BOLT Receiver Locks
STRATTEC Security Corporation offers BOLT Receiver Locks for Class I through Class V hitches. BOLT Receiver Locks feature the company’s patented one-key lock technology that is designed to permanently program the lock to the specific vehicle’s ignition key, eliminating the need for multiple keys. When drivers insert their ignition key into the lock cylinder, spring-loaded plate tumblers move up and down until they are matched exactly to that key. The Receiver Lock features an automotive-grade lock shutter to keep out debris, as well as a six-plate tumbler sidebar that prevents picking and bumping.
