In New York City, the landlord pays for rekeying or replacing locks between tenants. That is the baseline rule. Under the warranty of habitability and NYC Housing Maintenance Code, a landlord must provide functioning, secure locks on every apartment door and building entrance. If a lock is broken, worn out, or was last rekeyed for a previous tenant, the cost of repair or replacement falls on the building owner, not you. That said, the picture shifts depending on who caused the problem, what kind of building you are in, and what your lease says.
What is the landlord actually required to provide and pay for?
NYC law is specific. Every apartment entrance must have at least one deadbolt lock and a peephole. Building entrance doors must have self-closing, self-locking hardware. Landlords in rent-stabilized buildings face additional scrutiny because HPD inspectors treat lock deficiencies as class B or class C violations depending on severity.
Here is what the landlord must cover at their own expense:
- Rekey after move-in: A landlord must rekey the apartment before a new tenant takes occupancy. If you moved into a prewar walk-up in Murray Hill and the super handed you the same keys the previous tenant used, that is a violation. Request a rekey in writing. If ignored, file an HPD complaint.
- Broken lock repair: If a deadbolt is malfunctioning through normal wear, the landlord pays. This includes a broken lock on a mailbox, a failing cylinder on the front entry, or a jammed latch on a building door in Tribeca.
- Intercom and buzzer repair: A buzzer not working is not a minor nuisance. It affects building access and is a habitability issue. The landlord is responsible for restoring that access.
- Building access hardware: Broken lobby doors, non-latching vestibule locks, and failing magnetic entry systems on a Chelsea loft building are the landlord's problem to fix.
In rent-stabilized buildings, delays in addressing these repairs can accelerate into formal HPD complaints and rent reduction orders. Property managers overseeing multiple units should treat lock maintenance as a recurring line item, not a reactive expense.
When does the tenant pay, and what happens after a lockout or subletting dispute?
Tenants pay when they caused the damage or made unauthorized changes. If you lost your keys, broke the cylinder forcing entry, or changed the locks without permission, the cost of repair or replacement is yours. Most leases in NYC include language explicitly prohibiting tenants from changing, adding, or replacing any lock without prior written consent from the landlord.
That said, NYC law gives tenants the right to add a second lock. You may install an additional deadbolt on your own door. However, you must provide a duplicate key to the landlord within 30 days. A Schlage B60N or a Medeco Maxim M3 deadbolt are solid choices for this. Both are pick-resistant, commercially rated, and accepted by building management across the Upper East Side and Financial District.
Subletting creates its own complications. If you sublet your apartment and the subtenant changes the locks, you are the one on the hook, not your subtenant. The landlord can charge you for restoring access. Roommate lock disputes follow similar logic: whoever holds the lease is responsible for maintaining lawful access for all occupants.
Lockouts deserve a separate note. If you locked yourself out, the cost of emergency locksmith service is yours. Standard residential lockout service in NYC runs between $75 and $175 depending on the time of day, the lock type, and the borough. A lockout on a Saturday night in the Bronx will cost more than a weekday call in Midtown Manhattan.
One thing a landlord may never do is use a lockout as enforcement. Changing locks, removing doors, or blocking building access to force a tenant to leave is an illegal lockout under NYC Admin Code 26-521. It does not matter if rent is owed. The landlord must restore access immediately and faces civil and criminal liability for refusing.
What should property managers do proactively to avoid disputes?
The most effective way to eliminate tenant-landlord lock disputes is a documented, systematic approach to building security. Property managers overseeing prewar walk-ups in Chelsea, brownstones in the Financial District, or mixed-use buildings in Midtown Manhattan should treat the following as standard operating procedure.
First, implement a master key system. A Medeco or BEST Access master key system gives building management controlled access to every unit while allowing tenants full privacy behind their own keyed cylinders. These systems also provide key control: duplicate keys cannot be cut without authorization, which eliminates the security deposit dispute over unreturned keys.
Second, rekey every unit at every tenant turnover. Use a restricted keyway system so that building supers carry current, auditable access. Document the rekey with a signed acknowledgment from the incoming tenant.
Third, upgrade intercom and buzzer systems proactively. A Liftmaster or ButterflyMX video intercom installed in a rent-stabilized building in Murray Hill reduces unauthorized entry, satisfies habitability requirements, and gives building management a remote access audit trail.
Fourth, know the entry notice rules. In New York, a landlord must give at least 24 hours written notice before entering an apartment except in genuine emergencies. Super entry without notice is a right to privacy violation regardless of what the lease says.

Frequently asked questions
Can a landlord in NYC change my locks without notice?
No. Changing a tenant's locks without a court order is an illegal lockout under NYC Admin Code 26-521. The landlord must restore access immediately. If they refuse, you can call 311, file an HPD complaint, or go to Housing Court for emergency relief.
Do I need permission to change my own apartment lock in NYC?
Yes. You may add or replace a lock, but you must give the landlord or building super a duplicate key within 30 days. Failing to do so can be treated as a lease violation. Use a Schlage B60N or Medeco Maxim and hand a copy to building management in writing.
Who is responsible for a broken buzzer or intercom in an NYC rental?
The landlord is responsible. A non-functional intercom or buzzer compromises building access and can be cited as a violation of the warranty of habitability. File an HPD complaint if the landlord refuses to repair it. A licensed locksmith can replace the entry unit or integrate a new system.
