Lock Installation & Rekey in Paterson: What It Costs & How It Works
Lock installation and rekeying in Paterson, NJ typically runs $85-$185 for a standard rekey (3-5 cylinders) and $150-$450 for new lock installation, depending on whether you’re dealing with modern deadbolts or the antique mortise locks found throughout this city’s pre-war housing stock. Most jobs are completed same-day, and Novak Lock & Security quotes a firm written price before we dispatch anyone. Call (331) 310-8471 and a live person answers, 24/7.
Paterson is not a suburban lock market. The city’s 1890s-1930s brick tenements, rowhouses, and converted silk mills present hardware challenges you simply don’t see in Clifton or Montclair. We’ve spent two decades working on Lock Installation & Rekey jobs here, and the difference comes down to one thing: in Paterson, a “routine rekey” frequently involves converting obsolete skeleton-key mortise locks to modern pin-and-tumbler cylinders across multiple units at once. That’s the job we’re built for.
Key Takeaways
- Standard rekey in Paterson: $85-$185 for 3-5 cylinders, quoted in writing before work starts
- New deadbolt or entry lock installation: $150-$450, including hardware
- Mortise-to-cylinder conversions on antique locks: $65-$110 per door, a Paterson specialty
- Same-day service across all Paterson neighborhoods, including the Eastside, Hillcrest, and South Paterson
- Every job includes a documented photo record and the 365-Day Done Right Promise
Fast, Reliable Lock Installation & Rekey Across Paterson

If you live in Paterson, you already know the drill: door frames shift with the seasons, skeleton keys go missing between tenants, and the deadbolt that worked fine in October suddenly binds in February. Our team knows Passaic County’s freeze-thaw cycles and what they do to century-old brick buildings. When you call (331) 310-8471, we’ll give you a firm price on the phone, tell you exactly when a technician can arrive in your neighborhood, and send a background-checked, uniformed locksmith with the right parts on the van.
We serve all of Paterson: the Eastside, Hillcrest, South Paterson, Lakeview, Riverside, Stoney Road, and the downtown corridors along Market Street and Main Street. Dispatch and scheduling are coordinated from our New York City office; crews are local to Paterson and know the buildings here. No call-center runaround. No bait pricing. The price you get on the phone is the price on the invoice, per Haven Standard Clause 1, and it’s been that way since 2002.
Why Novak Lock & Security Is Paterson’s Preferred Lock Installation & Rekey Company
Daniel Novak founded this company in 2002 with one rule: write the price down before touching a lock. That rule exists because Paterson’s lock market has a problem. Fly-by-night operations quote low over the phone, show up, and pad the invoice at the door. We do the opposite. The dispatcher quotes a price, the technician is contractually prohibited from changing it, and the customer keeps a written record of the job when we leave.
That discipline matters even more with Paterson’s housing stock. A landlord managing a 4-family brick tenement off Market Street doesn’t need a generic locksmith; they need someone who has converted worn skeleton-key mortise locks to Schlage pin-and-tumbler cylinders without damaging 1920s iron trim. They need someone who knows that shimming a strike plate in a racked frame is part of the job, not an add-on. Our technicians work to The Haven Standard, the same documented quality framework applied across all ten Haven brands, and every visit ends with a photo record of the work performed.
We’re factory-authorized for Medeco, Mul-T-Lock, and Baldwin, and we carry parts for older Schlage and Yale hardware still common in Paterson’s multifamily buildings. No subcontracting. No rotating cast of untrained help. Just locksmiths who know this city’s buildings.
Our Lock Installation & Rekey Services in Paterson

Smart Lock Installation
Smart locks work in Paterson, but the installation is different here than in a 2015 single-family build in Wayne. Many of our Paterson smart lock jobs involve retrofitting a keypad or Wi-Fi deadbolt onto a door that originally held a mortise lock. In some cases we install a smart deadbolt above the existing mortise lock; in others we convert the mortise lock to a modern cylinder and add the smart lock as the primary entry. Smart lock installation in Paterson typically runs $200-$450 including hardware, and we’ll tell you in writing whether your door frame can support the retrofit before you spend a dollar.

