"Learn how to cut keys and become a locksmith. You can charge a small fortune to people who lock themselves out of places. Only downside is you have to be rather reactive to any calls you get"

this is op here, good idea, but dont u need some serious skill for that? im actually pretty good at cutting keys, having quite a bit of basic experience, but as i understand it locksmithing is a pretty serious trade. but i guess i could do just basic stuff?
