BOLT®, the innovators of Breakthrough One-Key Lock Technology, knows the best way to prevent trailer theft is with a visible and functional sign of security. To meet this need, the company is introducing its Off-Vehicle Coupler Lock that secures a trailer when it’s not attached to a vehicle.

The Off-Vehicle Coupler Lock is a new dimension in trailer security that features BOLT’s patented one-key lock technology that permanently programs locks to the vehicle’s ignition key for single-key use no matter how many BOLT locks are being used.

The lock is easily programmed the first time the ignition key is inserted into the BOLT Lock cylinder through the use of spring-loaded plate tumblers that move up and down to code the cylinder to that specific key uniquely.

Made of hardened steel for extra security, the Off-Vehicle Coupler Lock works with 1-7/8”, 2”, and 2-15/16” couplers to keep a variety of trailers secure while unattended. The innovative BOLT lock is a visible theft deterrent that is designed with a unique plate-tumbler sidebar to prevent picking and bumping.

A highly durable powder-coated finish is factory applied to the lock to keep dirt and moisture out while protecting the locking mechanism from harsh weather.
