This worked great a number of times where I had to leave the trailer unattended. Easy to install and easy to take off.



by:

Tire developed a minor leak in the sidewall from the molding stamp on the side that appears to have been excessively deep. This occurred just after the one-year warrantee, so I am stuck with a manufacture defective tire and no warrantee.



by:

Has worked well to keep trailer secure, but pitted and rusted, even with FluidFilm treatment. But thats expected in Florida.



by:

yes i have bought alot from etrailer and this lock i did have 3, great lock, so i needed another so no doudt what i was getting, so i placed the order , now this is y its a 4 star, so much time had passed since i placed the order and not a call or message from etrailer that it was on back order, at that point when i called them they offered me another type of lock , very nice of them but i wanted all my locks the same, my wife says im OCD but im not i just retired from Army and everything has to look sharp and my home and property does just that , i started getting updates on my order after i place the first call, u can look at that several ways but i see it as , it is what it is, things happen , the only thing i say is this, the keys are made with super soft material so keep them lubed cause i didnt and broke a key off inside lock, but now i have my can of lube there with all my trailers to keep them in easy working order

still awesome, a few s of oil and wipe clean and works like new, I wont be without this lock unless they stop making them



by:

I own 4 trailers and have had many locks, i ran across this lock and bought one, i was excited that its the one, so i bought another , then last week my big trailer was loaned out and had such a hard time getting the old lock off and i keep them lubed but after sitting for 3 months under the barn it still locked up and had to ply it off while holding the key, so that same night i pulled up etrailer and ordered 2 more and upon getting them i right away changed them out, great lock, for myself great lock, yea there r better ones out there ive seen i guess, i wont ever know if they r better cause ill NEVER
paid that kind of money for one, these r great and i live out and they know what they will get if trying to steal my trailer, i honestly beleive i can give my word that these r awesome locks , hope u will try one, and etrailer has always got my order out fast, great company

product is best , have them on all my trailers , and i must say if u could make the key stronger than u should never need another lock , the key is awful , it will bend, or break but if u take alittle time , like 10 seconds ever so often and 3-4 s of oil on the key and into lock and work it around u will never have a problem, thats just what i do but other just want to be negative, and say key broke, yes i bet it did if ur thinking it nevers needs alittle WD40



by:

Stored the boat trailer only on a friends acreage…he was concerned about theft…researched other locks and then found this one…success!!! Just picked up the trailer the other day….all good!!!!



by:

Jessie at etrailer suggested this product and was also very helpful with a return.
This towsmart is heavy and fits my 1 7/8 tongue very well. The key slot position is good. Only improvement would be a dust cover for the key cylinder.



by:

Adjustable lock fit well and snugged up tightly on my trailer hitch coupler. This is very good for couplers that do not have a lip on them which most other coupler locks clamp on to the lip. Locking mechanism is easy to use. The red color on the large top portion I think helps thieves think twice before even approaching the trailer since it looks like it would be a lot of hard work to remove to steal the trailer. Great product.



by:

Bought this for my rv trailer and it would not fit securely no matter how it was installed it would simply slip out of the hitch. I tried it on 2 other trailers with the same result.



by:

I use them everyday, they are great loc ks.



by:

It is early on with this, I'll see how it does during the winter. It does fit loosely but you are unable to remove it,so it should keep the trailer more secure.



by:

Good quality; heavy duty. Good design--universal as advertised.



by:

I like the product. Exactly as described. Fantastic service from etrailer as usual.
Molly and the gang are great? will continue to do business with them.



by:

Key broke off in lock. Weak metal in key. Not very happy.



by:

I like how good this works its easy to use and works great
