Trusted Lock Installation & Rekey for Ashburn Homeowners
Lock installation and rekey in Ashburn typically costs $95-$285 per door depending on hardware grade, and most jobs are completed in a single visit with a written price confirmed before we start. Novak Lock & Security Ashburn has installed or serviced over 60,000 locks, keys, and security systems since 2002, every one with a documented photo record and a price fixed under Haven Standard Clause 1. Call (571) 410-8874 for a firm quote from a live dispatcher, 24 hours a day.
Most Ashburn homeowners who call us bought their house between 2015 and 2020. They have Kwikset or Schlage builder-grade deadbolts, a smart lock on the front door that stopped responding after a firmware update, or a side door that was never rekeyed after the previous owner lost track of how many keys were copied. We see the same hardware patterns across Lock Installation & Rekey in Ashburn, Lock Installation & Rekey in Herndon, and Lock Installation & Rekey in Leesburg, and we stock the cylinders, tailpieces, and adapters that let us finish the job without a second trip.
Daniel Novak built this operation on one rule: the price quoted on the phone is the price on the invoice. The technician cannot change it. This is not a courtesy. It is Haven Standard Clause 1, in force since 2002, and it is why we do not operate like the call centers that quote $19 and invoice $340.
What Our Lock Installation & Rekey Service Includes
Smart Lock Installation
Smart locks are battery-powered deadbolts or levers that connect to Wi-Fi, Z-Wave, or Bluetooth for remote access, scheduling, and user-code management. In Ashburn we install them most often on front doors of townhomes in Loudoun Valley Estates and single-family homes near Ashburn Village, where homeowners want to drop a contractor code at 5 PM and delete it at 6. We verify door thickness, backset, and existing bore hole alignment before quoting, because retrofitting a 2-1/8″ smart lock into a 1-1/2″ legacy door requires a different mounting kit and labor scope. We document the voltage check, the strike alignment, and the app pairing with a photo record left with you at completion.

Keyless Entry
Keyless entry systems replace mechanical key operation with PIN, fob, or card credential, common on side doors, home offices, and basement utility rooms in Ashburn’s older sections near Farmwell Road. We install standalone battery units and hardwired systems with audit-trail capability, depending on whether you need a simple code lock or a log of who entered and when. Our technicians carry the Schlage and Baldwin keyless lines in the van, plus retrofit plates for doors with non-standard prep. Every installation includes a written scope noting door handing, strike depth, and whether the frame requires reinforcement.

Keypad Lock
Keypad locks are the mechanical or electronic push-button entry devices found on pool gates, garage man-doors, and rear entries throughout Ashburn’s planned communities. We see a lot of weather-faded mechanical keypads in Brambleton that still function but have lost their combination confidentiality after a decade of service, and we replace them with marine-grade electronic units rated for Northern Virginia humidity swings. The labor varies: a surface-mount keypad on a wood gate takes 45 minutes; a mortised keypad in an aluminum frame requires routing and a custom strike. We name both scenarios and their prices before we start.

Biometric Lock
Biometric locks use fingerprint or facial-recognition authentication, most often requested for wine rooms, gun safes, and home offices in Ashburn’s newer construction near One Loudoun. We install fingerprint-enabled deadbolts and standalone cabinet locks from manufacturers including Schlage and Baldwin, and we calibrate enrollment for multiple users with varying print quality. The critical detail is power source and backup: we specify whether the unit runs on AA batteries, hardwired low voltage, or both, and we document the mechanical override key location in your written record.

Electronic Lock
Electronic locks encompass hardwired access-control electrified hardware, battery-powered motorized deadbolts, and hybrid systems that bridge residential and commercial-grade security. In Ashburn we install electronic locks on home-based business entrances, ADU separate dwellings, and rental properties where the owner needs remote rekeying capability without changing the cylinder. Our scope includes power supply location, wire routing for hardwired units, and battery-life projection for wireless models. We are factory-authorized on Medeco, Mul-T-Lock, Abloy, and Schlage electronic lines, and we stock the proprietary programming tools that prevent a return visit.

Key Duplication
Key duplication is the precision cutting of a working key from an original or code, performed on-site or at our shop for standard, high-security, and restricted-keyway blanks. Ashburn homeowners bring us worn originals from 1990s-era Baldwin sets, Medeco milled keys with angle cuts that require a dedicated duplicator, and broken Schlage keys extracted from locks we then rekey to a new combination. We verify the blank by sight and by code book, cut on calibrated machines, and test in your lock before you pay. High-security duplication requires card authorization; we process this while you wait if the credential is present.

