Fast, Reliable Lock Installation & Rekey Across Sunset Park
Lock installation and rekeying in Sunset Park means working on two very different kinds of hardware, often on the same block. A typical rekey for a standard door lock in Sunset Park runs $95-$160, and full lock installation typically lands between $180-$420 depending on the hardware. Our technicians arrive at row houses on 5th Avenue with replacement parts for 1890s-1920s mortise keyways, then cross 3rd Avenue to Industry City and install commercial-grade access control in converted studio spaces. Call (331) 310-8471 and a live person answers, 24 hours a day.
Why Novak Lock & Security Is Sunset Park’s Lock Installation & Rekey Company
Since 2002, Novak Lock & Security has operated under a rule that most locksmith companies won’t put in writing: the price quoted on the phone is the price on the invoice. Haven Standard Clause 1 exists because the trade has a well-earned reputation for bait pricing. Our dispatchers quote firm numbers before any tech is dispatched, and our technicians are not permitted to change that number at the door. It has been that way for over two decades.
Every tech who arrives in Sunset Park is background-checked and uniformed. They hand you a written scope before touching a cylinder, and they leave a documented photo record at the end of the job. That record shows what they found, what they did, and the condition of the hardware when they left. Daniel Novak built the company on the idea that a real name goes on the van and the invoice, and the paperwork proves the work. For Sunset Park tenants and owners, that matters because the person paying for the rekey is often not the person who owns the door. We keep the freeholder’s original hardware intact and document that we did.
Our Lock Installation & Rekey Services in Sunset Park

We handle the full range of Lock Installation & Rekey work across Sunset Park, from original mortise lock rebuilds in brick row houses to keypad and biometric systems in converted commercial space. Four sub-services matter most in this neighborhood.
Smart Lock Installation in Sunset Park
Smart lock installation in Sunset Park usually runs $220-$520 per door, including the lock and the site survey. The challenge here is the door itself. An 1898 row house on 48th Street has a thick wooden door stile and a mortise cut that was never designed for a modern deadbolt or a Yale smart lock assembly. We do non-destructive retrofits: we measure the existing mortise pocket, install an adapter plate where needed, and mount the smart lock so the freeholder’s door frame is not drilled out. For renters, we install tenant-friendly options that mount over the existing hardware and can be removed without a trace.

Keyless Entry & Keypad Lock Installation in Sunset Park
Keypad lock installation in Sunset Park typically costs $180-$380 per door. Ground-floor units in two- and three-family houses almost always have two entry points: the inner wooden door and an outer iron security gate with its own deadbolt and padlock hasp. A keypad only on the inner door is half a job. We keypad both barriers or specify a gate-specific model that survives salt-laden air within a few blocks of Upper New York Bay. For multi-tenant buildings along 7th and 8th Avenues, we install keyless entry with individual user codes so each resident gets their own access, and codes can be deleted when someone moves out without changing the physical cylinder.

Biometric Lock Installation in Sunset Park
Biometric locks run $320-$700 installed in Sunset Park. These are a practical choice for Industry City studios and small-business units where multiple employees or tenants need audited entry records. A fingerprint or keypad-based biometric system logs every unlock event, which is exactly what a converted waterfront workspace owner on 2nd Avenue needs when they can’t physically track who’s entering a shared studio suite. Our factory-authorized work covers Baldwin, Yale, and high-security Mul-T-Lock cylinders paired with biometric hardware.

Key Duplication in Sunset Park
Standard key duplication in Sunset Park starts at $3-$8 per key. Restricted and high-security keys from Medeco or Mul-T-Lock run $15-$45 per key and require owner authorization. This matters in two- and three-family houses near 52nd Street: a first-floor tenant who copies their key at a generic shop on 8th Avenue often gets a duplicate that jams the mortise cylinder, and every extra working copy in circulation weakens the building’s security. We cut bump-resistant keys on-site and can key the building so each unit’s key opens only that unit’s locks plus the common entry.

Trusted Brands We Service in Sunset Park
We work on the locks actually found in Sunset Park: original mortise sets from the 1890s-1920s that most shops can’t identify, plus Medeco and Mul-T-Lock high-security cylinders on commercial doors, and Baldwin and Yale hardware on newer replacements. Our stock includes mortise lock bodies, faceplates, and strike plates for obsolete keyways that big-box stores stopped carrying years ago. For waterfront-adjacent units, we stock corrosion-resistant deadbolts and marine-grade lubricants specifically because the salt air off Upper New York Bay is harder on cylinders than anything inland Brooklyn sees. When you need a part, we have it in the van, not on backorder.
Common Lock Installation & Rekey Problems We See in Sunset Park Homes

