by:

These trailer coupler locks are great, easy to install and easy to take off. More than pleased the product and the shipping! Thanks guys, keep up the good work!



by:

Seems sturdy. Unfortunately Fastway is one of those companies that thinks it is necessary to collect marketing information for you to complete warranty registration. Minus 1 star for that.



by:

Ball not as big as it should be and had to shim it. Tricky to get it tight enough to stay on my trailer hitch. Very heavy duty and seems to do the job.



by:

I was able to break this off my hitch with a hammer because the key hole kept freezing up. Your product almost made me late to an event. So I ordered a replacement to see how this one works out. This order too way longer than expected to be delivered. I doubt I will be ordering again.

That is one rough way to break the lock off. If the lock is freezing up on you we recommend using a silicone-based lubricant spray like part # RM-747 to help loosen things up. Stay away from using WD-40 and it will muck up the lock internally. If the spray does not work be itself then what you can do is use the spray, then the key and lightly tap the back of the key to make sure it is fully seated in the lock before turning.



by:

I have been a repeat customer. They have stood behind the product and service has been great.



by:

It's a great product it does everything that is supposed to do highly recommend getting it



by:

I have a 2" collar style coupler. It fits, but not as rock solid as I had hoped. I found that reversing the lock (with the keyway facing the tongue) worked best, but that makes it a bit fiddly to get the key in the lock.



by:

easy peezy transaction . no headaches at all !!!!!



by:

Works great, no problems with functionality. However I use this on a trailer on the Gulf coast, and the finish is already shot with rust. Would not recommend this finish in this environment.



by:

I liked how you shipped my product asap and got to me fast. Thank you



by:

Having one key to match 7 trailer locks is a great plus.



by:

Perfect fit. The lock looks great and is a much needed accessory for RV's.



by:

Wow amazing product and easy to install .More heavy than I thought.



by:

This works great and Etrailer was bale to get it keyed alike to my hitch locks also.



by:

The product showed up on time the quality looks real good just installed them on my 5 x 8 utility trailer and my RV trailer so far so good thank you for the fast shipment and the tracking system you have works out real nice have a great day



by:

Delivered early and great product that fits. Thank you



by:

This is exactly what we needed... Our "OTHER" hitch lock was overpowered in a matter of a minute, we stepped up our game with the combination of this Power house of a securement system AND a 'DENVER BOOT'



by:

Good Lock.



by:

the product is of excellent quality and beefier than other products.been my first order from you my only issue was following the tracking . It was stuck in Michigan for a week on line and I was notified by my gf that the package was delivered after I had just looked and it was still in Michigan according to the order number. You have an excellent website Best I've seen by far anyplace. Awesome videos to help . Thanks to all at Etrailer.



by:

Got this coupler lock to fit securely on my trailer. For the most part, this lock appears robust. This with a good cable lock through the wheel should be an effective theft deterrence.



by:

Looks very sturdy. Fit my trailer coupler, which is 4 inches wide, where other locks would not fit.



by:

I found what I needed quickly. I paid for three day shipping and it got here early! It turned out to be perfect. The boat we were selling sold to the first person interested, which would have been after the lock arrived. Very pleased.



by:

This thing is BEEFY!!!!! This will work great, wish I had known about this product years ago!!!



by:

Fits well over the trailer ball. Strong, well made.



by:

Love being able to get this to match a previous purchase so the keys matched.

  • Can the Master Lock Trailer Coupler Lock Be Re-Keyed Before it is Shipped?
    I really wish we could rekey these because we get the request all the time but we just can't do it. I have reached out to Master Lock on this subject before and they have told me you can take the Master Lock Trailer Coupler Lock item # ML389DAT to a lock smith and have it rekeyed yourself but they won't do it. If you are looking to purchase multiple coupler locks that can be opened with the same key I recommend the Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers - Key...

  • Recommended Coupler Lock for Curt Channel-Mount Coupler
    Based on the lip on the Curt Channel-Mount Coupler - Squeeze Latch - 2-5/16" Ball - 15,000 lbs # C25328 you will be unable to use the # e98895. The # e87ZR might fit, but I would question how secure it is once again based on the lip on that coupler. Instead, I would recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-316. This is a universal lock that will secure over the top of the coupler and uses a bolt-blocked locking system to prevent...

