I read the ever large manual for the car, (2009 335i Coupe) and it says to activate the panic on the remote, you just hold the trunk button down for a few seconds. Well, tried that, nothing happened. Then, I tried holding the lock button down for a few seconds (the BMW logo button) and nothing happened. And know that when you press the unlock button it will unlock and then roll the windows down and sunroof open, so that button didn't need testing for the panic. Any insights? I'm hoping to never have to need it, but then again, its always good to know just...in...case.... Thanks!
