Apartment lock change costs in NYC break down like this: a typical locksmith visit is built from a service call fee (higher after hours), labor, and the lock hardware itself — the line that varies most, from basic knob locks up to high-security and smart models. A standard deadbolt swap on one door is the cheapest version of the job; a high-security or smart lock upgrade sits above it. And if your existing locks are in good shape, rekeying — resetting the pins so old keys stop working — costs a fraction of a full change. What makes NYC apartments different from the national picture isn’t just the rates: it’s the landlord and lease rules that come with changing a lock on a rental. Here’s the full cost breakdown, plus the tenant rules that protect your security deposit.
NYC apartment lock change costs at a glance
| Item | What drives the price |
|---|---|
| Typical locksmith visit, all-in | Lock grade plus the timing of the call |
| Service call fee (daytime) | The baseline — scheduled weekday visits cost least |
| Service call fee (after hours) | Nights, weekends, and holidays bill at a premium |
| Lock hardware, per lock | Basic knob locks up to high-security and smart models |
| Rekeying instead (typical apartment, 2–3 cylinders) | see rekey guide below |
If your goal is simply that old keys stop working — after a move-in, a lost key, or a roommate change — check our apartment rekey pricing guide before paying for new hardware: a typical NYC apartment rekey with new keys costs far less than swapping in new hardware.
What drives the price of an NYC apartment lock change
- The lock itself. A standard deadbolt or knob lock sits at the low end of the hardware scale; pick-resistant high-security cylinders and smart locks sit at the top. Many NYC apartment doors carry two or three keyholes — knob lock, deadbolt, sometimes a high-security cylinder — so count keyholes, not doors, when you call for a quote.
- Timing. A scheduled weekday appointment is the cheapest option. Late nights, weekends, and holidays trigger the higher after-hours service band — the premium you pay for a 24/7 emergency locksmith response.
- How many locks. Changing every lock in a new apartment costs more than one front-door swap, but bundling them into a single visit earns a better rate — you pay the service call once.
- Building requirements. Some co-ops and condo buildings require specific lock types, keyed alike to building master systems, or landlord approval before hardware changes. Check before buying anything.
Rekey or replace your apartment locks?
Rekey when the hardware is in good condition and the problem is who has keys — the classic move-in scenario. The locksmith changes the internal pins so every old key is useless, and the lock’s strength is unchanged. Replace when locks are old, damaged, or you want a genuine upgrade: a high-security deadbolt for a street-facing door, or a smart lock for keyless entry. Replacement costs more up front but is the right long-term call for worn hardware; our lock change service page covers the hardware options, and a residential locksmith can tell you in one look which route your door actually needs.
Renters: the rules that protect your deposit
Changing locks on an NYC rental involves more than hiring a locksmith — the lease and state law both have a say.
Check your lease first
Most NYC leases have a clause covering alterations and lock changes. Read it before you book anything: unauthorized changes can lead to charges or friction with your landlord, and lease agreements are written to spell out exactly these responsibilities.
Give your landlord a duplicate key
In New York, tenants must notify the landlord of any lock change and provide a duplicate key. This isn’t a courtesy — landlords need emergency access for fires, leaks, and repairs, and withholding a key can put you in violation of your lease.
Protect your security deposit
If you change locks without permission or never hand over the new key, your landlord may deduct the cost of a new lock set — or an emergency locksmith visit to gain access — from your security deposit. A quick email documenting the change and a key handoff costs nothing and protects hundreds of dollars.
You still have the right to feel safe
If a key was lost or you’ve had a break-in, you have a legitimate reason to change or rekey the locks, and a reasonable landlord should be receptive. Follow the process — notify, provide the key, keep it documented — and you get the security without the dispute.
How to pay less for the same security
- Get two or three quotes and ask each for the total including the service fee — comparing totals, not teaser rates, is how you spot outliers.
- Schedule during business hours. The gap between a daytime and an after-hours service call is the easiest money you’ll ever save.
- Do all the locks in one visit. One trip fee, multi-lock rate.
- Don’t reuse worn hardware. Reusing old screws and strike plates with a new lock weakens the whole setup and invites a second repair bill.

Frequently asked questions
How much does it cost to change locks in an NYC apartment, bottom line?
The total combines a daytime service call, labor, and hardware priced by grade. A single standard deadbolt is the cheapest job; multiple locks or premium hardware cost more. Call (212) 204-1655 for a precise quote for your apartment door.
Is rekeying cheaper than changing the locks?
Almost always. Rekeying keeps your existing hardware and makes old keys useless — a typical NYC apartment rekey costs a fraction of what new hardware and installation run. Replace only if the hardware is worn, damaged, or due for an upgrade.
Do I really have to give my landlord a key?
Yes. New York law requires tenants to notify the landlord and provide a duplicate of any new key. Skip it and you risk lease violations and deductions from your security deposit if the landlord needs emergency access.
What do NYC locksmiths charge after hours?
The service call fee rises to a premium band for nights, weekends, and holidays, on top of labor and parts. If the job can wait until a weekday morning, it should.
Can I save by changing all my apartment locks at once?
Yes — one service call fee covers the visit, and most locksmiths price additional locks at a better rate. Front door plus a secondary lock in one appointment beats two separate bookings.