Brands We Service for Lock Installation & Rekey

We are factory-authorized for Mul-T-Lock, Sargent, Abloy, and Schlage, and we maintain direct distributor relationships for parts availability and warranty registration. For Mul-T-Lock we stock the Interactive+ and MT5+ high-security cylinders, the cam adapters for retrofit into Schlage and Kwikset housings, and the proprietary key-duplication cards required for authorized copies. We have serviced hundreds of Mul-T-Lock units in Northern Virginia and can rekey an existing cylinder or install a new one with a fresh key system in a single visit.
Schlage is the most common brand we encounter in Ashburn residential work, from the entry-grade Plymouth and Camelot lines to the B660P commercial deadbolt and the Sense smart lock. We carry the full range of Schlage cylinders, latch assemblies, and smart-home bridge modules, and we have the Schlage Connect programming app on every technician’s tablet. For Sargent and Abloy, our work is more specialized: Sargent 10-line mortise locks in commercial applications, Abloy Protec2 cylinders for customers who require pick-proof, bump-proof, drill-resistant hardware. Whether you have these brands or any other make, we can source parts, quote the repair or replacement in writing, and complete the work under the 365-Day Done Right Promise.
Signs You Need Lock Installation & Rekey Right Now
- The key sticks, catches, or requires jiggling. This indicates worn pin chambers, a bent key, or internal corrosion from Ashburn’s seasonal humidity shifts. A sticky lock does not fix itself; the wear accelerates until the key breaks off or the cylinder seizes entirely. We can rekey the cylinder with fresh pins and cut a new key to factory spec, or replace the lock if the housing is damaged.
- You cannot account for all copies of your key. After purchase, after a roommate or contractor departs, or after a divorce, the number of unreturned keys is always higher than estimated. Rekeying changes the internal pin combination so old keys no longer operate the lock; it takes 20 minutes and costs a fraction of full replacement.
- The lock was part of a builder package installed in 2015-2018. Ashburn’s rapid construction during those years used grade-2 and grade-3 hardware chosen for cost, not longevity. We find Kwikset SmartKey housings with cracked cylinders, Schlage deadbolts with zinc castings that corrode at the set screw, and Baldwin units with tarnished finishes that no longer match the door. Replacement with grade-1 hardware is a permanent fix.
- Your smart lock displays a low-battery warning weekly or loses connectivity. Frequent battery drain indicates a failing motor, poor Wi-Fi signal strength at the door, or a firmware conflict with your hub. We diagnose the root cause with a voltage load test and signal-strength meter, then quote repair or replacement with a unit matched to your network architecture.
- The deadbolt does not fully extend into the strike plate. Misalignment from seasonal frame movement, foundation settling common in Ashburn’s clay-heavy soils, or improper original installation leaves the bolt riding the strike lip. This is not a minor issue; a deadbolt that does not seat is a deadbolt that can be forced with a screwdriver. We adjust, reposition, or replace the strike and test for full throw.
Our Lock Installation & Rekey Process - Step by Step

- 1
Phone diagnosis and written quote. When you call (571) 410-8874, a live dispatcher answers. We ask for lock brand, symptoms, door material and thickness, and whether you have the original key. We quote a firm price range, explain what could shift it (hidden damage, non-standard prep), and schedule a window. Haven Standard Clause 1 applies: the price on the phone is the price on the invoice.
- 2
On-site inspection and confirmation. The technician arrives in a marked van, in uniform, with a background-check credential available on request. We inspect the lock, verify the quote conditions, and confirm the price in writing before touching tools. If we find unexpected damage, we stop, explain, and quote the revision; you approve or decline.
- 3
Service execution with documentation. We perform the installation, rekey, or repair using calibrated tools: pin kits with .003″ tolerance for rekeying, mortise gauges for door prep, torque drivers for strike screws. Every step is photographed: the existing condition, the work in progress, the finished installation, and the tested operation.
- 4
Testing and customer verification. We cycle the lock 10 times, test all keys or credentials, verify smart-lock connectivity if applicable, and have you operate the hardware yourself. We do not leave until you confirm satisfaction and sign the digital work order.
- 5
Written record delivery and warranty registration. You receive a printed or emailed summary: the work performed, parts used, before-and-after photos, the technician’s name and ID, and the 365-Day Done Right Promise terms. For brand-authorized work, we register your warranty with the manufacturer and forward the confirmation.
How Much Does Lock Installation & Rekey Cost in Ashburn?
A standard residential rekey in Ashburn runs $95-$145 per cylinder, including new pins, two keys, and the service call. Lock installation ranges $145-$285 per door for grade-2 deadbolts and levers, with grade-1 commercial hardware or smart locks at $285-$495 depending on prep complexity and connectivity requirements. Key duplication is $4-$18 per key for standard blanks, $25-$65 for high-security restricted keys with card authorization.
| Service | Typical Range in Ashburn | What Affects Price |
|---|---|---|
| Residential rekey (per cylinder) | $95-$145 | Cylinder type, key quantity, after-hours scheduling |
| Deadbolt or lever installation (grade 2) | $145-$285 | Door prep condition, strike alignment, hardware grade |

What moves the price: door material (steel requires carbide bits, fiberglass needs backing plates), existing damage that must be repaired before new hardware mounts, and the difference between a simple swap and a full mortise installation. We do not add a “trip charge” or “diagnostic fee” after arrival. The quote includes everything.
To avoid overpaying, get any competitor’s estimate in writing and bring it to us for a free second opinion. We will itemize the scope, identify missing components or inflated labor, and quote our equivalent work. There is no obligation.
