Abstract
A lock arrangement includes a housing defining a longitudinal axis and a keyway substantially parallel to the longitudinal axis, and a lock cylinder positioned within the housing and extending around at least a portion of the keyway. The lock arrangement also includes a tumbler supported in the lock cylinder for movement relative to the lock cylinder between a locked position, in which rotation of the lock cylinder relative to the housing is prevented, and an unlocked position, in which the lock cylinder is rotatable about the longitudinal axis relative to the housing. One of the locked and unlocked positions of the tumbler is changeable after the tumbler is supported in the lock cylinder to code the lock to a key. The lock arrangement further includes an indicator at least partially supportable in the keyway for showing that a key has been inserted into the keyway to code the lock.
