Why Elevator “Close” Buttons Rarely Seem to Work in the U.S.
They often appear not to work because U.S. accessibility rules require elevator doors to stay open for a minimum time, and many controllers ignore the Close command for ordinary riders until that window passes; the button is fully enabled mainly in emergency or service modes, and safety sensors frequently override it. In practice, some Close buttons do function—but only under strict conditions that make them feel unresponsive to most passengers.

What the Rules Actually Say
ADA timing requirements
Under the 2010 ADA Standards for Accessible Design (Section 407), elevator doors must remain fully open for a minimum period—commonly at least about three seconds—so people with mobility or sensory disabilities can safely enter. Controllers are programmed so a Close command cannot cut short that minimum “dwell” time. Separately, protective and reopening devices (like infrared light curtains or pressure edges) must stop or reopen doors if a person, mobility aid, or object is detected in the opening. Together, these requirements make any Close command conditional and subordinate to safety and accessibility.
Safety code and local practice
The ASME A17.1/CSA B44 Safety Code for Elevators and Escalators, adopted by most U.S. jurisdictions, does not ban Close buttons; it sets performance and safety criteria. Building owners and elevator companies can choose to limit or disable the button’s effect in normal service, provided door timing and reopening protections meet code. Inspectors verify that timing and protection behave as required; they do not require that Close accelerate doors for general riders.
How Manufacturers Implement the “Close” Button
Modern elevator controllers treat door close commands as one input among many, then apply logic to meet code and safety priorities. That often makes the button’s effect subtle or delayed.
- Minimum dwell enforcement: The controller ignores Close until the doors have been open for the required minimum time.
- Safety sensor priority: If a light curtain detects movement or someone breaks the beam, the doors will not close, regardless of button presses.
- Rate limiting and conditions: Some systems only allow a small reduction in dwell time or require the car to be level, the load within limits, and no new hall calls arriving.
- Service and emergency modes: In Firefighters’ Emergency Operation (Phase II) and Independent Service, Close usually works immediately—often only when pressed and held—to give trained users control.
- Owner preferences: For simplicity or to reduce nuisance complaints, some buildings leave the Close button unwired or effectively disabled in normal operation.
- Destination dispatch systems: In newer “destination control” elevators, door timing is tightly managed by software coordinating multiple cars, further diminishing the Close button’s influence.
The net effect is that the Close button is not a placebo by design, but its authority is deliberately limited so that accessibility and safety always win.
When the Button Does Work
Despite the popular myth, U.S. Close buttons typically do something—just not what many riders expect, and not immediately.
- After the minimum open time elapses, pressing Close can trim a bit of “extra” dwell if no one is entering and no sensor is triggered.
- In Firefighters’ Emergency Operation (Phase II), the Close button is designed to respond right away, often while being held.
- In Independent Service (attendant or freight mode), Close usually provides direct control over the doors.
- Older, pre-1990s installations may respond more aggressively to Close, though many have since been modernized.
- Some brands and building configurations purposefully allow a modest but noticeable acceleration from Close to improve traffic flow.
If you notice an immediate response in a U.S. passenger elevator, you’re likely using a car with more permissive settings, a legacy controller, or a special operating mode.
Why Riders Think It’s a Placebo
Several everyday factors make the Close button feel useless, even when it technically works.
- Pressing too early: If you press before the minimum dwell time ends, nothing happens—and it looks “dead.”
- Sensors doing their job: A foot, bag, stroller, or hand in the light curtain prevents closure regardless of button presses.
- New calls arriving: A hall call at the last second can extend dwell or even reopen doors.
- Dispatch logic: In destination-control systems, the controller may hold doors to coordinate car assignments and load balancing.
- Conservative settings: Owners can lengthen dwell for accessibility or traffic reasons, reducing the Close button’s visible effect.
- Maintenance quirks: Misaligned sensors or minor faults make doors cautious, hiding any effect from the Close command.
These realities create a perception gap: riders expect an instant reaction, but the system is engineered to favor accessibility, safety, and traffic management first.
Practical Tips for Riders
While you cannot override safety or accessibility logic, a few habits can make rides smoother without compromising safety.
- Wait a beat: If you must press Close, do so only after the doors have been fully open for a couple of seconds.
- Keep the threshold clear: Avoid breaking the light curtain with bags or elbows if you want the doors to start closing.
- Use hall calls properly: Calling the elevator once and stepping back reduces last-second reopenings and delays.
- Respect service modes: If an attendant or firefighter is operating the car, let them manage the doors.
- Be patient with destination systems: Follow the kiosk’s assignment; the software will handle door timing to optimize flow.
These practices won’t make Close act like a hard override, but they can help the controller recognize it’s safe to proceed as soon as legally allowed.
Summary
In the U.S., elevator Close buttons often seem ineffective because accessibility rules require doors to stay open for a minimum time and safety sensors override closure whenever there’s a risk. Many controllers ignore or limit Close in normal service, reserving full control for firefighters or independent operation. Some buttons do work—but only after the mandated open period and under clean, obstruction-free conditions. The design prioritizes inclusion and safety over speed, which is why the button rarely behaves like an instant “close now” switch for everyday riders.
Do the close button on elevators work?
You know the closed door button of most lifts doesn’t actually work. A lift doesn’t close faster because you press the close button and the reason behind it will actually blow your mind. Save this reel because this is a lesson in human behaviour and psychology.
Why don’t elevator close buttons work in the US?
In recent years, it has been more common to find door-close buttons that don’t work. Since the 1990 Americans With Disabilities Act, it has become standard for these buttons to no longer have functionality, so that people with disabilities have time to board the elevator.
Do elevator close buttons work in Canada?
Similarly, hitting the “close door” button on an American elevator usually won’t have any effect. But if you’re impatient, it’s good to be Canadian. It turns out that most Canadian crosswalk and elevator buttons actually work.
When did the elevator close button stop working?
This all started in 1990, when the functionality of close door buttons started to be phased out. Why 1990? That’s when the Americans With Disabilities Act was passed. Part of the law said that doors needed to stay open long enough for people in wheelchairs or using crutches to safely board the elevator.
