Abstract: A resettable axial pin tumbler lock having a spindle rotatably mounted in a barrel with the spindle and barrel forming a "lock" radial interface and a plurality of cooperating axial wells for receiving axial pins. A plurality of driver pins are disposed in the wells in the barrel and spring biased across the "lock" interface into the wells of the spindle to lock the spindle against rotation in the barrel. A reset ring is rotatably mounted in the barrel with the reset ring and the spindle forming a "reset" radial interface and a plurality of cooperating axial wells for receiving axial pins. A plurality of reset pins are disposed in the wells in the spindle and reset ring in axial alignment and engagement with the driver pins so that the spring bias on the driver pins also applies a biasing force to the reset pins.
