Except it seems there is good case law to show that in fact suspected cannot be forced to open a combination lock, as it falls under fifth amendment protection. They can, however, be compelled to provide a key if it is a key-based lock. This applies similarly to biometric-based locks.
It's hard to believe that an encryption key is any different than a combination lock in this "encryption is like a safe" metaphor.
