So I've recently purchased some washers and dryers for my tenets that are coin operated. After getting them into the basement and making sure they ran ok I noticed that one of the tubular locks seems to be stuck at a half way point. I'm pretty decent at picking these types of locks because my aunt and uncle are also landlords and they've bought several of these kinds of washers and dryers and I've used the tubular lock pick to have new keys made for them as they did not come with any.
So upon further inspection it seems as if one of the pins (first one on right) is stuck. When I remove the panel and turn it upside down the pin will come out but turn it back over and it falls back in again. I've tried shaking the door upside down, using a little WD-40 and after looking around on this site I've also tried depressing and wiggling it a bit with a hairpin to get it unstuck.
Is there anyway to correct this problem or should I buy a new lock/call a locksmith? I try to do most of this stuff on my own as "specialists" seem to be quite expensive and I like being able to service my own things.
Thanks in advance if this has been asked before, I looked through the forums and found 1 post similiar to mine but not much in the way of advice.
