Key fob issue - can someone help?

doogle · 09-11-2017, 06:40 PM

I am having pretty much the exact same problem.

E90 328xi (2007)

-Replaced fuses 56 and 57 with 20A
-I can lock/unlock all doors with physical key in the door
-I can lock/unlock all doors with lock button on dash
-Key fob does not lock/unlock/open trunk/activate alarm
-Key fob DOES start car
-I sent the key fob into bmwgm5.com to see if it needed to be repaired/battery replaced but he said it was working properly.

Anyone have any ideas? I only have 1 key (I bought it used, he only had 1) and the previous owner has always had this problem.

Mine still giving me issues, so would love help as well.
Anyone in the Brooklyn area that can help scan my car?

I have a similar issue on my e91, but my physical key is also not working :/ central locking from the inside is ok, and the key does start the car.

Same here I have 2011 335i vert and the key fob does not do anything! I have too open doors with metal key, but car starts when fob is inserted in ignition slot.

may seem irrelevant but how old is your car battery?

Yeah I know, car may start fine but ECU sometimes cuts or reduce power to electronics in car to save power when battery is weak. Don't use voltmeter to test battery, do a load test.

Okay so update is that my key fob does work only if I literally place the key on the rain sensor on the windshield (unlock /lock/trunk/CAS door handle , thinking maybe it could be the transmitters that maybe failed? Doing more research before I buy anything .

ICOM is not software, it's a physical hardware.

I will do my research on "Acdp".
