Abstract
Provided is a key lock operable for locking and unlocking a latch control mechanism. The key lock includes a key collar with a front face, an outer cylindrical surface, and a longitudinally extending key slot. A center collar is concentrically disposed about the key collar such that an inner cylindrical surface of the center collar is fit to and rotatable on the outer cylindrical surface of the key collar. A series of cylindrical rotating pins are disposed in the center collar, each rotating pin having a notch with a key ID surface configured to engage one of a corresponding series of ID cut surfaces of a key when the key is inserted in the key slot and rotated to a key verification position, thereby rotationally orienting each pin at a respective ID position.
