System and techniques for a secure wireless lock-actuation exchange are described herein. After receiving a request to actuate a lock from a device, a controller can calculate a challenge counter and then perform verification iterations until an end condition is met—which is a failure of a verification iterations or the number of iterations reaches the challenge count. If the verification iterations reach the challenge count (e.g., there are no failed iterations), then the controller actuates the lock. Each iteration includes an exchange between the device and the controller that the device validates by signing a message with a private key shared by the device and the controller. The exchange also includes a freshness value integrated into the device validation to prevent replay attacks.

Remote control for actuating garage doors and other barriers, and method and system of using same. A base unit includes: a wireless receiver, to wirelessly receive from an electronic device an incoming wireless signal indicating a command to actuate a garage door; a wireless signal constructor, to dynamically construct an outgoing wireless signal which comprises a rolling code; a wireless transmitter, to transmit the outgoing wireless signal to a wireless receiver of a motor unit that is operably associated with the garage door. A wireless signal constructor dynamically constructs the outgoing wireless signal without having access to a secret seed value that is accessible to the motor unit. A local storage unit stores a data-set of rolling codes that are associated with the motor unit; and the outgoing wireless signal is dynamically constructed based on a next-available rolling code obtained from the local storage unit of the base unit.

The present invention relates generally a system and method for providing rolling code remote device functions to provide keyless entry to multiple makes and models of cars. The present invention is adapted to produce the radio signal type and transmitted data of an original manufacturer's keyless entry remote device system by implementing multiple modulation schema and data encoding techniques.

The present invention generally relates to the field of replicating or copying keys. More specifically, the present invention relates to creating a copy of a master key based on a captured image of the master key. The present invention identifies a set of target key information based on vehicle and or lock information as well as the image of the master key to provide for the cutting of a duplicate key blade copy to be delivered to a user or to another location. Additional key information may also be captured along with the image of the master key.

A method for controlling access to a restricted resource is provided. The method may include receiving, by a cloud server, an identifier from a user device over a long range wireless channel Further, the method may include comparing the identifier with a plurality of identifiers registered with an access control device. Further, the method may include authenticating the user device based on the comparing and subsequently transmitting a code to the user device upon successful authenticating. Thereafter, the user device may transmit the code to the access control device over a short range wireless channel. Further, the access control device may be configured to provide access to the restricted resource based on receiving of the code. Further, the method may include transmitting the code to the access control device over a long range wireless channel so that the access control device may authenticate the user device.
