Average Customer Rating:  4.9 out of 5 stars   (73 Customer Reviews)


This lock was exactly what I needed to replace one in a used truck box. The fit was spot on based on the information I input. Works perfectly and locks up tight with no wiggle. If needed I would definitely come back to etrailer.


Needed a key and a lock. Looked around and "" had just the product I needed at a great price. Ordered it on a Friday evening and it was delivered on Monday!!!!! Talk about outstanding Customer Service! The keys work perfect in the existing lock and the replacement lock was easy to replace. Now I can secure my tool box and use the paddle handle to open it from either side. Thank you

After a year of constant use and exposure to the elements the locks are still working like new!!!!

Perfect replacement for my UWS toolbox lock!


Product worked perfect very easy to install. Definitely worth buying if u need to change locks on your toolbox


Glad to know they were still available lock has been working great


Works great as a direct replacement in a large, Dee Zee truck box.

Still working great after a year in harsh conditions. So well that I used them in two, additional Dee Zee boxes.

Bought a used tool box for my truck, and of course there was no key available. I knew the brand of the tool box, so I did a google search. I ended up finding etrailer corporation, and the amount/availability of parts was excellent. Typed in the code on the existing lock and quickly found the replacement. Install was a breeze and the lock works perfect.

Will definitely use etrailer again, I highly recommend this company.


Fast delivery was a great fit for my tool box. Installed in minutes. Now I can lock up my stuff. Thanks!


What a great experience. Had what I needed at a great price and the service/delivery speed was exceptional. The lockset fit well and worked beautifully. Thanks, etrailer! I will definitely be back and recommend the site.


Product was great, and the customer service was even better, very easy to talk to and helpful. The only thing I would say is that the lock cylinder I received was a little difficult to slide the key in and out and turn, but once I put a little graphite lubricant in it it worked like a charm!


To Etrailer corporation
Thank you
so much for the prompt delivery of my cam locks for my dump trailer battery box they fit perfectly I am a first time customer and I will be a regular customer. Thank you


It was very easy to navigate your site


Ordered this lock and key set to change my toolbox set to match my side boxes.
Took less than 5 min to install and now all boxes use the same key.
Very happy with product.


Exact lock for the make and model tool box , shipped quickly, installed in 5 minutes. Don't waste your time and money on the so-called "universal locks". Would buy again from ETRAILER.


I placed an order for some locks and it was easy. The order arrived on time and I was able to track it. The follow up email was a very nice and professional touch. I will use etrailer again.

Thank You


I purchased several of these locks so that all of my tool boxes were keyed the same and they work great


The locks were perfect, easy to install, and work wonderfully. I was also impressed because I left a message and it was actually returned for a product about $25 with taxes. Impressive. I will be using etrailer again.


This product was exactly what I was looking for. It fit my Delta toolbox perfectly and it was an excellent price. It was delivered quickly and I would definitely by from here again. Quality products and service.


The lock and the keys are working wonde rful


Great customer service. Key lock set worked perfect.
Would definitely purchase again with etrailer.


Great customer service and products


I turn this lock 20 times a day. To get to my tools. Quickly, without flaw. Thanks


Great lock - fits in my existing tool box - new key even fits the other side. Great company to order from! Good communication! Fast delivery!


Ordered new lock and key because old lock was missing the keys. I matched the key code and had quick. New key fits old lock. Would recommend


Lock fit perfectly, turns smoothly.
