Locksmith for Landlords in NYC Who Manage Their Own Rentals

Owning a rental in NYC often means being the super, the leasing office, and the late-night contact all at once. A tenant loses a key at midnight, a unit sits between leases with old copies still out there, or a storefront tenant can’t open the gate, and every call comes to you. Alto Locksmith & Security gives rental property owners one licensed team for lockouts, tenant lock changes, and repairs, and a technician is typically on site within 20 to 30 minutes.

Alto Locksmith & Security

Landlord Locksmith NYC Services That Keep Units Rent-Ready

Small landlords rarely have a super on call or a maintenance team to send. When a lock fails in a two-family house or a six-unit walk-up, the owner handles the tenant, the repair, and the follow-up alone. A late fix can push back a move-in, strain a good tenant relationship, or leave a vacant unit open to anyone holding an old key. Our landlord lock service in NYC puts one licensed team behind all of it, for residential units and ground-floor commercial space alike.
We work as a locksmith for landlords in NYC across the buildings individual owners tend to hold, including brownstones, multi-family houses, walk-ups, and mixed-use properties with a store below. Each quote comes in writing before work starts, and we check who owns or manages the property before any lock is changed. That check protects both the owner and the tenant.

Same-Day Rekeys: Units are turned over on move-out day with keys only the next tenant will hold

Non-Destructive Entry: Lockouts are opened without drilling whenever possible, which saves you the cost of new hardware

Tenant ID Checks: Tenants show a lease, photo ID, or proof of residency before we open a unit you own

No After-Hours Surcharge: A midnight tenant lockout is quoted at the same rate as a daytime call

We Service the Brands Already on Your Rental Doors

Alto Locksmith & Security

Our Locksmith Services for NYC Landlords

Each service below is offered to individual owners and landlords, with the same licensed in-house technicians on every call

Lock Rekeying

Move-out day ends with keys returned, but nobody can say how many copies the last tenant made. We rekey the rental unit after move-out, usually the same day, and cut a fresh set before the new lease starts. Rekeying locks for a new tenant costs less than replacing hardware and gives them keys no one else holds.

Lock Replacement

A deadbolt that sticks, a knob that wobbles, or a lock damaged during a move is worth replacing before the next showing. Our landlord lock replacement service swaps worn hardware for matched locks on unit, entry, and basement doors, keyed to one plan when you prefer. A full lock change between tenants also makes sense when a former tenant left on bad terms.

House Lockout

Tenants in rented houses often have no doorman, no super, and no neighbor holding a spare key. Our House Lockout service opens front, side, and back doors without damage, and the tenant shows ID or proof of residency before we begin. The owner avoids a late-night drive to the property, and the lock stays in working order

Apartment Lockout

Late-night lockout calls reach small landlords directly, since there’s rarely anyone else for the tenant to call. Our team answers Apartment Lockout calls for your units at any hour and gets the tenant back inside once their residency is confirmed. When the lost key had the unit number on it, rekeying that same night is the safer choice.

Business Lockout

Mixed-use owners with a shop on the ground floor get a different kind of call, usually early in the morning. We open storefront doors and roll-down gate locks for your commercial tenant, and a missing key means a new cylinder before we leave. The store opens on time, and the owner keeps a good commercial tenant happy.

Emergency Lock Repair

A front door that won’t lock on a Friday night can’t wait until the handyman is free on Monday. Emergency Lock Repair from Alto Locksmith & Security covers jammed deadbolts, loose strikes, and failing cylinders at any hour. Most fixes are made on the spot, and a replacement is quoted only when repair won’t hold.

Broken Key Extraction

Tenants sometimes force an old or bent key until it snaps inside the cylinder, often on the way out the door. We pull the broken piece without damaging the lock and cut a new key on site, which saves the cost of a full lock change. A worn cylinder behind the break can be replaced during the same visit.

Lock Installation

Owners adding a second deadbolt, hanging a new door, or upgrading a rental before listing need the lock installed the first time correctly. Our experts install deadbolts, knob and lever sets, and mortise locks, and we cut new prep where the door has none. Tenants move into a unit that locks properly from day one, which saves the owner a repeat visit.

Master Key System

Owners with several units or more than one building end up carrying a ring that grows with every lease. A master key system lets you open every unit and common door with one key while each tenant’s key opens only their own apartment. We design the system around your properties and can add a grand master when you own more than one building.

