Lock came 2 days after my move, despite me clearly stating that I was purchasing the lock and storage unit for my move on October 26, 2018. I’m so disappointed.

Nikki C.

I did not need this item and tried to return it with receipt in store. The clerk did not know how to return online orders. Ordered from U-Haul so I could return items and now uhaul doesn’t know how to return them.

can the U-Fortify Heavy Duty Disc Padlock 2-3/4" be cut/broken with a bolt cutter

–Yolanda Harper 11/17/2013 11:45:38 PM

The advantage of disc locks is that on a storage door/ rear door application, the shackle of the lock is not exposed. Therefore, it cannot be cut with bolt cutters.

–Stephen 11/19/2013 8:10:47 AM

Will this lock work on the back of a Uhaul truck?

–Joe 3/13/2014 5:50:27 AM

Yes, the U-Haul disc lock will work on the back of a U-Haul truck.

–Stephen 3/13/2014 9:38:09 AM

purchased one of these for a storage unit back in november. went to the storage unit again the other day and cant get the lock to open. the key fits in, it just wont turn at all. how do you get this opened?

–K White 7/18/2014 1:12:28 PM

Our moving supplies program manager writes: "Unfortunately we do not have replacement keys. Please contact the storage operator and have them cut the lock off."

–Ronald 7/23/2014 8:50:07 AM

I lost one of the two keys for my discus lock. Can I get a replacement? Locksmiths do not have any blanks that are the same.

–Ruth Goran 7/27/2014 1:13:46 PM

Sorry. Our vendor does not make replacement keys available to us on our locks.

–Ronald 7/28/2014 8:18:37 AM

I lost the keys so can I take it off with a grinder

–trace 8/21/2014 10:39:52 AM

We do not suggest using a grinder.

–Ronald 8/21/2014 12:08:34 PM

Will this lock work on a locker at a gym? I've had problems with my lock getting cut off my locker.

–Mimi 1/26/2015 2:48:55 PM

It would depend on the size of the hole in the latch on the locker.

–Ronald 1/27/2015 12:20:37 PM

I lost my keys. I know replacements aren't offered. How could I get in my storage?

–G. Mejia 2/22/2015 9:26:19 AM

Please check with the General Manager of the UHaul storage location. If your storage unit is not a UHaul storage unit, I would suggest you check with the owner of the facility.

–Ronald 2/24/2015 10:29:18 AM

I want to use this lock on my gate outside. Will this lock rust?

–Diane 3/21/2015 5:44:40 PM

Diane, because the lock is made of stainless steel it will not readily rust as ordinary steel does. However, it is not fully rust-proof in low-oxygen or high-salinity environments. Thank you.

–Joseph 3/26/2015 9:03:28 AM

My shipping container supposedly accepts any lock "as long as the shackle is 1/2." I'm not sure what that means! Will this lock due? Is the shackle 1/2"?

–MKroeger 5/2/2015 6:22:46 PM

The shackle height of a lock is the distance between the the padlock shackle (rounded bar) and lock casing.

Our disc lock has a shackle height of 3/8" (10 mm) so it will be too small for your shipping container. We have a variety of other locks that will fit your needs here.

–Joseph 5/5/2015 5:18:53 PM

Several posters below said the lock does not fit the uhaul they rented--how can I be guaranteed that this will fit the truck?

–Amanda 5/27/2015 8:47:03 AM

This lock does indeed fit all U-Haul trucks!

We have added a video to this page displaying how to properly attach this lock to the back of any U-Haul truck.

–Joseph 5/27/2015 8:59:47 AM

What is the warranty? I bought this lock to put in my storage unit and a couple weeks later it would not open. The key goes in, turns, and opens slightly, but will not open enough to get the lock off. I'm still currently Locked out of my unit.

–Steven 6/27/2015 2:35:36 PM

Assuming you are storing at a U-Haul Storage location, go into the store and explain the situation to the store's General Manager. They will help you with the lock and give you a new lock for free.

–TIMOTHY 4/24/2017 8:43:44 AM
