Ford pats key not detected

[lush29]

Hi all, have an 2007 ford focus 1.6 petrol. Fault on the dash pats key not detected. The car is starting with the key inserted but is not starting keyless. We try to program the keys and new key but is not working. I been checking the 2 fuses in gem they are ok. Faults in IC u1900 can bus fault receive error b902. RKE fault b1091 passive key programing error. Anyone familiar with this? Thanks
