This clip comes from a Korean short-form video about studio apartments and officetels, whose title warns viewers to change the master password on a digital door lock. That context explains the clean keypad tone: it is the sound of a modern Korean apartment lock rather than a generic movie effect. Short door lock sounds like this circulate widely among creators because they are instantly recognisable, easy to sync to a door opening on screen, and useful in vlogs, home tours, security explainers, and comedy skits where an entrance needs to feel real.

A crisp electronic door lock beep and click from a Korean studio apartment video, used for unlocking doors, entering rooms, and home security edits.
This is a brief electronic door lock sound, just over a second and a half long, built around a sharp keypad beep followed by a mechanical click as the bolt releases. It has the clean, slightly high-pitched tone of a modern Korean digital door lock rather than a rattling old key, so it instantly reads as a secure apartment door opening. In a video it creates a small moment of anticipation and arrival, signalling that someone is coming in, a secret space is being unlocked, or a routine is about to start, without distracting from the dialogue or action that follows.
