Lock Noob got his hands on the NPX-002 from Works by Design and wanted to put its security claims to the test to see how well they held up. The lock’s designers created this travelling key system, in which the key’s bow spins some internal gears and the actual key blade moves into place deep inside the cylinder. The key only fits perfectly in the exact position, at which point the keyway seals off, leaving no place for your standard picks or tension tools to reach the pins. To prevent the normal impressioning techniques, the brass ones had a plastic pin inserted.
