locksmith cutting a building master key at a shop key machine

Manhattan buildings & offices

One key for you.
One key for each tenant.

A master key system gives the super and the managing agent access to every door in the building, while each tenant carries a key that opens only their own. We plan it, cut it, install it, and keep the records so the next key is right the first time.

Serving all of Manhattan from real storefronts since 1988.

How the keying actually works

Every lock in a master system is pinned to accept more than one key. Read it from the top down: the widest key opens the most doors, and the narrowest opens a single apartment.

Own more than one building? A grand master ties the separate building masters together under one key for the owner.

Level 1

Grand master key

Held by the owner or the management company. Opens every door across every building in the portfolio.

Level 2

Building master

One key for the super. Apartments, offices, roof door, boiler room, mail room, compactor closet.

Level 2

Sub master

Narrower access for a porter, a floor, a wing, or a contractor who only needs the mechanical rooms.

Level 3 · change keys

Apt 2R
Apt 4B
Suite 210
Suite 311
Storage

A tenant's key opens their door and nothing else. No tenant key ever passes in a neighbor's lock.

Restricted keyways

When copies should stop at the hardware store

A standard key blank is sold everywhere, so a tenant, a contractor, or a former employee can walk out with a copy and you will never know. A restricted keyway uses a patented blank that only an authorized shop can buy and cut. Copies happen on your say-so, logged against your system, or they do not happen.

  • Move to restricted when you have staff turnover, shared common doors, sublets, or a master key that has been floating for years.

  • Keep it standard when the doors are low risk and you would rather tenants handle their own duplicates at the counter.

  • Mix both. Plenty of our buildings run restricted cylinders on the vestibule, roof and mechanical doors and standard cylinders inside the units.

How we plan a system

The chart matters more than the hardware. Get the chart right and the building runs on it for years. We work the same five steps on a six-unit walk-up and on a full office floor.

  1. 01

    Walk the building

    A locksmith comes to you, opens doors, checks existing cylinders, frames and strikes, and asks who needs to get where. Supers usually know the trouble doors before we do.

  2. 02

    Map the doors

    We build the key chart: every door numbered, every key level defined, and a written answer to who holds what. You approve it before a single cylinder is ordered.

  3. 03

    Pick the hardware

    Standard or restricted keyway, deadbolt grade, mortise or cylindrical, and whether the common doors should move to a keypad. We tell you where spending more is worth it and where it is not.

  4. 04

    Pin and install

    Cylinders are pinned to the chart at the shop, then installed on site and tested door by door with the tenant key and the master key in hand. Keys are tagged and handed over in sets.

  5. 05

    Keep the records

    We hold your key chart on file at the shop. Call two years later for one more key to 4B and it gets cut to code, not copied off a worn original that already sticks.

The rest of the building work

Most master key jobs start with one problem and turn up three more. We handle all of it with the same crew.

Full building rekey on turnover

New owner, new managing agent, or a master key that walked off with a former super. We rekey every cylinder back to a clean chart instead of replacing hardware that is still good.

Reinforced strikes and frames

A strong cylinder in a soft frame buys you nothing. We fit reinforced strike plates, long screws and wrap plates on entry and stairwell doors that take abuse.

Access control and keypads

Keypad and fob locks on vestibules, laundry rooms, gyms and office suites. Change a code when someone moves out instead of collecting keys you will never get back.

Camera and coverage consultation

We will tell you honestly where the locks stop and where a camera earns its keep, so the security budget goes to the doors and corners that matter.

Questions we get from supers and managers

Call the shop if yours is not here. We would rather answer it on the phone than have you guess.

212-510-8320
How long does it take to rekey a whole building?
It comes down to door count and access. We count the doors on the walkthrough, pin the cylinders at the shop ahead of time, and give you a dated schedule before we start. Buildings where tenants have to be home for unit doors take longer, so we book those in blocks.
Can tenants still copy their own keys?
On a standard keyway, yes, anywhere. On a restricted keyway, no. Copies only come from an authorized shop with your written authorization, which is the whole point of moving to one. You decide which doors sit on which keyway.
Can we add doors to the system later?
Yes, and that is why we leave room in the chart when we design it. New storage room, a combined unit, a door that was never keyed: bring us the door and we pin a cylinder that answers to the existing master.
What happens when a tenant loses a key?
Call us with the door and we cut a replacement to the code on file, so it works like the original rather than like a copy of a copy. If the lost key was tagged with an address, we recommend rekeying that one cylinder and issuing a new change key, which does not disturb the master.
Do you work with management companies?
Regularly. We coordinate with the managing agent and the super, keep the key chart on file under the building address, and can be called directly by whoever you authorize for future keys and service calls.
What does it cost?
Pricing depends on door count, keyway and hardware, so we quote after the walkthrough. The quote is itemized and the number you approve is the number you pay.
