          Can this lock be cut with a pair of bolt cutters?

          1 Answer | 
          Answer This Question

          Thank you for your inquiry. No it is not. Unfortunately, with the right tools and enough time, virtually any security device can be defeated. The most important function of any locking mechanism is deterrence, and we take pride in the safety deterrence our security products provide.

                  This lock was exactly what I needed for my POD for a cross country move. It was sturdy and I like the keyhole cover. I've had it about 6 weeks and it continues to work like new. Highly recommend.
                  by
                  This Master lock fit my needs perfectly. Very heavy duty padlock and a well trusted brand. With a covered shroud I won’t have to worry about snow and dirt getting in. A bonus feature is that the key cannot be removed from the lock when it is unlocked and helps prevent key loss. Two keys provided. Excellent customer service from Home Depot when there was a mix up with my online order but it was resolved quickly and smoothly.
                  by
                  Very good quality padlock set from well known Master brand. Purchased it for my locker unit to keep its contents secure. Opens and closes smoothly. When the lock is open there's no way to remove the key from it. Lock needs to be locked, in order to remove the key - a great feature! Very cost effective since the storage facility offers their own locks but for double the price!

                      Poor mechanism
                      This is the second lock that I’ve purchased that has had an issue with opening. I’m currently trying to open the lock on my storage and it’s stuck! I used lubricant and it still won’t open! I would not have bought it if my usual lock was in stock. Buy at your own risk!

                        Super Easy Pick
                        Bought this to practice lock picking, was in within less than a minute. Only have to pick one of the 4 pins. Not secure at all, there are much better options.

                          NOT weather resistant!!
                          Used this lock to keep a storage locker secure which in fairness it DID do. HOWEVER when trying to remove it, each key failed to turn it even a little and a slight jostle of the lock had water dripping freely from the lock. Be sure that if you want it to come off, you also have access to an angle grinder and a metal disc.
