relock
Fasten shut anew
To relock is to lock again something that was previously locked, then unlocked: I relocked the door after letting the cat out.
The term appears in security contexts—phones, safes, doors—where restoring a locked state matters: The phone will automatically relock after thirty seconds of inactivity.
