I always trusted the Reese name for 30+ years, nothing but Reesee for me, but this #74172 hitch pin has changed my thinking. I had this pin a little over 3 years. Being a contractor, I change my hitch attachements 3 to 4 times a week, and after the first year of use I noticed that you could open this lock with any key of similar size no matter what brand. Now after 3 years, I can open it with a pocket knife blade. It becomes more and more useless as it ages. I would never trust this lock with valuables hitched, and now I only use it to move things around my construction yard. STAY AWAY from this false security.
