STRATTEC Security Corporation has introduced its upgraded Padlock 2.0 featuring BOLT Breakthrough One-Key Lock Technology. BOLT’s Padlock 2.0 features a spring-loaded, chrome-plated 5/16-inch diameter hardened steel shackle inside a crush-resistant body shell. The Padlock 2.0 also includes an automotive-grade, stainless steel lock shutter that keeps out weather and debris. Designed for commercial and industrial applications, it features improved performance thanks to its double ball-bearing locking mechanism. The Padlock 2.0 also includes a six-plate tumbler sidebar that prevents picking and bumping. Breakthrough One-Key Lock Technology eliminates the need to carry extra keys or memorize combinations because the padlocks can be permanently programmed to lock and unlock using the vehicle’s ignition key. When drivers insert their ignition key into the padlock cylinder, spring-loaded plate tumblers move up and down until they are matched exactly to that key. The first time the key is rotated, the cylinder is uniquely coded to that key. When the key is removed, the cylinder moves into the locked position. When the key is turned again, it will rotate to the unlocked position. The BOLT Padlock 2.0 works with most GM, Ford and Dodge vehicles.
