You are either lifting the top pins a bit too high (which isn't likely if the bottom pins drop down when you invert the lock) or you haven't quite lifted them high enough. Just give them a little tickle upwards, one after the other, and the lock should pop open.
A false set would be if the plug turned a few degrees (sometimes up to 15!) before stopping, preventing the lock from opening. I don't think that's what you are talking about?
