Scrap Yards!
I asked in the chat and searched and had no hits, so I figured I'd post here. Hopefully its the correct place!
I've been letting some close friends know that if they need any help getting into anything they've lost keys to that I would help them.
I've been trying to learn for awhile now but don't have many training aids. So today I came up with an idea.
If I wanted to learn a bit on re-keying vehicle locks, removing them without damage that I would try my local scrap yard.
Parts are cheap and on some of the wrecked doors they don't mind giving away the locks.
Great learning experience and a great deal on parts!
Hope this helps!
