Residential Locksmith Services in New York & the New York area

Being locked out of your house is stressful, but the process on our end is calm and methodical. When you call 646-793-9435, we ask a few quick questions: your location, the type of door and lock you have, and whether you're locked out of your house with no key at all or simply missing the right one. That lets us send the right technician with the right tools, whether you're in a walk-up near Riverside Park or a doorman building off Broadway. Most calls in central Manhattan get a fast local mobile response because our vans are already moving through the neighborhood.

On arrival, our technician will verify that you're authorized to enter the home before any work begins — a photo ID with the address, a lease, a mail piece, or a neighbor or building staff who can vouch for you. This ownership check protects you and everyone in the building, and it's standard practice for any legitimate emergency locksmith. Once that's settled, we assess the lock. For most standard cylinders and even many a stubborn mortise lock, we can perform damage-free entry, meaning your hardware stays intact and you don't pay to replace a broken lock afterward.

We'll always tell you what to do if you're locked out of your house before we start: check for a spare with a trusted neighbor, try a back or garden entrance if you have one, and confirm no windows were left accessible. If none of that works, we open the door, get you inside, and — if your key was lost or stolen — we'll talk through rekeying or a lock change so a missing key can't be used against you later. You get an exact quote up front, every time, with no surprises added at the end.

A huge share of New York apartments, especially the pre-war buildings lining West End Avenue, Central Park West and Riverside Drive, still run on a mortise lock — the heavy, box-style mechanism set into the edge of the door rather than bolted onto the surface. A well-maintained mortise lock is genuinely strong, but decades of use wear out the internal parts, and a sticking or grinding cylinder is often the first warning that yours is due for service. We repair, rekey and upgrade mortise hardware, and we stock cylinders that fit the odd sizes common in older Manhattan doors.

If you're upgrading, a high-security deadbolt is one of the best investments you can make at your front door. These use restricted keyways and hardened internal components that resist the drilling and manipulation that ordinary hardware can fall to. We install trusted brands like Schlage and Medeco, and for buildings that require the original look, we can pair a modern security cylinder with your existing mortise body so it still matches the door. A worn door knob lock on a secondary entrance is easy to overlook, but it's a weak point worth addressing at the same time.

Choosing between a rim cylinder, a mortise cylinder and a full high-security system depends on your door, your building's rules, and how much control you want over key duplication. Our technicians walk you through the trade-offs honestly and never push hardware you don't need. Whatever you choose, we confirm the price before the work starts. Call 646-793-9435 and we'll assess your door and recommend the right level of protection for how you actually live.

Smart lock installation has moved from novelty to genuinely practical, especially for busy New Yorkers juggling dog walkers, cleaners and guests. If you rent, the good news is that many keyless options don't require drilling or permanent changes: retrofit smart deadbolts replace only the interior thumb-turn while keeping your building's existing cylinder and key, so you get app and keypad access without violating your lease or losing your deposit. We install these cleanly and can reverse the change when you move out.

For owners and co-op residents who want more, we handle full smart lock installation including keypad deadbolts, fingerprint models, and even a mortise smart lock that drops into the same footprint as a traditional pre-war mortise body — a great fit for older Upper West Side and Harlem apartments where surface-mounted hardware looks out of place. We'll set up user codes, connect the lock to your Wi-Fi or building system where allowed, and show you how to add and revoke access for family, guests and service providers.

No smart lock is a substitute for a solid mechanical foundation, and we're candid about that. Battery backups, physical key overrides and a properly aligned strike all matter, and we test each one before we leave. If you want the convenience of keyless entry without giving up reliability, we'll build a setup that fits your door and your routine. Ask about a mortise smart lock when you call — it's one of our most popular residential upgrades in older buildings.

Rekeying is the smartest move any time a key is out of your control — after a breakup, a roommate moves out, a break-in, or a lost or stolen key. Here's how lock rekeying works: instead of replacing the whole lock, we open the cylinder, swap the internal pins to match a brand-new key, and any old key instantly stops working. It's faster and less costly than a full lock change because we reuse your existing hardware, and it's why so many people searching for rekey locks near me end up choosing it over replacement.

The step-by-step on our end is straightforward. We confirm you're authorized to change the locks, then remove and open each cylinder you want rekeyed. We reconfigure the pin stacks to a fresh key code, cut new keys on the spot, reinstall everything, and test every door and every key before we go. Many homes have several entry points keyed alike, so we can set all your doors to a single new key for convenience, or key them separately if you prefer. If you want to know how to rekey a lock yourself, be honest about the tools and patience involved — for security-grade and mortise cylinders, a trained hand gets it right the first time.

There are moments when rekeying isn't enough and a lock change makes more sense: cracked housings, obsolete hardware, or when you want to jump to a higher security tier. We'll tell you plainly which path fits your situation. Whether it's rekey a lock on a single apartment door or a full lock change across a townhouse, we quote the exact price before we begin. Call 646-793-9435 for same-day lock rekeying anywhere we serve.

Front doors get all the attention, but a determined intruder looks for the easiest way in, and in New York that's often a ground-floor window, a fire-escape window, or a sliding balcony door. We install and upgrade window locks, sash locks, keyed window stops and sliding-door bars, plus pin locks that stop a slider from being lifted off its track — a common vulnerability on older terrace and garden-level doors around Morningside Heights and the outer boroughs.

Secondary entrances deserve the same scrutiny. A basement door, a service entrance, or an interior door to a shared hallway may still be running a tired door knob lock that offers little real resistance. We can add a deadbolt, upgrade the strike plate with longer screws that bite into the door frame's stud, and reinforce the area around the latch — small changes that dramatically improve how a door holds up. These upgrades are quick, unobtrusive, and pay for themselves in peace of mind.

If you have children or aging family members, we also handle safety-focused hardware: thumb-turn deadbolts that don't require fumbling for a key in an emergency, and locks positioned to keep little ones from wandering out. We'll walk your home with you, point out the gaps, and recommend only what genuinely improves security. As always, you'll have an exact quote before any hardware goes in.

Real home security isn't one gadget — it's layers that each buy you time and deterrence. We think about it starting at the sidewalk and working inward: a solid front-door cylinder or high-security mortise lock, a reinforced strike and frame, secured windows and secondary doors, and then convenience layers like a smart lock or keypad for daily use. When those layers work together, casual attempts get discouraged and serious ones get slowed down enough to matter.

For co-op and condo residents, we also factor in your building's rules and shared systems. Many Upper West Side buildings restrict what you can install on the corridor side of your door, so we design around those constraints — sometimes keeping the building-approved exterior look while upgrading the internal mechanism and the interior side. We can key your apartment locks alike for simplicity, set up master-key arrangements for landlords with multiple units, and integrate a mortise smart lock where the aesthetic and security both need to hold up.

Beyond the front door, we can advise on intercom-linked locks, camera-friendly hardware and access schedules for anyone who comes and goes. Our technicians are trained, insured and experienced with both antique and cutting-edge systems, so nothing about your door is a mystery to us. Ready to tighten things up? Call 646-793-9435 — we answer 24/7 and can usually schedule a home security assessment the same week, or handle an emergency the same hour.
