I've noticed that if I have my cell phone with me and have WiFi on the IA range drops drastically (I'll need to be almost leaning against the door for the IA to open the door(s)). The bi-directional remote for the remote start hasn't helped much either.
Is this happening with both keys?
Coincidence. The IA system works by noticing changes in electromagnetic density. It's not that the system doesn't recognize the remote being close, it's that it's not recognizing his hand being in the handle. The field for that sensor is very narrow and wouldn't be affected by your cellphone at all.
