Video Transcript for Tow Ready Gorilla Guard Trailer Coupler Lock Review

Today we're going to be taking a look at the Tow Ready Grill and Guard Coupler Lock. We've got two sizes available. The 2" is part number 63228; the 2-5/16" is part number 63227. These trailer coupler locks are great for securing your unattended trailer, preventing anybody from being able to hook up to them. They offer a gorilla guard design, which as you can see is a nice, heavy-duty lip, with structural supports all the way around our lock to prevent any kind of tampering. It has a single action, cylinder style key. Push in, a quarter turn out.

Key is removable. To attach it to your trailer we simply bring it onto our coupler, push up on the lock. As you can see that's all there is to it. Our trailer is secure, we can leave it for a while and don't have to worry about anybody hooking up to it and it getting taken from us. Now that we've gone over the details and you've seen how it works, that will complete today's look at the Tow Ready Gorilla Guard Coupler Locks, part number 63228 in 2" and part number 63227 in 2-5/16". .

Trailer Coupler Lock - Gorilla Guard for 2" Couplers - 63228

Average Customer Rating:  4.8 out of 5 stars   (92 Customer Reviews)


Very impressive hitch lock. I put it on my log splitter and I feel like it is safe now. I had one stollen, but I don’t think they will get this one.



I now have one on my trailer and pull behind smokergrill as well as my log splitter. So the locks have worked well. Great product.


The coupler lock works as advertised and the etrailer measurements were perfect. The tie down brackets were also easy to install and work well for holding down my ATV and UTV. The spare tire carrier, wheel and cover all came from etrailer. They fit perfectly.


Excellent product, excellent customer service. Highly recommend.



I like the coupler lock very much. Its worked perfectly as advertised.

@David We're glad to hear that, thanks for checking back in!


Great lock


Ordered this item for my brother. He said it is the absolute best lock available. The price is right also.


Great lock, many happy customers


Feels solid. The lock is beefy. It does not feel cheap. It fit my haulmark 6x10 perfectly.


Trailer hitch lock still working great 1 year later. An advantage of this cylinder lock system is that once you take it off the hitch, you can take the key out and when ready to lock your hitch again, just slide it on and push the lock up into the ball receptacle - job done.


The Gorilla (trailer hitch) Guard works better then any other guard I've used...

Steven K.


Excellent protection...easy on and easy off...key works great.


Seems very well built. Now I have peace of mind that no one will steal my boat at a storage facility.


Lost my old one so replaced it with this one. Works great.


Great transaction , great product , purchased trailer tongue lock that comes with two keys for $29.95.(FAIR PRICE) . I could not order product with additional keys, I had to wait for the lock and then order additional keys. TWO ADDITIONAL KEYS COST MORE THAN THE LOCK , $37.84 for two keys. Just doesn't seem right!!!


I purchase 3 trailer locks from etrailer, Heidi took care of the order and everything was shipped out promptly and handled correctly. Yes I plan to order more from etrailer in the future. Very satisfied, Jack


I have 4 of these locks on my trailers for the last 20 plus years and have never had any issues whatsoever. Best lock for A frame type couplers.


I purchased my trailer used, but in excellentshape and the seller had the Gorilla Guard Trailer Coupler lock on the unit. He would not let the lock go with the trailer and spoke so highly of it, I purchased my own. I could not be more pleased with the product or Their service was speedy and flawless and the price of this item ranged widely from several vendors and their price was the best by far.


Have been looking for a drop hitch and vehicle/trailer flucuate between 3 1/4" to 4 1/2" drop depending upon load(s). Researched many and BW seemed to be best/recommended choice. Haven't used yet, but very solid construction.


This trailer coupler lock fits my trailer well.
Shipping was quick. I am satisified.
Thank you, etrailer.


Works well. Small hassle to get underneath to lock or unlock. Would recommend to others.



Still works well.


Havn't had the product long enough for a complete evaluation but it is exactly as I expected it to be and fits my 10x6' trailer that I haul my trike and other things on as expected and as decribed. I use it along with a hasp lock and plan to take vacation with it soon.


Fit right onto a standard 2" ball coupler. Very easy to lock onto trailer. Should deter most thieves effectively.


This by far is the best hitch lock. I've had others but this one takes the cake.. Easy to use and not some off the wall color like some others... Great buy for the price


E Trailer is the best of the best for there service.Christy who helped me place my order was helpful and shipping follow up was most helpful. I would buy from E Trailer again!


