I can see the tips of the keypins barely into the keyway.
I have soaked it in WD for a week and have wrapped on it every few days with a rubber mallet to not damage the surface of the lock
Pin 1 still will not move up or down, pins 2, 3 and 4 are now able to be pushed up but will not drop down more than a tiny bit into the keyway.
Are these locks vulnerable to oversetting the keypins into the bible like in a comb pick attack? it might be easier to try and get the pins up instead of down.
Any ideas on how to free up the pins besides just soaking?
I'd like to get this lock functional
