AMPLock - U-BRP2516 Heavy Duty Trailer Coupler Lock, 2 5/16" RV & Trailer Lock, Ball Coupler with Straight Lip, Anti-Theft RV Locks & Trailer Protection with Push and Lock System, Ideal Trailer Locks

So I'd like to do a pretty comprehensive review of this lock because I had quite an experience with multiple locks of theirs and their customer service representative.First, I'll go through the features ratings that I did on the lock.Easy to Install: Yes, very simple and easy. Comes with two keys plus a lock key tag that has specific numbers on it that you can use to order either extra keys or extra locks that match existing locks and keys.Easy to Use: Yes very easy to use. I don't see how you could not figure it out.Security features: I gave this 4 stars, and this is tied into a rather complex story that I'll get into shortly.Service: Impeccable. Customer service representative went above and beyond to solve my issue, so much as to take my request to the design team of engineers and fix the problem at the source, and re-manufacture the part to work better.Quality: Top notch quality. Super heavy duty. You would need to break or severely bend the trailer coupler before this lock ever came off.The Story: So last April, I bought one of the locks for my trailer. When taking it out. I looked it over carefully and just admired the most expensive lock I'd ever bought. On the steel ball part of the lock (which also contains the key and locking mechanism), I noticed that the locking pin that catches on the other part of the lock had some play in it. I didn't think too much about it initially and used it for a few months, but over time, it seemed to have more play in it than I remembered. I e mailed the Amplock representative after explaining the situation and sending a hand drawn diagram of the problem I was having, they sent me another lock. When I got this lock in, the new one also had a good amount of play in it, not quite as much as the old one, but enough to make me wonder why it was there and if my old one had originally had that much and gotten worse over time. I explained that situation to the representative and they eventually got back to me and said they would be addressing the issue with the design team and would be manufacturing an updated model to the lock I got that would fix the issue. It took a little over a month, but I got my new lock in. It was much better. There was still a very small amount of play in the locking pin, but far better than the last two they had sent and enough to look like it was going to be a very good long term lock.Maintenance: In order to service the lock, Amplock recommends silicone free PL-100 lubricant. I've read reviews before complaining of seized up locks from improper care and not using the proper lubricant. Despite the 5 star review on Amplock locks and their service, I feel they could improve slightly by including their recommended lubricant in their literature and Amazon listing. Heck, for $265, I think it wouldn't be a bad idea for them to include a little mini spray can of their recommended lubricant, just so people can get started off on the right foot using it and so they'll know exactly what to use.Other than that though, Amplock has really got a good product, and their customer service is very helpful and they stand behind their product. I've heard people review this item saying "this is the lock you buy after your trailer gets stolen" and I quickly realized that the current lock I had on mine was a very minor deterrent, and I run a landscaping business out of my trailer, so I wasn't going to chance it.

First let me say I've tried a lot of different trailer hitch locks and there's a lot of useless garbage out there that can be defeated with nothing more than a 3 lb sledge hammer. They're inexpensive for a reason, they're CHEAP junk! The AMPLOCK U-BRP2516 RV/Trailer Coupler Lock is not cheap in any aspect.This AMPLOCK U-BRP2516 RV/Trailer Coupler Lock is by far the most robust and nicest of any trailer hitch lock I've ever tried. The shear weight of the device (~12 lbs) lets you know that if someone wants to try and remove it you can bet they'll have their work cut out for them. They may eventually get it off, but they'll have invested a lot of time and sweat in doing so. I'm sure the noise they'll have made in trying to get it off will have alerted you, or someone else, to the fact that something is going on.It is expensive, but I look at it as the price of the insurance deductible (~$265) if the trailer was to be stolen, minus the hassle associated with having to deal with replacement of all of the ancillary gear that was in the trailer. I purchased an extra set of keys ($25 for 2 keys), it comes with 2-keys, after I received the device because you ARE NOT going to go down the local ACE hardware store and have a spare made. They are custom keys that are designed and manufactured by AMPLOCK for the lock mechanism. If you lose the key identifier tag that comes with the original keys you are going to be up the "proverbial" creek without a paddle because you need BOTH key code and key identifier number to get spares from AMPLOCK. Save yourself the pain and buy a couple spare keys!

Superman would have a hard time bending this lock. And I love that the keys are all heavy duty and unique to each lock. Keys comes with an engraved serial number plate, in case you may need to order new ones.Just look how thick the lock is with my fingers on it. Its 100% solid.We love our beautiful motorcycle/cargo trailer.. So we wanted a LOCK that lets us rest easier while on vacations, or even when it's just sitting in the driveway at home. The lock is super HEAVY (easily 10 pounds).Yes, it's a bit expensive, but it's the Real Deal!Nobody is hammering it off, torching it or breaking it. Plus, if you have a large heavy trailer, they won't even try to hook up chains and drag it away with this lock on it, because your trailer will be smashing the back of their vehicle bad..After you see and feel the lock next to all the everyday so-called good locks, there is no comparison.

Amazingly strong! Cannot remove with the key. If key is lost, company is quick to respond with a replacement.

Purchased to secure high value trailer. This lock is a great deterrent.

Looks and feels very strong and secure worth the price to keep your rv or trailers secure