Installed easy enough, looks nice. Hopefully the Mission trailer will remain in the church parking lot with this added protection. Glen, Smithfield


Great product and this is my second purchase for new trailer. Fast shipping and I can always seem to find what I need here. Great customer service too, if I have questions.


Love the product and purchased another one 18 years prior, never a problem. The only disparaging remark is that I could not purchase additional keys and to have the keys replicated is not possible because of the design. But all in all, I would recommend the purchase of this product.

Thanks for the 1 year follow up Gene, if you would like replacement keys CKEY-BS will work for these Gorilla Guard lock. You will need to enter your existing key number.

Gene R.


I actually have two of these locks, the one I bought about a year ago and one that I purchased in 1999. They both operate perfectly although I have to put some WD-40 on them occasionally as they will bind up and I have to play with them to get them to operate, other than that, a great product.

See what our Experts say about this Tow Ready Trailer Tongue Lock

  • Coupler Lock for 2016 Jayco Jay Flight 27BHSW
    If your 2016 Jayco Jay Flight has a coupler for a 2-5/16 inch hitch ball, you will likely want to use the coupler lock # 63227. If the coupler on your trailer is for a 2 inch hitch ball, check out lock # 63228. These locks fit around the lip running along the bottom of the coupler. If your coupler does not have this lip, feel free to send me a photo of the coupler whenever you get the chance and I will be glad to make a more specific recommendation.

  • Does Every Gorilla Guard Coupler Lock Come with Same Key
    Each Trailer Coupler Lock part # 63228 that you referenced comes with a unique key. They would not all come with the same key so you wouldn't have to worry about someone else with the same lock being able to unlock your trailer.

  • 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...

  • Gorilla Guard Coupler Locks for 2-Inch and 2-5/16-Inch Ball Couplers
    We do offer a version of the Gorilla Guard for 2-5/16-inch couplers, part # 63227. Part # 63228 that you referenced fits 2-inch ball couplers.

  • Coupler Lock Recommendations for a Titan Multi-Fit Coupler
    You will need to take a couple measurements on your Titan coupler to be sure it will fit, but I would recommend you get a Tow Ready Gorilla Guard # 63228. This lock will slip on the front of your coupler and should work well as a theft deterrent. The width of your coupler (including the lip) should not exceed 3-13/16 inches and the lip should not be thicker than 5/16 of an inch. Another option you have would be the Master Lock Universal Trailer Coupler Lock # 379DAT, this will work similar...

  • What Materials are the Gorilla Guard Coupler Locks Made Of
    I called the manufacturer regarding the construction of the the Gorilla Guard Locks, part # 63228 and part # 63227. The main portion is a black-painted SAE-903 spec. steel casting. I pulled the lock from our warehouse to take a close look. The lock and pin are cast as well and appear to have a zinc coating. The keys are brass.

  • Choosing the Correct Size Trailer Coupler Lock
    The coupler size should match the ball size it is coupling to. If you have a ball with a 2 inch diameter then you would need a 2 inch coupler lock. If the ball is 2-5/16 inches in diameter you would need a 2-5/16 inch coupler lock. For 2 inch we have the Trailer Coupler Lock - Gorilla Guard # 63228 that is featured in the video you cited. For 2-5/16 inch we have the Trailer Coupler Lock - Gorilla Guard # 63227.

  • Coupler Lock Recommendation for a 2014 Jayco White Hawk
    The Gorilla Guard part # 63227 would be an excellent choice for your 2014 Jayco White Hawk 28DSBH as long as the coupler on your trailer is designed to fit a 2-5/16 inch ball, the coupler width is not wider than 4-1/8 inches and the height of the coupler lip is not greater than 5/16 of an inch. If you had a 2 inch ball coupler you would want the 2 inch version of that lock, part # 63228. Another very popular and well-reviewed coupler lock is the Fastway Trailer Coupler Lock part # FA86-0015-318....

  • Are You Able To Get Replacement Keys For Gorilla Guard Trailer Coupler Lock # 63228?
    We do not carry any replacement keys for the Gorilla Guard Trailer Coupler Lock # 63228 as the manufacturer does not provide these. I recommend replacing your lock with the Trimax Dual Purpose Coupler Lock # TMX77FR. This will allow you to order replacement keys directly from Trimax by simply ordering the key based on the number stamped on the key. This way you could still get a replacement key if you lost both your keys.

