Except when organizations decide it would be too much of a security risk to give every authorized person keys/cards, or doesn't do so in a timely manner. Then the one designated key-holder is too busy/important to personally let everyone in, so the "secure" door gets propped open and/or opened in response to a knock from anyone, authorized or not. When low-level but authorized staff need access to further secure spaces, they start by tracking down someone with higher access privileges to borrow a card from. People with high-privileged access then start to reflexively toss their credentials to anyone who asks, because most of the time the request is necessary.

Super common with event venues during rehearsals and preparation (below the level of production value where there's a security desk checking IDs).
