  • Publication number: 20250122751
    Abstract: A combination lock can be operated manually via the manipulation of rotatable dials and by way of a key, such as an electronic key. The lock includes one or more rotatable dials each having multiple indicia disposed thereon. Rotation of the rotatable dials to predetermined indicia places the lock in the unlocked position. The lock can further include an electronic port and an actuator. Upon receipt of a predetermined credential via the port, the actuator can place the lock in in the unlocked position. The lock further includes a knob assembly that, when the lock is in the unlocked position, can be rotated between a first position in which the lock is in a latched position and a second position in which the lock is in an unlatched position. The combination lock may automatically scramble the positions of the dials upon opening for security purposes.
