An interlock system comprising: a first lock including a first lock memory configured to store one or more virtual keys; and a first key including a first key memory configured to store one or more virtual keys, wherein the first lock is configured to be actuated between a first condition and a second condition, when a first virtual key stored in the first key memory is transferred to the first lock memory, by engagement of the first key and first lock, and movement of the first key with respect to the first lock.

A locking key for changing a locked state by being inserted into a key box includes a first base including a metal complex and in which a first pattern groove is formed, and a first pattern provided in the first pattern groove and including a conductive material.

A dual authentication system of an electronic locking device using an electronic key according to an exemplary embodiment of the present invention includes a receiving unit that receives UID data pre-stored in the electronic key and encoding data generated by an input of a button provided in the electronic key, when a terminal portion provided in a key head of the electronic key is in electrical contact with a data communication unit of the electronic locking device; an authentication unit that performs dual authentication based on the UID data and the encoding data; and a command unit that commands the unlocking of the electronic locking device when the dual authentication on the UID data and the encoding data is successfully performed.

A door handle with electronic lock assemble comprises a door handle and a connecting rod. The door handle is deposited on a side of a door. The connecting rod is rotatable mounted on the door handle by crossing through the door. The door comprises a lock operatively connected with the door handle and the connecting rod. The door handle comprises an electronic module mounted therein. The electronic module comprises a controller, an actuator module and an electronic key interface. The controller and the actuator are signal connected. The electronic key interface is electronic connected with the controller.

A locking device that can be mounted into a rotating or swinging door is disclosed. The locking device can have a deadbolt. The locking device can detect the position of the deadbolt and/or whether the door is closed. The locking device can have a camera, microphone and speaker. The locking device can send images detected by the camera and audio detected by the microphones to a remote computer.

A portable communication device that can suppress degradation in communication efficiency caused by a reduction in device size. The portable communication device includes a mechanical key that is made of an electrical conductor and is for mechanically locking or unlocking a door of a vehicle, and a transmission antenna for transmitting a wireless signal. A storing portion that stores the mechanical key is provided in a case in which the transmission antenna is provided. When the mechanical key is stored in the storing portion, the transmission antenna is electrically connected to the mechanical key. In the portable communication device, the storage state of the mechanical key in the storing portion is detected by a push switch, and impedance correction in a communication circuit is performed by an impedance matching circuit in accordance with the detection result.

A tamper resistant lock. A lock has a lock housing with housing indentation. A cylinder is rotatably housed within the housing. A locking pin is connected to the cylinder and is inserted into the housing indentation when the lock is in a locked position and the locking pin is clear of the housing indentation when the lock is in an unlocked position. An anti-tampering mechanism is positioned between the housing and the cylinder. The anti-tampering mechanism receives a user's key and also includes a relative motion hole. A key extension portion is rotatably inserted inside the anti-tampering mechanism body and includes a relative motion indentation. The key extension portion is keyed to the cylinder. A lock ball is inserted into the relative motion hole and the relative motion indention, thereby preventing relative motion between the anti-tampering mechanism body and the key extension portion. A flexible band is wrapped around the anti-tampering mechanism body and covers the lock ball and holds the lock ball in place in the relative motion hole and relative motion indentation. The flexibility of the flexible band is sufficient to permit the lock ball to leave the relative motion indentation while simultaneously retaining the lock ball in the relative motion hole if the anti-tampering mechanism body is rotated while the locking pin is inserted into the housing indentation, thereby permitting relative motion between the anti-tampering mechanism body and the key extension portion. In a preferred embodiment the tamper resistant lock is a padlock.
