Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles - CH502 - UWSLOCKCH502

Average Customer Rating:  4.6 out of 5 stars   (53 Customer Reviews)


I think you should be able to indicate if it's for a right hand or left hand swing door. Other than that they work great. I use these locks to replace ones on my dog trailer doors.


Everything came in a timely manner when I got the lock it was missing the lock ring and the threads on the look itself was damage so I was unable to use the my old lock ring on the lock. If It wasn't for that I would have gave it a 5 star review.

I apologize for these issues. Customer Service will contact you about it.

I will have our customer service team reach out to you.

Bought a used truck with a uws toolbox. Did not get a key for the toolbox and PO had either never installed the connecting rod between the latches or removed it on purpose.

Parts arrived as advertised. Took all of a minute to swap out the old lock for the new one. I could have just ordered a key, but I had no idea if the lock was in working condition. The new lock solidly locks the toolbox.

The rod connectors installed easily on the existing latch connecting rod and the set screws have a good seat on the rods. Set screws come with thread lock so no worries about them rattling loose.


Easy ordering, on time delivery & great product ! I will use again and will recommend to family & friends.


etrailer was my first choice when I did an internet search for truck box accessories. I am very glad I went with etrailer to find exactly what I was searching for! They have a large inventory of products and their pricing is very reasonable. I would most definitely recommend etrailer to all of my friends!




Delivery was fast and works great was easy to install


product was a great fit, delivered on time and price was reasonable.


Product was an exact match for the original lock and took less that 2 minutes to install. Was really impressed with how quickly I received the lock. Pleased with the product and will definitely order from etrailer again.


I'm very happy with the replacement lock cyl.for my tool box,I was also supprised how quick I recieved it.I will definitely be ordering my trailer supplies from from now on.

Perfect fit. Quality machine work. Key device works perfectly.


Product came in a timely manner. As I only needed the keys which work as they the lock fits but does not work with my latch without some modification which I expected.


very pleased with service I received. locks were just as described and shipping was fair and fast. will use again......


This is just a standard cylinder lock with keys. Nothing fancy, works like it should.


Very pleased with the overall service here at etrailer. thank u all


Parts showed up last week. Installed this weekend and working great. They were just as described in the listing. Easy to install. Great customer service so thank you.


Was correct, key also worked in other truck locks, but the eccentric was different, will have to try to modify it to work.


Very fast delivery and the correct part the first time


Product was good quality and received my replacement lock within a week of ordering it.

  • Replacement CH502 Lock Set for Delta Truck Tool Box
    While there's a very good chance that the UWS Replacement Lock Cylinder - CH502 # UWSLOCKCH502 referenced in your question is what you need for your Delta Truck Box, the two manufacturers aren't related to each other. We do not currently carry Delta products so I can't confirm that the UWS lock and key set will work on your box, but since the numbers are exactly the same it's likely that the two companies simply obtain their latches from the same source. If this lock set looks like what...

  • Installation of Replacement Lock Cylinder for UWS Toolboxes
    While I was unable to locate a diagram showing installation of the Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles - CH502 # UWSLOCKCH502 I did add a photo that should be helpful. The accompanying photo is of the Replacement Locking Paddle Handle for UWS Toolboxes # UWSLOCKING and it shows the cylinder when it is in the locked position. So when you install the cylinder you will want to ensure it is in that position so you can lock the handle.

  • 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...
