Fast, Reliable Lock Installation & Rekey Across Manassas
Lock installation and rekeying in Manassas splits into two very different jobs: quick tenant-turnover rekeys in the Route 28 corridor’s 1980s-2000s townhome communities, and specialty work on Old Town’s original mortise hardware that a modern deadbolt simply won’t replace. Most rekeys run $25-$40 per cylinder, standard deadbolt installation runs $85-$160 per lock, and every price is quoted in writing before a single screw is turned. If you live anywhere from Sudley Road to the Manassas VRE station lots, our Lock Installation & Rekey team can be at your door quickly, with a documented record left behind when we’re done. Call (331) 310-8471 and a live person answers, not a voicemail queue.
Why Novak Lock & Security Is Manassas’s Preferred Lock Installation & Rekey Company
We work the full span of Manassas, from 1990s townhome rows off Sudley Road to the storefronts on Center Street in Old Town, and the jobs rarely look alike. In the townhome communities, we’re typically rekeying original Kwikset deadbolts after a tenant moves out and the property manager can’t account for every key copy. In Old Town, we’re more likely rebuilding a Schlage mortise lock body on a door that’s been swinging for decades. Our techs know the difference because they’ve stood in both doorways.
Daniel Novak founded this business in 2002 on a rule that hasn’t changed: the price quoted on the phone is the price on the invoice. That’s Haven Standard Clause 1, and it applies to every lock installation, every rekey, every emergency call in Manassas. Uniformed, background-checked technicians do the work, and every visit ends with a photo record - what we found, what we did, what the hardware looked like after. No exceptions, no “we’ll see when we get there.”
Manassas homeowners tend to research before they call. They read the three-star reviews. That’s why we put ranges in writing here and on the phone, and why we’ll review any competitor’s written estimate at no charge before you commit to anything.
Our Lock Installation & Rekey Services in Manassas

Smart Lock Installation
A smart lock on a 1980s colonial door in Manassas is not a drop-in job. The original builder-grade deadbolts were installed in doors that have since warped slightly from two decades of humid summers and hard freezes, and a new smart latch will bind if the strike plate isn’t realigned first. We handle that alignment, and we’re careful about placement: north- and east-facing entries in Manassas take the brunt of condensation during sharp temperature swings, which shortens the life of a keypad that’s mounted where frost and moisture collect. Smart lock installation in Manassas typically runs $150-$300, including the labor to make the existing door work with the new hardware, not just screw it on.

Keyless Entry & Keypad Lock
Keypad entry systems make sense for Manassas rentals with frequent turnover - property managers avoid rekeying every six months by changing the code instead. But the keypad itself has to survive genuine winter freezes. The inland location means Manassas sees harder freezes than closer-in NoVA suburbs, and a poorly weather-stripped townhome door will let moisture into the cylinder behind the keypad. We install keypads with sealed battery compartments and reposition weather stripping where it’s failing. Keyless entry and keypad lock installation in Manassas runs $120-$250 per door, quoted in writing before work starts.

Biometric Lock Installation
Biometric locks - fingerprint or keypad-plus-bio combinations - are common requests in Manassas’s newer builds and in homes where owners want to eliminate physical keys entirely, usually because a rental turned over and too many copies of the original key exist. The same door-fit considerations apply: a biometric deadbolt needs a clean strike plate alignment and a battery compartment that won’t fail during a hard freeze. We install biometric hardware from brands including Baldwin and Mul-T-Lock, and we calibrate the fingerprint reader on-site so it works reliably in cold, damp conditions. Biometric lock installation in Manassas runs $200-$400 depending on hardware grade.

Key Duplication
Key duplication in Manassas is a two-tier service. Standard KW1 Schlage and Kwikset blanks can be cut at a hardware counter, but many of the townhome communities off Route 28 use restricted or master-keyed systems where a copied key must come from the locksmith who controls the keyway. If your key says “Do Not Duplicate” or the blank isn’t stocked at big-box stores, we can cut it from the original and verify it works in the cylinder before we hand it over. Standard duplication is $3-$8 per key; restricted keyway duplication requires confirmation of ownership and documentation, per the lock manufacturer’s policy.

