Apartment Rekeying & Lock Changes
Moving into a new apartment on the Upper West Side, swapping out a roommate in Astoria, or realizing your keys are gone somewhere between the L train and your front door — these are everyday New York situations that call for an immediate, smart security response. The locks on your door carry the history of every tenant, sublet, and contractor who ever held a copy of those keys. Rekeying or changing your locks resets that history entirely, giving you genuine peace of mind that only you control who enters your home.

Why Apartment Rekeying & Lock Changes Matter More in NYC
New York City apartment turnover is relentless. Buildings in neighborhoods like Washington Heights or Crown Heights can cycle through dozens of tenants over the life of a single mortise lock cylinder. Every previous tenant, their partner, their dog-walker, and their subletter may still have a working key. New York law does not automatically obligate landlords to rekey between tenants unless specified in the lease — which means the responsibility often falls on you. Rekeying your lock immediately after move-in is one of the highest-return security decisions you can make, and it costs a fraction of what a break-in, stolen property, or identity theft incident will.
A roommate departure creates a similar vulnerability. Even if the relationship ended on good terms, a missing or unreturned key represents an uncontrolled point of entry. Our experienced technicians can rekey your existing cylinder so that every old key — including copies made at hardware stores — is rendered permanently useless, while new keys cut to the fresh pin configuration are handed directly to you. No lock replacement required in most cases, which preserves your door hardware and gets the job done efficiently.
Mortise Lock Rekeying, Door Knob Lock Service & Full Apartment Lock Changes
New York City apartments are famous for their variety of lock hardware, and our technicians are trained to work across all of it. The mortise lock is the workhorse of NYC residential security — a rectangular body that fits into a pocket (the 'mortise') cut into the door edge, combining a deadbolt and latch into a single, robust unit. Mortise lock rekeying requires removing the cylinder, disassembling the pin stack, and re-pinning it to a new key configuration. It's precise work that demands proper tools and hands-on experience; our technicians handle mortise lock service daily across the city's pre-war and post-war building stock. Beyond the mortise lock, we also service door knob locks, rim cylinders (the kind common on older Brooklyn brownstones), deadbolt cylinders, Medeco high-security cylinders, Schlage, Kwikset, and multi-point locking systems found in newer Manhattan high-rises.
When rekeying is not sufficient — for example, if a lock is damaged, worn beyond reliable function, or you want to upgrade your security grade — we carry replacement cylinders and full lock sets on our service vehicles. A full lock change on an apartment door typically involves removing the existing hardware, preparing the door if needed, and installing the new unit to a damage-free standard. We'll walk you through your options before any work begins, explaining which approach best matches your door, your lease terms, and your security goals.
Emergency Locksmith Response: Lost Keys, Lockouts & Same-Day Rekeying
Losing your keys in New York isn't just inconvenient — it's a genuine security event. If your keys went missing on the subway, at a bar in the East Village, or during a move, there is a real possibility that someone now has your address (from an ID or mail in your bag) and a working key to your door. That's the scenario where our 24/7 emergency locksmith service becomes critical. We answer every call around the clock, dispatch a trained technician to your location, and can rekey or change your lock the same day — often within the hour depending on your location and the time of call.
Our emergency locksmith response also covers straightforward lockouts. If you've been locked out of your apartment, our approach starts with verifying ownership or tenancy — we may ask for a photo ID, lease agreement, or other proof before proceeding. We never use force unnecessarily; wherever possible, our technicians use non-destructive entry methods to get you back inside without damaging the lock or door frame. Once you're in, we can immediately assess whether rekeying is advisable given the circumstances. Call (646) 713-0967 any time — our dispatch team answers 24 hours a day, 7 days a week.
How Much Does an NYC Locksmith Cost? Understanding Your Quote
One of the most common questions we receive — 'How much does a local locksmith charge?' or 'How much should an emergency locksmith cost?' — doesn't have a one-size answer, and any company that quotes a flat price before seeing your lock is likely to revise it at the door. At 11th Ave Locksmith NYC, we build your quote transparently based on the actual factors involved: the type and brand of lock (a standard door knob lock cylinder is a different job than a Medeco-grade mortise lock), the time of day (overnight and holiday dispatches reflect the real cost of 24/7 staffing), travel distance to your location within the New York metro area, and any parts or replacement hardware needed. What we commit to is this — before any technician touches your door, you receive a confirmed, exact price. There are no surprise add-ons once the work starts.
