old fuse wasn’t broken. don’t see why replacing it helped, unless the connections were dirty, but they looked clean. ideas, anyone?

Just had same problem on 2002 CX. Problem resolved. Remove key from ignition Disconnect red positive battery cable and wait 30 sec. Reconnect cable. Start the vehicle. Foot on brake. Shift into Drive. Locks should lock automatically. Shift into Park. Locks should open automatically. Try fob and lock buttons. They should all work.
