If I rest the fob directly touching the push-to-start, it recognizes it after about 45seconds or so.

Is there an easy way to test to see if by some coincidence I have 2 faulty fobs, or if it's a problem with the internal prox sensor? I'm trying to narrow it down, and right now all signs point to the button, but I'm not sure. Any help?

It might be the interior sensors or an immobilizer issue, as the exterior sensors are located in the doors and trunk areas. It also could be a sign of the cars battery needing to be replaced though, if it hasn't been replaced by an optima red or yellow and is the stock 2013 battery a whole slew of issues have been seen on the forum by the stock battery getting to end of its life. I can't find the post but someone was having issues getting the car to read the key and replacing the battery on the car fixed it.
