I was talking to some folks recently about signals relayed by garage door openers & car remotes and the topic turned to criminals pirating the signal and stealing/robbing the owners. I have heard of capturing garage door opener signals, but not car remotes. Has anyone here ever been victimized by a “signal pirate”? Is it BS??? Comments?

Actually there is an issue with signal pirates out of Brazil making signal gear that pirates a satellite channel used for communications. |
| capturing garage door opener and car alarm codes was actually going on several years ago, but the remote makers came up with schemes that used multiple codes that were much more difficult to capture. I am sure that there are hardcore thieves that can still do it, but it is a fairly tough job these days, and requires much more expensive equipment to do it. |

I was really thinking about how this might enable car thieves. Since some of the high end cars use some kind of proximity switch instead of a traditional key in the ignition, would this make it easier to steal the vehicle??? |

I think it would be much harder with the car thief scenario. Most keys now have an RFID chip built in. The reader for this chip is very low power and I doubt a thief could capture it unless they were in your passenger seat with a scanner or maybe a dishonest valet scanning your keys directly. |

david beckham had his bmw x5 stolen like 3 times at one of his fancy european homes because his key transmitter signal was stolen Boo fucking Hoo. He can afford 300 more. I had my cell phone # stolen (many years ago) and got a $5,000.00 bill. Now that was actually funny. |

A good RFID stealing device can steal the signal from about 2ft +/- and can be as subtle as a very good pickpocket. The antenna is only about 3 in across and the device is about the size of a small external drive. |

# Both the transmitter and the receiver use the same pseudo-random number generator. When the transmitter sends a 40-bit code, it uses the pseudo-random number generator to pick a new code, which it stores in memory. On the other end, when the receiver receives a valid code, it uses the same pseudo-random number generator to pick a new one. In this way, the transmitter and the receiver are synchronized. The receiver only opens the door if it receives the code it expects.
# If you are a mile away from your car and accidentally push the button on the transmitter, the transmitter and receiver are no longer synchronized. The receiver solves this problem by accepting any of the next 256 possible valid codes in the pseudo-random number sequence. This way, you (or your three-year-old child) could "accidentally" push a button on the transmitter up to 256 times and it would be okay –– the receiver would still accept the transmission and perform the requested function. However, if you accidentally push the button 257 times, the receiver will totally ignore your transmitter. It won't work anymore. It isn't enough to capture the code, it's a rotating code. A new one is generated and the old one is invalid. |

Years ago, we tinkered around with things like that. When in the military we had some cool devices too. I work with .gov electronics now that will do some amazing stuff. The current crop is much more difficult to pin down... but, can be breached. Where there is a will, there is a way. Also, the proper equipment helps. |

Now that was actually funny. just saying it can be done. 5k phonebill sucks ass. my friend's brother racked up a bill about that big back in high school calling some chick in california. like two months in a row. |
