I had a problem with my Charger FOB for remote start and lock functions. It would not work at all at home, but worked fine everywhere else. I tried disabling wi-fi and bluetooth devices as well as wireless telephones, all to no avail. At last I discovered what was causing the problem. I have one of those home indoor/outdoor temperature monitoring units, that tells you what the temp is inside and out. It has a radio unit that you have to place outside which reads the temp and broadcasts the info back inside to the main unit. As soon as I removed the radio unit from outside the front of the house and put in the back much further from the car, BINGO, suddenly the FOB and remote start worked flawlessly. So if anybody has this problem, look for devices that use radio signals like this because they just might be the problem, especially if it works everywhere except one specific location.
