Co-op Board Rules for Changing Locks on the Upper West Side
Changing your locks in a UWS co-op? What boards require — approved hardware, key copies for management, and alteration rules.
Most Upper West Side co-op boards do not forbid changing your apartment locks — but they regulate how. The common requirements: hardware from an approved list or of approved type, no changes to the corridor-side appearance, and a copy of every key deposited with management or the super. Some buildings specify the keyway so the building's master key keeps working.
The alteration agreement is your source of truth. Read it before buying hardware, and when in doubt ask the managing agent in writing — a five-minute email beats a violation letter. Interior-side smart locks are the most common gray area; most boards allow them, some want prior approval.
We navigate these rules daily: installing board-compliant cylinders, cutting the management copy, and documenting the work. Tell us your building when you call (646) 469-7112 — there is a good chance we have worked there before.
Frequently asked questions
Can my co-op stop me from changing my locks?
Boards can regulate the type of lock and require a management copy, but outright bans are rare. Check your alteration agreement.
Do I have to give management a key?
Most UWS co-ops require it. We cut the management copy during the same visit.
Will the building's master key still work?
If your building uses a master-keyed system, we install cylinders on the building's keyway so it does.
Do I need board approval for a smart lock?
For interior-side models, usually not — but confirm with your managing agent first.
