   On NextDoor, someone claims a car can be unlocked by stealing the   
   signal!   
      
   I can't tell if he's talking about the fob that unlocks the door with a   
   button, or one that just being near the door unlocks the door.   
      
   Another claims this can defeated by putting the keys in a faraday cage,   
   as if the fob was transmitting all the time.  Or theyre referring to the   
   fob that doesn't require a key (what is that called?) Isn't the range of   
   that only a few feet?  Even with the smallest yard, people inside have   
   their fob farther from their car than that, but someone else claims they   
   use an amplifier. Well that's back to the battery powered fob that does   
   nothing unless you push the button.   
      
   Another says that if you used the door lock switch on the door to lock   
   the car, this can't happen, but if you use the fob to lock the door it   
   can.  I can see a possible difference in those two methods, but is it   
   actual/true?   I always lock my car with the door switch just because   
   it's easier and you can do it befoe the door is shut, but I do often   
   then use the fob to turn off the headlights without its waiting 30   
   seconds.   
      
   I don't know if someone who doesn't live in the area and is also signed   
   up can read a nextdoor thread.  Anyone know?   
      
   I would post the url but Nextdoor said there was one new post and   
   clicking on that made the thread disappear, so I search on      stealing   
   the signal     and the last hit was on the word "the"!!!  It was shown   
   in bold and the other words didn't appear.   
      
      
   Also someoene says: I can't tell from posts here how the thieves are   
   getting into the cars that are parked on the streets. However if you   
   have one of the keyless entry systems you are vulnerable to what is   
   called a "relay" attack. There are a couple of variants but the car is   
   fooled into thinking there is either your legit key nearby when it isn't   
   or your key actually is nearby and the thief intercepts the signal. In   
   other words your car can be theoretically unlocked with your keys stored   
   in your house a modest distance away or when you're walking away from   
   your car in a parking lot.   
      
   I'm not sure how often each type of breach is occurring. Just because it   
   CAN happen doesn't mean there's an epidemic. However, if I had keyless   
   entry and was parking my car on the street I would have my keys stored   
   in an RF bag or box; they're simple to make.   
      
     -- this doesn't make sense to me.
