Key Fob Not Being Detected After Audio Install
 

So yesterday, I installed my Pioneer HU and my backup camera. But now my key is not being detected sometimes. If I have the key on the drivers side, it sometimes wouldn't detect and won't let me start the car. If I move the key to the center console, it will detect it.

Anyone had this problem and know a fix? Or should I take this to the dealer?

I have the 2011 with Sport/Touring.
