About a year ago, I managed to break into a combination lock suitcase (answer: it’s very easy, if time consuming) but I’ve never had a go at picking a door lock before. I wanted to know how this might be done. Lock picking is a hobby for many. There are tonnes of videos demonstrating various locks and techniques. So, I asked a lock picker what this lock is and how I might pick it. He obliged. It turns out that this is a euro-profile pin tumbler lock. They started being used about 150 years ago, are primarily found in Europe and can be picked with modern-day pick sets. And, it really doesn’t look too hard to do.
