Review on 🔒 TowWorks 5/8" Trailer Hitch Locking Pin Set - Keyed Alike, Adjustable Ball Mounts, Double Safety, Anti-Rattle - Fits Class III - V Hitches - 79852 by Bill Tripi

This went well with my lead but before using it for a proper trip I somehow managed to damage the round key. Something pressed on the key and it became slightly out of round and would no longer open the lock. This can be very bad if it happens on a trip where you don't have access to a second key. This style key doesn't really offer any extra security, quite the opposite, so it's no good having a key that can be easily damaged.
