Master no.3 gone bad
I went back and tried the locks I'd been working with and can pick them just fine. A practice lock ( 5 pins), Best practice lock (5 pins), and some other 5 pin deadbolts and mortise locks. Then I went out and bought a new no.3. No problem opened quick as it should. So now I felt better. I looked closely at the old one and noticed some marks in the keyway:
While I don't think that's what is keeping me from picking it it does make me think there's more wrong inside from my early days when I was mashing on pins. I was looking for some opinions on this lock and wondering if something similar has happened to anyone else.
