Speaker 1: Today we'll be taking a look at the Curt Channel Mount Lock Set, part number C23556.Without any locks, this could be you.But with our locks installed, you're safe and secure. This locking system is designed to work specifically with your Curt Adjustable Ball Mount, part number C45900, and C45902. Both locks feature a barbell style clamping mechanism that will work with either the hitch pin or the ball mount pin. Four keys are included, and any key will work with any of the matching locks. There's a dust cover on the end of each lock to keep out dirt and grime. The curved handle on the hitch pin makes for easy removal and installation.They feature a 6-1/4" overall total length.Included in the kit you'll get one hitch pin, one ball pin, and two locks.
These locks are keyed the same, so you have a total of four keys.We will start by installing the hitch pin. Remove the old one, slide in the new one, unlock your lock, slide it on, lock it up, and close the dust cover. Next, we'll install the ball pin. Remove the old pin, slide in the new locking pin. Again, unlock the lock, slide it on, lock it up, close the dust cover, and you're good to go.
Either pin can be replaced with the locking pin to secure your ball mount. Now, with our locks installed, we can feel safe knowing that our ball and our adjustable mount aren't going anywhere.That completes our look at the Curt Channel Mount Lock Set, part number C23556.

This Curt lock set for adjustable channel-style ball mounts is keyed alike, and includes 4 keys.by: Nigel 11/03/2023
Everything fits well and holds tight, order came super quick and the staff here at E trailer are very kind and respectful, showed up 3 days early to the middle of no where Texas, thanks again yall
by: James12/25/2021
Seems to be sturdy enough to keep my new Curt 45900 adjustable trailer hitch secure to my vehicle. I like the fact that the keys are all the same. etrailer customer service is great! Thanks to Michelle!
by: Ernesto01/20/2021
The locks are big enough to fit both my hitch and ball hitch. 4 keys included makes it very convenient. Shipped very quickly.

The Locks are working great. Very happy with the product.
by: Joey05/27/2016
This locking pin is definitely long enough for the Curt 14,000 lb adjustable ball mount. In fact, its probably about a half an inch too long. The locking part flops around a bit, I wonder if it would come off with a good smack from a hammer. I'm going to try shoring it up with a few 5/8 inch washers.
by: Jim11/07/2016
Though the product looks to be of good quality, the design in my opinion is poor. When the locking portion is attached to the pin(s), there is a gap between the two. This gives a purchase point to a would-be thief to get a prying tool in there. This may seem nit-picky, but this is a security lock set that is supposed to protect a trailer and hitch ball assembly.
by: Quarter Master Paul01/12/2023
Bought in fall of 2018. Kept them lubed up and they worked flawless, until the day I left it on my back bumper after taking off the hitch and driving away. But in the two years I did have them. Flawless! I would have gotten them again, but by time I realized what I had did, I needed something now. FYI: Cheap ones don't last as long.
by: David 05/01/2023
As others have stated, these are good locks but it does appear to have a weakness of being able to pop the lock off with a pry bar.
by: Wes 01/27/2020
We carry several different trailers for our adapted sport programs, which meant we needed to get a hitch receiver with an adjustable height. This lock worked perfectly for our situation and would buy it again for our next truck.

Great lock and we have had no issues
by: Matt01/10/2023
They work but the locks are a little loose and I think could be knocked off without a lot of effort.
by: Darren08/07/2022
Exactly what I wanted. Heavy duty and fit perfectly. I installed this by myself in about 2 hours . Hitch, wiring harness and bracket.
by: Robert 10/07/2022
I like the fact that you don't have to use key to lock, push-on to lock
by: Bradley09/05/2020
These locks are great, I ordered more for my adjustable hitch, I've had one for about three years or more. They work great, ( I do put a little oil on them from time to time just to make sure)

