Altor's Blog
After a lot of research, I settled on an ICON hitch lock for my new trailer. Other locks out there carrying 5-star reviews that are cheaper, and there is no lock that cannot be defeated. That said, this lock is a brute and will take a significant amount of time to defeat, I don't care what you throw at it. The other locks that I saw, with 5-star ratings only took minutes to defeat with a simple crowbar when you dug deeper. If you have a trailer that is worth some money, this is the lock you need/want. Spend the extra bucks for the peace of mind this lock will provide.
If you're not sure the lock will fit your coupler - just call them!
I discovered Altor locks after watching the LockPickingLawyer on Youtube. I am very pleased with all 25 pounds of it! The customer service is outstanding. If I get another trailer, then I'll buy another Altor lock.
This is very heavy duty as described, it would probably be easier to cut then weld a new tongue on instead of trying to remove the "ICON"
