I real like the trailer lock but I have to say This is the 3rd lock I have bought and one of them the key position where you insert the key to the lock has been off like a little sideways so I cant insert the key and I tried to fix it but cant. And the funny thing about it I dont know how it happened or how I got the key out because you cant get the key out in that position.

This lock feels very solid and seems to be a huge upgrade to the previous locks we had purchased. It closes on all 4 different hitches we have. I am ordering 2 more.

The order process was simple and quick. Product arrive as per shipping request. I had looked at and tried several other lock over a period of several weeks from local stories but nothing came close to working. This lock fit on my 2005 Jayco hitch. This Fastway was the only one that was wide enough to fit the large flange on this hitch. It was easy to install and looks strong.


Comments
It has work great. Easy to use and still looks good.

great product..



- FA86-0015-312

Purchased 3 locks keyed alike, (also matched my Fastway adjustable hitch) Installed locks on two trailers, one coupler is a 2" and the other is a 2 5/16. Due to the coupler design the fit on the 2 5/16 the lock is pretty sloppy but it won't come off, I'll try to incorporate the safety chains under the loop and see if the helps. The third lock will be used by a family member, and since they're all keyed the same we can use each other's trailers. etrailer has always been great to deal with, as usual parts arrived on time.

Review from a similar Universal Coupler Lock in Trailer Coupler Locks


I think the Fastway Trailer Coupler lock is one of the best Toy Hauler locks on the market. It's a solid well constructed tough product, and reasonably priced...it gives you an extra edge of securing your Toy Hauler when your out of town at Car Shows/Cruis'ens and you can even reverse it on certain makes of trailers depending on how the trailer tongue/coupler is constructed/designed which makes the key slot even more difficult to get at. E-trailer is one of the best companies to do business that I have run across in a long time. There Customers Service Reps are excellent well trained individuals that have good customer service manners and follow ups...keep doing what you do best. Your on the same playing field as Summit Racing and a couple of other businesses that have excellent customer service reputations...

Review from a similar Universal Coupler Lock in Trailer Coupler Locks


Great hitch lock - haven't had a generator stolen yet with one of these deployed on the hitch. Downside is that the finish isn't Chrome - it's a mylar film that will peel off, and can cut you (personal experience)


Comments
Weve had no generators that have been secured with this tongue lock. Great hardware!!!

Review from a similar Universal Coupler Lock in Trailer Coupler Locks


very strong and sturdy BUT has two small problems the reason for not giving 4-5 stars they have to be removed and oiled every three months if you don't you will have hell of a time unlocking them, at first you think the key is not working and then you think that the lock has jammed to aid in this aggravation the lock will not release unless you keep key turned ( not spring loaded, they saved money by not adding this feature)(mistake)a a bit hard to hit hitch with hammer and keep key turned and not break key also tolerance is way to tight which of course leads to main reason for it seizing up. Fix the key and a little most tolerance or do not use it for long term storage. yes I kept the lock clean of dirt and debris.


Comments
it works great but would have liked some information on maintenance WD40 or 3in1 oil or Masterblaster and and where to put it in the lock or the pins that lock it had some problem with them locking up if they sat to long with out being opened or closed have five trailers 3 of them can set for months be for i use them BUT the good news nobody has even made an attempt to steal them like i said good stuff well built i trim trees for a living i get robbed more than the bank

Review from a similar Universal Coupler Lock in Trailer Coupler Locks


I think this is the best bang for you buck. Nice beefy lock. I was able to buy multiple locks for 3 trailers all keyed the same. It fits skinny or wide tongue configurations. Im in a cold winter climate, they will freeze up, but that is with any lock that you buy. Keep a little handy torch in the trailer to warm it up, takes only a minute. Ive had these for a little over a year with no problems.

A year later and nobody has stolen my trailers so... They work great

Review from a similar Universal Coupler Lock in Trailer Coupler Locks


The lock is well made but fits loosely in the 2 5/16” coupler. The “ball” part of the lock is too small for the space it occupies. I’ll probably modify it.


