Sorry for the necro but:
Has anyone heard of a Pioneer AVIC-Z140BH causing interference? Electrical bonanza!
Long story short: Was having weird key detection issues. Turns out that my "module" under the console wasn't plugged in properly. Dealership found the problem and reconnected the module. Car was fine so they parked it. I showed up 3 hrs later and the antenna is *completely* dead. I can't open the doors from outside the car without the physical key. Key fob is not detected anywhere inside the car except for inside the fobgina.
Any way to reset the module or am I just boned?
