A remote access device and methods of operation thereof are provided for accessing a physical object or location. The remote access device includes an accelerometer, a wireless transmitter, and control circuitry. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a first change in motion states of the remote access device. The control circuitry causes the wireless transmitter to transition between a first operating mode and a second operating mode in response to receiving signals from the accelerometer indicating a second change in motion states of the remote access device. The control circuitry further causes the wireless transmitter to transition between the first operating mode and the second operating mode in response to receiving signals from the accelerometer indicating a third change in motion states of the remote access device.

According to one embodiment, a method of conserving energy while seeking to wirelessly actuate an access control using a mobile device is provided. The method including: searching for a wireless signal at a first rate; detecting a wireless signal; generating a zone of interest; detecting positional data of a mobile device; and searching for a wireless signal at a second rate greater than the first rate when positional data of the mobile device indicates that the mobile device is within the zone of interest.

Provided is a system and method for duplicating a master key for a vehicle. The system includes determining that a first device is communicating with a t/r device, the t/r device including an antenna for communicating with the master key. A cloning application associated with said t/r device may be operating on the first device. The t/r device may retrieve security information from said master key. The cloning application may communicate the security information for said master key to said central network system. The central network system may generate duplicate security information. The central network system may communicate the duplicate security information to the cloning application. The cloning application may transmit the duplicate security information to the t/r device to program a duplicate master key with the duplicate security information.

Lock systems are disclosed. The lock system may include a lock unit and a separate base station. The lock unit may include one or more components maintained in a powered-off and/or low-power standby state when not in use. The lock unit may include a sound receiver. The lock unit may activate power to one or more components unit after detecting a predetermined activation sound transmitted by a sound transmitter on the base station. The lock unit and base station may include wireless communicators to communicate signals and/or information between the lock unit and base station after the lock unit is powered on. To conserve power, a lock unit may power down after a predetermined action has been completed, communication of a power down signal, and/or after a predetermined time period has elapsed.

It is provided a protection device for being provided inside a key fob to selectively inactivate the key fob. The protection device comprises: a first conductive layer; a second conductive layer; an insulator layer between the first conductive layer and the second conductive layer, the insulator layer preventing conductive contact between the first conductive layer and the second conductive layer; and a switch conductively coupled between the first conductive layer and the second conductive layer, the switch being wirelessly controllable to be in a conductive state or a blocking state.

An electronic door locking system of a motor vehicle is disclosed, comprising at least one receiver for the transmission signals of an electronic key, at least one control device for mechanically locking and unlocking at least one motor vehicle door, at least one contact element, accessible from outside the motor vehicle, for connecting an external voltage source, wherein the at least one control device for mechanically locking and unlocking at least one motor vehicle door and/or at least one additional control device has an emergency power supply algorithm, wherein the electronic door locking system is designed to detect an emergency power supply mode and to activate the emergency power supply algorithm, wherein the emergency power supply algorithm is designed to deactivate at least one function of a normal mode and/or, in the case of a function, to access previously defined data of deactivated components or to ignore said data.

A power control system for an electric vehicle without a start manipulator, and a method therefor, includes a communication device that performs wireless communication with an electronic key and a body controller connected with the communication device. The body controller determines a power control mode as a factory mode or an electronic key discharge mode based on whether an electronic key is learned and whether a battery of the electronic key is discharged and controls vehicle power transition depending on power transition logic matched to the determined power control mode.

Embodiments relate to enhanced access control features based on proximity between a portable electronic key and an electronic locking device. The portable electronic key receives first authentication information from an access administration device. Based on the portable electronic key being located within a threshold distance to the electronic locking device, the portable electronic key receives second authentication information from the access administration device. In some aspects, determining whether the key is located within the threshold distance to the electronic locking device comprises detecting a communication between the locking device and the portable electronic key. The portable electronic key may initiate an unlocking event at the electronic locking device based on the first authentication information and the second authentication information. Initiating the unlocking event comprises transmission of an access credential that causes the electronic locking device to permit access to an entry point.

It is provided a method for determining when to trigger positioning of a portable key device used in access control for an electronic lock controlling access to a restricted physical space. The method is performed in a positioning determiner and comprises the steps of: obtaining movement data from a motion sensor of the portable key device, the movement data indicating movement of the portable key device; determining when the movement data indicates a stop in motion of the key device; and triggering positioning of the portable key device when a stop in motion of the key device has been determined.

The invention relates to an authentication system (10) for a vehicle (100), in particular a motor vehicle (100), for storing an ID-transmitter (80) in the vehicle (100) with an outer housing (11) in which the ID-transmitter (80) can be stored. In this case it is provided that an electronic security unit is provided to monitor at least the secure storage of the ID-transmitter (80) within the outer housing (11).
