have use the 868Mhz keyless option.
then i renew key again with HexTag with option BMW pfc9745 and cant program key to car no more.
keep getting error by programming.
then get a Original key from a other mini R56 and renew it under option BMW pcf9745 and again cant program key to car.
get same erro as by other key.
looks like AH dont renew the keys oke
