Need help with American series 260 and 200 padlocks
They all open and work well except the series 260 padlock for which the key will not turn.
I tried soaking it in penetrating oil for a number of days, tried WD-40, sprayed inside with lock saver, cleaned with brake kleen etc to no avail. I tried rapping the side of the lock as I turned the key as I did on the series 200 lock mentioned below but this did not work on this lock.
I have a series 200 padlock, a smaller version of this lock which was also stuck but after soaking it and then rapping it on the side many times as I tried to turn the key, the key slowly but surely turned and I was able to open the lock, It opens fairly smoothly now but I wanted to dis mantle it and clean the insides. The problem with this idea is that the screw inside the shackle hole will not turn no matter what I tried and I don’t want to strip the head of the phillips screw.
I need some help in figuring out what my next steps should be to rectify both these situations.
I have added photos of the series 260 padlock.
Thanks in advance
