How To Key A Master Lock

In this video I’ll show how to make a Master lock work with an existing key. If you have a lock that a bunch of keys work with and you need to replace the lock, it’s fairly quick and easy with this system. The dumpster area in my community needed new locks to work with the keys that all the homeowners already have. Instead of buying all new locks and getting a whole bunch of new keys made, I found the Master Lock One Key system that allows med to make a lock that works with my key, essentially keying your own lock. I was super surprised just how easy it was to set the lock to my key and the lock has been in use for over a year and still works great!
