Abstract
Locks and keys are disclosed with electromagnetic as well as mechanical actuation. Several forms of reverse sidebar are described, avoiding binding of the lock release mechanism by premature turning of the key by a user. An embodiment of a system is described wherein the lock units are in radio communication with a control console, for setting access parameters and monitoring accessing events at each of the various locks.
