You don't have to surrender the key, but you are required to at least decrypt things for the authorities.
However, I the twist seems to be in the word "susceptible": any encryption key is susceptible to be somehow used to commit a crime, while on the other hand a jury would probably "deny a request" of the authorities if they can't show enough evidences.