Keyless Entry & Keypad Locks
Landlords in Paterson’s 2-to-6-family buildings are the biggest adopters of keyless entry in Passaic County, and for a practical reason: between-tenant rekeying is a constant cost and security gap in a city with a high renter-to-owner ratio. A keypad lock lets you delete a former tenant’s code in 30 seconds without changing a single cylinder. Keypad lock installation in Paterson runs $180-$380 per door, including the lock, and we can key it to your existing master key system if you have one.

Biometric Lock Installation
Biometric locks, fingerprint and keypad combinations, are best suited to private entry doors, offices, and storage rooms in Paterson buildings where key control has failed repeatedly. We install them most often in medical offices near St. Joseph’s, retail back rooms along Market Street, and owner-occupied units in mixed-use buildings where multiple contractors need access without key copies floating around. Biometric lock installation runs $250-$550 per door depending on the lock grade and whether we’re retrofitting an existing mortise lock or cutting fresh hardware into an antique door. We stock Medeco and Yale biometric options and will quote the exact model in writing.

Key Duplication
Key duplication in Paterson is more complicated than the kiosk at the grocery store suggests. Standard keys are easy. But Paterson’s older buildings are full of restricted keyways, skeleton keys, and worn cylinders that a machine-cut copy will not reliably turn. We cut standard Schlage and Kwikset keys while you wait, and for restricted or high-security systems like Medeco and Mul-T-Lock, we’re factory-authorized to duplicate against verified owner credentials. No “we can’t do that here.” If you have the key and the authorization, we cut it.

Trusted Brands We Service in Paterson
We service and install the full spectrum: entry-grade Kwikset and Schlage, mid-range Yale, and high-security Medeco, Mul-T-Lock, and Baldwin hardware. Paterson customers with older brass mortise locks often ask whether their hardware is worth saving. Sometimes it is, sometimes it isn’t, and we’ll tell you which. We carry a rolling inventory of common cylinders, strike plates, and deadbolts for Paterson’s older buildings, so we’re not making a second trip because the 1940s mortise cylinder on the van didn’t match the one in your door. If you’re upgrading a multifamily building, ask about a keyed-alike or master key system from Medeco or Mul-T-Lock; they’re the two brands we recommend most for Paterson landlords who are serious about tracking key copies.
Common Lock Installation & Rekey Problems We See in Paterson Homes

- Freeze-thaw frame racking. Passaic County’s hard winter temperature swings cause Paterson’s century-old brick tenements to expand and contract, pushing door frames out of plumb. A deadbolt installed in October can bind or fail to throw by February unless the strike plate is shimmed and the frame is checked first.
- Skeleton-key mortise locks that a DIY rekey kit can’t fix. Many of Paterson’s older rental buildings still use lever-tumbler mortise locks with skeleton-key cylinders. A store-bought rekey kit often leaves the old skeleton-key warding in place, so a previous tenant’s copy still turns the lock or jams the cylinder. The actual fix is a full mortise-to-cylinder conversion.
- Shared entry doors that defeat key control. In a multi-unit building where several apartments share a common entry, rekeying only one unit’s lock is pointless if the old master key still opens the front door. A single missed door on a 6-family system can defeat the entire key control plan. We audit the whole system, not just the one cylinder.
- Worn wood door frames. Paterson’s attached rowhouses and tenements often have original wood doors with frames that have shifted, swelled, and been painted over for 80 years. Installing a new deadbolt in a frame that doesn’t sit plumb will work for a month and then fail. We realign or reinforce the strike plate as part of installation, not as an upsell.
Pricing for Lock Installation & Rekey in Paterson, NJ
Here are the numbers, in writing, the way we quote them over the phone:
| Service | Paterson Price Range |
|---|---|
| Standard rekey (3-5 cylinders, pin-and-tumbler) | $85-$185 |
| Mortise-to-cylinder conversion (per door) | $65-$110 |
| New deadbolt installation (hardware included) | $150-$280 |

| High-security cylinder upgrade (Medeco/Mul-T-Lock) | $120-$220 per cylinder |
These ranges reflect Paterson’s actual market and housing stock. A standard rekey in a modern apartment near St. Joseph’s is cheaper than a mortise conversion in a 1920s brick tenement off Main Street. The price we quote on the phone is the price on the invoice, and there is no call-out surcharge added on arrival. If you have a written estimate from another locksmith, bring it to us: we’ll review it at no charge. Call (331) 310-8471 for an exact quote before anyone is dispatched.
One Job That Explains Paterson Lock Work

