I've been lurking on these forums for a little while now. I've recently started picking as a hobby. So I've only been picking padlocks, and had varying rates of success. So I decide to pick the Schlage deadbolt on my back door. It's old. Really old. So I pick it successfully in about 30 seconds, which is about the fastest I've done thus far. So I try to use my key afterwards, and it won't quite go in all the way. I can still use the lock from the inside but not from the outside. It isn't too big an issue as it's due to be replaced anyway, but I'd really like to know how to sold this problem for the future.
I'm not sure on the model of the lock, I don't really know how to tell.

Thanks,
Jimmy Gizmo
PS I'm not exactly sure which forum this should be in but I figure it's a lock so ...
