Video Transcript for DeadBolt Blockhead Trailer Coupler Lock Review

Today we're going to be taking a look at the DeadBolt BLOCKHEAD. This is a very neat style coupler lock. It's available in a few different styles. The one you have here today is part number TCL3-YL. It's for the flat lip style of trailer coupler. It fits 2- to 2-5/16-inch balls. Part number TCL1 is available for the 1-7/8 inch and the 2 inch with the standard lip as we have here. We also have part number TCL2 which is for the 2-5/16 or 2 inch with curved lip or that little bit thicker lip. That's also available in a HiVis finish like we've got here. We have this available in an aluminum finish, as well.

If you don't want the HiVis yellow, drop the -YL off our part numbers. The way these work, very simply we've got right here on the front a push button style lock for ease of use. It's got a shuttered key hole. It's going to use an automotive style key that's been cut on both sides. That gives us a little bit of extra security. Slide that in.

As we turn that, our middle pin drops down. Slide that up onto our coupler, push it back up, and then push our lock in. As you can see, now we're secure. It's going to prevent anybody from hooking up to it and taking it down the road. The body itself is a heavy duty tempered aluminum, which makes it strong, durable, and also rust proof so we don't have to deal with corrosion as we go. As we said, this is the Hi-Vis yellow. Also available in an aluminum or a silver color. These can easily be keyed alike if you have multiple, different applications that you'd like to put them on.

They're made completely in the United States. Now that we've gone over the features and shown you how it worked, that will complete today's look at the DeadBolt BLOCKHEAD Trailer Coupler Lock, part number TCL3-YL. .

kind of too early to tell, but e-trailer has always been very helpful with getting us the right product and their customer service is second to none will follow up with this particular item once it's been used 559336

Blockhead coupler lock is well built and would certainly slow down a thief. The casual thief would certainly pass on trying to pry or cut this off. 218724

Great product, really like how etrailer.com was able to key the 2 locks I purchased identical. Great service. 186991



- TCL3-YL
by:

Can't give this unit the "excellent" rating since it did not fit my 2" ball coupler as it's advertised to do. Be concerned if you order this for a 2" coupler, especially if it's a smaller outside dimension trigger type. Once locked on it can be pulled off since it fit so loosely around the coupler itself. I'm sure it would work perfectly on a 2-5/16" coupler. Built very tough. 130439

The product was received and is just what I assume it would. The keys work great. 168004

by:

This small bit of hardware is easy to use and gives me a little more security than not using a hitch lock. Any pro who really wants to take your trailer can do so, but if there are a number of trailers together, this might be enough to make them decide to go try another one instead. 656721

I have ordered a few items in the past weeks. All were shipped quickly and was hassle free. The Blockhead coupler lock is an easy to use and great fitting lock. I use them on a cargo trailer and dump trailer in an area where numerous trailers have been stolen. The cheap locks at the local stores can be broken with a sledge hammer. So far these are a great product. 160002



- TCL3-YL
by:

The lock operates beautifully. Since I do not plan to use a sledge hammer to test it, I am hopeful the bright yellow paint is a good deterrent. I only wish the lock was a bit more snug to the trailer tongue. 156867

Review from a similar DeadBolt BLOCKHEAD in Trailer Coupler Locks


Purchased to secure my vintage Avion travel trailer. I have invested some money and labor in it and don’t want it to disappear! The lock fits the original coupler with a little side to side play. I purchased another lock that did not fit and was pleased that this one did, as discribed. Quality appears very good. 545431

Review from a similar DeadBolt BLOCKHEAD in Trailer Coupler Locks


The deadbolt lock provides higher level of security than the original hitch lock. I wanted to protect the bottom of the hitch and prevent someone from grabbing the trailer by using a ball type receiver or a 'C' type receiver on their vehicle. New lock installs in less than a minute. 493031

Review from a similar DeadBolt BLOCKHEAD in Trailer Coupler Locks


Worked as claimed. Have a 2 5/16" rolled hitch lip, so I had to remove the insert filler. Fits good. Trailer is stored in a open storage lot. Cheap deterrence. Delivered on time. 140222

This lock was received exactly as described, is made of extremely high-quality components. I was also very pleased that this item could be keyed alike with other DeadBolt locking products such as the hitch receiver lock. I strongly recommend this item without reservation. 74124


Comments

I stand by my review and I love these DeadBolt products.I found, however, that the Blockhead was just too big for my 1-78 coupler and slips right off.

Review from a similar DeadBolt BLOCKHEAD in Trailer Coupler Locks


So I had been looking for a keyed a-like lock set for my trailer and hitch/receiver for a few months. Well finally after not finding what I wanted and getting to the point of exhausting my internet search I called etrailer. I spoke with Ashley E. and she got to work on finding me EXACTLY what I needed!!! I purchased the DeadBolt™ trailer coupler (not in-use) lock, trailer coupler (in-use) lock, and hitch lock all keyed the same. They all worked great, looked great (quality), and best of all they were made in the U.S.A.!!!!!!!!! 607219

Second time I've ordered from etrailer and have been satisfied both times. Impressed with the selection and sale prices! Ordered on-line and received the items in 2 business days with free shipping.

