Was having a hard time finding locking hitch pin and wasn't sure which size would work. Having both the 1/2 and 5/8 sizes made it easier to order as I knew one of them would fit, which is the 1/2 inch.

The package arrive, though a little later than expected, but still only a day later so not that big of a deal.
However, the package was torn, & coupler pin was bent (must have been a LOT of force!) I"m not even sure how that codl have happened, considering how strong these are, but it's clearly bent, and where it happened while it was in its package because the oackage was torn where it still was tied to the pin, to it ripped as it got bent. In anycase, I really needed it so didn't have time to send it back .. fortunately, it still worked FINE! the bend was right where it woudl come out of the coupler latch anyway, so I only lose ONE step and I;l never want to lock it in that tight anyway so its' fine... but wanted to mention that here. I DO love the lock set though, they lcok and hold very easily and matching keysh is a big help
by:
Good variety of pins. Has worked well for securing our bike racks and avoids the cotter style pins that this particular rack came with.
by:
works good but can sometimes get in the way of the safety chains clipping into the loops on the hitch.
by:
The Reese hitch pin is too short to go all the way thru to put the lock on. I have a 2” class 5 hitch.

No sign of wear and working great even after a year of exposure to the elements.

by:
Nice set for hitch/receiver and trailer hitch lock to help prevent theft while your trailer is connected to your truck! Rubber sleeves help protect the tumblers. What I would have loved to see, was a way to coordinate the matching key for the "EZ Lock Trailer Coupler Lock" and this set, so that I could manage all of the three locks with one key. I get around having two keys....but would be a nice feature to provide buyers!

Locks are holding up just fine after a year! But, I still fall back to my desire to have the ability to match the 3 lock combo with a hitch lock that matches the receiver lock and the trailer hitch lock for storage. This would be the proverbial icing on the cake....

It Works! One key for both locks.

After a year of use, the lock has held up great. Definitely recommend it.

by:
Overall, these are nice. The quality of the lock is okay, but it doesn't have the smoothness of operation or key fit that you see in top of the line locks. The rubber cover is a little loose. Overall, it is a good buy for the price.

Its been a year and I can say that this is a tough box. I discovered the hinge-lid pin had not been installed correctly, but this was a quick fix. This seems to be weathering the sun and the rain nicely!

by:
Works as advertised, and I like the stainless steel. It's nice the one set of keys work for both of the locks too. I have a 2016 GMC Sierra, which has large holes through the 2" receiver hitch. The pin with this set fits great, with very minimal play. I also appreciate the design of the perpendicular lock with the receiver pin, it makes installation and removal much easier with the space constraints of most modern hitch mounts.
by:
Love the security option for both the trailer pin and also the car side hitch. Especially using the same key. It add an extra step of security. The dust cap really works, I haven’t had any issues after use for about a year
by:
Works perfectly. Used it for towing a 10,000 lb. utility trailer. Have been using it every day since I received it. Every time I need to change hitches the lock always works effortlessly. With the seal over the end of the lock it prevents dirt and debris from gumming up the lock. Would buy it again.
by:
Used these on a 17000 km trip over 3 months in a variety of conditions. Like the matching keys. The coupler lock continues to work well. The lock on the hitch receiver seized at the end of the trip and had to be pried off with a crow bar.
by:
This lock works well to secure my extension adapter to my hitch. The price was reasonable and the delivery was speedy.

This Master lock hitch lock is still working fine after one year.

I purchased this item a year ago and as described it works great. I have not had any issue with the locks functionality in the year i have used it. I like that this gives me one key to manage both of my trailer security pins.
by:
I love shopping at etrailer.com, because they have every thing I need, and some times things that I didn't anticipate needing. We lent our bike carrier to a friend and when he brought it back, it was missing the lock that locks the rack to our vehicle, so that it doesn't get stolen; and the lock to the extension was also missing. Ugh! Fortunately, I was able to find EXACTLY what I needed at etrailer. This is one of the reasons I always come to etrailer, but the other reason is that have stellar customer support. I'm always treated special, which is great; but what makes their customer representatives superlative is that they're very knowledgeable. The last reason that etrailer deserves 5 STARS, is that their pricing is always competitive.
by:
I had been looking at the local hardware stores for a good way to lock my trailer and not finding anything suitable. This lock fits my need as I have a "Bulldog" type hitch on the trailer and the simple padlock I've used on my trailers in the past didn't work on the new trailer. This lock fit the hitch behind the sliding collar like I hoped it would, though I had measured carefully before ordering it.
Happy too that I can lock the hitch into the receiver with a matching key now. I know that no lock is theft proof, just trying to frustrate would be thieves so hopefully they move on to something else, like maybe gainful employment!
by:
Excellent product; fits perfectly as stated
by:
The receiver pin is the only piece that works. The smaller lock for the trailer lever is about worthless. Used two or three times and wasted 10 or 15 minutes trying to get it on right. Eventually just threw it in the trash.

