Abstract

An electronic lock includes a compression spring that stores energy to ensure that the electronic lock re-locked after unlocking. The spring is received between a lock bolt and a lock bolt housing. When the electronic lock is locked, the lock bolt is received in a notch of a locking portion. When the electronic lock is unlocked, a motor moves both the lock bolt and the lock bolt housing in a direction to remove the lock bolt from the notch. After a predetermined amount of time, the motor is reversed to move the lock bolt housing in an opposing direction. If the outside handle has not been released, the lock bolt does not re-enter the notch. The spring is compressed between the lock bolt housing and the lock bolt and stores energy. When the outside handle is released and the notch returns to the original position, and the spring pushes the lock bolt into the notch to ensure the electronic lock is re-locked.
