A master key system gives every tenant a key that opens only their own door and gives you one key that opens everything, with a written record of who holds what. Priority Lock and Security designs, installs and maintains master key systems for multi-tenant buildings, office complexes and apartment communities across Tampa.
A master key system is a planned set of locks where each door has its own key and a master key opens all of them. Each tenant or department key opens only its own door. The master opens every door in the group, and larger properties add levels: a master for each floor or building and a grand master above those. The system is designed on paper first, as a keying schedule, so it has room to grow without repinning the whole building later. The records are what make it work over time, and we keep those records for the buildings we service.
Probably, if you have multiple tenants or departments, if maintenance and management carry a ring of keys, or if you need reliable entry to every space in an emergency. A building running on keyed alike locks and a drawer of spares works until the first lost key, and then every door has to be treated as exposed. A master key system turns that into a smaller job: rekey the one door, issue one key, update the record.
Start with a survey of the doors and an honest list of who holds keys today. We walk the building, record each door with its hardware and keyway, test which existing keys open what, and note anything worn or not latching. From that we lay out a keying plan: which doors group together, who needs which level of key, and whether to stay on the current keyway or move to one that is harder to copy. Then the building is rekeyed to the new plan, in stages if needed, with keys issued against a signed record. This situation is normal, especially in older multi-tenant buildings in Ybor City and downtown Tampa that have passed through several owners and managers. It is fixable, and once fixed it stays fixed if the records are kept.
Treat every lock under that master as exposed and plan a rekey of the system. A lost master is different from a lost suite key, because it opens every door in its group. The work can be staged: exterior doors and sensitive rooms first, then the rest, so the building keeps operating while the change is made. Tenant keys change too, because each lock is pinned to both its own key and the master, so tenants need notice and new keys.
Key control is the habit that keeps a master key system honest: every key that goes out is written down, keys come back at turnover, copies come from one place, and the records are kept current. Stamping Do Not Duplicate on a key is a request, not a control; if the blank is sold openly, anyone with a key machine can copy it. Where copies have to be impossible without you, the answer is a restricted keyway, where blanks are not sold on the open market. Ask before the next rekey; that is the cheapest time to change keyways.

A master key system with a key log: tenants get their own key, you keep one that opens everything, and every key that goes out is written down and comes back at turnover. For copies to be impossible without you, the building moves to a restricted keyway, which is easiest to do at a rekey.
Often, yes. If the existing locks share a keyway, or can be fitted with cylinders that do, they are repinned to the new keying schedule without changing the hardware on the doors. Worn locks are replaced in the same pass.
The suite is rekeyed to a new change key and stays on the master, new keys are issued in a counted set, and the record is updated. If the tenant's own locksmith rekeys it instead, the suite usually drops off the master and nobody finds out until somebody needs to get in.
A restricted key is a key that cannot be copied at a hardware store, a kiosk or another locksmith shop, because the blanks are not sold on the open market and copies are cut only for people the owner has authorized in writing. It is the practical foundation of key control for multi-tenant and commercial buildings, and it can be built into a master key system.
