Warrants give the government the legal right to access private materials or information. It allows them to use measures that would normally be illegal, to gain that access.
This is equally true for doors or encryption. If the government has a warrant for some data, they can attack the computing system that holds the data--just like trying to kick down a door.
They do this successfully all the time. Encryption is math in theory, but in practice it is implemented in hardware and software, neither of which are perfect. They are usually breakable.
The FBI made a big stink about forcing Apple to help them break the encryption on an iPhone. The FBI's own inspector general said that the FBI did not try hard enough to break into the phone before they went to court. And ultimately the FBI did break into that phone and access the data!
There is no need for a special law weakening encryption.
