Systems and methods for providing redundant access control systems with removable wireless buttons are disclosed. According to some embodiments of the invention, the systems and methods include a smart lock with a button that is enabled to communicate to a network device, a central access server, or an administrator device. When a user requests access to the lock, the removable wireless button communicates the request to the network device, administrator device, or central access server. The removable wireless button is configured to communicate directly to the central access server and the administrator device, or indirectly through a network device. The button may be detached from the cylinder and docked onto a recharge station. In some embodiments, the removable wireless button includes an inertial module motion sensor that determines whether a door is open or closed.
