If you learn a lock you can open it quickly when pressed, but most pick-resistant locks are quite troublesome to open. If you can't bump the lock or use a pick gun and the area is not secluded it may not be reasonable to pick the lock.

And I think that's the issue. It was a foreign lock they weren't familiar with so didn't have one to practice on. It was apparently easier to copy the key.
