Lock Change and Rekey Service in Midtown Manhattan and All Five Boroughs of NYC

If you've lost keys, changed tenants, had an employee leave, or just moved into a new space, a lock change or rekey is the fastest way to restore full control over who can enter your property. Imperial Locksmith & Security handles both services for commercial buildings, multifamily properties, offices, and residences across Midtown Manhattan, the Financial District, Chelsea, Tribeca, the Upper East Side, Murray Hill, and every other neighborhood in all five boroughs of New York City.

What is the difference between a lock change and a rekey, and which one does your NYC property actually need?

A rekey means a technician disassembles the existing cylinder, replaces the internal pins or wafers, and cuts a new key to match the new configuration. The lock hardware stays in place. This works well when the hardware is in good condition and you simply need to invalidate old keys.

A lock change means replacing the entire lock unit. This is the right call when:

• The existing hardware is worn, damaged, or code-noncompliant
• You are upgrading to a higher-security or smart lock cylinder
• The building is switching to a new key system or access control platform
• The current lock brand cannot be rekeyed to your master key system

For most commercial clients in Midtown Manhattan, the answer is a rekey first, with targeted hardware upgrades where the cylinders are undersized or worn. For residential renters in neighborhoods like Chelsea or Murray Hill, a rekey is usually all that is needed between tenants.

Which lock brands and cylinder types does Imperial Locksmith & Security work with in New York City?

NYC buildings run a wide range of hardware. Imperial Locksmith & Security rekeyes and replaces cylinders across the full spectrum of commercial and residential grade products found in the five boroughs.

High-security cylinders: Medeco Maxum, Abloy Protec2, Mul-T-Lock MT5+, ASSA Abloy High Security. These use patented keyways and pick-resistant designs. They are the right choice for server rooms, executive offices, and any space in Midtown or the Financial District where key control is non-negotiable.

Commercial-grade mortise and cylindrical locks: Schlage L-Series mortise, Sargent 8200 Series, Yale 8800 Series. These are the workhorses of office buildings and multifamily properties. We rekey them on-site and can swap cylinders to bring them into a master key hierarchy.

Residential and multifamily: Kwikset SmartKey, Schlage B-Series deadbolts, Baldwin Estate Series. SmartKey cylinders can be rekeyed in minutes with the included tool. We also install and rekey August Smart Lock Pro and Schlage Encode for property managers who want keypad entry without replacing the entire door prep.

Intercom and high-rise entry systems: Many Upper East Side and Tribeca buildings use Medeco or Best SFIC (Small Format Interchangeable Core) cylinders in common-area doors. We stock cores and keys for these systems and can rekey without coordinating a separate order or waiting on a distributor.

How does the lock change and rekey process work for a commercial building or property manager in NYC?

The process moves in four steps.

1. Site assessment. A technician visits your property, audits the existing hardware, documents every opening, and identifies which cylinders can be rekeyed versus replaced. For large buildings in Midtown or multifamily properties in the outer boroughs, this step prevents surprises on the day of service.
2. Key system design. If you are rekeying into a master key system, we map the hierarchy before cutting a single key. Grand master, master, and change keys are assigned by department, floor, or tenant. We use Medeco or Mul-T-Lock restricted keyways so keys cannot be duplicated at a hardware store without authorization.
3. Service day. Technicians rekey or replace cylinders door by door. Commercial jobs are scheduled to minimize disruption during business hours. Emergency calls across all five boroughs are prioritized and dispatched the same day.
4. Key control documentation. We provide a written record of every key issued, every cylinder rekeyed, and every change key versus master. Property managers in buildings on Madison Avenue or elsewhere use this log to track key accountability going forward.

For property managers overseeing multiple buildings across boroughs, we coordinate multi-site rekeying under a single service agreement so key profiles and master key hierarchies stay consistent across your entire portfolio.

Frequently asked questions

How long does a rekey take on a commercial property?

A single cylinder rekey takes about 10 to 15 minutes per lock. A suite of 20 or more office locks can typically be completed in a few hours, depending on hardware type and access logistics.

Can you rekey a building master key system without replacing all the hardware?

Yes. As long as the existing cylinders accept a new key profile, we can rekey the entire master key system in place. If the cylinders are worn or incompatible, targeted replacements are the smarter call.

What if I lost the only key and need emergency access in NYC?

Contact Imperial Locksmith & Security through the website. We serve all five boroughs and can dispatch a technician to pick, bypass, or replace the lock so you regain access without damaging the door.
