The best way to start is to visit some kind of workshop. There are people who are very sensitve and can lear lockpicking on their own and without any help.

If there is no lockpicking group or workshop you can use YouTube.

There are hundreds of very good lockpicking videos you can use. Look for the channels from Bosnianbill, Lockpickinglawyer or LockNoob.

They even have tutorials especially for beginners to avoid mistakes often made when you start lockpicking for the first time.
