I chose this Trailer Surge Brake Coupler Lock because of its ease of use. The screw on/off function makes installation and removal easy. I also purchased a Trailer Hitch Receiver Lock from e-trailer and had the locks keyed alike.



by:

It locked up in the tumblers and broke the key off in it while I was trying to get it unlocked...had to take a cutting wheel and cut the end off of it so I could use my trailer that day...I also do spray wd40 in all my trailer locks..maybe I got one that way made on a Monday or a friday...



by:

Have not got a chance to try the product yet. But I could not be more impressed with etrailer. Their shipping was prompt and communication was continuous. Thank you



by:

Perfect for coupler security



by:

It fit perfectly on my boat trailer act uator.



by:

Prompt service, easy and reliable tracking, and very fair pricing. All this combined with a huge selection makes it a very pleasant shopping experience



by:

Perfect for the Demco EzLatch on my utility trailer. Very easy to use and provides the security for my trailer that I sought.

Works very well, and as intended. Adds a sense of real security & safety.



by:

It was exactly what I wanted (and needed) and works as well as the day I bought it. I would recommend it.



by:

I was sent a follow up email asking how I liked the lock, and I have to say that I liked it enough to buy it a second time after I LOST THE KEYS!!! Because losing keys in my job!!! But yes it is a great lock for my trailer, because it has an odd coupler that a pin goes completely through it and you can’t use a standard padlock or coupler lock. The coupler locks sold at local stores were not long enough to go through the coupler, so I has to search the internet and I found this at trailer.com and it works! I would definitely recommend this lock if you have this style of coupler.



by:

Good value since the coupler lock works exactly as intended. Best part - even tho outside year around in Seattle weather, no corrosion since chrome plating more than adequate. Works on both electric and surge brake couplers with thru-body locks requiring extra length (span).



by:

Great Product! We ordered 6 of these for our fleet of trailers. Very convenient with all the same key. Also purchased the matching coupler locks.
We are very happy with both the products AND customer service at etrailer. They are our first and only call for trailer supplies.



by:

Just what I needed.



by:

Easy to use and fits my shorelander tra iler.



by:

Great locks working well. Like the idea that they are keyed alike!



by:

This works well and is good quality. I would recommend this product.



by:

Does the job but not sure it could hold up to a hammer.



by:

Works very well !



by:

These seem to be made well. Yet to be seen how they hold up over time. Having several trailers, the keyed alike feature was important to me and I was able to order the lengths I needed for the various coupler types. I saw some reviews indicating that the operation of these was slow or tedious. I found that insert the key, hold the key and spin the black end was simple and quick.

These are working well about a year later. Happy with them



by:

I ordered this lock and an etrailer branded coupler lock as etrailer’s website says it can be keyed alike to any other etrailer branded lock. I required them to be keyed alike. I received two locks that were keyed differently. There were extra lock cores in the box like someone was going to change them out, but shipped them without doing so. I followed up with customer service to inquire as to why and was told that these locks can only be keyed alike to the same type of lock, not other locks. I was then told they would send the correct replacement lock. Then was told that was not possible. I requested to return my order for a refund as the website was very unclear as to what locks could be keyed alike. I received a refund for less than the cost of one of the locks. Worst experience with etrailer ever. I won’t be buying from them again.



by:

Takes to long to un screw and come apart. Only used it a couple of times.



by:

Fast delivery!



by:

PURCHASED A TRAILER LOCK, IT FIT PERFECTLY. VERY HAPPY WITH THE PURCHASE

everything is still working great after a year of use.



by:

Does what it is supposed to. Not sure how easy it would be to snip or cut through, but I use it as a component of my security on a lightweight teardrop



by:

As described, perfect fit and looks good. Quick ship as well. Thank you etrailer.com!!



by:

I received the coupler lock. My coworker joked "That will only stop a honest man" You could cur this off with a hack saw in thirty seconds.

  • Comparing Demco Channel Tongue Trailer Couplers # DM16080-95 & # DM15931-95
    The only difference in the Demco Channel Tongue Trailer Couplers # DM16080-95 and # DM15931-95 is going to be the bolt pattern. One will have the 5-Bolt hole pattern and the other is going to have 4-Bolt holes. I have included images below showing the measurements for each of these bolt patterns to compare with what you have on your trailer. The etrailer Surge Brake Coupler Lock # e98888 will allow you to secure the coupler while attached to your vehicle. We also have a Pin # 37201211...

    I have another option for you, but the Bulldog Adjustable Coupler Lock # BD580410 you were looking at can not be ordered keyed alike.

  • Hitch Pin/Lock Needed For Demco Channel Tongue Trailer Coupler # DM15931-95
    For the Demco Channel Tongue Trailer Coupler # DM15931-95 you will need the Coupler Pin # 37201281 to ensure the hitch ball does not come unlatched while towing. You can also use the Lock # e98888 for additional security. The Pin # 37201244 you found only has a usable length of 2-9/16" and you need a minimum of 3" to fit your coupler. Also with the coupler pin opening of 5/16" you will not want to use a 5/16" pin as the pin is more likely to get stuck due to corrosion.

    The Demco Trailer Coupler # DM14976-52 has a 5/16" hole through the side of the coupler that will accept a lock. Our etrailer Surge Brake Coupler Lock # e98888 will allow you to prevent the coupler from being disconnected easily from your coupler. I recommend to use the Master Lock Trailer Hitch Receiver Lock and Coupler Lock Set # 3794DAT as this will also provide you with locks for your ball mount and a storage lock when you have to disconnect from the trailer.

    The best locking option we have for the Demco Trailer Coupler part # DM14040-52 is a pin lock. For this, I recommend the etrailer Coupler Lock part # e98888 which installs into the small pin hole on the side of the coupler. The pin lock will stop either a hitch ball from being coupled to the trailer or stop a hitch ball from being removed from the coupler, it can also be used as a failsafe while towing. Unfortunately, due to the design of the lock I don't think there's a surround style...
