Sure. Not saying he's bad at lockpicking. The point is more are you an expert yourself or how do you know he's THE guy to talk to? For reference, what are the main lock picking competitions in the world and which ones has he won? Can you name them?

When I looked it up out of interest, he isn't mentioned as the world expert in actual lockpicking forums. I found a couple of other names but in any way, it makes more sense to have it tested by a group of experts than just a single person. One person may fail, but if an entire convention full of the best lockpickers can't pick your lock, that's a much better indication the lock really is unpickable.
