Keyways
Because nearly all of Decatur’s historic core was built before 1950, a single copied key in a multi-tenant building means every original mortise lock cylinder on that property shares the same blank profile that big-box key machines can duplicate. That building-wide exposure is unique to Decatur’s dense pre-WWII housing stock, unlike the newer DeKalb subdivisions where restricted-keyway hardware is standard from day one. We upgrade existing cylinders to Medeco, Mul-T-Lock, or Abloy restricted keyways - locks that cannot be picked or bumped by standard tools, and whose blanks are not available to hardware store key machines. A restricted-keyway rekey on a Decatur mortise cylinder typically runs $180-$340 per lock, including two keys. Additional keys are cut only with written authorization and a signature match.

Non-Destructive Entry and Lock Cylinder Work on Original Mortise Hardware
Residents locked out of a unit in a multi-tenant building often call for an emergency drill, but a keypad entry or lock cylinder on the freeholder’s original door should be opened non-destructively - drilling a heritage door costs the freeholder far more than the entry itself. Our technicians carry mortise lock picks, skeleton key sets, and bypass tools specific to pre-WWII hardware. We open the lock, document the condition with photos, and leave the door intact. Emergency non-destructive entry in Decatur runs $150-$280 during standard hours, $220-$380 after hours. The price is quoted on the phone and is the price on the invoice.

Keypad and Card Reader Installation for Decatur Rental Properties
For freeholders who want to eliminate keys entirely, we install standalone and networked keypad entry systems that integrate with existing mortise lock boxes where possible - preserving the original door while adding programmable access. A single-door keypad retrofit on a Decatur heritage property typically runs $1,800-$2,800 including hardware, wiring, and programming. Multi-door networked systems for larger Decatur apartment buildings range from $4,500-$8,500 depending on door count, network infrastructure, and integration requirements. Every installation includes a written scope, a programming tutorial for the property manager, and a 365-Day Done Right Promise.

Trusted Brands We Service in Decatur
We stock and service Kwikset, Medeco, and Baldwin hardware from our Atlanta office, with same-day or next-day parts availability for Decatur properties. Medeco’s restricted keyways are our standard recommendation for Decatur multi-tenant buildings where key control is the priority - the blanks are factory-controlled and not available through retail channels. Baldwin mortise lock sets match the aesthetic of Decatur’s craftsman bungalows when a freeholder wants security without visual compromise. Kwikset SmartKey cylinders offer a budget-friendly rekey option for rental turnovers in Decatur’s 1950s-60s ranch properties where the hardware is newer and the threat model is different. We don’t sell brands we can’t support locally; every system we install, we can also service.
Common Access Control Systems Problems We See in Decatur Homes

- A single duplicated skeleton key compromises every unit in the building. Decatur’s pre-WWII lock boxes share common blank profiles that any hardware store can copy, so one leaked key opens every door on the property. We diagnose this exposure during our initial survey and quote a restricted-keyway upgrade that breaks the chain.
- Summer humidity swells original pine and fir door frames until deadbolts bind. Tenants in Decatur bungalows report a “broken keypad” or “stuck lock” every August when the real problem is frame expansion. We plane the door edge or relocate the strike plate rather than replace functional hardware.
- Master key systems in old Decatur four-plexes have no audit trail. A former tenant’s key still works because the freeholder never rekeyed between leases. We implement a rekey protocol with documented key issuance so every turnover resets access cleanly.
- Emergency drilling destroys heritage doors that cost more to replace than the entry service. Technicians unfamiliar with mortise locks drill first and ask questions later. We carry the picks and bypass tools to open Decatur’s antique hardware without damage, and we document the method with photos.

FAQs - Access Control Systems in Decatur

Yes. We install keypad-controlled electric strikes or magnetic locks that work with your existing mortise hardware, preserving the original door and frame. For a typical Decatur four-plex with heritage doors, we mount the keypad and wire an electric strike behind the existing mortise box - the tenant punches a code, the strike releases, and the original lock remains intact for key override. The installation runs $1,800-$2,800 per door depending on wiring distance and network requirements. Call (470) 944-6813 for a written scope and exact quote - estimates are free.
Probably not. Decatur’s humid subtropical summers push humidity above 80% for weeks, swelling old-growth pine and fir door frames until the deadbolt throw binds against the strike plate. We see this every August in Oakhurst and Winnona Park. The lock mechanism is fine; the frame needs planing or the strike plate needs relocation. A seasonal adjustment runs $120-$220, quoted in writing before we start. If the hardware is actually worn, we’ll show you the wear pattern in the photo record and quote replacement separately - no combined invoice, no surprise.
It restores control where one original key once opened every door. Decatur’s pre-1950 multi-tenant buildings were often converted from single-family homes with matching mortise cylinders throughout - one copied key compromises the entire property. We rekey each cylinder to a master key hierarchy: individual keys open one unit, sub-masters open designated groups, and the freeholder holds the top-level master. For a typical Decatur four-plex, the full design and rekey runs $1,200-$2,800. Every key is tracked; every rekey between leases is documented. Call (470) 944-6813 to schedule a survey.
Experienced Decatur locksmiths block that week out months in advance. The late-August student move-in triggers a concentrated surge of rekeying calls from landlords in the rental corridors just off South McDonough Street and East College Avenue - new leases, roommate changes, turnover cleaning crews who had temporary access. We schedule these jobs in batches to minimize per-unit cost: $65-$95 per cylinder when three or more units in the same building are rekeyed the same day. Book by early August to secure your slot; walk-ins during move-in week face standard rates and longer waits.
Non-destructive entry means opening a locked door without drilling, cutting, or damaging the lock, frame, or door itself. It matters in Decatur because a replacement mortise lock set for a 1920s craftsman door can cost $800-$1,500 if the original hardware is no longer manufactured, and a drilled heritage door may require full replacement. Our technicians carry picks and bypass tools specific to pre-WWII mortise locks, skeleton keyways, and antique rim locks. We open the door, photograph the undamaged condition, and leave the original fabric intact. Emergency non-destructive entry in Decatur runs $150-$280 standard hours, $220-$380 after hours - the price on the phone is the price on the invoice.
