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. To unlock the lock, a service key engages the reset pins and axially displaces both the reset pins and the driver pins against the spring bias to align the radial interfaces between the two sets of pins with the “lock”interface. To reset the lock, a reset key engages the reset pin and axially displaces both sets of pins to align the radial interfaces between the pins with the “reset”interface to permit rotation of the reset ring relative to the spindle while locking the spindle to the barrel. The reset pins have different axial lengths so that rotation of the reset ring relative to the spindle and drive pins changes the combination of axial pin displacements required to align the pin interfaces with the “lock”interface. A detent mechanism is provided between the reset ring and the spindle to indicate when the reset ring is in a position where its axial pin wells are in alignment with the pin wells in the spindle and the barrel.