  • Wheel Lock And Coupler Lock Recommendation For Trailer To Deter Thieves
    The best wheel lock system we offer is the Lock'em Magnum Wheel Lock, part # RA-25. This system will work on 12 to 17 inch wheels. One side works on 12-15 inch wheels and the other side works on 15-17 inch wheels. The arms measure 1 inch X 7/8 inch at the narrowest point and would be extremely difficult to cut off with a bolt cutter. For added security, you may want to check out part # FA86-0015-316. This is a coupler lock that will work on 1-7/8 inch , 2 inch, and 2-5/16 inch couplers....

  • Replacement Coupler Lock to Replace Reese Tow and Store Lock Kit
    Replacement keys are no longer available from Reese so replacing the Reese Tow and Store Lock Kit part # RP7014700 is the best and only option I can offer. If you broke the key off inside the coupler lock, you may consider using a Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers part # FA86-0015-316 because Fastway does have a variation of key numbers for security and produces replacement keys if this ever happens again in the future.

  • Replacement For Coupler Lock With Lost Key
    There are no replacement keys available for the Gorilla Guard coupler locks; the best we can offer is to remove it and replace the lock itself with one that has replacement keys available, the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-316.

  • How To Choose a Surround Style Trailer Coupler Lock for a Trailer Coupler
    I do have options for you but coupler locks aren't specific to the trailer, they are universal and based off the design of the coupler. We can't look up what type of coupler any one trailer uses but I can offer you a universal trailer coupler lock that works on nearly every coupler, the Fastway Universal Trailer Coupler Lock part # FA86-0015-316 which is a personal favorite of mine. It comes with two keys and you can order multiple with the same key if you have more than one trailer. I...

    The Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" # FA86-0015-316 will work with a coupler that is 4-1/2 inches wide and are a great (not to mention popular) style of lock.

  • Can I Carry 4 Kayaks on Malone MicroSport Trailer?
    I'll start off by saying that it isn't recommended that you add longer crossbars to the Malone MicroSport XT Trailer # MPG460XT because adding too much weight outside of the wheels will effect the stability of the trailer when cornering. With that being said, the crossbars that are included on the trailer will allow you to use your Thule Hull-A-Port XT TH848 spread out to acommodate the 4 kayaks you're wanting to carry without any issue. However, I believe I have a better solution that...

  • Is Fastway FA86-0015-316 Universal Trailer Coupler Lock Available Keyed Alike in Large Quantities
    It's very easy. Just go to the linked product description page and order 14 of the # FA86-0015-316 then add to your cart and check out. These will all arrive with key # 316. There are multiple key numbers to choose from. For example # FA86-0015-313 would include key 313. Check out the attached video for more information.

  • Multi-Fit Trailer Coupler Lock Available Keyed Alike
    Master Lock Trailer Coupler Lock # ML389DAT cannot be keyed alike but we do have similar multi-fit coupler locks that can be ordered in multiples that will all be keyed alike. I linked a page showing all of them, but the one I strongly recommend based on very high customer satisfaction is the Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers - Key 316Item # FA86-0015-316.

  • Does Fastway Coupler Lock FA86-0015-316 Work Correctly With 2-5/16 Coupler?
    The Fastway Universal Trailer Coupler Lock # FA86-0015-316 you purchased should fit in the coupler and be somewhat tight once latched as shown in our video, but it doesn't make much of a difference if it is not tight to the coupler. Once the top bar is locked down on top of the coupler it makes it so that the lock cannot be removed, so it still works as designed. I included a video of the # FA86-0015-316 for you to take a look at.

  • How to Replace Lost Key for Diversi-Tech Coupler Lock
    I spoke with my contact over at Fastway, who purchased Diversi-Tech a few years back, and they were able to tell me that D/T (like Fastway) only put the lock numbers on their keys; there is no way to tell which lock core was used in your D/T coupler lock without having the original key (or noting it somewhere when you purchased it). If you happen to have saved that number, please let me know what the 3 digit lock core number is and we may be able to find a replacement key that will work. If...

  • Do Trimax Dual Purpose Coupler Locks Use Unique Keys
    The Trimax Dual Purpose Coupler Lock and U-Lock # TMX77FR uses unique keys for the locks. If you were to buy two of these I would expect the keys to be different. If you're looking for a similar lock with a keyed alike option I recommend the Fastway # FA86-0015-316. This also fits 1-7/8", 2" and 2-5/16" ball couplers. You can actually choose the key number, in this case it is 316, so the keys will work with however many you need. If you don't like 316 I have attached a link below which...

