97 BMW 740il Alarm key wont open trunk & rear windows wont go down
Hi I have a 1997 BMW 740IL that was fine until i came to unlock all the doors by pressing the unlock botton on my key twice and the sieren only sounded once unlocking only the driver and passenger side doors. It doesn't unlock the rear doors and both windows wont go down. Also you can't open the trunk from the key by pressing the the botton or the button inside the car. The only way to open the trunk is manually with the key. I checked all the fuses in the trunk and they are all good. I change the actuators for the the rear doors with good working actuators and still same problem.
