Jaycar Alarmed Trailer Lock – Cast Stainless Steel with 120dB Tamper Siren

Your caravan's been sitting in the yard for a few days and you've already checked the hitch twice. This one kills that worry before it becomes a Tuesday-morning heart attack.

The frame is heavily built cast stainless steel with a security crossbar that shrugs off drilling and angle-grinder attempts. On top of that, a tamper alarm fires a +120dB siren the second someone's fiddling with it. The siren electronics are water-resistant, so a wet night at the caravan park won't silence your backup.

You get a CR123A long-life battery in the box (spares available) and three security keys. Works with or without a dummy towball, and fits non-towball hitches including DO35 and Treg couplings. If you've got a jet ski, a small trailer, or a caravan that isn't coming home tonight – this is the lock you want on it.