These types of locks normally dont work. The Curt locks work and still work even now after a year I have not sprayed oil on them, there is no need, they are still in great shape! I highly recommend these locks
by: Grady M. 12/06/2013
I chose these items because they were suggested when I purchased a heavy duty ball hitch. They did not fit the hitch very well and I ended up purchasing a different locking pin for the hitch. The product is a great product and I will keep them for other applications, however, I believe a recommended item should complement the product being purchased not simply related.
by: James06/01/2016
What can I say about the locking pins? They fit. Hopefully the locks won't have to prove themselves, but there isn't a lot more to say about them unless someone tries to steal the ball or mount. Then we'll know how good they are at preventing theft.
by: Terry C.04/10/2017
Locks look pretty good. Little long for me, made spacers so you can't stick prybar
between lock and hitch and pop off. Easy to lock and unlock. Now I can relax when hitch is on truck and not hooked to trailer.
by: Tim01/14/2022
I'm thinking I probably just got a bad set of these but I have struggled with the locks ever since they were new. The keys don't want to work! Always have to fiddle and jiggle with the locks for an annoyingly long time to get them to work.

Perhaps some lubrication is needed for a smooth entry. Next time, if you want to try a barrel key like item # BD580400, they are easier to maneuver in my opinion.

I ordered these locking pins for my new ball mount trailer hitch so it wouldn't come up stolen some time. I liked the Master Lock pins better but couldn't get two keyed alike.
by: Thad06/21/2015
Good product, fit the 3" hitch on my '15 Chevy2500 with a little room to spare. I'd like to see another 1/4" for the hitch lock, but it did the job well.
by: Lyle12/08/2017
This is my second set that I have bought my son took over my first set.They are a great asset to my channel hitch.Both locks are keyed alike less keys to carry a round.And like always etrailer comes through with fast shipping and great prices.Thanks again
by: Levi M.10/15/2014
I read a review buy someone on the site to use these pins with the Curt hitch that I also purchased. Only one of them fit so that part isn't great, but the one that does fit still secures the hitch so that it can't be easily stolen/tampered with.
by: Larry05/09/2017
I ordered a hitch and locking pins. All were nicely packaged and delivered very quickly.
by: Harold B04/29/2017
Really an amazing outfit. The web page provides all the detail needed to make the right choice on parts so its right the first time. The staff are friendly and caring and the delivery was spot on. etrailer is how web shopping ought to be done. They truly set the standard.

Keeps the Curt Adjustable 2-Ball Mount from disappearing...:)
by: Chris H12/29/2018
Perfect way to deter a thief from stealing your nice adjustable hitch, the pin for the receiver was long enough to use in my ‘12 2500HD 2-1/2” receiver.

Works great. Like that both are keyed s ame.

See what our Experts say about this CURT Trailer Hitch Lock
- Weight Capacity of Curt Locking Trailer Hitch Pin Set # C23556Hitch pins like # C23556 do not have a weight rating or shear strength data because their actual capacities far exceed the abilities of the hitch or vehicle. Basically, the hitch or some other component would fail before the pin even comes close. The pins are 5/8 inch diameter steel. The straight pin has a usable length of 4-1/4 inches and the other 3-1/4 inches. The pins measure approximately 6-1/2 inches long overall.
view full answer... - Are All of the Curt Lock Sets C23556 Keyed the SameI spoke with my contact over at Curt about lock set # C23556. He said that while the exact number is not known there are potentially thousands of possibilities. One thing is certain though and that is that they are not all the same!
view full answer... - Will the Curt Lock Set for Adjustable Ball Mounts C23556 Work With a 2-1/2 Inch Receiver TubeYes, the Curt Lock Set for Adjustable Channel-Style Mounts part # C23556 will work with the 2-1/2" receiver tube on your 2015 Chevrolet Silverado 2500.

The typical outside width of a 2-1/2 inch trailer hitch is 3 inches so provided that the outside width of your hitch is under 3-1/4 inches or 4-1/4 inches, this lock set will work great for you.
view full answer... - Locking Pins for Curt Adjustable Ball Mount # C45902For Curt adjustable ball mount # C45902 the locking pin set is # C23556. The pins don't have an official capacity but technically 5/8 inch diameter solid steel is going to have a capacity much higher than the hitch or vehicle. The hitch pin has a useable span of 3-1/4 inches which should be long enough for the outer width of your 2-1/2 inch hitch but it never hurts to measure to be sure.
