Building Security
Amenity doors are the forgotten locks in a New York City building. The apartment doors get attention, the front entrance gets attention, and the laundry room, bike room, storage cages and package room run for years on whatever hardware the last contractor had on the truck. The right setup is simple: a commercial storeroom-function lock that is always locked from outside and always open from inside, a working closer so the door relocks itself, and access on a credential or key level you can revoke without touching anyone else's door.
Every shared room in a building is a small security problem that nobody owns. The super has a key, the porter has a key, a former handyman probably still has one, and the door itself has a knob that a resident propped with a milk crate three years ago because the closer slams. Nothing is visibly broken, so nothing gets fixed.
Then a bike disappears from the bike room, a package wall gets cleaned out, or a resident finds somebody sleeping in the laundry room at two in the morning, and the board wants to know who had access. That is usually the first time anyone counts the keys. It is the same conversation in every borough, and the honest answer is usually that nobody knows.
Not every door in the basement deserves the same hardware. These are the ones that earn real attention, roughly in the order they cause problems.
The hardware question answers itself once you decide what the door has to do: stay locked to the outside without anyone thinking about it, and never trap anyone inside.
What does not belong: a privacy knob with a push button, a hasp and padlock on a door people use daily, a deadbolt that needs a key from the inside, or a chain. Each one either fails open or traps somebody.
The real question in a shared building is not which lock is strongest. It is how fast you can take access away from one person without disturbing anyone else.
A mechanical key is cheap, works in a blackout, and never needs a controller - and it is uncontrollable the moment it is copied or not returned. A credential costs more up front and depends on power and a panel, but you can delete one resident's fob in seconds and leave the other eighty alone. That asymmetry is the whole argument, and it is why most NYC buildings run both: credentials on the doors residents use daily, mechanical keys on staff-only rooms, with a mechanical override everywhere so a dead panel never locks a building out of its own basement.
If you are already running fobs, the discipline that matters is the list - who holds what, and what happens on move-out. See what to do when a building fob is lost and how access control works on a small system.
We work on common-area and amenity doors across the five boroughs - laundry and bike rooms, storage, package rooms, compactor and stair doors - including storeroom-function hardware, closers, restricted keyways and master key systems for supers, boards and managing agents.

This is the part that gets buildings in trouble, and it is worth being plain about. A door that sits in the path people use to get out of the building has to open from the inside without a key, a tool or any special knowledge. That applies in a basement corridor just as much as it does at the front of the building.
In practice that means no double-cylinder deadbolts on a basement passage door, no padlock and hasp on anything a person might be behind, nothing chained during a shift because the porter is tired of residents wandering in. If the room needs to be closed at night, close it with hardware that locks the outside and frees the inside. The same logic governs stair and fire doors - see fire escape door lock requirements in NYC and panic bar repair and adjustment - and when a door is genuinely part of a required exit, that is an FDNY and HPD question to confirm for your specific building, not a judgment call for a board meeting.
Hardware is a one-time decision. Key control is the part that quietly decays, and it is what turns a well-secured building into an open one without anything visibly changing.
Amenity doors fail in a short and predictable list.
If that walkthrough produces more than a couple of items, start with the busiest door - usually the laundry room - because fixing its closer and latch removes the reason residents defeat it. For who should be doing the work, see how to choose a locksmith in NYC and how to verify a locksmith license. New York City licenses locksmiths; ours is NYC DCA #1362785-DCA, and any legitimate company will give you theirs without being asked twice.
A commercial storeroom-function lockset: the outside lever or knob is always locked and needs a key or credential, while the inside always opens freely. Pair it with a working door closer so the door relocks itself every time. Residential knob-and-privacy hardware is the wrong choice here because it depends on someone remembering to lock it.
A building can set amenity hours and lock the room outside them, as long as the door is not part of a required exit path and nobody can be shut inside. If the laundry room sits off a stair or basement passage that people use to get out, the door still has to release from the inside without a key. House rules on hours are a management decision; the egress side is not negotiable.
No. Keep amenity and common-area doors on their own keyway or their own level of a master key system, so a resident key opens the laundry and bike room but not the boiler room, roof or other apartments. Mixing them means every rekey anywhere forces a rekey everywhere.
For any door with turnover behind it, usually yes, because a fob can be deleted in seconds when a resident moves out while a copied key cannot. Keys still make sense on low-traffic doors and as the mechanical backup when power or a controller fails. Many NYC buildings run both.
Almost always because the closer is too strong, the latch drags, or there is no easy way to carry a laundry basket through. Fix the mechanical reason first - adjust the closer, align the strike - because a door that is annoying to use gets defeated by residents, not burglars.
Yes, and doing them together is the point: a single visit that puts the common doors on one controlled system is far cheaper than chasing them one at a time. Tell us how many doors, what hardware is on them and whether you want keys, credentials or both. Call (718) 412-1332.
