Don't bother with this lock. I noticed my trailer gone and this lock laying on the ground in two pieces. Apparently they shoved a prybar between the chrome U-bar and snapped it. I doubt the lock slow down a thief for more than 5 seconds.

The security on these things is a joke. I lost the yellow part to one of these, so I bought a new one. My old key works in the new one. Is that a coincidence?

So the only chance you have is against somebody that doesn't know this... Well now everybody knows this.

Anyone looking for a spare key for these locks can get them free at 1-800-234-6992 ext. 4 (Kim Schmit). They will send you two keys free all you need is a key number that is on the keys.

The "key" if you want to call it that is a total joke. They almost all have the same keys and at that its a very easy lock to pick. Also the pin (I believe its technical name is a "locking dog") that holds the shackle from sliding out does not protrude much which makes it possible to, without much force, force the lock open. It appears to be heavy strong steel and might be somewhat hard to cut but very easy to pick or force open. I would try another lock.

I sell cargo/utility trailers and everytime a customer comes in to purchase a new trailer because their old on was stolen even with a lock on the front i ask the "was it the yellow one with a u-bolt on top?" they say "yes how did you know?" That lock is the easiest to cut off. a cordless grinder takes about 10 sec. to cut the u-bolt and it drops. Check out the Fulton Gorilla Guard. It is the most secure lock that we know of.

This will not stop a thief. Easy to pick or shim, easy to break, all the keys are the same with a single notch. I'm returning it.

I lost the keys to mine, so I grabbed a cordless drill and a 5/16" bit. Within literally 2 effortless seconds the lock fell off. The metal is comically soft.

Will not be purchasing another!

I bought this unit at a local "Wally-World" for 25 bucks. Only had it a couple weeks. I know it's not the best, but I just thought it would at least slow someone down to the point that they would not be able to run off with my camper before drawing a lot of attention. So I went to hook up my camper for a trip, and as I unlocked this thing, THE TUMBLER CAME OUT! Lot o' good that is!
That said, I found a MUCH better unit- just a shame Amazon does not carry this one:

Sure, it's a good bit more. But as they say- you get what you pay for!
