Loft tenants, South Williamsburg families, venue managers and walk-up residents ask us different things, so the answers below are sorted by door. Anything that applies citywide is answered once on the NYC smart lock hub, and stoop-and-vestibule matters for rowhouses are on the Brooklyn smart lock page, so they are not repeated here.
Lofts and Loft Law buildings
Our loft door still carries the surface bolt and padlock hasp from its factory days — do those come off when a smart lock goes on?
Usually yes, and they should come off before anything electronic goes on. A hasp and padlock on the outside of a dwelling door is a warehouse habit, not an apartment lock: it can be cut in seconds, it shows the whole street when you are away, and a padlock on the inside of an occupied apartment can delay someone leaving in an emergency. Surface slide bolts are the same story — useful on a freight door that is locked from the inside at night, a problem on a door people live behind. We take them off, fill and patch the bolt holes in the steel or timber, and then look at the door with fresh eyes: thickness, whether it has ever been bored for a cylinder, how much it sags, and whether the frame is solid where a strike will go. On many loft doors the answer is a heavy-duty smart deadbolt in a new bore with a reinforced strike plate screwed deep into the frame; on very thick or hollow-metal doors it may be a surface-mounted or wired lock instead. If the hardware is original and you want to keep it for its look, it can stay on the door as decoration, but it should be disabled so it can never be used.
Our building is partway through Loft Board legalisation — should a smart lock wait until the fire-safety work reaches our unit?
It depends on what the owner's legalisation plans say about your door. The Loft Law requires interim multiple dwellings to be brought up to residential fire and safety standards in stages, and the work often includes unit entrance doors, frames and stair doors. If your door or frame is due to be replaced, a lock fitted now may have to come off again, and drilling a door that is about to be swapped is money wasted. Ask the owner or the tenants' association for the scope of the next phase; if the unit door is in it, we can fit a retrofit unit that mounts on your existing deadbolt and moves to the new door later, or wait. If the door is staying, there is no reason to wait. Either way we do not alter fire-rated doors or labelled frames in ways that would undo the legalisation work, and we tell you in writing what we did to the door so you can show it to the owner's architect. This page is not legal advice about the Loft Law; your tenants' association or a housing lawyer is the right source on that.
The Loft Board's fire rule keeps lithium battery chargers away from an IMD unit's front door — does that limit where a smart lock or its charger can go?
Not the lock itself, but it is worth knowing about. The Loft Board's fire-egress rule for interim multiple dwellings says lithium battery charging devices may not be stored in or near the front door of an IMD unit — a rule aimed squarely at e-bike and scooter batteries, which have caused serious fires in New York. A typical smart deadbolt runs on ordinary AA cells inside the lock and is not a charging device. Where the rule matters is the gear around the lock: a rechargeable lock battery pack being topped up on a shelf by the door, a docking station for a video doorbell, or the habit of parking an e-bike on charge in the entry because that is where the outlet is. We place hubs and bridges away from the door where we can, we recommend charging any rechargeable lock pack somewhere else in the unit, and if the only outlet near the entry is the one the e-bike has been using, we will say so. The point of the rule is to keep the way out clear of the thing most likely to catch fire.
Our loft entry is an oversized, very heavy door — will a smart deadbolt cope with it?
The lock copes with the weight; the problem is what the weight does to the hinges over time. A wide, heavy door slowly drops on its hinges, and a door that has dropped even a few millimetres makes the bolt rub against the top or bottom of the strike. A manual deadbolt hides that because people push or lift the door while turning the key. A motorised smart deadbolt cannot, so it strains, drains its batteries, reports a jam, or stops halfway. Before we fit anything to a big loft door we check the hinges and the gap at the top of the frame. If the door has dropped we tighten or replace the hinges, add a fourth hinge or a heavier-duty one where the frame allows, and only then set the strike so the bolt slides in without touching. Smart locks are also rated for door thickness — common models list 1-3/8 to 1-3/4 or 2 inches, a few up to 2-1/4 — and a heavy timber loft door can be thicker than that, in which case the plan changes to a lock designed for the thickness rather than one forced onto it.
Our loft's back door opens onto the old freight stair — can it be locked from the stair side and still let us out in one motion?
Yes, and that is exactly how it must be set up. The Loft Board rule says the door to an indoor stair has to be self-closing, and city fire-safety guidance is clear that an apartment door must open from the inside without a key — double-cylinder deadbolts, which need a key on both sides, are illegal on apartment doors. So a keypad or smart deadbolt can secure the stair door from the outside, but on the inside you need a thumb-turn or lever that opens it in one simple movement, with no code, no phone and no key. We also look at whether that door is a second exit for the unit: if it is, it cannot be chained, barred or blocked with furniture, and the lock we fit cannot have an "inside lockout" mode. Where the stair door has a closer, we check that the closer and the new bolt work together so the door latches every time it swings shut behind you.
