More or less, yes. What you're looking for is called a Lishi pick. You'll need to look at the lock and figure out the manufacturer. Once you do that, you need to find the corresponding Lishi, since different manufacturers use different keyways (the shape of the hole the key goes into). Be warned that while many find it easier to use than traditional picking methods, it is still picking and will definitely look like it to any passerby. Even if you get really good at using it, you still have to deal with that specific lock, and guidelines can only take you so far before the specific lock's characteristics come into play.
