Why risk a lockout due to a lost key? STRATTEC’s BOLT Receiver locks work with your vehicle key. Users simply select a GM, Ford, or Chrysler compatible lock, insert and turn their vehicle key, and the lock will be permanently coded to their key. BOLT Receiver locks come in ½” and 5/8” sizes with a weather-resistant lock shutter, automotive-grade, 6-tumbler lock cylinder, and thousands of unique key-codes for extra security. They are now upgraded with longer pins to accommodate Class V hitches.The user need not carry extra keys, remember a combination, or thumb through an endless ring of keys searching for the right one.
