Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles - CH509 - UWSLOCKCH509

Average Customer Rating:  4.9 out of 5 stars   (92 Customer Reviews)


Missing nut, had to re-use the old [crappy] one. Barrel, lock and keys work fine. Would have been 5 stars but not if it’s missing parts.

Shoot! I will send your information to our customer service team and we will get you the missing piece. Thanks for letting us know!


Great to find a quick replacement lock for my 13 year old toolbox that was otherwise in great shape. Appreciate the quick ship and affordable price.



Still works as advertised a year later


I was stunned to find the replacement lock, cylinder and keys. This was for a UWS toolbox that was on a 2001 Ford Ranger XLT that I purchased. The one that was in it would work - sometimes - but not always. The toolbox itself was in good shape but my best guess was that moisture had damaged the lock. I searched locally but could find nothing locally. I looked online and found this vendor and placed the order. It was EXTREMELY reasonable and arrived almost instantly. I am absolutely delighted! As far as I am concerned, getting parts when you need them is a service of the past. This is an exception!!!!



It is still working perfectly and without issue.


Fot like it was made for my truck Perfect fit and easy install


I initially ordered the CH508 but then found out it wouldn't be delivered in time. So I changed the order for the CH509, thinking It would fit. It was delivered quickly but the locking paddle is too short. I'm unable to use it.

Who manufactured your toolbox? If its not a UWS box, you can easily remove the paddle or latch from your existing lock and use it on the replacement. The latch is held on by one screw, and is easily swapped out.


They had the exact part I needed at a great price. Package arrived when they said it would. Very happy with my choice.


Great products


I found what I needed at a good price. It was received in a timely manner. Very pleased.

Everything is great.Holding up very well.


Great service


I have 2 trucks with 3 tool boxes on each, and a whole bunch of keys. I have always wanted the boxes to be keyed alike.'s web site is easy to navigate and order from for the replacement locks so all my boxes are now keyed alike. The locks were a perfect fit. Happy


I ordered a replacement lock cylinder for a toolbox. It was a pleasure doing business with an honorable company like etrailer and to purchase a quality product at a reasonable price and receive it in a timely fashion with no delay in shipping. I will definitely make purchases from etrailer again.


I ordered a lock core for my United welding services truck cross box. It was a great oem replacement and it went in in minutes. Shipping was easy and cheap and they stayed in contact with me to make sure I received my parts and were correct.Thank you!


I order, it arrives and is exactly what I ordered, I install it works and I move on to the next project. thanks,


Used this for my UWS truck toolbox. Works great


Perfect fit/replacement for my old lock, easy to install. Shipping was on time and great follow up from etrailer to be sure I was satisfied.


Product was very easy to find on the website. Product was exactly what I orders and shipping was fast as well. I will continue to do business with


The product is as expected and could have been purchased in other places - however, has always been dependable in terms of knowing exactly what I need, at a good price and delivered in a timely manner. Why go elsewhere ?


Was a direct replacement perfect fit. Had to remove handle assembly, drill out rivets, replace lock and rivet assembly back in place.


Received product in just a couple of days even at standard shipping. Product was just as described. Installation and function were flawless and simple. Will definitely order from etrailer again.


Bought a used toolbox, it had this lock but didnt come with a key. I bought this to get 2 keys for a cheaper price.


This was the exact lock needed for the tool box and good customer service. Would order from this company again.


Product was delivered promptly and as described. Very happy with the service and the product. I highly recommend etrailer.


The locks worked great on my tool boxes .


Still working after a year. Does what it needs to do


The locks where a perfect fit to replace the old ones on my horse trailer!

  • Replacement Lock Cylinder for a UWS Toolbox
    As long as the paddle handle on your UWS toolbox looks like the photo that I have attached, you can use the UWS Replacement Lock Cylinder, # UWSLOCKCH509. This lock comes with 2 keys. If you still have your old keys, there will be a number on them that starts with the letters CH. If you can send me the numbers on your keys, I can see if we have a lock cylinder that matches your old keys.

  • Replacement Key for CH530 Lock Cylinder
    We do not have a replacement key for the CH530 lock core so your best option is to replace the core altogether with # UWSLOCKCH509 or other key code. The replacement core will include two keys.

  • Replacement Lock Cylinder And Keys For UWS Truck Box
    The UWS truck boxes have a variety of different cylinder numbers. The replacement number should be printed on the lock core as well as on the key. If you want to keep your current keys, I recommend you get the same number. If you have the CH509 that your friend stated, then you will want the Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles - CH509 # UWSLOCKCH509. This includes one lock cylinder and 2 keys.

    The Replacement Lock Cylinder for UWS Toolboxes part # UWSLOCKCH509 is an extremely common cylinder type lock used in alot of different manufacturers boxes. Given yours is coded CH509 this should be a perfect match, When companies use different lock cores there are different letters and numbers for their type of lock.

  • Replacement Key for UWS Toolbox Latch
    On your UWS toolbox the number for the replacement key you need is printed on the lock cylinder. For example, the part # KEYCH509 is a replacement key made specifically for the UWS Toolboxes that use key code 509. This is the correct replacement key for your UWS toolbox. The KEYCH--- is the way to find your specific key number with the dashes being the number printed on the lock core. I tried to see the number in the photos and can only make out a 5. If you can't make out the number...

  • Replacement Lock and Key # CH509 for Leer Truck Cap Tool Box
    I checked with my technical contact at UWS to see if they made the truck cap tool box for Leer but I was not able to confirm that this was their OEM product. Still, it is quite likely that this part will work for you since the reference number matches exactly. To help you confirm the fit I pulled a sample from inventory and took several measurements for you. The video linked at right will show you this item and includes the measurements. Please note that part # UWSLOCKCH509 includes the...

  • Looking For Lock Cylinder 509 On T-Handle
    The only lock cylinder we have that is 509 is the Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles - CH509 # UWSLOCKCH509. We also have extra keys available. They are the Replacement Key for UWS Toolboxes - CH509 # KEYCH509. Unfortunately this won't help with a locking t-handle. The only T-handle lock we currently carry is the Camco Replacement Locking T-Handle - 2-1/4" Long x 5/16" Square Shaft # CAM44393, so you may want to consider swapping your current locks out.

  • Replacement Locks and Keys for Tool Boxes on Used Tow Truck with PK10, PK12, and PK9 Locks
    It sounds like you simply need some replacement toolbox lock cylinders keyed alike. The PK numbers you gave were for basic lock cylinders for toolboxes and even though we don't carry those specific locks or keys I do have options for you. I recommend the Replacement Lock Cylinder for UWS Toolboxes w Square Paddle Handles # UWSLOCKCH509 for example and simply selecting the quantity desired keyed the same. Some numbers are more prominent than others so the replacement prices may vary....

  • Replacement Lock for Maxx Tow Maxx Haul Trailer Tongue Toolbox
    MaxxTow unfortunately doesn't offer replacement keys. If the box is locked, your best bet would be to drill out the lock and replace it with something like # UWSLOCKCH509. You will need to remove the cam lever from the existing lock and install it on the replacement in order for the latch to line up correctly.

  • 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...
