My first choice in king pin locks didn't work, the wedge from the Reese Sidewinder prevented me from placing the cap all the way up/around the king pin. This Master Lock was my 2nd choice. Good visibility, easy to place, but something about the lock mechanism makes it a bit tricky to get closed. As usual, great service from eTrailer.com! 54407

I purchased this king pin lock for my fiver.......it fits perfectly and is well constructed. I have a Reese Fifth Airborne king pin ......the "wedge" is not an issue. I have purchased many items from etrailer and have been very happy with their service and products. No problem getting questions answered if needed. 335629

Review from a similar Blaylock Industries EZ Lock in King Pin Locks


Great wheel lock. The design and production of the lock is superb. Hopefully it will never be tested but if it is, I'm confident that it will do what it is designed to do. As shown in the picture, it will be used as part of a set of locks to protect our new T@B trailer. 207151


Comments

Thanks for the followup. In general Im still very satisfied with the lock. Luckily it hasnt been tested by some unscrupulous person. I have a very secure feeling when using the lock. I guess the only slightly irritating thing Ive found with the lock has to do with the key and lock itself. Compared to all other key locks Ive ever used, this is the only one where the key has to be turned and turned and turned until it reaches the end and the key can be removed. The same happens in reverse when unlocking the lock. You have to turn the key quite a few times to get the lock to where the bolt can be removed and the key can be removed. When youre sitting or laying on the ground putting the lock on or taking it off, this all can be kind of annoying. I wouldnt give up the lock for anything and Im sure it will last longer than Ill have the trailer to which I attach it but a re-design of the locking mechanism could sure help some future customers satisfaction.

Review from a similar Blaylock Industries EZ Lock in King Pin Locks


We earlier purchased the BLTL-38 and found that it was about 1/8" too narrow to fit on our Atwood hitch on our Aliner trailer. The -36 looked like the next size up for our 2" ball hitch. The -36 is a bit too far in the other direction, slopping about excessively. I stuffed a cheap socket wrench socket over the locking pin to take up some of the slop, which seems to help. It seems like a very well made and elegant product that will stop the casual trailer thief. Someone with a torch or Sawzall should be able make short work of the lock, but hopefully there isn't a ring of trailer thieves out there. :-) Finding the hitch lock that will fit your trailer like a glove will require a careful dimensional index of trailer hitch types and sizes, or a shop that has everything and will let you try them on for size. 162796

Happy to contribute to the community. I know that I appreciate good input from other ownerspurchasers of products to help me make a better informed decision.I would add to this review that it would have been nice if Blaylock could have plated the center moving pin to prevent rust. Ive coated mine with grease and it still rusts at the first of rain.Hope you had an excellent Thanksgiving.

Review from a similar Blaylock Industries EZ Lock in King Pin Locks


This lock system is simple and weather exposure should not be a hindrance for removal when needed. I would like to see the pin made of hardened steel. May get a machinist to fab one up out of a harder Rockwell rating. Painted it Orange and it contrasts very well to the black trailer frame. This is a visual que for those passing by the county road, that the coupling has 'something' on it. The Master lock appears to be of a higher quality the the same design but sold for storage unit use. It may be made by Master but have no way of knowing. The lock operates very smoothly and the stainless body is perfect for outdoor application. A shout out to Jennifer who has been providing excellent customer service from day one. This means I will use etrailer for future trailer needs, thanks to her. Hope this helps others. 398959

This theft deterrent works just fine, super easy to use WHICH MEANS YOU SHOULD USE IT !!! Any theft system is really to stop the person that is not fully prepared to steal something. So using this is 80% of the solution to having your trailer borrowed permanently. Easy to put on and you have to use the disk style lock as this is the only lock that can't be cut into by bolt cutters. Do not use a cheap pad lock or the thieves will go at the WEAK part of the system. 114977

So far so good. When I ordered the item, your operator seemed to want me to have ups deliver it or pay the lower rate of snail mail and they said it would be up to two weeks before I received it. I decided to go the cheaper route of the us postal service and I received my item within only a few days. Just felt like I was being nudged in the more expensive direction. Other than that, I'm happy with said product. Thanks 124606

Thanks for the email. I use both items constantly and theyve held up very well. The Blaylock coupler lock is exposed to the elements 247, and I take a little preventive maintenance by lubricating the keyway with WD40, but it has worked flawlessly. The trailer dolly is a back saver. Im very happy with both purchases and Im sure Ill be making more in the future.

