2005 volvo s40 remote start

I just installed an audioox APS687 using a 556u in a 2005 Volvo S40.  The install went smoothly.  I reccommend using a cambus adapter to do locks, arm, disarm, trunk and tach because it is very hard to get through the door jam into the vehicle.  The only problem is that when you install the factory cosmetic trim panel over the key cylinder it must block the 556u signal because it says key error when remote starting.  Does anyone have any ideas.  Also after vacuuming the car for the customer the air bag triggered.  The customer stated that this is a factory defect with sensors under the seats and happens all the time.  So please be aware of this problem.  The airbag can only be reset by the dealer.     Hope this post can help out some.Speed of Sound Technologies