  • Recommended Coupler Lock for a Tie-Down Engineering TDE Model 660 Brake Actuator
    I have two recommended options for you to lock the Tie-Down Engineering (TDE) Model 660 Brake Actuator, the Master Lock Trailer Coupler Lock part # ML389DAT or the Fastway Universal Trailer Coupler Lock part # FA86-0015-316. These are my two favorite trailer coupler locks and they will both work well with your brake actuator. The Master Lock is our most popular option but the Fastway is a bit beefier so this is actually what I recommend for you. The Fastway also has a cover for the lock...

  • Coupler Lock For a 2014 Rockwood Roo 21ss
    I looked up pics of the coupler on the 201 Rockwood Roo 21 SS and that the style of coupler is compatible with the part # FA86-0015-316 that you referenced. You will just need to measure the width of the lip on your coupler to be certain. The # FA86-0015-316 is compatible with couplers that have lips up to 4-1/2 inches in width. If yours measures less than that, as I suspect it will, it should work very well. Since you are looking for a hitch lock and coupler locks I would recommend you...

  • Can Locking Pins Be Used With the Sleeve-Lock Trailer Coupler
    The best option we can offer you to secure the Sleeve-Lock Trailer Coupler part # CTA-196 is with a wraparound style trailer coupler lock, the Fastway Universal Trailer Coupler Lock part # FA86-0015-316 is what I recommend. I don't really have any pin locks that could be used with the coupler as most pin locks we offer are made for much larger holes. I understand someone could unbolt the coupler but the odds of them being able to do this are very low.

  • Coupler Lock For Coupler That Is 5 Inches Wide
    Unfortunately, none of our wraparound coupler locks, including the Fastway Universal Trailer Coupler # FA86-0015-316 you mention will fit a 5" wide coupler. The best we offer for an extra wide lip is the Blaylock EZ Lock Trailer Coupler Lock for 2-5/16" Lipped Couplers # BLTL-34 since it does not wraparound the coupler, and will fit up to a 2-5/16' ball.

  • Recommended Trailer Coupler Lock for Pole Tongue Trailer
    I'd recommend a universal coupler lock set like the # FA86-0015-316 from Fastway. The coupler lock is compatible with 1-7/8, 2 or 2-5/16 inch couplers. I'd also go with a latch lock like # e98887 to prevent the coupler from coming unlatched while towing. It'll also prevent the trailer from being hitched up.

  • Trailer Hitch Coupler for Micro Minnie 2108TB.
    Any lock on a coupler will deter people from taking it, but at a certain point almost any lock can be destroyed. I think that the Universal Coupler Lock # FA86-0015-316 is more breakable than something like this lock # e87ZR. This is for a 2-15/16 inch rolled lip coupler. It's a solid piece and there is not as easy of a spot for someone to take an angle grinder to it and cut it off. It will take a lot longer for someone to get through this kind of lock.

    The only trailer coupler lock we offer that will fit multiple ball sizes, different styles of trailer couplers, and can be keyed alike is the Fastway Universal Trailer Coupler Lock part # FA86-0015-316. This lock has an extremely universal design, anti-drill pin, and lifetime warranty. Check out the attached video to see how the coupler works and how the keyed alike feature works.

    The best lock recommendation we'd have for your Bulldog Coupler part # BD44150WH301 would be the Fastway Lock part # FA86-0015-316. Although this is a universal style coupler lock it's design allows it to fit basically all coupler styles well enough to be a very effective coupler lock and it can be ordered "keyed alike." I attached a review video for this lock for you to check out as well.

    The highest rated and most popular 2-5/16 inch trailer coupler lock we carry is the Fastway Universal Trailer Coupler Lock, # FA86-0015-316. This lock actually will fit 1-7/8, 2, and 2-5/16 inch couplers. It features a pick-resistant lock cylinder and dual-action, bolt-blocked locking system that locks both arms instead of just one. To add even more security, you can use the The Wheel Club - Tire and Wheel Lock, # WI490, to one of your trailer wheels. This wheel lock fits tires up to 28...
