What Our Lock Installation & Rekey Service Includes
Smart Lock Installation
A smart lock replaces your deadbolt or lever with a motorized mechanism controlled by phone, keypad, or voice assistant. Marietta homeowners install these when they want keyless entry for family members, temporary access codes for cleaners or dog walkers, or remote locking after a contractor leaves. We install Wi-Fi and Z-Wave models from Schlage, Yale, and Kwikset, test your home’s signal strength at the door frame, and walk you through the app before we leave. Every smart lock installation includes a written scope stating which features are enabled, which are not, and how to reset the lock if your network changes.
Keyless Entry
Keyless entry systems for residential doors include push-button mechanical locks, electronic deadbolts with touchscreens, and proximity card readers for home offices or detached garages. We install these in Marietta when homeowners are tired of hiding keys under planters, when teenagers lose house keys regularly, or when a rental property needs tenant-specific codes. Our technicians measure backset, door thickness, and bore diameter before quoting, so the hardware we bring fits without modification. We program your codes, demonstrate the override procedure, and document the serial number and programming steps in your written record.
Keypad Lock
A keypad lock is an electronic or mechanical lock opened by entering a numbered code rather than inserting a physical key. These are popular in Marietta for side doors, basement entrances, and home gym or workshop spaces where carrying a key is impractical. We install weather-rated keypad locks rated for Georgia’s humidity and temperature swings, and we recommend models with backlighting for the unlit entries common on homes near Kennesaw Mountain. After installation, we test each button through 500 presses, demonstrate the low-battery warning, and show you where the physical key override is located.
Biometric Lock
Biometric locks use fingerprint recognition to grant access, storing authorized prints locally on the device rather than in the cloud. Marietta homeowners request these for wine rooms, gun safes, home offices with sensitive files, or as the primary entry for households where children or elderly relatives struggle with keys. We install fingerprint locks from manufacturers including Yale and specialty security brands, calibrate the sensor for your specific print, and register backup fingerprints for spouses or emergency contacts. We also demonstrate the physical key or PIN fallback, because biometric sensors can fail when fingers are wet, cut, or worn.
Electronic Lock
Electronic locks encompass any lock powered by electricity or batteries, including motorized deadbolts, electromagnetic strikes, and electric strikes paired with access control. In Marietta, we install these on residential gates, pool enclosures, and home-based business entrances where audit trails or scheduled locking matter. Our technicians test voltage at the installation point, verify your transformer or battery backup capacity, and wire or wirelessly connect the lock to your existing system. Every electronic lock installation includes a written diagram of the wiring path and a test protocol signed by the technician.
Key Duplication
Key duplication creates working copies from an existing key using a code-cutting machine calibrated to the original’s bitting. We duplicate standard Kwikset and Schlage keys, high-security Medeco and Mul-T-Lok keys with restricted keyways, and automotive transponder keys requiring cloning. Our Marietta shop carries key blanks matched to the most common residential hardware in Cobb County, including the Kwikset SmartKey and Schlage SecureKey systems found in homes built after 2015. Each duplicated key is tested in your lock before you leave, and high-security duplicates require ID verification and signature per manufacturer policy.

Brands We Service for Lock Installation & Rekey
We are factory-authorized for premium lock brands and stock OEM parts for same-day completion on most Marietta visits. We’ve serviced hundreds of Medeco high-security cylinders - locks that cannot be picked or bumped by standard tools - and carry their restricted key blanks and pinning kits. Our technicians are trained on Mul-T-Lock interactive and MT5+ systems, including the telescopic pin technology that defines their pick resistance. For Baldwin estate hardware, we maintain the specialized tools required for their mortise lock installations without scratching or marring the finish. We also stock Kwikset SmartKey rekeying tools and Schlage Everest and Primus cylinders for the entry-grade and mid-security hardware common in Marietta’s newer subdivisions.
Whether you have Medeco, Kwikset, Baldwin, or any other make, we can help. Our technicians diagnose the lock on-site, identify the exact model and generation, and quote replacement or rekeying from our mobile inventory. If your hardware is discontinued or specialty-ordered, we tell you before we start, with a written timeline and price for the follow-up visit.
Signs You Need Lock Installation & Rekey Right Now
- Your key sticks, grinds, or requires jiggling to turn. This usually indicates worn pins inside the cylinder or a key that has been duplicated too many times from a worn original. In Marietta’s older homes near Whitlock Avenue, we regularly find original Kwikset hardware from the 1980s with brass pins eroded to half their original diameter. The lock still functions until it doesn’t, and failure typically occurs when you’re carrying groceries in the rain.
- You’ve lost track of who has keys to your home. Previous owners, their adult children, contractors, housekeepers, dog walkers, and real estate agents may all hold copies. Rekeying changes the internal pin configuration so old keys no longer operate the lock, at a fraction of replacement cost. We recommend rekeying on every home purchase in Marietta, and again after any service provider relationship ends on poor terms.
- The lock hardware is loose, misaligned, or pulling away from the door. A deadbolt that no longer throws fully into the strike plate is a lock in name only. We find this often on doors facing west in Marietta, where afternoon sun causes frame expansion and contraction that loosens screws over years. Installation of a properly aligned strike and reinforced strike plate fixes the security gap and prevents the latch failure that leaves you locked out.
- You’ve experienced a break-in, attempted break-in, or domestic dispute. Even if the lock was not damaged, the psychological security of knowing who controls access matters. We install upgraded hardware, rekey existing cylinders, and document the new configuration for insurance or legal purposes. Our photo record provides timestamped evidence of the hardware condition and replacement.
