In news that will surprise virtually no one, tolerances on basic Master padlocks are so wide that you can use half cuts to make a tryout key set of 256 keys that will have a key to open any 4-pin Master padlock. But… I struggle to see the actual utility of making and having such a tryout key set. Most 4-pin Master padlocks are trivially raked, bumped, or picked, or Lishi-ed if M1, so short of long term persistent access to such a padlock I just don’t see it being worth the time making the set 🤷‍♂️ #locks #lockpicking #master #pentesting #security #padlocks
