I bought this lock in November after our second trailer had been stolen (they cut thru the padlocks). At that time our trailer was buried in snow and ice and we couldnt see the wheels much less put this lock on a wheel. We got a melt in early March, I handed it to my husband to put it on the trailer and he came back in and said "where are the keys?" There were no keys to this thing. I would expect the keys would have been taped to the lock but they werent. I contacted the company with several emails to get a set of keys but they NEVER RESPONDED. So all we got is a very expensive door stop. PFFFFFFT. Lousy company who deserves to go belly up in this economy because they dont care about their customer.
