Hie im having a problem with a bmw e90 key after making a spare key the car starts but remote is not working what should i do? or what have i done wrong? used remote with same remote both keys are 315mhz

I think you need to add remotes to car friend

how do i add them i always do spare keys and remotes will automatically work. please guide me on how to add a remote for e90

Problem lives in your key mate..low quality keys always have problem with remote..I use those from xhorse or YH and they work good
