Proven Locks' specialty lock collection addresses the security gaps that standard coupler and padlock setups leave open — spare tires, propane tanks, cargo doors, and ancillary trailer equipment that most trailers carry but few owners think to lock. Every trailer accessory that can be unbolted or detached while you're not looking is a theft opportunity, and this collection is built specifically for the non-standard lock points a basic trailer security kit doesn't cover.
Spare tire theft and propane tank removal are two of the fastest-growing forms of trailer theft — both take under two minutes with no specialized tools. These accessories your trailer can't operate without are often left completely unprotected.
- Spare tire lock to secure mounted trailer spares
- Propane lock to prevent unauthorized tank removal
- Cargo lock options for specialized door and hatch types
- American-made construction
- Free same-day shipping

Browse specialty locks by application — spare tire, propane, cargo — and close the security gaps your standard coupler lock doesn't cover.
