In most New York buildings with a doorman, the front desk can get you off the sidewalk and up to your floor, but it cannot open your apartment door. Staffed buildings frequently hold no apartment keys at all, and the ones that do have rules about who may use them and when. The lobby is solved in thirty seconds. The door to your own unit is a separate problem with a separate answer.
A lockout in a walk-up is one door. In a staffed elevator building it is usually three, and they fail in different ways.
Knowing which door you are actually stuck at is the whole of the triage. If you are standing in a warm lobby with a staff member who already recognizes you, the good news is that you are safe and the problem is narrow. The bad news is that the narrow problem is the one nobody in the building has a key for.
Residents are often surprised that a building with a staffed desk twenty-four hours a day keeps no copy of their key. It is a deliberate choice, not an oversight. Holding keys for a hundred and fifty units means somebody has to store them, log them, control who opens the cabinet, and answer for it if a key goes missing or an apartment is entered when it should not have been. Plenty of managing agents look at that and decide the cleanest policy is to hold nothing.
Where a building does keep keys, it is usually voluntary - residents who want staff to let in a dog walker, a contractor or a relative sign one in. That key lives in a locked cabinet or a numbered lockbox, and the list of people who can open it is short. Key lockbox safety and what happens to key control when a super leaves both get into how those systems go wrong over time.
One more thing worth knowing: a key the building holds is not the same as a master key. Apartment doors in a New York building are very rarely on the master key system. The master usually covers common doors - the roof, the compactor room, the stairwells, the mechanical spaces - and stops at the apartment threshold.

You are in the minority, and it still is not automatic. Three things normally have to line up before a staff member walks your key upstairs.
That last one is why the same question gets two different answers twelve hours apart. It also explains the most common wasted hour in a staffed-building lockout: a resident waits for a super who is off duty until seven, when a locksmith could have been on the floor long before. Night lockouts run on this exact pattern.
Short, specific questions get you an answer instead of a shrug. Ask them in this order.
Make that fourth call while you are still asking the first three. Our arrival time across the city is typically around fifteen to twenty minutes, which is usually shorter than the wait for a superintendent who is off shift, and nothing is lost if the key turns up first. Whether your super has a key walks through the same decision from the other direction.
We work in staffed and doorman buildings across Manhattan, Brooklyn, Queens, the Bronx and Staten Island, around the clock. Licensed and insured, and used to signing in at a front desk.
A doorman knowing your face does not remove the locksmith's obligation to establish that the person asking for the door to be opened is entitled to go through it. That check exists to protect you, because the day it stops happening is the day anyone can have your door opened by saying your apartment number with confidence.
In practice a staffed building makes this easier rather than harder. The desk can confirm your name against the unit on the spot, which covers the part that is usually hardest when your wallet is on the other side of the door. Bring whatever else you have - a photo of your lease on your phone, mail with your name on it, a banking app showing the address. What identification a locksmith needs covers the full picture, and avoiding locksmith scams explains why nobody asking is the real red flag.
Getting the door open is yours to authorize. Replacing hardware is where the building has a say, and the answer differs by ownership type.
Changing locks in a co-op versus a condo sets out the differences properly. If your keys are gone rather than merely inside, lost apartment keys explains why a rekey usually beats living with a key that is somewhere in the city.
In the overwhelming majority of apartment lockouts, no. The usual route is to work the existing lock open and leave the hardware functioning exactly as it was, which matters more than usual on a corridor door the board has opinions about. Where a cylinder is already failing, or where a high-security lock is doing precisely what it was bought to do, the honest answer may be that a cylinder gets replaced - and you should be told that before the work starts, not after. How a locksmith opens a door without damage covers the methods.

Often not. Many New York buildings deliberately hold no apartment keys at all, because storing them creates a responsibility the managing agent would rather not carry. Others keep keys only for residents who chose to leave one, usually in a locked cabinet that one or two staff members can open. Ask your management office what the policy is long before you need the answer.
Only if the building holds a key for your unit and house policy allows a staff member to use it. Even then it usually means leaving the desk unattended, which a lot of buildings do not permit on an overnight shift, so the honest answer can be no at three in the morning and yes at ten the next morning. The building entrance is a different question - staff can nearly always get you through that.
Yes. A doorman vouching for you is genuinely useful and counts as supporting evidence, but a professional locksmith is still going to establish that you have the right to be behind that door. In a staffed building the front desk confirming your name and unit is usually the fastest part of that check rather than an obstacle to it.
To open it, no - it is your apartment and you are the resident. Changing the lock is where the building gets involved, because many leases and house rules require that management be notified, and co-ops and condos often have their own hardware requirements on top of that. Tell your locksmith what kind of building you are in before anything gets replaced.
The lock work itself is normally the short part. What adds time is the back-and-forth with the front desk before anyone touches the door, plus a high floor served by one elevator that is tied up with a move. Calling a locksmith at the same moment you ask the desk about a key, instead of an hour later, is what actually shortens the night.
