What is a Yale 850 ? Is that a deadbolt, night latch, or padlock? and where are you from? If we offer advice geared for someone in the US but the person asking is in Australia, then that's not gonna help them much.
Please upload a pic of the lock to imgur.com and paste the link here, including a clear view of the keyway. That will help us help you.
What are you using to pick it? are you a hobbyist or just a person who needs a key for 1 lock? If you want a key made you would have to be able to remove the cylinder, does this lock allow for that?
Thanks
