Master Key System Setup

A tiered keying hierarchy is built on a simple principle: each key operates only the doors it is authorized to open, and higher-tier keys override lower ones in a controlled, documented way. At the base level, a change key opens a single lock — typically one apartment unit or one private office. Above that, a sub-master key opens a defined group of locks, such as all units on the second floor of an Astoria apartment building or all supply rooms within a dental practice. The grand master key, held by the building owner or head administrator, operates every lock in the entire system. Because these relationships are engineered into the keyway and pin stack of each cylinder, the access boundaries are mechanical, not just procedural — you cannot accidentally hand someone the wrong level of access.

Our technicians most often build these systems around high-security mortise lock hardware. A mortise lock is installed directly into a pocket routed into the door edge, giving it far superior strength and longevity compared to a surface-mounted cylindrical lock. For commercial and multi-unit residential applications in Queens, a mortise lock is the preferred foundation because it accommodates interchangeable core cylinders, supports lever or knob trim on both sides, and resists the wear that comes from hundreds of entries per day. We carry Schlage, Medeco, and comparable commercial-grade mortise lock bodies and can match your existing trim profile or recommend an upgrade that fits your building's aesthetic and security requirements.

The physical installation of a master-keyed mortise lock requires precise routing of the door edge pocket, correct backset measurement, and careful alignment of the strike plate on the frame — mistakes at any of these stages can cause binding, premature wear, or a lock that fails to latch under load. Our skilled technicians are trained specifically in commercial door hardware and perform damage-free installations wherever the door and frame conditions permit. For older Queens brownstone doors with non-standard thicknesses or steel-clad fire-rated doors common in Jamaica and South Jamaica apartment corridors, we bring the appropriate tooling and hardware to handle non-standard conditions without forcing components that do not fit.

Once the mortise lock body is set, the keying itself is carried out using a pinning kit and a documented key schedule. We record every key number, every lock position, and every access tier in a system diagram that we hand over to you at the end of the job. This documentation is critical: when a property manager leaves, you know exactly which key to rekey rather than replacing every cylinder in the building. Selective rekeying is one of the most practical advantages of a properly designed tiered system, and it is one of the main reasons Queens commercial property owners who manage multiple doors prefer this approach over independent deadbolts on every door.

We receive a lot of questions that boil down to: how much should a locksmith cost in NYC, how much should locksmiths charge, or how much does a locksmith charge per hour? We do not publish flat figures because no two master key projects are alike — a four-door office in Woodside and a forty-door apartment building near Rockaway Beach involve completely different scopes of work. The factors that shape your final quote include the number of doors and cylinders being keyed, the grade and brand of mortise lock hardware required, whether existing doors need prep work or frame reinforcement, the time of day the work is scheduled, and travel distance within Queens.

You may also hear terms like call-out fee when researching locksmith pricing. A call-out fee is a base charge some locksmiths apply simply for arriving at your location, separate from labor and parts. At Roy Locksmiths, we believe you deserve to know exactly what you are paying before we begin, which is why we walk you through every line of your quote over the phone or on-site before any work starts. There are no surprises added to the invoice after the job is done. If your situation changes mid-project — for example, you discover additional doors that need to be incorporated into the hierarchy — we pause, update the quote, and get your approval first.
