Master Key Systems

In many cases, yes — existing locks can be rekeyed and re-pinned to fit into a new key hierarchy, provided the cylinders are in good working condition and compatible with master keying. If your current locks are worn, low-grade, or not master-key-capable, our technicians will let you know exactly which ones need replacement and why. We assess hardware on-site before making any recommendations, and we confirm the full scope and price before starting work.

Most commercial properties use two to four levels: a change key level, a master key level, and possibly a grand master or great grand master above that. Technically, a system can be engineered with more layers, but each additional tier increases pinning complexity and the risk of 'ghost keys' — unintended key combinations that could open locks they shouldn't. Our experienced technicians help you find the right number of levels for your actual operational needs rather than over-engineering a system that becomes difficult to manage.

This depends on the key control system in place. With a restricted keyway system — one that uses patented key blanks that cannot be duplicated at a standard hardware store — losing a key to a departing employee is much less of a crisis. You know the key cannot be copied without authorization. If the key cannot be recovered, we can rekey only the specific cylinders that key accessed, rather than overhauling your entire system. We help you document your key schedule so that responses to lost or unrecovered keys are targeted and cost-effective.

They are related but different. In a keyed-alike setup, multiple locks share one identical key — there is no hierarchy, just uniformity. In a master key system, each lock still has its own unique change key, but additional master keys are engineered to open defined groups of locks. Many properties benefit from combining both concepts: keyed-alike locks in low-security common areas, with a master key hierarchy layered on top for staff access management. Our locksmith team will help you figure out which structure, or which combination, fits your property.

Absolutely. We are a fully mobile locksmith service covering the entire Bronx. Whether your property is in Pelham Bay, Highbridge, Co-op City, Morrisania, or Belmont, we dispatch a technician to your location. Travel distance is one of the factors reflected in your quote, which we confirm with you before any work begins. Because we operate around the clock, we can accommodate installations and consultations that fit your building's schedule, including after-hours work when tenant disruption needs to be minimized.

The timeline depends on the number of locks, the complexity of the key hierarchy, and whether hardware needs to be replaced or can be rekeyed in place. A straightforward keyed-alike job for a small office or retail space can often be completed in a single visit. A multi-floor commercial building with a full grand master hierarchy may require a scheduled installation across one or two visits to ensure every cylinder is pinned correctly and the entire key schedule is verified before we consider the job complete. We give you a realistic timeline during the initial consultation so you can plan accordingly.
