A package room is a second front door, and most New York buildings secure it like a closet. The hardware that works is a self-closing, positive-latching door with either a mechanical pushbutton lock on a low-value room or a credential reader with an audit trail on a room worth stealing from - never a padlock, never a propped door, and never a key that half the block already has a copy of. The harder problem is not the lock. It is who holds the code, the fob or the key after the last three supers, porters and couriers moved on.
A New York building's delivery problem used to be a pile of boxes behind the vestibule radiator. Now buildings convert a stroller room, a former laundry, a basement closet or a slice of the lobby into a package room - and the conversion almost always happens faster than the hardware decision. The room ends up with whatever door was already there, a hollow-core slab with a storeroom knob or a hasp and padlock, guarding thousands of dollars of other people's property.
Two things make it worse in the city specifically. Deliveries arrive while nobody is home, so the room is the only thing between the courier's drop and the resident's pickup. And because the room sits inside the secured envelope, everyone assumes the building front door is doing the work. It is not - a front door buzzed open twenty times an hour by residents who cannot see who is downstairs is not a barrier. See how buzzer and intercom systems actually control entry and what happens when the building front door lock is broken.
Before picking a lock, be honest about how couriers reach the room today. Each route has a different failure mode.
There is no single right answer. There is a right answer for your building's traffic, staffing and tolerance for administration.

We get called to package rooms where the hardware is fine and the room is still wide open, because the door never closed. Three things decide whether a package room door is ever actually locked.
That last point is where DIY package-room security goes wrong most often. Adding a deadbolt, hasp or chain to an interior door in a residential building can create an egress problem and a code violation at once, and in a basement conversion it can sit directly on the path people would use to get out. If the room is on an exit route or the door is part of a rated assembly, that is a conversation to have before buying hardware.

A package room lock is only as good as the list of people who can open it, and in a New York building that list changes constantly - supers move on, porters rotate, managing agents change, vendors each got something at some point, and residents move out without anyone asking for the fob back. Treat that list as a living document with a named owner, and set a rule for when it gets rebuilt rather than patched:
If the building runs a master key system, decide deliberately whether the package room belongs on it. Putting it under the building master is convenient for staff and means every master key holder - past and present - can also open the room. Keeping it off the master means more keys to carry and a smaller circle of access. Both are defensible; drifting into one by accident is not. See how master key systems are planned in NYC buildings.
One budgeting note: the expensive part of a package room upgrade is rarely the lock. Cost climbs when the door itself is wrong - a hollow slab in a frame that has dropped, a failed closer, a strike that was never reinforced - because hardware cannot be better than what it is mounted in. And if the real complaint is missing mail rather than missing parcels, the package room is the wrong target; the mailbox bank is - see mailbox lock replacement in NYC.
For most New York buildings, an electronic keypad supporting individual user codes. Each resident, porter and vendor gets their own code, one person can be removed without disturbing everyone else, and many models record entries. Small, low-value rooms can run a mechanical pushbutton lock if the code is changed on a schedule.
It is not a good solution in an occupied building. A padlock and hasp get left hanging open, prevent the door self-closing properly, and on a door that sits on an exit path can create an egress problem. A proper latching lock on a self-closing door does the job without those trade-offs.
Immediately whenever a staff member leaves or a credential is lost, and on a calendar otherwise - quarterly is a reasonable floor for a shared mechanical code. Shared codes leak steadily rather than all at once, so waiting for evidence of a leak means acting too late.
That is a deliberate decision, not a default. On the master it is convenient for staff, but everyone who has ever held a master key can open it. Off the master the circle is smaller and there are more keys to manage. Decide it rather than inherit it.
Not entirely. Lockers handle most parcels well and give each resident a single-use code, but oversized boxes, furniture and grocery deliveries still need somewhere to go. Most buildings that install lockers keep a controlled room for the overflow.
Usually yes. Most pushbutton and keypad locks fit standard door preparations, so the work is a visit rather than a project. The limits are the condition of the door and frame, the closer, and whether the door is part of a rated assembly or sits on an exit path. Call (718) 412-1332 with a photo of the door and frame.