I have used this product for 12 years on trailers to tow bars on SUVs and ordered two more. This is more practical for me because it can take a Combination hasp lock instead of a key like all other coupler locks, which I never seem to have handy. etrailer was very prompt on shipment of all the products I have ordered from them. Good products, excellent service. 158271

The coupler lock is easy to use and should deter the easy theft of my trailer. Because it is designed for both a 2.5" and 3.0" lunette ring, there is some play between the lock and my 3.0" ring, but not enough to impact its intended function. 218177

Review from a similar Blaylock Industries EZ Lock in King Pin Locks


I've been needing a new lock for my work trailer especially when the old one finally failed. I am a big user of the Blaylock locks for my trailer doors for the past 3 years. They work wonderful even in the Michigan winters. When I saw that the other locks of their lines could be keyed alike I jumped on getting more info. Once I talked to the company they did say the BLTL-34 can be keyed the same to my other locks. I called up etrailer and spoke to Leeza who checked for me and said yes it can. My new lock arrived in a few days and out of the box the lock worked perfectly with my original old keys (the new keys worked too). Now I carry one less key and have two additional spares. The price was right and the service was wonderful!. THANKS! 330652

Review from a similar Blaylock Industries EZ Lock in King Pin Locks


There was an unexpected shipping delay by the vendor, however, Bridget kept me informed with status updates throughout the delay. When I got the product, I took it out to the boat trailer for a trial fit. Got a scare when it only slid on half way. I couldn't see that the little tongue lever that slides under the ball when tight was protruding down just enough to keep the lock from fully sliding on. Once I realized that, I lifted up on the locking knob to pull that little lever up and then the lock slid all the way on. Good to go now! I dropped the rating one notch because it would have felt weird giving a security device an excellent when it is made of aluminum. 190659

This hitch lock is excellent would definitely recommend to anyone. It has been out in the weather for a year now and there are zero signs of corrosion/rust on any of the components. The only thing that has room for improvement is the way it fits the bottom side, it fits a little loose but it's still impossible to remove without destroying it. Adds peace of mind letting your trailer sit somewhere knowing it's not going anywhere without a battle. 293162

This is not a product review as I have not used the product yet. However, I wanted to rate your companies service as "Excellent". Immediately after I placed my order online I received a phone call from your company informing me that the item was out of stock at this warehouse but was inbound and it would be around 3-4 extra days for me to receive my item. This was the first time a company had ever called me to explain this. Most companies would have just let me wonder about why I had not received my order. In fact I still feel that I received my item in a very short time period. Great Job! 479715

Review from a similar Blaylock Industries EZ Lock in King Pin Locks


After looking at dozens of trailer coupler locks I chose the Baylock TL-33 because of its simple, clean design and the ability to use a quality padlock vs the cheap Chinese made locking mechanism installed on most other coupler locks. The Baylock is made in the USA and is a high quality thick aluminum casting that will never rust and thick 3/4 inch steel locking pin. It looks very strong. I know that every coupler lock from every manufacture can be defeated by a thief given enough time and proper tools... but the Baylock is a great deterrent. 44181

The coupler lock is a great idea! Easy to use, and made from light weight cast aluminum. The lock pin will accept any standard sized padlock. I like that the lock pin also covers hitch latch, to prevent tampering. Pros: Light weight, small, simple, good finish, easy to use, cast aluminum wont rust or corrode. Cons: Cast aluminum, could be quickly cut through with hacksaw. Locks only keep the honest people from stealing your stuff, but its better than not having any lock. 172255

I have never seen another website that takes the time and effort to give you a product video to assist you with your purchase. Hats off to etrailer for their excellent customer service! 221916

Review from a similar Blaylock Industries EZ Lock in King Pin Locks


As a trailer dealership we were looking for a way that we could add an additional level of security to our inventory with out having to keep track of separate keys for each lock. the Blaylock provided the perfect solution it fit all the different coupler types that we have and with an order of master locks that are keyed alike I only have to keep one extra key on my ring. We will defiantly be purchasing more of them as our inventory expands. 266319