Keyless Entry Systems

Every lease in a walk-up means another round of street door keys, and the old ones stay out in the neighborhood. Cleaners and delivery drivers need their own way in too. Alto Locksmith & Security installs Keyless Entry Systems on street doors and apartment doors, with codes the owner can change the day a tenant moves out. Nobody needs a copy of the building key again.

Smart Lock Installation

Owners who live outside the city or across the borough can’t always meet a tenant, cleaner, or contractor at the door. We install Schlage, Yale, and August smart locks that let you send a temporary code from your phone and see when the door was used. Each install keeps a physical key override for the day the battery or Wi-Fi gives out.

Access Control Systems

Owners of larger walk-ups and small elevator buildings often outgrow a single front door key. We install fob and card access at the entrance and shared rooms, with an entry log that shows who came in and when. Removing a former tenant’s access takes a few clicks, and no one has to collect a key.

Intercom and Buzzer Systems

A broken buzzer in a small building usually means the owner hears about it from every tenant at once. Alto Locksmith & Security repairs and replaces intercom and buzzer systems in walk-ups and multi-family houses, down to the electric strike at the front door. Tenants get their guests and deliveries in without coming downstairs.

High Security Locks

A standard key left with a broker, a contractor, or a past tenant can be copied without the owner ever knowing. Restricted-key locks from Medeco, Mul-T-Lock, and Abloy put the owner in charge of every copy, since duplicates need your sign-off. We recommend them for ground-floor units, basement doors, and any door facing the street.

Mailbox Lockout

Tenants who move out often forget to return the mailbox key, and the new tenant can’t get their mail. We open the box, replace the mailbox lock, and hand over new keys for the incoming tenant during the same turnover visit. It’s a small job that saves the owner repeated calls from a frustrated tenant.

Tenant locked out at 1 a.m. with the owner an hour away

Former tenant still holding keys after the lease ended

Front door of a two-family house that stopped latching

Key snapped in a unit lock on move-in day

2.3 Million NYC Rentals Mean a Lot of Old Keys Still in Circulation

A returned key doesn’t tell an owner how many copies were made during the lease.
Once a tenant moves out, those extra copies can still work. Rekeying between tenants changes the lock so old keys no longer work, giving owners a simple way to reset access before the next lease begins. Schedule it when the unit is empty, and the new tenant gets a fresh set of working keys.

FAQs

Frequently Asked Questions

Most turnovers only need a rekey, since the existing lock stays on the door and only the key changes. A full lock change between tenants is worth it when the hardware sticks, shows damage, or when you want a higher-security upgrade before the next lease. Our technician checks each door and gives you both prices, which leaves the choice with you.

Usually the same day, and often within hours of the call. Rekeying takes only a few minutes per cylinder, and fresh keys are cut on site. Booking it for the day the unit is empty keeps the schedule clear for painters, cleaners, and the new tenant’s move-in.

Yes, rekeying swaps the pins inside the current lock, which leaves the hardware, finish, and door untouched. It works on most standard deadbolts and knob locks, and we can rekey a lock even when no working key is left. The new tenant gets keys that the last tenant’s copies no longer match.

Tenants can usually add their own lock, though the lease or building rules may require them to give the owner a working key. If a tenant asks you for a lock upgrade, we can install it and cut a copy for your records during the same visit.

Yes, we open doors for tenants in houses, walk-ups, and small buildings at any hour. The tenant shows a photo ID or proof of residency before we begin, and most doors open by picking or decoding, which keeps your lock in working order. Tenants can call us directly, which saves you the late-night trip.

Yes, we handle Business Lockout calls, storefront door locks, and roll-down gate locks for commercial tenants in mixed-use buildings. That gives you one locksmith for the apartments above and the store below. Pricing for commercial work is also confirmed before any work starts.

Yes, a master key system can give you one key for every unit and common door while each tenant’s key opens only their own unit. It works for a single walk-up or several buildings, with a grand master key if you own more than one property. Existing cylinders can often be rekeyed into the system instead of replaced.

They can be, especially for owners who don’t live near the property. Codes can be changed between tenants without a rekey, and many models keep a log of when the door was used. Retrofit smart locks mount on the inside of the existing deadbolt, and every install we do keeps a physical key backup.
