Auto-relock tumbler

From Memory Alpha, the free Star Trek reference

An auto-relock tumbler is a type of lock that automatically relocks itself after a short time if not opened completely or left unlocked. It is often found on safes and car doors.

The safe in the counting room of Vic Fontaine's casino had an auto-relock tumbler, making life difficult for the safe-cracking janitor Nog. (DS9: "Badda-Bing, Badda-Bang")