When people ask 'What is the average call-out fee for a locksmith?' or 'How much does an emergency locksmith cost near me?' the honest answer in New York City is that fees vary widely by provider and circumstance. We encourage you to ask us directly when you call. Our team will gather the details of your situation and give you a real number — not a bait-and-switch estimate. Transparency at the quote stage is part of how we've built trust with New York tenants, co-op owners, and building managers across the city.
Does NY Require a Locksmith License? What to Know Before You Hire
This is a question worth asking: 'Does NY require a locksmith license?' New York City does have local licensing requirements for locksmiths operating within the five boroughs, administered through the city's consumer affairs framework. What this means practically is that you should always ask any locksmith you call whether they operate in compliance with local requirements and carry insurance. At 11th Ave Locksmith NYC, our technicians are trained, experienced, and our business is insured — meaning if something goes wrong during a service call, you are protected. We operate as a legitimate, established mobile locksmith business serving the New York area, not a transient operation.
Beyond compliance, look for real indicators of quality: Does the company answer its own phone line 24/7? Can they explain the rekeying process clearly? Do they quote a firm price before starting work? Do they carry the hardware for your specific lock type on their vehicle? These are the practical questions that separate skilled, professional locksmiths from those who will leave you with a bigger problem than you started with. Our team of qualified technicians brings the experience and equipment to handle apartment rekeying and lock changes correctly the first time.
Frequently asked questions
What is the difference between rekeying and changing a lock, and which do I need?
Rekeying means the locksmith disassembles your existing cylinder and replaces the internal pin tumblers so that a new key operates the lock — all old keys stop working permanently. Changing a lock means replacing the physical hardware entirely, either just the cylinder or the full lock body. Rekeying is appropriate when your hardware is in good working condition and you simply need to revoke old key access. A full lock change makes sense when the hardware is worn, damaged, or you want to upgrade to a higher-security grade such as a Medeco or Schlage B-series deadbolt. Our technicians will assess your door and recommend the most appropriate option before any work begins.
Can you rekey a mortise lock, or does it need to be replaced?
Yes — rekeying a mortise lock is a routine service our technicians perform regularly across New York City apartments. The mortise lock cylinder is removable, and once out, it can be re-pinned to a new key configuration in the field. The condition of the cylinder matters: if the cylinder is heavily worn, corroded, or a non-standard size, replacement may be recommended. But in the majority of cases, a quality mortise lock in functional condition can be rekeyed successfully, saving you the cost and time of a full lock replacement.
My landlord says rekeying the lock will void my lease. What should I do?
This is a common concern in NYC rentals. First, review your specific lease language — many leases require tenant notification or landlord permission before changing locks, but they cannot legally prevent you from taking reasonable security steps in most circumstances. A common solution is to rekey the lock and provide your landlord with a copy of the new key, satisfying both your security needs and the lease terms. We can cut additional key copies on-site immediately after rekeying. If you have specific lease concerns, consulting a tenant's rights organization in New York is a good next step alongside calling us.
How quickly can you arrive for an emergency lock change or rekeying in New York City?
Our dispatch team is staffed 24 hours a day, 7 days a week — call (646) 713-0967 and a real person will answer. Arrival times vary based on your specific location within the New York area and current technician availability, but we prioritize emergency calls and aim to arrive as quickly as road conditions allow. Because we are a fully mobile operation, our technicians travel to you with the tools and hardware already on the vehicle, meaning service typically begins immediately upon arrival without a supply run.
Will the technician damage my door or frame during a lock change?
Our trained technicians work damage-free wherever possible, using proper tools and technique rather than brute force. Most rekeying jobs leave no mark on the door whatsoever, since the process is entirely internal to the cylinder. For full lock changes, the goal is always to work within the existing door preparation — the cutouts and bore holes already in your door — to avoid additional drilling or routing unless absolutely necessary for the new hardware. If your job requires any modification to the door, our technician will explain that clearly before proceeding.
Can you make new keys on-site after rekeying, and how many can I get?
Yes. Our technicians carry key-cutting equipment and key blanks on their service vehicles for most common residential lock types, including standard cylinder keys and many high-security key profiles. After rekeying, we can cut as many copies as you need on-site — useful if you have multiple roommates or family members who need access. The number of key copies needed and the key type are factors that will be reflected in your up-front quote, so there are no surprises when you see the final price.
