Offer keying convenience for your customers without removing the cylinder from the padlock.
The security provided by "box store" locks is generally unimpressive. If people knew how bad the locks they use to secure their valuables are, they would be appalled! In this video, I address two locks that are sold as "high security," but would give a skilled thief only a few moments of pause. I bypass the Master M176 faster than you can open the lock by entering the combination. I then pick open the M930 in seconds.