Avoid this trailer lock. I had an Aluma tilt trailer stolen with this lock on the tongue. It was removed without cutting tools.

Ask the Experts about this DeadBolt Trailer Coupler Locks
Do you have a question about this Trailer Coupler Lock?


  • Will the Master Lock Coupler Lock # ML389DAT Fit a 4" Wide Trailer Coupler
  • We do have some options for you but the Master Lock Trailer Coupler Lock # ML389DAT that you referenced has a max coupler width of 3-1/4" so your coupler will be a little too big for it. For a coupler lock that can accommodate a 4" wide coupler we have the following: Tow Ready Gorilla Guard - # 63227 Fastway Universal Coupler Lock - # DT25013KA Master Lock Coupler Lock - # 377DAT DeadBolt BLOCKHEAD - # TCL3-YL Out of those options I recommend going with the BLOCKHEAD. It has...

  • Coupler and Latch Locks for Use with Demco Channel Tongue Trailer Coupler DM13203-95
  • The recommended coupler locks for use with the Demco Channel Tongue Trailer Coupler # DM13203-95 include DeadBolt parts # TCL3-YL and # TCL3-AS. For a latch lock you can use part # 28012 that will install in the single horizontal hole that is underneath the black latch.

  • Can Deadbolt Hitch Lock # 40107 be Keyed Alike to Coupler Lock
  • Yes, if you select "keyed alike" on the product page for the hitch lock part # 40107 and on the page for the coupler lock part # TCL3-YL you'll get both the coupler and hitch locks keyed alike. If you had a different coupler lock in mind you'd be able to do the same thing to have it keyed the same as the # 40107.

  • Recommended Trailer Coupler Lock Replacement for a Steal Shield Coupler Lock
  • We do have a wide variety of trailer coupler locks that can be keyed alike which you can find on the linked product page. Unfortunately Steal Shields went out of business so we do not have any options from them. Among the keyed alike coupler lock options is the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # DT25013KA. This is one of our most popular coupler locks and is compatible with many trailer coupler styles which is demonstrated in the attached review...

  • 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 # TCL3-YL 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.

  • Replacement Key Recommendation for DeadBolt BLOCKHEAD Coupler Lock # TCL3-YL
  • We do offer a way to get replacement keys for your DeadBolt BLOCKHEAD Coupler Lock # TCL3-YL. What you need is the part # CTJKEY. On the product page you will need to enter the key number you have and you would be good to go.

  • Are Replacement Keys Available for the Blaylock EZ Lock Trailer Coupler Lock
  • While it is possible to get additional keys for the Blaylock coupler lock in a round about sort of way, a better option would be to use a similar lock, # TCL3-YL or # TCL3-AS. You would wait to receive the lock and then there will be a 3 digit number on the keys. Enter that number where indicated on replacement key page # CTJKEY and the number of key pairs you want and those keys will be sent to you. Additional keys by themselves are not available for the Blaylock EZ Lock Trailer Coupler...

  • Recommended DeadBolt BLOCKHEAD Coupler Lock for Lipped Coupler 4-1/2-Inches Wide
  • The DeadBolt BLOCKHEAD Coupler Lock # TCL1 fits standard lipped couplers for 1-7/8-inch and 2-inch hitch balls up to a maximum width (including the lip) of 3-3/4-inches. Instead you can use their BLOCKHEAD Trailer Coupler Lock # TCL3-YL for 2-inch and 2-5/16-inch balls since this works with lipped couplers up to 4-1/2-inches in width.

  • Locks for Use with Titan Zinc-Plated Straight-Tongue Coupler T4853100
  • Yes, a coupler lock can be used on the Titan Zinc-Plated Straight-Tongue Coupler # T4853100. If you want to secure the trailer when it is not hitched, you can use the DeadBolt BLOCKHEAD Trailer Coupler Lock # TCL3-AS or the similar # TCL3-YL. Both of these prevent someone from hitching to your coupler. If you prefer a coupler latch lock you can use # 2847DAT from Master Lock. This type of lock works with the trailer coupled or not.

  • Can Multiple Products be Keyed Alike?
  • It would not be possible to get the Trailer Hitch Receiver Locks # RH5-XL,Trailer Hitch Receiver & Coupler Lockset # 7685, BLOCKHEAD Trailer Coupler Lock # TCL3-YL or. Deadbolt 10' Long Cable Lock # CAB-10 you referenced each keyed alike. The "keyed alike" option in the drop down menus only works for purchasing multiples of an individual product.

  • Recommended Surge Brake Actuator for a 2005 Load Rite Boat Trailer
  • Its sounds like you would like to replace the electric over hydraulic actuator you have on your 2005 Load Rite boat trailer in favor of a surge brake actuator. If this is the case then yes you can replace it and for that I recommend the Titan Brake Actuator part # T4822820. This actuator is an excellent option for your trailer. It has an electric lockout feature which will allow you to back the trailer up without hassle, adjustable channel to help level the trailer while in tow, and...
