Can my landlord change the locks on my apartment in New York City?

No. Your landlord cannot change the locks on your New York City apartment without a court order. Doing so is an illegal lockout, which is a civil and potentially criminal offense under New York Real Property Law Section 853. This applies whether you live in a rent stabilized unit in Murray Hill, a prewar walk-up in NoMad, or a loft in Chelsea. The rule is the same across all five boroughs.

What can my landlord legally do with my locks?

A landlord's legal right to touch your locks is narrow. They can rekey or replace a lock if a key is lost and they document the reason, but they must give you the new key immediately. They cannot use a lock change to pressure you out of a unit, respond to a noise complaint, or punish you for filing an HPD complaint.

If your building's intercom or front-door access system is broken, that is a habitability issue. A landlord is required to restore building access promptly. A broken intercom in a Flatiron co-op or a non-functioning key fob system in a Midtown South high-rise both fall under that obligation. Tenants who file a 311 complaint about a broken lock or failed building access create a paper trail that HPD investigators can act on.

The super is also bound by these rules. A superintendent entering your unit, even for a routine repair, must provide proper entry notice, typically 24 hours in writing for non-emergency situations. Emergency access, such as a flooding pipe or gas smell, is the exception. Even then, the super cannot swap your cylinder or add a lock without your knowledge and immediate key handover.

What are my rights if I'm locked out or facing a lock dispute?

If you come home to changed locks, your first call should be to 911. An illegal lockout is treated as a police matter in New York City. Your second call should be to 311 to open an HPD complaint against the property. You can then go to Housing Court and request an emergency order restoring access, often granted the same day.

Rent stabilized tenants have additional protections. Landlords in stabilized buildings face heightened scrutiny for harassment, and a lock change without cause is one of the clearest examples of tenant harassment under the NYC Administrative Code. Document everything: photograph the lock, save all texts and emails, and note the time you discovered the lockout.

Roommate lock disputes are a separate issue. If a roommate changes the lock to exclude you, the same illegal lockout principles apply if you are a named tenant on the lease. If only your roommate is on the lease and you are a subtenant, your rights are narrower and depend on the lease lock clause and the original lease terms. In either case, do not force entry. Get legal help or a court order first.

The repair-and-deduct remedy, which lets tenants fix something and subtract the cost from rent, is rarely the right move for lock issues. New York courts apply this remedy inconsistently, and withholding rent without legal cover can jeopardize your tenancy. File the HPD complaint and let the housing court process work.

What should happen with locks when I move in or move out?

When you move into a new apartment, whether it is a brownstone in Chelsea or a doorman building near the Flatiron, you have the right to request a rekey. The previous tenant may have shared keys with friends, family, or service providers. A responsible landlord will rekey the unit between tenancies. If yours does not, you can ask for it in writing. Many landlords resist, but the request is reasonable and documents your concern.

For the rekey itself, a Schlage B60N or a Medeco M3 cylinder are both reliable choices for residential apartment doors in Manhattan. The Schlage B60N is a solid mid-range deadbolt with affordable hardware and professional rekeying costs that vary by cylinder type. A Medeco M3 offers restricted keyways and bump resistance, with cylinder replacement running considerably more due to the higher-security design. Either is appropriate for a prewar walk-up. For a loft with a wider door frame, a Grade 1 Schlage B562 with a double cylinder may be more suitable.

At move-out, your lease may include a key handover clause requiring you to return all copies. Failure to do so can be cited as a reason for a deduction from your security deposit. Landlords are not permitted to deduct for normal wear on locks, but a replaced or damaged cylinder is a different matter. Return all keys, including copies you had made, and get a signed receipt.

If you are an office manager or retail tenant in a Midtown South or NoMad commercial space, the same framework applies to your storefront, though commercial lease terms can vary more widely. Review your lease lock clause carefully before making any changes to the existing hardware.

Frequently asked questions

Can my landlord lock me out for not paying rent in NYC?

No. A landlord cannot legally lock you out for unpaid rent or any other lease violation without going through Housing Court and obtaining a court order. Changing your locks or removing your belongings without a court order is an illegal lockout under NYC law, and you can sue for damages and immediate reentry.

How much notice does my landlord need to give before entering my apartment?

New York law generally requires at least 24 hours written notice before a landlord enters your apartment for non-emergency reasons such as repairs or inspections. Emergency access, such as a gas leak or burst pipe, is the main exception and requires no advance notice.

What should I do if I come home and my locks have been changed?

Call 911 and report an illegal lockout. Then call 311 to file a complaint with HPD. You can also go directly to Housing Court and request an emergency order restoring your access, often on the same day. Document everything with photos and keep all written communications from your landlord.
