Civil forfeiture is when the getaway car is seized when you are robbing a bank.
Restitution is when you are ordered by a court to repay the victim for their losses that your criminal behavior caused. This case involved restitution, if he didn't comply with giving up the private keys he would be ordered to pay restitution.
