Commercial Locksmith
Door security in a school or childcare program comes down to three separate jobs, and most sites get into trouble by using one piece of hardware to do all three. The exterior entry has to control who comes in without ever trapping anyone inside. Classroom and activity-room doors need to lock from the inside in seconds without a staff member stepping into the corridor. And back-of-house doors - records, medication, kitchen, mechanical - need ordinary keyed or coded control with a key list that survives staff turnover.
This guide is written for NYC program directors, school building staff and childcare operators who have to make decisions about actual door hardware. It covers what works, what to avoid, and what you cannot legally do to an exit door.

The goal at the front door is simple to state and easy to get wrong: visitors should not be able to walk in unannounced, and everyone inside should be able to walk out instantly.
The hardware pattern that satisfies both is an exit device - a push bar - on the inside, paired with an electrified trim, electric strike or maglock on the outside, released by a staff member after an intercom and camera check. The push bar never stops working. The outside handle is simply dead until someone inside allows entry. Our guide to electric strikes versus magnetic locks walks through which one suits which door, and the panic bar guide covers the push-bar side.
This is where most of the confusion lives. The question staff ask is "how do we lock the classroom quickly?" and the answer is a lock function, not an add-on device.
The hardware designed for this is often called a classroom security or storeroom-style function. It lets a teacher lock the corridor side of the door with a key or a thumb turn from inside the room, while the inside lever always retracts the latch so anyone in the room can leave. No one has to open the door and step into the hallway to lock it, and no one can ever be sealed in.
A whole category of aftermarket products - floor bars, over-the-closer straps, sleeves that drop over a door handle - promise to barricade a classroom door. They are a bad idea in a licensed school or childcare setting, for reasons that have nothing to do with marketing claims.
A barricade device typically needs special knowledge and sometimes two hands to remove, which conflicts directly with the rule that an occupied room's door has to be openable from the inside without a key, tool or special knowledge. It can also lock out the people you most need to let in - responders, or an administrator reaching a child in crisis - and in some cases it can be deployed by a student against staff. A proper classroom-security lock accomplishes the same goal without any of that.
If a barricade device is already on site, treat removing it as a safety fix, not a budget item, and replace the lock function properly.
Licensing inspections and incident reviews tend to land on the doors no one thought about. In a school or childcare program these are the ones to inventory:
We service exit devices, classroom locks, closers and access control for schools, preschools and childcare programs across the five boroughs - including after-hours work so corridors stay clear during program hours.
Staff turnover is high in childcare and support roles, and a single uncontrolled key copy quietly undoes the entire hardware budget. Three practices fix most of it.
Use restricted keys. A restricted keyway cannot be duplicated at a hardware store or kiosk - copies come only from the authorized dealer against a signed authorization. For a site where keys circulate among many adults, this is the single highest-value upgrade.
Build a master key plan rather than a key ring. A designed hierarchy means an aide carries one key that opens only their room, while a director carries one that opens everything - instead of everyone carrying twelve keys and losing track. See master key systems for NYC buildings.
Write down who holds what, and rekey on a trigger. Maintain a key register with names, dates and signatures, and treat specific events as automatic rekey triggers: a key reported lost, a departure that did not return keys, or a change of contractor or cleaning service. Our guide to when a business should change its locks covers the trigger list.
Where keys circulate too widely to control, credential-based access is worth pricing - a lost fob is deactivated in seconds rather than triggering a site-wide rekey. See access control for NYC small businesses.
Two constraints override every security preference, and they are the two most often broken by well-meaning staff.
Free egress. Any door in an exit path has to open from the inside without a key, a tool or special knowledge, and with a single motion. That rules out thumb-turn-plus-lever combinations that need two actions, inside-keyed double cylinders, and every chain, hasp and barricade device.
Accessibility. Hardware on accessible routes has to be operable without tight grasping, pinching or twisting - levers and push-pull hardware rather than round knobs - and closers have to be adjusted so a door is not unreasonably heavy. See accessible door hardware for NYC businesses.
This is general guidance, not legal, code or licensing advice. Schools and childcare programs in New York City answer to several authorities at once - the FDNY and the Department of Buildings on egress and fire doors, and your licensing agency on program-specific requirements - and a locked door that is fine in one occupancy can be a violation in another. Confirm anything you plan to change with the agency that licenses your program and with FDNY or DOB before the work is done.
Twenty minutes, once a term, with a clipboard. Walk every door and check:
Anything on that list that fails is a work order. Most are small - a closer adjustment, a strike reset, a cylinder swap - and they are far cheaper to fix on a scheduled visit than during an inspection or an incident.

A classroom security or storeroom-style function: the corridor side can be locked by a staff member from inside the room, while the inside lever always retracts the latch so anyone in the room can leave. Staff with the right key can still enter from the corridor. No one should have to step into the hallway to lock a door, and no one should be able to seal a room shut.
They are generally the wrong choice and are widely discouraged. Barricade devices usually need special knowledge or two hands to remove, which conflicts with the requirement that an occupied room's door open from the inside without a key, tool or special knowledge. They can also delay responders or be misused against staff. A proper classroom security lock achieves the same goal. Confirm specifics with FDNY, the Department of Buildings and your licensing agency.
Yes, in the sense that the outside handle can be locked or electrified so visitors cannot walk in. What you cannot do is stop people getting out. The inside push bar or lever has to remain free at all times the building is occupied, which is exactly why chains and padlocks on an entry door are never an acceptable shortcut.
Not on a calendar - on triggers. Rekey when a key is reported lost, when a staff member leaves without returning keys, when a contractor or cleaning service changes, or after any break-in. Restricted keys reduce how often this is needed, because copies cannot be made without authorization.
Yes. We run 24/7 across all five boroughs and routinely schedule school and childcare hardware work for evenings, weekends or closure days so corridors and classrooms stay clear while children are on site. Call (718) 412-1332 to arrange a time.