  • Is There A Replacement Barrel And Key For A 2 Inch Gorilla Coupler Lock?
    We don't have any replacement parts available for the Gorilla Guard Coupler locks. You would need to replace the entire coupler lock with # 63228 to get the new barrel and key. I've attached a video of this product for you.

  • What Keyed-Alike Coupler Locks Do You Recommend for a 2-Inch and a 2-5/16 Inch Coupler?
    I have a solution for you. Unfortunately, Gorilla Guard coupler locks like the # 63228 can only be keyed uniquely (independently). They cannot be keyed-alike. For an option that does allow it to be keyed-alike, I recommend two of the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers. These popular locks are sold under multiple part numbers, each one corresponding to a unique key number so you can purchase as many keyed alike or keyed unique as you need. So if...

  • Which Coupler Lock Would Best Fit my 2-5/16 Inch Coupler with a 3-3/4 Inch Wide Lip
    The Gorilla Guard for 2 inch couplers, part # 63228, would be so snug it would not be easy to get on and off, not to mention the curved portion up front may not fit the larger 2-5/16 coupler nose. The Gorilla Guard for 2-5/16 inch couplers, part # 63227, would be a better fit, though it will accept couplers of a greater width than yours, it should not be loose enough that it would not be able to prevent theft. You could also look into a different style of lock. I have included a link...

  • Gorilla Guard Coupler Lock Recommendation for 2 inch and 2-5/16 inch Ball Coupler
    2-1/8 inch is not a standard hitch ball size. Because of that none of the locks we offer like the part # 63228 are going to fit. You might measure again to see if you happen to have a 2-5/16 inch ball which would mean you would need the # 63227 instead. If you do happen to have a 2 inch ball the part # 63228 would be a fit.

  • Recommended Coupler Lock For Adjustable Ball Coupler
    The HITCH-LOCK Trailer Guard Coupler Lock by Dutton-Lainson # DL13980 is a great option for both keeping your trailer coupler locked in place and deterred from theft. You of course need an external padlock like the Master Lock Padlock # ML1KA for this application. If you are just looking for a lock when the trailer is not coupled, I recommend the Trailer Coupler Lock - Gorilla Guard for 2" Couplers # 63228 or # 63227 in 2-5/16 inch.

  • Solution for Replacement Key for Fulton Coupler Lock
    Depending on the style of key you may be able to have a copy made. Outside of that option, there are no replacement keys available for your Fulton lock with a 605 key. If you lose your other key the only option would be to replace the lock with one like the # 63228 or # AMP89FR you were looking at.

  • Coupler Lock Comparison for Securing a Travel Trailer
    Any type of lock you put on your trailer will be a theft deterrent. I recommend using the Fastway Universal Coupler Lock, part # FA86-0015-316, because it can mount on 1-7/8, 2 and 2-5/16 inch couplers and it fits on a wide variety of coupler types. The Diversi-Tech lock will be harder and noisier to break off than the Master Lock coupler lock which is a better deterrent for thieves. Wheel locks are also a secure option, but can be tedious to apply and still gives thieves a chance to...

  • 2 Inch Trailer Coupler Locks that Can be Keyed Alike for a Fleet of Trailers
    We have several coupler locks for 2 inch couplers that can be ordered keyed alike but the Gorilla Guard # 63228 is not one of them. I have included a link for you to the ones that can be ordered keyed alike. A lock such as # e98895 is similar to the Gorilla Guard. You would just select the keyed alike option, near the add to cart button on the product page, select the quantity and they will all be keyed the same.

  • Are Replacement Keys Available For The Gorilla Guard Trailer Coupler Lock

  • Are Gorilla Guard Coupler Lock Replacement Keys Available
    Gorilla Guard does not offer replacement keys for their Trailer Coupler Locks like part # 63228 unfortunately. The only option is to replace the whole coupler lock. You may consider the Blaylock EZ Lock Coupler Lock for 1-7/8" and 2" Lipped Couplers part # BLTL-38 because they offer replacement keys and keyed alike options. They also use the barrel keys which are more secure compared to the standard keys. If you have a 2-5/16" coupler you'll need part # BLTL-34.
