A vehicle control apparatus includes a battery remaining-amount recognizing unit recognizing a remaining amount of a battery and a distance measurement control unit measuring a vehicle-terminal distance by switching, based on the remaining amount of the battery recognized by the battery remaining-amount recognizing unit, between a first distance measurement mode repeatedly measuring the vehicle-terminal distance by a distance measuring unit without depending on reception of measurement instruction information transmitted from a mobile terminal and a second distance measurement mode measuring the vehicle-terminal distance by the distance measuring unit in response to reception of the measurement instruction information transmitted from the mobile terminal when communication is established between the vehicle communication control unit and the mobile terminal.

Disclosed is an invention related to a card type smart key. The disclosed card type smart key includes a key main body part having a circuit substrate installed thereinside, a battery cover part having a battery mounted thereon and inserted into an insertion part formed in the key main body part, and a contact part installed in the key main body part so as to be in contact with the battery and having elastic restoration force in the battery side direction.

An electronic key may include a partial capacitor comprising a capacitive metal plate in communication with a processor. The capacitive metal plate of the partial capacitor is configured to form a capacitor with a corresponding capacitive metal plate of a lock when brought into proximity with the metal plate of the lock. Data may be transferred from the key to the lock using a capacitor formed by combining the two metal plates, wherein a common ground is established between the metal plate of the key and the metal plate of the lock through a parasitic capacitance present between the key and lock circuitry. Audit trail data may be recorded based on usage of the key.

An electronic device including a keyless sensor according to various embodiments includes: a case including an opening; a sensor frame provided inside the case and at least partially exposed to an outside of the case through the opening, the sensor frame including a conductive part and a non-conductive part; and a hybrid sensor provided inside the case and accommodated in the sensor frame, wherein the hybrid sensor includes: a base disposed in the sensor frame; a pressure sensor disposed on the base and in contact with the conductive part; and a touch sensor disposed on the base and in contact with the non-conductive part.

The present disclosure relates a set of electronic keys for an electronic lock. The set of electronic keys includes at least one passive electronic key having a passive digital key, and at least one active electronic key having an active digital key. Each of passive and active electronic keys includes a communication channel and an electronic key power supply port. The active electronic key includes electrical power source providing electrical power supply to the active electronic key itself, the electronic lock and the passive electronic key through the electronic lock to operate the electronic lock. When both active and passive electronic keys are inserted into respective electronic keyholes of the electronic lock, both active and passive digital keys are transmitted to the electronic lock, the electronic lock can be locked and unlocked only when both active and passive digital keys received match prestored active and passive digital keys respectively.

A key fob includes: communicator(s), a battery, memory, and processor(s) configured to: find signal strengths of received polls; determine, based on the signal strengths, that the received polls have: (a) increased, (b) decreased, (c) leveled off; and if (a), issue a poll response; if (c), not issue the poll response.

A portable electronic key for use with an electronic locking device comprises a wireless communications module, a processor, and a software application configured to transmit, receive, and respond to electronic messages related to access control information. The electronic messages are formatted according to a request-response protocol. The wireless communications module is configured to use a standardized communication protocol to establish a wireless communications link with a networking device operably associated with a remote administration device located away from the portable electronic key. The software application periodically exchanges, via the wireless communications link, request-response messages related to access control information with a server application of the remote administration device. The processor responds to the exchange of request-response messages by performing at least one of modifying access control information of the portable electronic key or providing access control information of the portable electronic key to the remote administration device.

Provided is a binding device and method of operation of the binding device, with the binding device including a strap including a body, a first area formed inside the body, with a smart key related control circuit disposed in the first area, and a second area formed on one side of the body, with a battery for supplying electric power for operating the smart key related control circuit seated on the second area such that at least a portion of the battery is exposed, and a cover formed to cover the second area.

A module includes a housing including a battery housing portion that houses a battery, an operation accepting unit including a first board including accepting means that accepts an operation and is arranged on the first board, the first board being attached to the housing, and a second board housed within the battery housing portion along with the battery. A control circuit electrically connected to the accepting means is arranged on the second board.

Embodiments relate to enhanced auditing features for administration of remote electronic keys. An electronic key delivers electrical power to an electronic lock to energize circuitry thereof. The electrical power may energize an electric motor or solenoid. Based on access control information associated with the electronic key, an unlocking signal is conveyed from the electronic key that causes the electronic lock to change from a locked state to an unlocked state, thereby permitting a user of the key to access one or more resources secured by the lock. The electronic key stores details related to the unlocking event in memory sites. In some aspects, the electronic key broadcasts a message via a wireless wide area network (WWAN). The message may include a request to establish a WWAN communications link with an access control server located away from the electronic key. Responsive to establishing the WWAN communications link, the electronic key initiates a transfer of data to the access control server, the data including details related to the unlocking event.
