In addition, to the cell phone, some places fobs just won't work. There are two locations around here where factory fobs fail to operate. One is a Home Depot (if I parked close to the store), the other is a hospital. Some type of electrical interference is causing the failure. My new fobs with the Viper work!

I do know that automotive fobs are the lowest animal on the FCC list for operating interference. In other words, a fob cannot interfere with anything, but all others may interfere with the fob.

So, if a fob works all the time, but in one or two locations, it most likely is due to the FCC.
