Is this a lock you were picking a lot, and getting before, is that what makes you think you have all the pins set?
what are you using for picks, if you have been mineing brass ore from that cave with a sharp little tool, you can leave scratches on the pins, and scratches on the holes they are in, this and the tensor digging into the cylinder wall or in the case of laminated padlocks, digging into the cap lamination will change the way it picks or resists picking.
You might be able to solve this by sanding your picks. Also, a drop of oil in the lock.
Wake up and smell the Kafka!!!
