Review on 🔒 Master Lock Trailer Lock Combo, Coupler & Receiver Lock Pack, 3794DAT, Red by Tony Weber

I bought this set because I liked the idea that one key opens everything. Received January 2019, hitch lock fitted and the hitch lock when I got it didn't put the receiver lock on until May because I wasn't towing at the time and the ball mount was in the garage. Started towing in May and used all three locks until the end of October when the boat went into storage (locked) and I removed the ball joint but left the receiver lock on thinking it would be right where I found her could. this spring. Today I wanted to insert the ball joint but couldn't unlock the receiver lock. I thought I had the wrong key so I tried the clutch lock - it worked fine. Tried the clutch lock - a little hard to turn but it also opened so the right key was there. tried graphite lube, then penetrating liquid, then extended the spray for 2 hours - didn't budge. Apparently he got a little angry and broke the key in the lock. I thought it would be difficult to cut it now, but pulled out a saber saw and cut it in under 30 seconds. So much for safety. I saw another review where they just hit it with a hammer. So if it doesn't cut through like aluminum, I could probably hit it with a hammer. I'm not so sure about the rest of the set now. Be sure to lubricate the hitch locking pawl before it freezes.