  • How to Get Multiple Keyed Alike Trailer Hitch And Coupler Locks
    We have an option for you, though there isn't a way to get matching keys for a Master Lock # 2848DAT trailer hitch and coupler lock set as they don't have a Keyed Alike option for a second set. What you can do in order to use the same key for multiple trailer hitch locks and coupler locks is use the etrailer locks, and select the "Keyed Alike" option from the drop-down on their product pages. This will get you all the locks keyed the same so you only have to keep track of a single key....

  • Hitch Receiver and Coupler Trigger Lock Compatible with Toyota Factory Receiver Width
    The 2018 Toyota Tundra factory hitch is built up around the pin so it is wider than usual and will not fit the traditional 2 inch hitch pin like found in # 2848DAT. You will simply need the longer hitch pin. The Trailer Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # RH5-XL will work well for you and give you adequate space. If you want one that codes to your truck key, you can use the Bolt Lock # BL7023584. If you want the coupler lock as well then you...

  • Troubleshooting Masterlock Hitch Pin Lock with Key that Won't Turn
    Sounds like your Masterlock locking hitch pin part # 2848DAT has some frozen tumblers. I would recommend using the straw of your WD40 can to direct it into the lock core as much as possible. Then use the good key to help get it into the lock core. To do this basically you'd want to repeatedly insert and remove the key to help work it in. Several applications of WD40 might be required.

  • How to Stop Bike Rack Wobble When Using a 1-1/4" to 2" Hitch Adapter
    Good afternoon Larry! The Master Lock # 2848DAT you purchased will keep everything secure, but it doesn't have an anti-rattle feature to eliminate movement which explains what you're experiencing. Since you're using a 1-1/4" to 2" adapter, you actually have two connection points where movement can occur. I recommend the Roadmaster Quiet Hitch # RM-061-125 for the connection between your vehicle's receiver and the adapter, and the Roadmaster Quiet Hitch # RM-061 for the connection between...

    Hi Robert; the pin lock that comes with the # ML44VR will work but I've seen some issues with fitment for the surround lock on your coupler style because of the shape and design. Some people have had success with it on that Demco eZ-latch but I'm not overly confident. Are you wanting to upgrade from your current lock? You could still get the Master Lock Hitch Receiver and Coupler Latch Lock Set # 2848DAT which excludes the surround lock so those are keyed alike and then get a different...

  • Can the Master Lock Hitch Receiver and Coupler Latch Lock Set Be Keyed Alike?
    No, I am sorry Steve Master Lock does not offer their locks to be keyed alike. Instead of the Hitch Receiver and Coupler Latch Lock Set item # 2848DAT you were looking at, I recommend our 2-lock option that can be keyed alike item # e99039. This lock kit includes a 5/8" diameter hitch lock for 2" receivers and a 1/4" diameter coupler latch lock. When purchasing you'll want to go to the right hand side of the product page and select keyed alike above the add to cart button.

  • Can Trailer Coupler Lock Pins be Replaced?
    Hey William, thanks for reaching out! Usually there isn't a way to get just the replacement pin, but if you have a kit like the Master Lock # 3794DAT, we have some of it pieced out and you could get just the locking pins as part # 2866DAT or part # 2848DAT. This would come with an additional lock, but you would be able to simply swap it out to the one you currently have so everything is still keyed alike. If you let me know what specific lock kit you have, I'd be happy to see if we have...

  • How To Prevent Trailer Theft Beyond Hitch and Coupler Locks
    One easy way to prevent someone from removing the ball would be to use a ball mount that has the ball attached (welded) to the shank. That way you won't have to weld a ball to a shank that isn't meant for that type of modification. Some examples include # C42KR or something adjustable that locks like # DTALBM6600. A Wheel lock such as # RA-25 would also be a good idea. The trailer would not be able to be moved with a wheel lock like this on it. And the ball mount/ball may be enough of...

Instead I recommend the Curt Solid 2-Ball Mount for 2" Hitches - 2" and 2-5/16" Balls - 10K - Black # C45660 which has no drop, but the tongue weight of the trailer will push down on it and bring you very close to level.

  • Comparing Master Lock Hitch Receiver and Coupler Latch Lock Sets
    The main difference between the Master Lock Hitch Receiver and Coupler Latch Lock Set part # 1481DAT and part # 2848DAT is that the former is for 2" hitches and the latter is for 1-1/4" and 2" since it comes with both pin sizes (1/2" and 5/8". The locks are both very similar, I wouldn't say one is more secure than the other.
