Video Transcript for DeadBolt Blockhead Trailer Coupler Lock Review

Today we're going to take a look at the Deadbolt Blockhead Trailer Coupler for Flat lips for 2 inch and 2 5/16 ball couplers, part number TCL3-AS. This is a aluminum, rustproof coupler lock to prevent trailer tow-away theft. It'll fit trigger-style couplers. The sturdy lock will deter trailer theft by preventing hook-up. It's made of a heavy-duty, extruded, tempered aluminum body so it's strong, durable, and rustproof and the push-button lock sits on the front for easy access. It also has a shuttered key hole to keep dirt, dust, debris out, and will help prevent from freezing up by preventing moisture from getting inside.

The double-sided key, automotive style is easy to use. Now, let's go ahead and show you how it installs. Here we have the Deadbolt Blockhead Trailer Coupler Lock. The extruded aluminum is grooved to fit around the flat or rolled lip of the trailer tongue. As we unlock the tumbler, the pin in the bottom will drop, we can remove the key, slide it over our coupler, pushing the pin back up, the tumbler in to lock it, just like that we've added security and helped prevent trailer theft. Then to remove it, we simply take our key, unlock the tumbler, the pin drops out, and we can slide it off our coupler and we're ready to hook up to our vehicle.

Just like that, we've completed the install and operation of the Deadbolt Blockhead Trailer Coupler Lock for the Flat lip 2 and 2 5/16 ball couplers, part number TCL3-AS. .

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

by:

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

by:

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.

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

Review from a similar DeadBolt BLOCKHEAD in Trailer Coupler Locks


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


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

Review from a similar DeadBolt BLOCKHEAD in Trailer Coupler Locks


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

Review from a similar DeadBolt BLOCKHEAD in Trailer Coupler Locks


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

Review from a similar DeadBolt BLOCKHEAD in Trailer Coupler Locks


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

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

  • Coupler Lock for Demco Channel Tongue Trailer Coupler # DM13203-52
  • You can use the DeadBolt BLOCKHEAD Trailer Coupler Lock # TCL3-AS if you are looking to keep your trailer from being coupled to. If you are looking for a lock that prevents it from being uncoupled then that would be the DeadBolt part # 28012.

  • There will be a number on both the lock core and keys for the DeadBolt BLOCKHEAD Trailer Coupler Lock part # TCL1 for 1-7/8"/2" or part # TCL3-AS for 2"/2-5/16" couplers. This number is usually a zero followed by two other numbers. The three digit numeric value will correspond to the correct cut needed to operate the lock. If you already have a DeadBolt BLOCKHEAD Trailer Coupler and just need the replacement keys then you can use part # CTJKEY. Once you arrived at the product page for...

  • Can DeadBolt Coupler Locks and Hitch Receiver Lock be Keyed Alike?
  • All three locks you mentioned are from DeadBolt, and because of that you will be able to get them all keyed alike. You will need to select "Keyed Alike" in the drop down menu when ordering DeadBolt Hitch Receiver Lock # RH5-XL, DeadBolt Stainless Steel Trailer Coupler Lock # RC2SS and DeadBolt BLOCKHEAD Trailer Coupler Lock # TCL3-AS, and the three locks must be placed in the same order.

  • 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.

  • Recommended Coupler Lock for Demco Channel Tongue Coupler with eZ-Latch
  • The Demco Channel Tongue Trailer Coupler - Zinc - 2-5/16" Ball - 3" Channel - Bolt On - 18K # DM13203-95 has an integrated 5/16 inch pin hole with a 3 inch span for that lockable feature. I recommend using the Trailer Coupler Lock # 28012 which has a 3-3/8 inch span and is 1/4 inch diameter. For further security when disconnected from your vehicle, I recommend the DeadBolt BLOCKHEAD Trailer Coupler Lock # TCL3-AS.

  • 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.

  • Keyed Alike Hitch Lock and Coupler Lock Recommendation for 2-1/2 inch Hitch
