My 2014 Mazda 3 stopped detecting my Key FOBS. The battery in my car is new and the temp is above freezing. The Key FOBS have new batteries. When I step on the brake the ignition light turns green so I know it is not the brake switch. Neither key FOB will lock or unlcuk the doors and the car gives me a signal that it does not detect the key. I have had several moments lately where the car would just stopped detecting the key while driving but then would see the key again a few miles down the road. This leads me to beleive there is a censor gone bad somewhere in the car. Any ideas on what I can change out to fix this.

Thanks!!

 

Get it scanned for fault codes.