Trusted Brands We Service in Manassas
We’re factory-authorized on Medeco, Mul-T-Lock, Abloy, Baldwin, and Schlage - the full range from builder-grade cylinders to high-security keyways that can’t be duplicated without a registered key card. For Manassas homeowners, that matters most when a landlord association specifies a particular brand, or when an Old Town property’s historic hardware needs a modern cylinder with a restricted blank. We stock the common parts locally for Manassas jobs, so a rekey or cylinder swap doesn’t wait on a warehouse shipment.
Common Lock Installation & Rekey Problems We See in Manassas Homes

- Unaccounted key copies after tenant turnover. Original Kwikset hardware from the 1980s and 1990s used widely shared key blanks, and after multiple tenants, a property manager usually has no idea how many copies exist. Rekeying the cylinder replaces the pins, but if the cylinder itself is still the original builder-grade part, it remains vulnerable to key-bumping - common on townhome rows where walls are shared and bump attacks take seconds.
- Moisture-seized deadbolts during hard freezes. Manassas sits far enough inland to get real winter freezes, and the humid summers mean moisture works into pin-and-tumbler cylinders on doors with failing weather stripping. The result is a deadbolt that turns sluggishly or seizes entirely at the exact moment a commuter is rushing to catch the VRE into DC.
- Warped doors on 1980s colonials. A smart lock or high-security deadbolt installed on a door that has warped will bind the latch. We realign the strike plate before installing new hardware, and we tell you honestly when the door itself needs work first.
- Original mortise hardware in Old Town structures. Late-19th and early-20th-century buildings on Center Street and nearby often still have mortise lock bodies that a modern deadbolt won’t replace without destroying the door’s integrity. We rebuild the lock body, install a fresh cylinder, and preserve the door - which is the only correct approach in a historic district.

FAQs - Lock Installation & Rekey in Manassas

Yes, a standard Kwikset cylinder rekey runs $25-$40 and replaces the internal pins so old keys stop working. But know this: if the lock body itself is the original builder-grade part, the hardware is now around 30 years old, and a rekey doesn’t fix worn springs, loose tailpieces, or the fact that older Kwikset cylinders are relatively easy to bump. Many Manassas renters rekey immediately on move-in for basic key control, and we’re happy to do that. Just ask yourself whether you also need a better cylinder while we’re there. Call (331) 310-8471 and we’ll tell you straight what condition the lock is in.
Rebuild it. A mortise lock body in an Old Town Manassas door is part of the door’s structure, and drilling out the door face to force a modern deadbolt into that space weakens the whole assembly and typically violates historic district expectations. We rebuild the lock body, install fresh pins in the cylinder or replace the cylinder with a keyed-alike or restricted-keyway option, and the door stays intact. Typical cost runs $150-$400 depending on what’s worn. Call (331) 310-8471 for an exact quote on your specific hardware.
It’s not that your neighbors’ specific keys open your door - it’s that the original Kwikset cylinders installed in these 1980s-2000s townhome communities used a relatively small number of key bitting combinations, and the blanks are broadly shared across the KW1 keyway. That means cross-keying isn’t rare, and it gets worse when multiple tenants over 30 years all held copies. The fix is a rekey to a new keyed-alike system, and ideally an upgrade to a bump-resistant high-security cylinder. Rekey pricing in Manassas starts at $25-$40 per cylinder; high-security cylinders from brands like Mul-T-Lock run more. Call (331) 310-8471 and we’ll walk you through the difference.
Usually yes, but the door work happens first. A 40-year-old colonial door in Manassas has gone through four decades of humid summers and hard freezes, and the door frame has shifted. A smart lock’s motorized bolt has tighter tolerances than an old mechanical deadbolt, so any misalignment binds the latch and kills the battery faster. We realign the strike plate, check the weather stripping, and only then install the smart lock. Smart lock installation in Manassas runs $150-$300 including that fit work. Call (331) 310-8471 for a written quote on your door.
A rekey is the affordable baseline - $25-$40 per cylinder replaces the pins so all previous copies stop working - and if the lock body is still in good shape, that’s all you need. But if your unit is in a Route 28 townhome community with original 1990s Kwikset hardware, you’re also dealing with a cylinder that’s known to be bump-prone and a key blank that’s shared across thousands of units. For Manassas rental properties with recurring turnover, we often recommend a keyed-alike high-security cylinder upgrade so every future tenant change costs one rekey and the keyway can’t be duplicated at a hardware counter. Call (331) 310-8471 and we’ll give you a written price for either path.
