  • Dual function lock cylinder assembly operable by different keys
    Patent number: 10253526
    Abstract: A lock cylinder assembly includes a housing, a first cylinder disposed within a first bore formed in the housing, and a second cylinder disposed within a second bore formed in the housing, in which at least one of the first and second cylinders is an electronic cylinder. The lock cylinder assembly further includes first and second cams, in which each of the first and second cams are configured to actuate a door lock mechanism. The first cam is directly connected to the second cylinder so as to be rotatable with the second cylinder. The second cylinder and the second cam are rotatable with respect to each other so that the second cam does not rotate with the second cylinder. The second cam is rotatably coupled to the first cylinder so that the second cam rotates when the first cylinder is rotated.

  • Electronically-controlled removable core lock
    Patent number: 8973417
    Abstract: An electronic small format interchangeable core (“SFIC”) lock is configured so that core locking features are electronically controlled, and keys can be electronically programmed to operate either as a normal user key able to open the lock or as a control key able to open the lock and to remove the SFIC cores. The same key will operate as a normal access key or as a control key, depending on how the key is programmed.

  • Key and lock device
    Patent number: 7099474
    Abstract: A key and lock device comprises a key having a first electronic circuit and a lock having a second electronic circuit. The key and the lock store secret information, some of which is unique for each device. The key and the lock exchange a random number through connectors and perform a calculation in the respective circuitry based on the random number and secret information. An electrical blocking mechanism is moved to a non-blocking position if a comparison of the calculations in the circuits gives the correct result.
