According to some embodiments of the invention, the systems and methods include a smart lock that provides redundant access control. The smart lock includes a button that has a plurality of redundant access channels for receiving authentication information. The redundant access channels may include a biometric scanner for receiving biometric information, a passcode keypad for entering a token, or a wireless transceiver for receiving a token from a mobile device and transmitting a response to the mobile device. When the user cannot open the lock through the first redundant access channel, the smart lock is configured to allow access through a second access channel. In some embodiments, the button is a freely rotating button that translates the rotational energy into electrical energy using, for example piezo elements, to energize a rechargeable power source, such as a capacitor bank. ## Claims ### Claim 1 A lock comprising: a bolt; a hardware processor configured to receive and validate authentication information; a button configured to unlock the bolt in response to the hardware processor validating the authentication information; a rechargeable power source coupled to the hardware processor, wherein the button is a freely rotating button configured to energize the rechargeable power source when the button is rotated, and wherein the rotational energy generated by the movement of the button is converted to electric energy and stored in the rechargeable power source. ### Claim 2 (depends on 1) A system comprising: the lock according to claim 1; a user device configured to request access to the lock and communicate with the hardware processor; an administrator device for controlling access to the lock, the administrator device being configured to grant or deny the request for access by providing the user device valid authentication information; and wherein the lock comprises a storage medium for storing access information. ### Claim 3 (depends on 2) The system of claim 2, wherein the lock is configured to transmit a response. ### Claim 4 (depends on 2) The system of claim 2, wherein the administrator device is configured to grant access to the user device based on a set of rules. ### Claim 5 (depends on 4) The system of claim 4, wherein the set of rules comprises a user role that is associated with a set of permissions to one or more locks. ### Claim 6 (depends on 4) The system of claim 4, wherein the set of rules further comprise a triggering event. ### Claim 7 (depends on 1) The lock of claim 1, further comprising a piezo element, wherein the rotational movement of the button is applied to the piezo element and generates piezoelectricity that is stored in the rechargeable power source. ### Claim 8 (depends on 1) The lock of claim 1, further comprising an armature and electrical generator, wherein the rotational movement of the button is applied to the armature and electrical generator to generate electrostatic energy that is stored in the rechargeable power source. ### Claim 9 A method for providing access to a lock having a rechargeable power source coupled to a freely rotating button configured to energize the rechargeable power source when the button is rotated, the method comprising the steps of: providing user authentication information to the lock; receiving a response from the lock regarding whether the user's authentication information was validated; rotating the freely rotating button; converting the rotational energy generated by the movement of the freely rotating button into electric energy; and storing the electric energy in the rechargeable power source. ### Claim 10 (depends on 9) The method of claim 9, wherein the step of providing user authentication information further comprises one of: sending a request from a device of the user; receiving a token at the device of the user; and providing the token to the lock. ### Claim 11 (depends on 10) The method of claim 10, wherein the step of sending a request from the user device comprises one of: sending a message to an administrator; placing a call to an administrator; and sending a notification to an application on an administrator's device over an network connection. ### Claim 12 (depends on 11) The method of claim 11, further comprising the step of prompting the user for additional authentication information. ### Claim 13 (depends on 10) The method of claim 10, wherein the token is a dynamic passcode; and wherein the step of providing the token to the lock comprises transmitting the token to the wireless transceiver of the lock. ### Claim 14 (depends on 10) The method of claim 10, further comprising receiving a response from the lock at the user device. ### Claim 15 (depends on 9) The method of claim 9, further comprising the step of automatically notifying an administrator when the user attempts to access the lock. ### Claim 16 (depends on 10) The method of claim 10, wherein the user device automatically receives the token. ### Claim 17 (depends on 16) The method of claim 16, further comprising the steps of: registering the triggering event; identifying the lock; sending a request for access to the lock; determining whether the user has rights to access the lock based on a set of rules determined by an administrator; and receiving the token based upon determining that the user has access to the lock. ### Claim 18 (depends on 17) The method of claim 17, wherein the triggering event is based on distance to the lock. ### Claim 19 (depends on 17) The method of claim 17, wherein the triggering event is based on a gesture. ### Claim 20 (depends on 9) The method of claim 9, further comprising the step of requesting activation of an inter-connected hub of devices.
