Q: When the car battery died, the radio automatically disconnected as an anti-theft measure, I don't know if this has anything to do with the key fob not working anymore.
A: you need to replace the battery in the key fob. since I don't know what a silencer is, you'll have to deal with the company... the stereo needs a code card that came with the car when it was new in order to reprogram the stereo. if you don't have this card you need your vin # and to call Acura for the code...you also need the instructions on how to program your stereo. its in your manual. don't have your manual, ask Acura for the instructions.
