ABUSDiskus 20/70 Heavy Duty Stainless Steel Disk Padlock - Rustproof Lock with 3/8" Shackle - Made in Germany - Keyed Different

Really good lock. Purchased for my storage unit after watching the LockPickingLawyer on YouTube so I am fully aware it is not impenetrable but it is very well made and probably the average person who would want to break this would need a grinder so it is a relatively safe option for a storage unit. Never seen any sign of rust and I have used this in Florida so the material on top of the build quality are top notch. The only thing I would notice is that sometime it it a bit tricky to insert the key but I suppose that adds to the security in same ways. Some reviews complained about the price but when the cheapest lock from Walmart/Home Depot is close to $10 I would say this price for this is justified.

Use this (as well as a burly chain) to lock in my bikes and my Kuat and I feel very safe with this on. It’s so thick and would be really hard to cut through (In saying that tho I’m not a thief so don’t take my word for it) The lock is small yet very thick, compact and would be hard to cut due to its design.

Top quality, best locks to get for storage units.

Great lock. Smooth operation, but I added a drop of oil to the discs. I have opened and closed the lock a few hundred times with no issues. I think most negative reviews are from folks that do not understand disc cores and are only familiar with pin locks (cheap door/padlocks). Disc cores can sometimes need some key manipulation to align the discs and fully insert the key. This lock may not be for someone who will not spend 2 seconds to properly insert the key before forcing it open... breaking the key.

Needed a new storage lock and after doing some research online, this lock kept coming up as a top choice. Found this listing on Amazon and it arrived very quickly, so we were able to use it the following evening. This timeline helped immensely! As for using it: it's durable and has been working well! Super easy to use, and we feel secure in using it. So far so good!

Build is secure. Has survived a year with constant rain outdoors with only minimal corrosion but the key is finicky sometimes and doesn’t want to turn unless you have the right amount of pressure pushing into the lock cylinder

***Update: After 2 weeks of waiting, I got sent a new lock and keys directly from ABUS and everything works great now!I ordered one of these for a storage unit and they do come with two keys that are keyed to specific number by ABUS. Both of these factory keys work great with the lock and I have had no issues there.The issue comes with trying to order spare keys from ABUS. I registered the lock on ABUS' website not long after I received the product and I wanted to order two spare keys for it, so they ask to punch in the number that is on the card attached to the keys. I do that, pay for my keys, and a week later I received two new keys that look identical to the factory keys that shipped with the lock and NEITHER WILL OPEN THE LOCK. Both with go in completely and start to turn the internal mechanism but they will not fully turn to open the lock.I emailed ABUS and provided pictures of the serial on the back of my lock, and pictures of the security key number that were attached to the keys and I said "Im not sure if I accidently got the wrong spare keys shipped for what happened" and asked about the possibility of reordering spare keys. I get no response from ABUS for a week but magically two more keys from them were shipped to me (for free, thankfully) and I received them two days ago: THOSE DIDNT WORK EITHER!I am currently waiting on a response from ABUS to see if I can take one of the originals anywhere and have spares directly copied since I must have gotten the wrong key code mailed with the original keys. I will update with any other info. or I might just return this lock and look elsewhere.

It is smaller than the Master Lock and seems sturdier since it is heavier or just as heavy. It fits budget rental trucks just fine but you wont be able to use the 2nd latch. This is no problem at all. I rented a 12’ truck and used this disk lock across 4 states (10hr dr) and i had no issue at all.It comes with a card that will allow the owner to duplicate the key so makensure you keep that in a safe place or take a photo of it on your mobile.This abus 20/70 also fits storage unit doors perfectly. I use two locks on my unit just for a little extra security.
