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:

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

The lock has worked perfectly, no issues.



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:

Works great. I park my trailer in public areas on occasion. It hasn't gotten ripped off yet!



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:

High quality product. Lock bolt is stro ng.



by:

Perfect fit



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:

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



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:

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



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:

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:

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:

Delivered early and great product that fits. Thank you



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:

Good Lock.

  • Locks for Hasps and 2-5/16" Coupler With Trigger Latch
    We don't have an option that will allow for all of them to be keyed alike but I can get you down to one key for the hasp locks and another for the coupler lock. The Trimax Puck Locks for Trailer Door Hasps # TMX73FR comes with three keyed-alike locks with a 3/8" shackle. The shackle is hidden so there it can't be cut by a thief. These have a steel construction and chrome finish. The locks could then be paired with the Blaylock EZ Lock # BLTL-33 or Trailer Coupler Lock - Butterfly Style...

  • Security Locks For Dexter A-60 Brake Actuator Coupler # DX56FR
    We do have locks that will work with your Dexter A-60 Brake Actuator # DX56FR. The Coupler Lock # e98888 will allow you to secure the trailer to your vehicle when towing. This lock pin replaces the included push pin which comes with the actuator. For storage you will want to use the Fastway Universal Trailer Coupler Lock # FA86-0015-316. This can be used with the coupler lock above as well. I have linked videos for each of these locks near the bottom of the page which shows them being...

  • Keyed Alike Trailer Coupler Lock Recommendation for 6 Trailers
    A combination coupler lock would be a great idea, but we don't carry anything like that at this time. I do have one solution for you to consider that I can help you with. You could get the Fastway Universal Trailer Coupler Lock # FA86-0015-316. This lock can be keyed alike so you could order all 6 of the ones you need and they will all come with the same lock core and matching set of keys. Since you would have so many spare keys and they all would work for each lock this is a setup that...

  • Coupler Lock Recommendation for a Bulldog A-Frame Coupler 44150WH301
    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.

  • Recommended Universal Trailer Coupler Lock for Multiple Trailers
    The most universal and secure trailer coupler lock that can be keyed alike is the Fastway Universal Trailer Coupler Lock part # FA86-0015-316. This lock fits almost all trailer couplers that use a 1-7/8", 2" and 2-5/16" hitch ball. It can be ordered to come keyed alike by ordering multiples of the same part number since the part numbers correspond to the key numbers. This lock has a hardened chrome plating, anti-drill lock core, and comes with a lifetime warranty. It is a very popular...

  • 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.

These are my two favorite trailer coupler locks and they will both work well with your brake actuator.

    I walked out to our warehouse and pulled the Tow Ready Trailer Coupler Lock. The locking bar measures approximately a 1/2 inch in diameter. The representative at Tow Ready informed me that the lock is made of 1407 steel. I then contacted our representative at Fastway about the Universal Trailer Coupler Lock, part # FA86-0015-316.

  • Solution for Coupler Lock on U-Haul Trailer
    The EZ Lock Trailer Coupler Lock # BLTL-20 is designed to fit Bulldog Collar-Lok couplers so there is no guarantee it would work on a U-Haul trailer. For the same lock style I would instead use the Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-316. This is a universal application lock so it will fit most couplers instead of a specific style.

  • Coupler Lock for Demco Trailer Coupler DM14976-52

  • 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.

  • Coupler Lock for a 2 Inch Trailer Coupler
    Blaylock Total-Encasement Coupler Lock # BLTL-22 is designed for Bulldog Collar-Lok couplers which are more narrow than regular coupler so I do not recommend trying to use it. I recommend using a coupler lock such as # FA86-0015-316 or # 379DAT for your 2 inch coupler. I have linked review videos on both locks for you.

Instead, what you'll need is a surround lock that fits over the coupler where the hitch ball attaches and is wide enough to fit your lip, which is a lock from Fastway: - Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # FA86-0015-316 The Fastway # FA86-0015-316 fits couplers with a width up to 4-1/2 inches, comes with a pair of keys, and has...

  • What is the Difference Between the Fastway Coupler Locks # FA86-0015-303 and FA86-0015-316?
    The only difference between the Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers - Key 303 # FA86-0015-303 and the Fastway Universal Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers - Key 316 # FA86-0015-316 is the cut of the key. The # FA86-0015-303 comes with a lock compatible with Fastway key 303 while the # FA86-0015-316 comes with a lock compatible with Fastway key 316. Other than this difference, these coupler locks are exactly the same.

    I have a solution for you but the Blue Ox Trailer Coupler Lock item # BX88351 is not capable of being keyed alike. Instead you will want the Fastway Universal Coupler Lock item # FA86-0015-316. This coupler has the same abilities and functions. It fits most 1-7/8", 2" and 2-5/16" ball couplers. You will want to order as many of these couplers as you need and they will all be able to secure with the same key.

The # e87ZR might fit, but I would question how secure it is once again based on the lip on that coupler.
