Why My Key Copy Doesn't Work | GSL Discussion

Ever wondered why when you test new key copies that some don't work? Even if they look near-identical to the original, everyone's had this issue at some point and been left wondering "What's the cause as to why my key copy doesn't work?" So today, we discuss the most common cause of this problem. While automatic key cutters tend to suffer the problem discussed more than actual locksmith equipment, any kind of key cutter can become uncalibrated. Uriah Ortiz and Brian Jarboe of Guardian Safe & Lock discuss key machine calibration and demonstrate how to perform it on our most-used shop machine, the Silca Speed 044. Also, special thanks to our friends over at UHS hardware for sponsoring this video!
