BOLT Trailer Spare Tire Locks are available from STRATTEC Security Corporation to fit steel rim wheels to a studded mount.

Featuring patented Breakthrough One-Key Lock Technology, the Trailer Spare Tire Locks are designed to permanently program to a vehicle's particular ignition key and eliminate the need for multiple keys.

The locks, which don't come equipped with their own key, are programmed during the first use: When drivers insert their ignition key into the padlock cylinder, spring-loaded plate tumblers move up and down until they are matched exactly to that key. The first time the key is rotated, the cylinder is uniquely coded to that key. When the key is removed, the cylinder moves into the locked position. When the key is turned again, it will rotate to the unlocked position.

BOLT Trailer Spare Tire Locks are manufactured with an electroless nickel-plated carbon steel pin or shaft assembly/shield for strength and durability. They feature an automotive-grade stainless steel lock shutter to keep out weather and debris and a six-plate tumbler sidebar that prevents picking and bumping.

The Trailer Spare Tire Locks work with most General Motors, Ford and Chrysler/Jeep vehicles on the road today. Additional locks such as padlocks, receiver locks and cable locks are also available.
