How to secure both the tow-vehicle receiver and the parked trailer coupler
Receiver locks and coupler locks protect different points in the towing system.
A receiver lock replaces the standard pin and must match the hole diameter and usable span.
Protect the receiver connection
A parked trailer needs a coupler lock that prevents a thief from connecting a ball or bypassing the latch.
Protect the parked coupler
Loose universal locks can leave space for prying, while overly tight locks may not seat fully.
Maintain weather-exposed cylinders
Locks deter and delay theft but should be combined with wheel security, lighting and documentation.
