Master Key & Rekey Systems

Running a business on Staten Island — whether a medical office near Richmond University Medical Center, a retail strip along Hylan Boulevard, or a multi-tenant warehouse off Richmond Terrace — means managing who gets in, where they can go, and when. A professionally designed master key and rekey system gives you that control without handing out dozens of individual keys or relying on outdated hardware that no longer reflects your current staff. Frank Locksmith engineers restricted key systems from the ground up, matched to your floor plan, your access tiers, and the mortise lock hardware already on your doors or the new commercial-grade cylinders we supply and install.

How Master Key & Rekey Systems Work for Commercial Properties

A master key system is a mathematically engineered lock hierarchy. Each lock cylinder is pinned so that a tenant or employee key opens only the doors assigned to that individual, while a supervisor key opens a defined subset, and a grand master key opens every door in the building. The engineering lives inside the cylinder — specifically in the pin stack heights — which is why the mortise lock is the workhorse of serious commercial key systems. A quality mortise lock body, common in Staten Island office buildings and mixed-use storefronts, houses a full-size cylinder with enough pin chambers to support the bitting depth a proper master key hierarchy demands. Door knob lock hardware, common on interior offices, can also be incorporated into the same system using matched keyways, giving you a seamless single-key experience across lock types.

Rekeying is the companion service: changing a cylinder's internal pins so that old keys no longer work, without replacing the entire lockset. Every time an employee leaves, a key is reported lost, or a tenant turns over, rekeying the affected cylinders keeps the rest of your key system intact. Our technicians carry a full range of pinning kits and cylinder tools on every mobile service call, so rekeying can happen the same day you call — including nights and weekends. Staten Island businesses do not have to wait until Monday morning or until a shop has a slot open. We come to you.

Restricted Key Systems: Why Duplication Control Matters

An unrestricted key can be copied at any hardware store on Forest Avenue or Victory Boulevard in minutes. A restricted key system uses a proprietary keyway — a key blank that is not available to the general public and can only be duplicated through an authorized source. When Frank Locksmith installs a restricted master key system, every key cut is logged, and additional copies require documented authorization. This is the standard that hospitals, legal offices, property management companies, and schools operate under, and it is increasingly what insurance carriers and building managers expect from commercial tenants across the five boroughs.

Restricted systems also protect the integrity of the key hierarchy itself. In an open keyway system, a determined person could purchase a blank, make modifications, and attempt unauthorized duplication. With a restricted keyway, the geometry of the blank itself is the first line of defense, independent of the mechanical lock pins. Pair that with a high-security mortise lock cylinder featuring anti-pick, anti-drill, and anti-bump features, and you have a layered access control solution that covers the most common methods of unauthorized entry — without requiring electronic credentials or a subscription to a cloud platform.

What Our Commercial Locksmith Process Looks Like On-Site

Every project starts with a site assessment. One of our skilled technicians walks the property with you, identifies every door that needs to be on the system, notes the existing hardware — mortise lock bodies, door knob lock sets, panic bars, deadbolts — and maps out the access tiers you need. Who should open every door? Who should be limited to a single office or corridor? Are there time-sensitive spaces like server rooms, pharmacies, or cash offices that need a separate sub-master? These answers shape the pinning chart before a single cylinder is touched.

Once the hierarchy is designed and you have approved the plan and the confirmed price, our technicians repin or replace cylinders on-site, cut keys to the exact bitting specifications of the chart, test every key-and-lock combination in the system, and provide you with a documented key record. We handle mortise lock cylinders, rim cylinders, interchangeable core systems, and standard keyway cylinders. If existing hardware is worn, misaligned, or incompatible with a proper master system, we will tell you before we start — not after — and walk you through replacement options that fit the door prep you already have. Call (347) 284-0806 any time to schedule your site visit.

Frequently asked questions

Answers to what our customers ask most. Still unsure? Just call.

What proof do you need for a locksmith to rekey a commercial property?+

Ownership or authorized occupancy verification is required before any work begins — this is a non-negotiable part of responsible locksmith practice. For a business owner, that typically means a government-issued ID that matches the business registration, a lease agreement, or a deed. Property managers working on behalf of a building owner should have a management agreement or written authorization letter. Our technicians are trained to verify authorization professionally and without confrontation. If you are a tenant rekeying your own leased space, a copy of your lease showing the unit address is usually sufficient. We complete this step before any tool touches a lock.

What are common reasons to call a locksmith for a commercial property?+

The most frequent commercial calls we receive on Staten Island involve employee terminations or resignations where an immediate rekey is needed to prevent unauthorized re-entry, tenant turnover in multi-unit buildings, lost or unreturned master keys that compromise the whole key hierarchy, broken or worn mortise lock cylinders that no longer operate smoothly, and commercial lockouts during off-hours when the only keyholder is unavailable. We also handle new business move-ins where the previous tenant's keys are unknown quantities — rekeying the moment you take possession is the simplest way to start fresh. Because we operate 24/7, none of these situations require you to wait until a business day.

How much should a locksmith cost, and what factors shape the price for a master key system?+

There are no flat rates for master key and rekey systems because the scope varies significantly from property to property. The factors that determine your final quote include the number of locks in the system, the type of hardware involved (mortise lock cylinders, door knob lock sets, high-security cylinders, interchangeable cores), the complexity of the key hierarchy you need, whether existing cylinders can be repinned or need to be replaced, the time of day the work is scheduled, and the travel distance to your location from our current position. We confirm an exact, itemized price with you before any work begins — there are no surprises on the invoice. Call (347) 284-0806 to describe your property and get a clear quote.

What is a locksmith call-out fee, and does Frank Locksmith charge one?+

A call-out fee — sometimes called a service fee or dispatch fee — is a charge some locksmiths apply just to arrive at your location, separate from the cost of any work performed. Our pricing structure is transparent: when you call us, we gather the details of your job and give you a complete up-front price that accounts for travel, labor, and parts. We do not believe in quoting a low number to get in the door and then adding fees on arrival. The price we confirm before dispatching is the price you pay, whether the call is at noon on a Tuesday or 2 a.m. on a Saturday.

I searched online and got blocked from a directory site — how do I find a trustworthy local locksmith?+

It is genuinely frustrating when automated security systems on listing directories flag your connection and display messages like 'You are unable to access this page,' 'Why have I been blocked?', or 'What can I do to resolve this?' — especially during an emergency. Those blocks are triggered by network-level filters, VPNs, or high-traffic IP addresses and have nothing to do with your eligibility to use the site. The simplest workaround is to skip the directory entirely and call a local locksmith directly. For Staten Island, that number is (347) 284-0806. We answer 24/7, so you reach a real person immediately rather than waiting for a web page to load or a form submission to be answered.

Why can't I just reset a password or update a digital access system instead of rekeying physical locks?+

Digital access systems — keypads, fobs, smartphone-based entry — do have the advantage of a password or credential reset that does not require a physical service call. However, most Staten Island commercial properties still rely on mechanical locks as the primary or backup layer, and a digital reset does nothing for a physical cylinder that an old key can still operate. Many businesses run hybrid systems: a keypad on the main entrance and a mortise lock or door knob lock on interior offices. In those cases, rekeying the mechanical cylinders is the necessary complement to any credential reset you perform in software. Our technicians can work alongside whatever electronic system you have, ensuring the physical and digital layers are synchronized rather than leaving a gap in either one.

Locked out or need a lock fixed? We are on the way.
