If you look at the key fob, it's one that looks like an ordinary car key.... If you have a vehicle parked up, in a random place. Possibly, a HGV type of one, looking as if workmen, no one would usually think, nothing of it...Unless they can get into a digital system, as crooks which can get into properties using a signal scanner, jammer, even steal key fob from older vehicles to reprogram, so to access houses and commercial buildings etc, as well as change signals, remotely doing so..As you can purchase signal expanders of around 900 ft.... Or "know" someone it IT / military or policing systems, who's dodgy, that could gain access into it, even an MP, that works with gangs to "access all areas", even employed in the motor trade...Moore so when stalking & threatening, playing ghosts, watching properties & using gangs in streets to monitor your whereabouts to threaten you even..Just need to "know", you telephone number for such stalking threats !! Will forward onto others ..In our case using the system or hacking via HTTPS, using even WiFi etc too. To gain a signal, you see. Doing so remotely xxx Beloud
