from the other key what i have remote working normal.
is there a way that can active remote to working again?
or is key damage?

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.
