BOLT Thumb Turn Lock hi-res

For maximum user convenience, UnderCover(tm) Elite, UnderCover Elite XL and Extang(TM) EnCore tonneau covers now feature innovative  BOLT(r) one-key lock technology  in a new, ergonomically-friendly latch.

BOLT’s unique, patented one-key lock technology permanently programs the locks on these tonneau covers to the truck’s ignition key so that just a single key is needed, no matter how many BOLT locks are in use. The first time the key is inserted into the BOLT lock cylinder, spring-loaded plate tumblers move, immediately coding the cylinder to that unique key.

BOLT Locks are available for many Ford, RAM, Toyota, Nissan and General Motors light truck models, including the new GM center-cut, high-security keys for late model pickups. In addition to securing the contents stored under a tonneau cover, weatherproof BOLT locks are available to protect a range of other equipment and gear. BOLT products include a chrome-plated, hardened steel two-inch Padlock, durable stainless steel 5/8-inch and 1/2-inch Receiver Locks, a Coupler Pin Lock, a six-foot vinyl-coated Cable Lock, a GM Tailgate Handle Lock and a Toolbox Latch Retrofit Lock.

“We look for innovative ideas that will benefit our customers as we continue to expand and improve our tonneau covers and BOLT offers the latest technology in the industry to give our customers added accessibility and ease of use,” said Jason Hutchens, UnderCover marketing director.

BOLT Locks are available through a network of major retailers and from the BOLT website and come with a limited lifetime warranty. For more information, visit