- Drilled-out original mortise locks. A previous tech takes a drill to an 1890s mortise lock because they don’t carry the parts. The thick wooden door stile is now damaged, the freeholder’s antique hardware is destroyed, and the resident is stuck with a $600+ custom repair or full door replacement. We repair the mortise lock body with replacement parts we keep for these keyways, and the door is untouched.
- Iron security gates treated as an afterthought. Ground-floor units across Sunset Park have an outer gate with its own deadbolt and padlock hasp. A tech who rekeys only the inner door leaves the resident unable to use the gate, or locked out at the second barrier. We always key the gate and the door together, and we quote both in writing before starting.
- Corroded pin-and-tumbler cylinders near the waterfront. Units on 1st and 2nd Avenues and side streets closer to the water see cylinders seize and deadbolts freeze years before the same hardware would fail in Borough Park. This is salt-laden air, not bad luck. Our rekey service includes disassembly, cleaning, and lubrication of the existing cylinder so the new key’s pins aren’t grinding against corrosion in six months.
- Non-standard keyways from the 8th Avenue corridor. Along the 8th Avenue Chinese business corridor, shop owners often install disc-detainer padlocks and multi-point door locks with cylinder profiles that appear in no American lock catalogue. We encounter these brands regularly and can service or open them without destruction, because we’ve seen them before.

FAQs - Lock Installation & Rekey in Sunset Park

We rekey an original mortise lock without drilling by disassembling the lock body in place, extracting the old cylinder, and repinning or replacing the internal tumblers using parts sized for that era’s keyway. Our rekey of an antique mortise lock in a Sunset Park row house typically runs $120-$200 and leaves the door stile and the freeholder’s original lock body intact. On a call near 8th Avenue and 52nd Street, our tech arrived at a two-family brick row house with a frozen mortise lock on the ground-floor unit’s original wooden door. The salt-laden air from Upper New York Bay had corroded the pin and tumbler cylinder and deadbolt faceplate. We used non-destructive entry, rebuilt the mortise lock body with replacement parts we keep for 1890s-1920s keyways, and cut new bump-resistant keys on-site so the tenant could rekey without replacing the freeholder’s original hardware. Call (331) 310-8471 and we’ll quote the rekey over the phone before anyone is dispatched.
Your deadbolt seizes because the salt-laden air off Upper New York Bay corrodes the pins and cylinder interior faster than normal, so the lock fails during temperature swings that would not affect the same hardware further inland. Lock rekey and cylinder cleaning in Sunset Park costs $95-$160 per cylinder, and for waterfront-adjacent units we include disassembly, internal cleaning, and application of a marine-grade lubricant so the rekeyed cylinder does not seize again in the next cold snap. The fix is not a new deadbolt; it is proper cylinder maintenance plus a corrosion-resistant faceplate if yours has pitted. We see this pattern constantly on 1st and 2nd Avenue units where the same lock would last another five years in Flatbush. Call (331) 310-8471 for an exact quote, and the price you get is the price on the invoice.
Yes, we install smart locks on Sunset Park apartment doors with original mortise lock bodies, but we do the work without drilling out the freeholder’s wooden door stile. The smart lock gets mounted using an adapter plate that fits the existing mortise pocket, and we key the outer iron security gate to match so both barriers work together. Smart lock installation in Sunset Park runs $220-$520 per door, including the adapter work and programming. For tenants, we recommend a model that mounts over the existing hardware so it can be removed cleanly when the lease ends. We’ll also key the gate’s padlock hasp on ground-floor units when we install the smart lock, because a smart lock on the inner door with an old brass padlock on the outer gate is not a functioning entry system. Call (331) 310-8471 for a written quote, and the number does not change at the door.
The fastest non-destructive way back into a Sunset Park ground-floor unit is to call a locksmith who carries mortise lock parts and picks the cylinder open rather than drilling the door. We respond to Sunset Park lockouts around the clock, and our techs arrive prepared for thick wooden row house stiles and obsolete keyways, which means the entry is non-destructive and the freeholder’s original hardware is preserved. Standard lockout response in Sunset Park runs $95-$180 depending on time and equipment, quoted in writing before dispatch. Drilling is a last resort we rarely use here, because destroying an 1890s mortise lock means a custom repair and a door the landlord now has to replace. Call (331) 310-8471 day or night and a live person answers. The price is quoted before anyone comes to 4th Avenue or 52nd Street.
Rekeying prevents a copied-key problem by changing the cylinder’s internal pins so all previously made copies stop working, while the original keys still operate the lock after we cut new ones. Rekeying a two- or three-family Sunset Park house costs $95-$160 per cylinder for standard locks and $120-$200 per cylinder for original mortise locks. We can also key the building so each unit’s key only opens that unit plus the common entry, which means a former tenant’s copy no longer turns any lock in the building. This matters especially on blocks near the 8th Avenue corridor where casual key duplication is easy and the turnover of tenants in attached brick row houses is constant. Call (331) 310-8471 for a building rekey quote in writing, and the price is firm before any work starts.
If you need a lock installed or rekeyed in Sunset Park today, call (331) 310-8471. A live person answers 24 hours a day, quotes a firm price in writing before dispatch, and every job is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right.
