Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles - CH501 - UWSLOCKCH501

Average Customer Rating:  4.9 out of 5 stars   (71 Customer Reviews)


I had looked for several weeks trying to locate this particular lock with the CH501 key. Now, all the locks on my truck have the same keys. Thanks for the quick shipping.

It has been working perfectly, thanks.
Nelson B - 12/09/2021


This lock went right in, it replaced an old missing key lock and fit as advertised.


Not all the parts were with the product is missing the nut called and sent the wrong size nut, waiting for a new lock cylinder

Thank you for leaving a review and for letting us know! Our customer service team should be reaching out to you in the near future.
-- Etrailer Expert Brooke M - 10/19/2021


The initial order came without an essential part, but etrailer fulfilled my request the next day and sent me a replacement with no questions asked. The part itself was a perfect fit as well!




Support has been great, love the web site and the email response was quick on a very detailed question I had. Nothing but good things to say about etrailer products and support.

We sold the truck that had the box which this lock went on, so I dont own it anymore, however, we were happy with it while we owned it.

Just what I needed.


This lock replacement was exactly what I needed and worked perfectly to replace the lock on my truck toolbox.


Same issue of extremely long shipping wait time and ship time, the product itself was good quality, though I think design wise the website should be a little more clearer when something is in stock, as i originally ordered a no longer manufactured part, and waited, like an idiot


I'll give it a 4 other than the long wait period everything else was fine products were great and in perfect condition


Thank you for your prompt service. We had ordered a new tool box and when it arrived it had a broken lock cylinder. Rather than trying to replace the lock through the supplier we found your information on the internet and within a few days we had the correct replacement lock cylinder.


I received a quality product that was a perfect replacement fit in a couple days after I ordered. I am very happy with your company.


You have to detach the whole lock latch unit to install the new lock core, but once you do, the installation of the core itself couldn't be simpler. Fits perfectly and works as promised once re-installed.

etrailer is a pleasure to buy from!


O.M.E. Lock set was what was needed to match the same key code for other storage box's. Perfect match and fit for old lock's. etrailer always has what I need in stock and is my go to source for my trailer and RV needs.


we ordered a replacement cylinder for a toolbox we bought at a garage sale and with my son going off to college he needed to be able to lock it. The fit was perfect, it was easy to figure out what to get. Also the shipping price was reasonable and it came in a very timely manner.


Exactly what I needed. 1 year later and still working great.

Still working great
Chris S - 02/28/2020


It's exactly like advertised.. I havent installed it on my truck tool box yet but most likely will this weekend


This was just what we needed. Perfect lock fit for our tool box. Good sturdy product and good price for this product. Very pleased with it.


Great product easy to install and works great .I lost the keys to my old lock and could not lock the box anymore . This worked out great for me.


Lock cylinder worked in my tool box as I hoped it would. Service was excellent.


Excellent product. Exactly what I needed. It was a plus to receive extra nuts. To be completely perfect, the bag where it came, would need to have a better presence.


The lock installed easy and is just what I need to keep thieves out of my toolbox.


Good Product, Very Good Price..


Perfect fit - fast service - great job etrailer


This was not my first order. But I have always received excellent service and quality products. Always have what I need!

  • Recommended Replacement Lock And Keys For Toolbox Square Paddle Lock
    I may have a solution for you, but we do not have a replacement key L103 for a Homak Toolbox. I recommend using a toolbox lock like the Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles - CH501 # UWSLOCKCH501 which comes with 1 lock core and 2 keys. If you have a square paddle lock, this replacement should fit.

  • Will Replacement Lock Cylinder for UWS Toolboxes Work on Delta Toolbox
    The Replacement Lock Cylinder # UWSLOCKCH501 is designed to fit UWS Toolboxes, however, we've had a few customers report that they were able to use it on their Delta toolboxes. While chances are it will work, we don't sell Delta products, so I wouldn't be able to confirm this will be a suitable replacement for all models of Delta toolboxes. In regard to your lock number, there isn't a UWS lock available with key number 1512, but since the lock sets do include a pair of keys, you can simply...

