The VIDEO SHOWS THE BOLT Padlock 2.0, a New and Improved padlock.
This is a new lock cylinder of high quality components manufactured by Bolt Locks, part of Strattec. These locks are also available in padlock form and the video below shows how those operate. The locks shown above operate in the same way.
Once the ignition key is inserted and twisted, the lock remembers only that key and then you can use your ignition key for all the locks on the service/utility body. Think how great it will be to only need to use that one key for your truck and all the doors on the service body! No more fumbling for the right keys.
