Video Transcript for Hands-On with the Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles

Hello neighbors, Steve here with etrailer.com. Today we're looking at this replacement lock cylinder for your UWS toolboxes with the square paddle handles. This one is key to CH504. Like I said, folks, this is just gonna replace one damaged lock cylinder on your UWS toolbox with the square paddle handles only. It does not work with the drawer slide, dog boxes, T handles, or the push button locks. This is key to CH504.

You can see it engraved there on top as well. You've got the lock core, you've got the retainer nut here. That's how you would actually install it whenever you're putting it on. And then of course, when it's in place, the key will turn the mechanism. You get two keys and one lock core.

Again, this one is key to CH504. Folks, that's gonna wrap it up for our look at this replacement lock cylinder for your UWS toolboxes with the square paddle handles only. I'm Steven, thanks for watching.

I received it just a little while ago and have already installed it. Thank you so much, it fit just like the old one, and that gives me a spare key and a lock.

No problem at all with this lock and shipping and delivery was what I expected

by: Joey 09/13/2019

works great but I was not expecting to have to use the nut off of my old lock and I wasn't expecting to be able to use both keys on my old lock too.

by: Andy 08/27/2018

Exactly what i needed, the phone support is the best with this company. It fits my toolbox from my Trailex perfectly.

by: James Morris 01/31/2017

Very easy to install . Had installed and working in less than 2 minutes.
I am not a mechanic , but used needle pliers , and screwed the 2 nuts on tight. All is good , my tools are locked up safe now.
Thanks

by: John 08/20/2017

I was replacing the same style of lock and I find that it is hard to get the key in because of tumbler cover. Not a great design...John

Do you have a question about this Accessories and Part?

Replacement Lock and Keys for UWS Toolboxes
There are several different lock and key replacements for UWS toolboxes and each one is different from the next. There is a chance you could end up with the same lock and key that you already have on the box but you would just need to order a different number than what is printed on the lock face or key to get a completely different set. For example, if you ordered # UWSLOCKCH503 you would get a lock and keys for CH503. I have included part links to all of the replacements we have for...

Replacement Cam Lock Nut for UWSLOCKCH504 Lock Cylinder
Since the # UWSLOCKCH504 is already a replacement part, smaller parts such as the cam lock nut you mentioned are not available separately. The only solution is to purchase a new one which will include the lock cylinder and two keys as well.

Replacement Lock For RK Toolbox
It is hard to say if this is an exact fit since we do not carry RK locks, but my research tells me that the closest match is Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles - CH504 # UWSLOCKCH504. You will want to compare this to the one you have. If this does not look like what you are needing then you will want to contact the manufacturer.
