Residential Locksmith
At a New York apartment viewing you get about ten minutes, and almost all of it goes to the kitchen and the light. Spend two of those minutes on the entrance door, the building front door, and the windows. Check that the deadbolt throws fully, that the door closes and latches on its own, that there is a working peephole, and that the frame is not split around the strike. Then ask who else still holds a key.
Before you sign, a lock problem is a condition of the deal. After you sign, it is a repair request competing with every other repair request in the building. That is the whole reason to look at the hardware while the agent is still trying to rent you the apartment.
It is also the only moment you can walk away at no cost. A direct question about rekeying is useful either way: a landlord who rekeys between tenants says so immediately, and one who gets vague about it has just told you how many keys are probably out there.
More apartments fail here than at the lock. Push the door closed from a standing start, without touching the handle. It should swing shut and latch by itself. If you have to lift it, shove it, or lean on it to turn the bolt, the door is out of alignment or the hinges have sagged, and the result is a door that gets left unlocked because locking it is annoying.
Then look at the frame around the strike plate for splits, filled screw holes, or fresh paint over a repair. That pattern usually means the door has been forced, and a frame broken once is weaker than it looks. Reinforcing it is a different job from changing a lock, covered in strike plates and door frame reinforcement. Check the hinges too, since exposed pins matter on a door that swings into a public hallway, as set out in door hinge security.
Look through the peephole. A painted-over, cloudy, or missing one is both a security gap and a tell about how the unit was turned over, as is a chain guard that is bent, unscrewed, or mounted too high to use. What a tenant can reasonably ask for is in peepholes and chain door guards in NYC apartments.
A strong apartment door behind a building door that never latches is a strong apartment door in a public hallway. Check the front door the same way: does it close and lock on its own, or rest against the frame? Is the latch taped, wedged, or worn enough that a push opens it? A building entrance that stands open is the most common security problem in New York rentals, covered in what to do when a building front door lock is broken.
Test the intercom while you are there. Ask the agent to buzz you in from the apartment. If the release does not work, residents prop the door, and then nothing else about the entrance matters. The usual failures are in apartment buzzer and intercom lock problems.
Glance at the rest of the building too: whether the bank of mailboxes has been pried before, whether the package room door actually locks, and whether the basement or back yard door is secured or held with a bent hasp. Those tell you more than the lobby paint does.
If the apartment is on the ground floor, in a basement, or has a window onto a fire escape, that window is now part of your entrance plan. Check whether window locks exist and work, and whether any fire-escape window has a gate. A gate on a fire-escape window has to be an approved type that opens from the inside without a key, never a padlocked grille, which is the distinction made in window gates and fire escape requirements.
A garden or basement unit usually has a second door to a yard or areaway, and it is almost always the weakest opening in the apartment. See basement apartment door security and window lock security for NYC apartments.
New York City sets a floor for apartment door security rather than leaving it entirely to the landlord. In multiple dwellings the Housing Maintenance Code calls for an apartment entrance door with a heavy-duty latch set and a peephole, and buildings with three or more apartments are also expected to have a chain door guard on each entrance door. Separately, where a child ten or younger lives in the apartment, the owner is responsible for installing window guards.
Requirements depend on the building class and change over time, so confirm what applies with the Department of Housing Preservation and Development rather than relying on an agent. The more useful move is to look up the address in HPD's public violation records before you sign: a history of open door and lock violations tells you how repairs get handled here, which is the point of HPD violations for door locks.

Most of what you find is fixable and worth a conversation. These few are different, because each is a signal about the building rather than about one door.
Assume the apartment was not rekeyed unless you have it in writing. The previous tenant, their roommates, a dog walker, a cleaner, and whoever the super lent a key to during the turnover may all hold working copies. None is necessarily a threat, but you cannot count them, which is the actual problem.
On most New York apartment doors you do not need new hardware. Changing or rekeying the existing cylinders gets you a key nobody else has, usually in one short visit, and the comparison between the two approaches is in rekeying versus replacing a lock. Keep the original cylinder in a bag in the closet so you can put it back when you leave, which is also what protects your deposit, as covered in the end-of-lease lock guide.
If the lease requires the landlord to hold a key, give them one and note the date you did it. If you are upgrading rather than rekeying, the best lock type for a NYC apartment and improving apartment door security cover what is worth paying for on a rental door and what is not. And the rest of the first-week list is in what to do after moving into a new apartment.
Yes, and the time to ask is before you sign rather than after. Many New York landlords rekey between tenants as a matter of course and will confirm it immediately; others do not. Get the answer in an email or a lease rider. If the landlord will not change the lock, you can usually change the cylinder yourself once you take possession, as long as the lease allows it and you give the landlord a key where it requires one.

Whether the entrance door closes and latches by itself without being pulled, lifted, or shoved. A door that needs help to engage the bolt is a door that gets left unlocked, and the cause is usually a sagging hinge or a frame out of alignment rather than the lock itself. That is also the repair most likely to be argued about after you move in.
Changing the cylinder on your own apartment entrance door is common in New York, but read the lease first. Most leases require the landlord or super to hold a key for emergency access, and some co-op and condo buildings restrict what hardware you can fit to a corridor door. Keep the original cylinder so you can reinstall it when you move out.
A rekey or cylinder change on a standard New York apartment door is normally a single short visit, and most apartments need only the cylinders changed rather than new hardware. Bring your lease or another document showing you have the right to be there. Emergency Locksmith NY answers 24 hours a day at (718) 412-1332.