Comments
I’m still using the lock and it still works well. I’ve noticed most trailer campers use them when they unhook at campgrounds.

Review from a similar Universal Coupler Lock in Trailer Coupler Locks


I just received this lock and have used it only once on a small, folding-type trailer. But, from everything that I can see, it looks to be very well made. The key/lock assembly appears to work well and I can’t imagine that it would be easy to defeat. We have a larger, heavier trailer that we have yet to use it on. If my experience changes, I will update my review.

    If the Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers - Key 312, # FA86-0015-312, coupler is not snug, it may not be installed correctly.

  • Best Coupler Lock Recommendation for Atwood Yoke Coupler
    For the yoke style couplers my favorite coupler lock is the Fastway part # FA86-0015-312. We have found that this is the most universal of the locks we carry and also works the best.

  • What Type of Metal is Fastway Universal Coupler Lock # FA86-0015-312
    The Fastway Universal Coupler Lock # FA86-0015-312 that you referenced is made from hardened steel for the shackle and diecast steel for the housing and is designed to withstand most attacks. It would take some serious time to defeat this with a pry bar and sledgehammer. The sledge would also make quite a bit of noise which thieves generally try to avoid.

  • Is Fastway FA86-0015-315 Universal Trailer Coupler Lock Available Keyed to Key # 312
    You certainly can, just order 4 of part # FA86-0015-312, which will get you 4 of the Fastway Maximum Security Universal Trailer Coupler Locks keyed to key number 312. The lock is compatible with couplers for 1-7/8, 2 or 2-5/16 inch trailer balls. The # FA86-0015-315 lock you'd looked at is keyed to key number 315, so it wouldn't use your desired key.

  • Can Fastway Universal Coupler Locks Be Keyed the Same
    I confirmed with Fastway that yes, if you order multiple of these coupler locks with the same key code, they will be keyed the same. For example the Fastway Universal Coupler Lock # FA86-0015-306 uses Key 306 while the Fastway Universal Coupler Lock # FA86-0015-312 uses Key 312. As long as your ordering multiple coupler locks using the same numbered key you will be fine. I have have also included a review video for additional information on the coupler lock.

  • Replacement Key for Fastway Universal Coupler Lock with Key Code 312
    I'm not quite sure I'm understanding which part you're looking for a key for, but the # FA-KEY-312 you were looking at is designed to replace the key for a Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers - Key 312 # FA86-0015-312 with key number 312. If that's the part you're looking for, then you've found the correct key. If that's not what coupler lock you've got, let me know what you do have and I can see if there is a replacement key available for it.

  • Recommended Locks for 2-5/16-Inch Squeeze-Latch Type Trailer Coupler
    To secure your squeeze-latch type coupler such as # CTA-280 you can use a latch pin lock such as # 2847DAT, a coupler lock such as # FA86-0015-312 or choose a combination kit with both, such as the Master Lock # 3784DAT. Using this Master Lock kit will give your trailer dual protection from theft by securing both the latch mechanism and the coupler head.

  • What is the Height of Fastway Coupler Lock DT25013KA
    The Fastway # FA86-0015-317, # FA86-0015-312 and the # DT25013KA are all the same locks and will be the same size. The reason for the different part numbers are that the # FA86-0015-317 and FA86-0015-312 are locks that can be ordered keyed alike a similar Fastway lock (key numbers 312 and 317), where the # DT25013KA comes with a randomly assigned key/lock combo. The # DT25013KA is a great choice if you don't already have a Fastway lock that you're trying to match.

  • What is the Difference Between Fastway Coupler Locks DT25013KA, FA86-0015-312, and FA86-0015-317
    Basically the three part numbers you mentioned give you the same lock but the different part numbers allow you different options for the key. The part # DT25013KA gives you the lock with a random key number. If you order the part # FA86-0015-312 you get the key number 312, or the part # FA86-0015-317 you get the key number 317. So if you are looking to order a few with the same key you pick one of the two previously mentioned. The part # e98882 can not be keyed to the Fastway locks...
