Review: Awesome lock! - Heavy duty lock. Made with quality metal for high performance. I use it on an outdoor storage unit in WI and it has held up to two years of rain, snow, and whatever else. Locking mechanism works as well now as when I first put it on. I did notice some scratches on it last I went to my unit. I guess someone tried to cut it off and couldn’t. Definitely recommend this lock to keep your things safe.
Review: Good locks - These are great locks I use them a lot

## Questions & Answers

**Q: Looking to by 2 of these, Can these be keyed alike?**
A: Hello. Please consider this item instead.  M40XT (#B00STZXWL2) Slightly smaller discus lock, but two keyed alike.

**Q: Is the opening wide enough to fit a penske moving truck?**
A: Yes

**Q: I need 6 of these keyed the same how can I do that? I don’t want the smaller version?**
A: IF you MUST have the larger version, your only option is to go to your local Locksmith Shop and order them through the locksmith.
IF you can use the smalller version, then go to your local Home Depot.  Look at the packages of pairs of these.  Compare the key  code sticker on the back of the package and gett 3 packages with the same key code - they will be keyed alike.  It will usually be MUCH cheaper than ordering through a locksmith shop.  I do this all the time.

**Q: Material:  Plastic ???  In 2 places it lists plastic as the material, not metal.**
A: No.  No.  All metal....a plastic cover that covers the key opening to keep dirt out.... the cover slides out of the way to unlock the lock.

Really heavy duty and solid which is what was needed for my situation. Bigger than expected but worked fine for my purposes. Not the cheapest thing but if you need to protect your possessions, you cannot go wrong with this.
