Question About Ace II Tubular Lock

[jimb]

I have recently started picking this lock after finding an old bank bag in one of my file cabinets.

After picking it back to the locked position after I was done with it yesterday I noticed that one pin is now stuck. It won’t push down at all but the other 6 pins are still springy.

I can't find the key to see if it still works and when I ask my wife where the key is she says it's around here somewhere.

Got any ideas of what could have happened? I'm not done playing with it yet.

Maybe youve turned the lock to a differasnt place that you thought and the pin has gone down the hole that is beneath the pip part normally or you have damaged a spring.

Ive seen it happen on worn locks and just used a magnet to pull the pin back out to continue picking but as for the sure fire problem im not entirely posative myself.
