My landlord won't fix my apartment lock - what can I do in NYC?

Your landlord is ignoring a broken deadbolt, a malfunctioning buzzer, or a lock they changed without warning. In New York City, that is not just an inconvenience - it may be a violation of your lease, the warranty of habitability, and in serious cases, state law. You have options, and most of them do not require a lawyer to start.

What does NYC law actually require landlords to do with locks and building entry?

New York City's Housing Maintenance Code requires landlords to maintain secure building entry at all times. That means a functioning front door lock, a working intercom or buzzer system, and operable locks on every apartment door. These are not optional amenities. They fall under the warrant of habitability, the legal standard that applies to every residential lease in the state, including rent stabilized apartments in buildings throughout NoMad, Flatiron, and Murray Hill.

If your buzzer is not working or the intercom has been broken for weeks, your landlord is in violation. The same applies to a deadbolt that no longer latches, a cylinder that spins freely, or a lock the super damaged during an unannounced entry. You can file an HPD complaint online at nyc.gov or by calling 311. HPD will schedule an inspection and issue a violation if the condition is confirmed. That violation creates a paper trail that matters if you ever need to withhold rent or pursue a repair-and-deduct remedy.

On the question of super entry: your landlord or superintendent has the right to enter your apartment for repairs, but they must give reasonable advance notice except in a genuine emergency. They cannot use that access to inspect your lock, copy your key without consent, or swap hardware without telling you. If a Schlage B60N or Medeco M3 deadbolt you installed yourself was replaced without your knowledge, that is a serious overstep and potentially an illegal lockout.

What can you do if your landlord locks you out or changes your lock without permission?

A lockout by landlord - meaning your landlord changed your lock or withheld a working key to force you out - is illegal under New York Real Property Law Section 853. It does not matter if you are behind on rent, in a subletting dispute, or in the middle of a lease renewal negotiation. Self-help eviction is not legal in New York, full stop.

If you are locked out right now, your first call is to restore access. A locksmith can pick or bypass most residential cylinders and replace the hardware on the spot. In a prewar walk-up in Chelsea or a loft building near Flatiron, that typically means replacing a worn Kwikset deadbolt with a Schlage B60N or stepping up to a Medeco Maxum for added pick and drill resistance. Once you are back inside, document everything: photograph the new cylinder, keep any text messages from your landlord, and note the date and time.

After access is restored, you have several legal paths. You can file an HP action in Housing Court to compel the landlord to restore your access and pay damages. You can file a 311 complaint for the illegal lockout. If you are in a rent stabilized building, you can also contact the New York State Division of Housing and Community Renewal. None of these require you to move out first or abandon your claim to the apartment.

A separate but related issue is the roommate lock dispute. If a roommate changed the lock and excluded you, the same principle applies: only a court order can terminate your right to occupy. Document the situation and seek an emergency order to show cause in Housing Court if your roommate refuses to provide a key.

What are your rights around rekeying, duplicate keys, and lock changes in your own apartment?

NYC tenants have an explicit right to change or rekey their apartment lock under Multiple Dwelling Law Section 51-c. You do not need the landlord's permission. You do need to provide a duplicate key to the landlord or their agent upon written request within a reasonable time. This is not a loophole for your landlord to get a key whenever they feel like it. It is a formality triggered by a written ask, and it does not give them the right to enter without notice.

The practical takeaway: rekey after every move-in. You have no way of knowing how many duplicate keys the previous tenant made, who still has a copy, or whether the building super retained one after a repair visit. A locksmith can rekey a Medeco M3 or an ASSA Abloy cylinder the same afternoon you get your keys. If your building uses a Schlage B60N, rekeying is fast and inexpensive relative to a full lock replacement. If you want to upgrade at the same time - for example, moving from a standard pin tumbler to a Mul-T-Lock MT5+ for higher security in a Midtown South co-op - that is entirely within your rights.

At move-out, the rules flip. You are required to hand over all keys, including any duplicates you made. Key handover at move-out should always be documented in writing. If you return keys and the landlord later claims they need to change the lock, they cannot automatically charge that to your security deposit without proving the need. Get a signed receipt for every key you return.

If your landlord is stonewalling on a broken lock, an illegal entry, or access they cut off without cause, document the condition and contact NoMad Locksmith & Security at (917) 337-9703. We work across NoMad, Flatiron, Chelsea, Murray Hill, and the rest of Manhattan, and we can restore access, upgrade your hardware, and give you a written record of the work that holds up if you end up in Housing Court.

Frequently asked questions

Can my landlord legally change my lock without telling me in NYC?

No. A landlord changing your lock without notice or a court order is an illegal lockout under NYC law. You have the right to immediate re-entry. Call 311, file an HPD complaint online, or call a locksmith to restore access, then document everything for an HP action in Housing Court.

Do I have the right to rekey my apartment lock after moving in?

Yes. NYC law gives tenants the right to rekey their lock without landlord permission, as long as you provide a duplicate key to the building owner or super upon written request. A locksmith can rekey a Medeco M3 or Schlage B60N the same day you move in.

What happens to my locks and keys when I move out?

You are required to return all keys to the landlord at move-out. Failure to do so can result in a deduction from your security deposit for a lock change or rekey. Get a written receipt for every key you hand over and photograph the lock hardware before you leave.
