Bolt locks for diesel trucks are auto-memorizing lock systems for diesel vehicles and vehicle security needs. Instead of carrying around a separate key for your toolbox, trunk storage, hood, ignition, and more, simply carry one key! Bolt locks instantly and permanently memorize your ignition key’s unique cut lines. By adding a Bolt padlock, receiver lock, cable lock, or any other Bolt product to your truck, you can access all areas with a single key. This eliminates the need for multiple keys for the same truck, and also lessens the likelihood that you’ll lose an important key. Browse our Bolt diesel locks for Dodge, Ford, and Chevy above.