  • Replacement Locking Core and Key for Toolbox
    I do have a possible option for you but we do not carry replacement parts for Dewalt tool boxes. Instead, I recommend replacing the locking core with something like part # UWSLOCKCH501. You may need to reuse your existing latch in order for this locking core to work. I have attached a few dimensional photos to help you determine compatibility as well.

  • Will The Replacement Lock Cylinder For UWS Toolboxes Work On A Horse Trailer?
    The Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles # UWSLOCKCH501 is made by a toolbox company, but it might work if your dimensions match. This product measures .676 from under the lock head to to the end, and has a diameter .626 inches. If the measurements match, and you're not using it on a drawer slide, dog boxes, T-handles or push-button locks, you should be fine to use it.

  • Length of Catch Arm on UWS Lock Cylinder UWSLOCKCH501 and Can Lock Be Keyed Alike
    The Replacement Lock Cylinder for UWS Toolboxes with Square Paddle Handles, part # UWSLOCKCH501, you have referenced, will come with a pair of the key # CH501. If you order 6 of these locks they will all come with the # CH501 keys, so they will be keyed alike. This lock is designed for the UWS toolboxes with square paddle handles. If you only need extra keys without the lock you can order the Replacement Key for UWS Toolboxes, part # KEYCH501. The measurement from the catch arm to the...

  • How to Add Locks to a UWS Tool and Fuel Combo Tool Box
    If there is a cutout on the handle for the lock core then you can use pretty much any of our Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles like part # UWSLOCKCH501. If you wanted a specific key number then you would search "UWSLOCKCH###" with the ### being the number for the key/lock core you want. If your handle does not have a cutout for the lock core then you would need to use the Replacement Locking Paddle Handle for UWS Toolboxes part # UWSLOCKING.

  • Replacement Lock Cylinders For UWS Toolboxes
    You sure can replace the locks on your UWS toolbox and install locks so that you have the same locks on all 3 tool boxes. Just order the replacement lock cylinders with part # UWSLOCKCH502. Each of these locks come with 2 keys. If you need additional keys for the 502 locks, just order part # KEYCH502. These cylinders will not work with drawer slide, dog boxes, T-handles or push-button locks.

  • Are Replacement Keys Available for Maxxtow Toolboxes
    I do have a solution for you but we do not have a key that is going to match. What I recommend, since the box is unlocked, is to replace the lock. You can use # UWSLOCKCH501 for a replacement lock and 2 keys.

  • Latch Will Not Open Lid on UWS Tool Box
    I contacted UWS, and they gave me a couple of solutions to get your tool box to open. UWS suggested to first try to push down on the top of the lid to make sure the lid is close all the way and latch. Then turn the key to the unlock position and then pull both paddle handles to open lid. If this does not open the tool box lid, then there might be something in the box that that could be interfering with the connecting rod between the latch and the handle. They suggested parking on a downhill...

  • 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...

  • Is There A Higher Security Lock for Toolbox
    The Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles - CH501 # UWSLOCKCH501 is the only real option to keep the lid locked on your toolbox without making any type of modifications. You can keep the toolbox itself safely in your truck with the ToyLok Toolbox Mounted Retractable Cable Lock # LC337120-337117 which gets placed directly in your toolbox. While this isn't an additional lock for the lid, this does offer added safety from the toolbox being taken as well as a...

  • Fitment and Compatibility of Replacement Lock Core for Tack Room on Horse Trailer
    Thanks for your picture. The lock you were looking at is designed by a tool box company, UWS, but it might work for your latch depending on the dimensions. Best thing is to measure. The # UWSLOCKCH501 has a diameter of .626 inches and length from under the lock head to the end of .676 inches when measured with a caliper like # PTW80157. I was able to find a replacement key and tumbler set for a latch lock more like the one in your picture. This new tumbler set # CHKT fits lock models...
