I have a 2016 Pilot EX. I have been using the remote start successfully, more or less, since the beginning. Today, out of nowhere, I am unable to start the car remotely. I tried switching key fobs and going through the lock and hold-down-the-other-button process with no luck. I went to setting and turned "off" the remote start feature then turned it on again. Still.... nothing. Any suggestions? Batteries in key fob are relatively new. Thanks.