- Your locks are more than 15 years old and you’ve never serviced them. Lock cylinders accumulate dust, pollen, and humidity residue that accelerates wear. In Georgia’s climate, we see spring corrosion and pin sticking in hardware that appears fine from the outside. A rekey includes full disassembly, cleaning, lubrication with graphite or manufacturer-specified compound, and new pins - essentially rebuilding the lock to new condition.
Our Lock Installation & Rekey Process - Step by Step
- 1
Call and receive your written price. When you call (762) 252-5919, a live person answers. You describe your lock, your door, and what you need. We quote a firm price based on hardware grade, door condition, and whether existing holes need modification. Haven Standard Clause 1: the price on the phone is the price on the invoice. The technician is contractually prohibited from changing it at your door.
- 2
Technician arrival and verification. Your technician arrives in a marked Novak Lock & Security van, in uniform, with a photo ID. We verify your identity against the name on the work order, inspect the lock and door frame, and confirm the quoted scope matches the actual conditions. If we find something unexpected - a non-standard backset, a damaged frame, a different brand than described - we explain it, quote the adjustment in writing, and require your signature before proceeding.
- 3
Disassembly and diagnostic. For rekeys, we remove the cylinder, inspect pins, springs, and cam for wear or corrosion, and photograph the internal condition. For installations, we measure bore diameter, door thickness, edge bore alignment, and strike plate depth. We test your door’s swing, frame squareness, and latch engagement with a strike gauge. This diagnostic prevents the callbacks we see from installers who skip measurement and force hardware to fit.
- 4
Execution and testing. Rekeys receive new bottom pins, top pins, and springs matched to your new key’s bitting. Installations receive hardware mounted with proper reinforcement, aligned strikes, and tested operation through 50 cycles. Smart locks and electronic hardware are paired to your network, codes are programmed, and override procedures are demonstrated. Every key is tested in every lock before we proceed to documentation.
- 5
Documentation and warranty activation. You receive a written invoice with the final price matching your quote, a photo record of the completed work, and a warranty card for the 365-Day Done Right Promise. For smart locks and electronic hardware, we leave a printed quick-reference guide with factory support numbers. Your documented record is archived under your address for future service or warranty claims.
How Much Does Lock Installation & Rekey Cost in Marietta?
A standard residential rekey in Marietta runs $95-$145 per cylinder, including disassembly, cleaning, new pins, and two working keys. See our Lock Installation & Rekey cost guide for full pricing: lock installation ranges from $125 for an entry-grade deadbolt in a pre-drilled door to $275 for a high-security cylinder with reinforced strike plate and fresh door preparation. Smart lock installation typically falls between $175 and $325 depending on whether we integrate with existing home automation or run new low-voltage wire.
| Service | Typical Range in Marietta | What’s Included |
|---|---|---|
| Standard rekey (per cylinder) | $95-$145 | Disassembly, cleaning, new pins, 2 keys |
| High-security rekey (Medeco, Mul-T-Lock) | $145-$225 | Restricted pinning, ID-verified key registration |
| Entry-grade deadbolt installation | $125-$175 | Kwikset or Schlage, standard door prep |
| Mid-grade lever or deadbolt installation | $175-$250 | Schlage Grade 2 or Baldwin, reinforced strike |
| Smart lock installation | $175-$325 | Device, app setup, network test, user training |
| Biometric lock installation | $225-$375 | Sensor calibration, backup access setup |
| Key duplication (standard) | $4-$8 per key | Code-cut copy, in-lock verification |
| Key duplication (high-security) | $15-$35 per key | Restricted blank, ID verification, signature |
Several factors affect where your job falls in these ranges. Door material matters: solid-core wood and steel doors accept standard hardware, but fiberglass doors often require specialized backset adapters and careful drilling to prevent splintering. Frame condition matters: a strike plate screwed into rotted or split jambs needs reinforcement, which we quote separately before installing. Hardware grade matters: a Kwikset Grade 3 residential deadbolt installs faster than a Medeco m3 cylinder with sidebar technology that requires precise machining.
To avoid overpaying, get your price in writing before anyone dispatches. Bait-and-switch operations in the locksmith trade quote low on the phone, then claim “unexpected complications” at your door and demand two or three times the quoted price. Novak Lock & Security is contractually prohibited from this practice. The price we quote is the price on the invoice. We also offer a Free Second Opinion on Any Written Estimate - bring us a competitor’s quote and we will review it at no charge.
Your free estimate includes a full inspection of your existing hardware, measurement of door and frame, and a written scope with line-item pricing. There is no call-out surcharge added on arrival. The full price is quoted on the phone before anyone is dispatched, and it is the price on the invoice.

Frequently Asked Questions - Lock Installation & Rekey in Marietta
Lock installation replaces your existing lock hardware with new components; rekeying changes the internal pin configuration of your existing lock so old keys no longer work while the hardware stays in place. Rekeying is faster and less expensive when your hardware is in good condition. Installation is necessary when hardware is damaged, outdated, or when you want to upgrade security grade or features.
A standard rekey takes 20-30 minutes per door. A straightforward deadbolt installation takes 30-45 minutes. Smart lock installations run 45-90 minutes depending on network setup and user training. We schedule appointments with arrival windows, not “sometime today” vagueness, and we call 15 minutes before arrival.
