Locksmith Services for Property Management Companies in NYC
Most door calls to a management office come down to the same few problems. A resident is locked out late at night, the front entrance stops latching on a Sunday evening, or a commercial tenant can’t open the gate before business hours. Each one turns into a complaint, a work order, and time your team doesn’t have. Your office needs one number for all of it, and Alto Locksmith & Security works as a 24/7 locksmith for property management in NYC across apartment units, office suites, and storefronts.
As a commercial property locksmith in NYC with 10+ years of hands-on experience on the team, we know pre-war apartment doors as well as modern access control. Mobile technicians carry the hardware for most building jobs, which keeps return visits to a minimum. We coordinate with your super and agree on the price in writing before any work begins, on residential units and commercial space alike.

Lock Brands You Already Trust Are the Ones We Install
Commercial Property Locksmith NYC Services for Every Door You Manage
Unit Doors & Common Areas Covered by Licensed Technicians
Apartment Lockout
When a tenant loses their key after hours, the call often lands on the management company’s emergency line. We handle that call directly, confirm the tenant’s residency, and open the unit without damaging the door or the lock. If the key is gone for good, the lock is rekeyed on the spot, which keeps a lost key from becoming a security issue.
Business Lockout
A commercial tenant locked out before opening starts losing sales, and the first call often goes to the landlord. Our Business Lockout service gets the tenant inside by picking or decoding the lock, then rekeys or replaces it on the spot if the keys are gone. Commercial tenants usually reopen within the hour, and the storefront door stays undamaged.
Lock Rekeying
Keys rarely all come back at move-out. Tenants hand copies to roommates, dog walkers, and contractors, and every one of them still opens the door once the lease ends. Our bulk rekey service for property managers in NYC resets a single unit or an entire floor the same day, with fresh keys cut before the technician leaves.
Master Key System
Every building has a super who needs most doors, staff who need some, and tenants who need only their own. Separate keys for each group turn into a heavy ring and a long list of copies to track. We design master key systems for managed buildings in NYC with individual, sub-master, and master tiers, plus a grand master key for multiple properti
Lock Installation
New units, converted storefronts, and renovated common areas often need locks where none existed before. We install deadbolts, mortise locks, and commercial lever sets from scratch, including new door prep on metal and wood doors and panic bars on commercial exits. Every lock is keyed into your existing plan, which keeps new doors from adding another loose key to track.
Lock Replacement
Lobby doors and apartment entries take constant daily use, and the hardware wears out long before the door does. Most owners first hear about a worn cylinder or a loose strike through a tenant complaint. Our team replaces worn locks with ANSI Grade 1 hardware on main entries and matching locks on unit, basement, and roof doors.
Emergency Lock Repair
Lock failures tend to happen after the super leaves for the night or over a holiday weekend. A jammed unit deadbolt, a spinning entrance cylinder, or a roll-down gate stuck halfway on ground-floor retail needs same-day attention. Most of our repairs are finished within half an hour of arrival because technicians carry parts for residential and commercial locks at all hours.
Broken Key Extraction
Worn cylinders are where keys tend to snap, and a broken key in a unit or storefront lock can hold up a move-in or an opening. We extract the fragment without damage and cut a new key before leaving the property. When the cylinder itself is worn, the technician recommends a rekey or replacement and confirms the price first.
Access Control Systems
Lobbies, mailrooms, and amenity spaces see residents, staff, and vendors all day, and a metal key never shows who used it. Each person gets a fob, card, or PIN code, every entry is logged, and a lost credential is canceled in seconds. Our team installs these systems for residential and commercial buildings and connects them to the cameras you already run.
Keyless Entry Systems
Changing a code takes a minute, while collecting and replacing keys after a move-out can take days. Keypads and fobs give each tenant or staff member their own access, and you decide when it ends. Our experts install Keyless Entry Systems on unit doors, storage rooms, and shared entrances, often working with the existing locks.
Magnetic Door Locks
Card-reader lobbies and glass office doors in mixed-use buildings rely on maglocks, and a failed power supply or loose plate leaves them unsecured. We install and service Magnetic Door Locks with fail-safe release for emergency exits, matched to each door type and building layout. Residential and commercial tenants get entrances that lock reliably and still open during an outage.
Intercom and Buzzer Systems
Tenant complaints about a buzzer that won’t ring or a lobby door that won’t release land on the management office first. Alto Locksmith & Security repairs and installs intercom and buzzer systems for residential lobbies and commercial entrances, including the electric strike or lock at the door. Fewer buzzer complaints reach your office, and visitors get screened before they enter.
High Security Locks
Standard keys can be copied at almost any hardware counter, and a building has no record of how many are out there. That risk matters most on boiler rooms, package rooms, and the management office. The Medeco, Mul-T-Lock, and Abloy cylinders we fit use restricted keys, and new copies come only from an authorized dealer with your approval.
Smart Lock Installation
Short-term rentals and furnished units change occupants often, and handing out physical keys each time adds risk and work. Our Smart Lock Installation covers Schlage, Yale, and August models with codes you can create and delete for each stay or tenant. Every install includes a mechanical key backup for the day a battery runs flat.
Mailbox Lockout
Tenants lose mailbox keys, and the request usually lands on the management office. Waiting on the carrier or a busy super can leave residents without their mail for days, and the complaints come back to you. Residents get their mail back in one visit, since our technicians open apartment and building mailboxes and cut replacement keys, usually without replacing the lock.

Frequently Asked Questions
Do you offer a lock maintenance contract for property management companies in NYC?
Yes, many managers set up standing service with us for turnover rekeys, scheduled lock checks, and emergency calls. We learn your buildings, keep track of your key plan, and book routine work around your tenants. Call us to talk through what ongoing service would look like for your portfolio.
How fast can you rekey a unit after a tenant moves out?
Same day in most cases, including bulk rekeys across a full floor. Rekeying takes a few minutes per cylinder, and we cut fresh keys on site before we leave. For units on a master key system, we key the new cylinders back into your existing plan.
Can you set up a master key system for buildings we already manage?
Yes, we walk the building, map who needs access to which doors, and build the tiers from individual keys up to a grand master for multiple properties. Most existing cylinders can be rekeyed into the new system, and restricted keyways keep new copies under your control.
Can you handle work across several buildings in different boroughs?
Yes, our technicians work in Manhattan, Brooklyn, Queens, the Bronx, and Staten Island, and one building management locksmith team can handle rekeys, repairs, and upgrades at every address in your portfolio.
Do you respond to tenant lockouts 24/7?
Yes, including nights, weekends, and holidays. Tell us the building address and unit number, and a technician is typically there in 20 to 30 minutes at the same daytime price.
Do you check ID before opening a tenant's door?
Yes, a tenant shows a photo ID or proof of residency before we open a unit. Building-wide work like rekeys and lock changes goes ahead once the owner, the manager, or the contact your office names has approved it.