South Williamsburg households and Shabbat
Our landlord wants to make the building door fob-only, and several families here keep Shabbat — has that been fought over before?
It has, in Queens. In 2015 Orthodox Jewish residents of LeFrak City, a complex of rental high-rises in Corona, sued the management company in federal court after lobby doors were changed to open with an electronic key, saying that using it on Shabbat would break their religious law and left them waiting outside for someone to let them in. They asked for one door per building with an ordinary lock. We do not know how that case ended and it is not a ruling on your building, but it shows the problem clearly. For an owner in South Williamsburg the practical answer is to keep one entrance with a mechanical key or a mechanical push-button lock alongside the fob or keypad, so nobody's access depends on electronics. We can fit an electronic reader and strike that leaves the mechanical cylinder fully working, so residents who keep Shabbat use a key or a push-button code and everyone else uses the fob. If you are a tenant facing this change, raise it with the owner in writing; whether the fair-housing rules require it in your case is a question for a lawyer, not for us.
Can a mechanical push-button lock we use on Shabbat count as the extra lock a tenant is allowed to add?
Possibly, but read the law before you rely on it. Section 51-c of the Multiple Dwelling Law lets a tenant in most multiple dwellings install a lock of their own in addition to the owner's, as long as it is no more than three inches in circumference, and requires the tenant to give the landlord a duplicate key on request. A mechanical push-button deadlock fits the spirit of that well — it needs no power, keeps no log and works the same on Saturday as on Tuesday — but it has no key to hand over, so most tenants give the landlord the code in writing or choose a push-button model with a key override. The law does not cover buildings run by a public housing authority, hotels or dormitories. We fit push-button locks as well as electronic ones, check that the inside opens without a code, and leave you the paperwork describing what was installed. Whether a particular model meets 51-c in your lease is a question for a housing lawyer; whether it is right for Shabbat is a question for your rabbi.
Shops, venues and short leases
We run a music venue — can a touring crew get in for load-in without a staff member standing at the stage door?
Yes, with a credential that only works during the load-in window and only on the doors the crew needs. A wired keypad or reader on the stage or loading door, controlled from the venue's own system, can issue a code that becomes valid at, say, two in the afternoon, stops working once doors open to the public, and only releases the loading door — not the office, the bar store or the box office. Every use is logged, so if gear goes missing you know when the door opened. The production manager can create or cancel those codes from a phone. What we do not do is set the loading door to stand open by itself for hours: a door left on a schedule to stay unlocked becomes a public entrance, and venues are exactly where uninvited people try the side door. During the show the same door must open from inside instantly for anyone leaving, so it keeps its push bar and its exit signage, and the lock never interferes with either. If the venue has a fire alarm, our Williamsburg fire alarm team can check how the door hardware and the alarm interact.
Our pop-up on Bedford is only leased for three months — is keyless entry worth it, and what happens when we leave?
For a short lease the answer is usually a lock that fits the existing preparation and comes off cleanly. Cutting an electric strike into an aluminium shopfront frame makes sense for a long tenant and very little sense for a summer pop-up. Instead we look at what the door already has — often a mortise cylinder or an existing deadbolt bore — and fit a keypad or smart lock that uses those holes, so staff get individual codes and you can see who opened up in the morning. When the lease ends we take it off and reinstall the landlord's original cylinder or lock, which we keep labelled for you. Agree this with the landlord before we start, because some leases say any change to the doors belongs to the building at the end. If you are likely to renew, tell us; it may be cheaper to do the job properly once than to fit a temporary lock now and a permanent one later.
Tenement walk-ups
Our smart lock keeps telling us the door is open when it is shut, and our walk-up shakes whenever trucks pass on Broadway — are the two connected?
Very possibly, if the door rattles in its frame. Many smart deadbolts use a small magnetic sensor to know whether the door is shut before they auto-lock, and a door that moves in a loose frame can make the sensor read "open" for a moment and the lock refuse to throw, or report the door ajar at three in the morning. The fix is not in the lock: it is a door that sits firmly closed. We adjust the strike so the latch holds the door snug against its stop, add weatherstrip that cushions the door rather than letting it chatter, and set the sensor magnet where the gap is most stable. We also use thread-locking compound on the lock's mounting screws on doors that get a lot of vibration, so they do not walk loose over months. If the lock still reports false openings after that, most apps let the sensor be switched off and auto-lock run on a timer instead, which is a reasonable trade on a street-facing door in an old building.
