A lock for providing redundant channels of access comprising: a hardware processor; a power source; a cylinder adaptable to fit a standard profile slot of a door, the cylinder comprising a cam to engage a bolt; a button for engaging the cam to unlock the bolt and for forming a rose knob for protecting and concealing the hardware processor, the power source, and the cylinder; and a rose protector for protecting and concealing the hardware processor, the power source, and the cylinder, such that the hardware processor, the power source, and the cylinder are entirely protected and concealed by the rose knob and the rose protector, wherein the rose protector has an outer wall and an inner wall forming an annular groove for interlocking with the rose knob, the inner wall formed substantially perpendicular with respect to the door, the outer wall formed conically with respect to the door, the annular groove having a graduating thickness that decreases along a plane normal to the door as a result of the conical shape of the outer wall, wherein the shape of the outer wall deflects a strike of brute force, wherein the rose knob has an exterior surface and an interior surface the exterior surface and interior surface forming: 1) an annular rim for interlocking with the annular groove of the rose protector, the annular rim having a thickness that matches the graduating thickness of the annular groove; and 2) an opening comprising the power source, the hardware processor, and a plurality of redundant access channels for receiving authentication information, the redundant access channels comprising a biometric scanner for receiving biometric information, a passcode keypad, and a wireless transceiver configured to communicate in near real-time with a mobile device, wherein the rose protector has a set of through-holes for one or more securing rods and one or more fasteners that secure the rose protector to the door, and when the annular rim of the rose knob slidably interlocks with the annular groove of the rose protector, the rose knob is irremovably secured to the rose protector, wherein the rose knob is freely rotatable until valid authentication information is received from the passcode keypad, biometric scanner, or mobile device, upon which the rose knob is configured to actuate the cam to unlock the bolt, and wherein the hardware processor is configured to validate authentication information received from the passcode keypad, biometric scanner, or mobile device based on a set of rules determined by an administrator, unlock the bolt when a user is authenticated through a first channel of the plurality of redundant access channels, and when the user cannot open the lock through the first channel, allow access through a second channel of the plurality of redundant access channels. a hardware processor;
