Years ago I was learning decoding and using an aluminum tool was able to pick a 5900D. I remember specifically that was one of the ones I was able to pick super easily, along with some other locks I had around the house.

My partner has one they purchased and I wanted to show them how easy it is to pick so they will buy a new one. But i can no longer feel any notches or flats, and looked quite dumb after I confidently said how bad the lock is lol. Did master lock finally update the mechanism to hide notches? Or am I that out of practice?