In the Eastside neighborhood, a landlord managing a 4-family brick tenement off Market Street called us after a problem tenant left without returning keys. Our technician converted each unit’s worn skeleton-key mortise lock to a Schlage pin-and-tumbler cylinder, cut a new master key system for the owner, and reinforced the sagging strike plates on all four wood doors. The entire job was finished with non-destructive entry and zero new hardware on the exterior, so the 1920s iron trim stayed intact. That’s the Paterson difference: a rekey job that would take 45 minutes in a newer Clifton townhouse becomes a multi-hour, multi-door project requiring real craft and real experience with antique hardware.
And that’s exactly what this page exists to explain. Paterson’s century-old brick tenements and skeleton-key mortise locks change the scope of a lock installation or rekey. A generic guide or a suburban locksmith never encounters this volume of antique mortise hardware, and most price it wrong. We don’t. When you call Lock Installation & Rekey in Paterson, you’re not explaining your building to a technician who’s never seen it. You’re talking to someone who has seen four just like it this month.

FAQs - Lock Installation & Rekey in Paterson
Most of Paterson’s 2-to-6-family brick tenements were built between 1890 and 1945 with lever-tumbler mortise locks and skeleton-key cylinders, and many landlords simply never upgraded because the old system “still worked.” Yes, we rekey them, but not with a DIY pin swap. Skeleton-key mortise locks require conversion to modern pin-and-tumbler cylinders before they can be rekeyed to a new operating key. We do those conversions every week in Paterson, typically at $65-$110 per door. Call (331) 310-8471 for a firm written quote.
Not necessarily, but you do need to change every lock the former tenant could access, and in Paterson’s older buildings that often means more than the apartment door. If your building uses a shared master key or a common entry door with a skeleton-key system, a single missed door can defeat the entire key control plan across all six units. We audit the whole system and quote a written price for exactly what needs to change. Rekeying a 6-unit building typically runs $400-$900 depending on how many common doors are involved and whether mortise conversions are required. Call (331) 310-8471 and a live person will walk you through it.
In Paterson, it’s usually the building. The hard freeze-thaw cycles in Passaic County cause century-old brick door frames to rack and heave seasonally, which pushes deadbolt throws out of alignment with the strike plate. The lock itself is often fine. The fix is to shim the strike plate and realign the frame, which we do as part of any lock installation or rekey in Paterson. If the deadbolt is genuinely worn out, we’ll quote replacement in writing before touching anything.
Most Paterson mortise locks can support a keypad or smart lock, and there are two common approaches. We can convert the existing mortise lock to a modern cylinder and then install a smart lock as the primary entry, or we can install a keypad deadbolt above the existing mortise lock and leave the original hardware in place for aesthetics. The right approach depends on the condition of the door, the frame, and the existing mortise lock body. Most keypad retrofits in Paterson run $180-$380 per door including the lock. We quote the exact setup in writing before we order parts.
By converting the cylinder, not by butchering the door. We remove the old skeleton-key or worn cylinder from inside the mortise lock body, install a modern pin-and-tumbler cylinder that fits the existing mortise case, and cut new keys. The exterior trim, escutcheon plates, and iron hardware stay intact. That’s exactly how we handled the 4-family tenement off Market Street described above: non-destructive entry, zero new exterior hardware, and the 1920s iron trim untouched. The process is standard for us in Paterson’s older buildings, and it’s covered by the 365-Day Done Right Promise. Call (331) 310-8471 for a written estimate.
