"Nation's Eldery Hit Hard By Closing Automatic Doors."

Technology has proven to be quite useful over the years, and none more so than the automatic door, which has helped remove the need for people to physically open doors. However, like all technology, automatic doors have an opportunity to go wrong at the worst times, usually by opening or closing when they are not intended to or just refusing to open at all when they should.

This can be Played for Laughs by having someone suffer Amusing Injuries by virtue of being in the way of the doors when they close on them. However, this can also be Played for Drama, either by having the person suffer serious injury (usually by having their fingers seriously harmed from within the door), trapping them in a dangerous location, or even outright killing them depending on the force of the door closing. The exact reason for this varies — sometimes, it's a simple malfunction, but other times, it may be engineered by a third party, usually either to cause mayhem, trap the person in a needed location, or as a way of killing them. Sometimes, the doors may get broken as a result of a person not realizing that they're automatic and trying to force them open manually.

Compare Door Slams You. May also be exploited by someone as a form of Door Judo, Tactical Door Use, or Tae Kwon Door. If the automatic doors belong to an elevator, it may lead to Elevator Failure.

The door does open and close silently for him—then immediately afterward, loudly asks Zaphod if that was quiet enough for him.

    Live-Action TV 
  • The Brittas Empire:
    • In "Opening Day", the automated doors leading to the centre begin to malfunction, closing and opening when they shouldn't and at one point trapping the baby carriage containing Carole's son Ben between the doors. It's a bit of a problem as it's meant to be the opening day for the Leisure Centre and it's not helped when Brittas kicks out the person meant to fix it under the belief that he was Laura's friend Michael with a grubby dress sense. Eventually, Michael does show up, gets trapped within the doors, and gets electrocuted trying to reach the opening mechanisms for the door, trapping everyone inside as a result.

  • Odd Squad:
    • Invoked by O'Brian in "Life of O'Brian". He accepts Olive's apology about her throwing a basketball that accidentally hit him on the head, but refuses to accept her apology about "the other thing" she did.

He ends up opening them again when she sarcastically thanks him and tells him he's making her day.
    • In "There Might Be Dragons", a power failure in Headquarters causes the automatic doors to stop working, including the doors in the tube lobby (which Otto ends up slamming into when he tries to walk through them) and the doors leading into the bullpen.

  • Star Trek:
    • Star Trek: The Next Generation: In "Contagion", the Enterprise crew witnesses its sister ship, the Yamato, explode with all hands lost due to a failure of its antimatter fuel containment.note  The clue leading them to the cause is within the Yamato Captain's personal log; a long-abandoned planet known as Iconia, and an alien scanning probe that the ship encountered while in orbit. As the Enterprise travels towards Iconia, they begin having systems problems, including the invoked trope of the automatic doors failing at random times. When they arrive, the Enterprise encounters an identical probe launched from the surface, and Captain Picard plans to tractor it into the ship to study it. Geordi, suddenly discovering the cause of the malfunctions, desperately tries to hail the bridge, but the communication systems go down at that very moment. The trope is then invoked for drama, as he also tries to use a turbolift in Main Engineering to quickly get to the bridge, but the doors fail to open there as well. Geordi is only able to just get to the bridge in time, after being thrown about in the malfunctioning turbolift on his way, to warn Picard and the bridge crew of the danger that the probe poses.
    • An episode of Star Trek: Voyager has Seven of Nine make some modifications to Voyager's computer, causing a number of malfunctions on board the ship.

    Video Games 
  • This is a recurring obstacle in the Dead Space games, requiring Isaac to use his Stasis module to slow said malfunctioning doors down, lest he risk being smashed to pieces by them.
  • The hacking system in FTL: Faster Than Light can send a drone to target one of the enemy ship's systems, additionally shutting the doors leading to that system, forcing the ship's crew to use firepower to breach them while opening for potential boarders. Using a hacking drone on the ship's door system allows for applying that effect to all the doors on the ship.
  • Instinct contains a lethal version in one of the labs, where a malfunctioning, automated sliding door covered in blood crushes everything that tries crossing and turning zombies coming from the other room into a pile of red stuff. You'll need to find a control panel to stop said door momentarily before dashing through, but take note that said door can suddenly reactivate and squash you.
  • One of Yakuza 4's Revelations sees a drunk salaryman wearing a Necktie Headband confronting a young punk harassing a woman. While he exits the Poppo convenience store, the tie gets caught onto the automatic sliding door behind him, which causes the salaryman to fly backwards, delivering a kick into the punk's face, and the salaryman to fall flat on his back, with the automatic doors trying to close in on him. It gives Saejima the Essence of Clotheslining and Kiryu the Essence of Taunting.
