I was just snooping on one of the Gasbuddy sites. Someone has a post about people hacking the signal from SKS fobs to steal cars. Here's the link http://www.leftlanenews.com/2006/05/03/gon...-to-steal-cars/ Anyone heard of this with the Prius???
There was a post about this before. A professor at Johns Hopkins University successfully unlocked a TI-RFID equipped car. http://rfidanalysis.org/ Reason being that the TI-RFID systems uses 40-bit long crypto key. With today’s computing speed, that takes relatively short time to crack the code. The TI-RFID system is used on late model Toyotas, including the Prius I assumed.

there was also an article in wired last year that said that the security of the SKS was far superior than any other vehicle protection system available. Someone would need to be within 15 ft of your fob with the right equipment as the code was passed to steal it. But yea, if your really paranoid and really think this is a big risk then call Toyota.

Dont garage door openers have a 'rolling code' these days so that the code could not be recorded and transmitted? It would seem to me that this would be the way to go with SKS, with a little thought put into the programming of the FOBs.
The SKS doesn't pass the same code each time, so even stealing the code with a radio device won't let you steal a Prius. It's much like the rolling code on some garage door openers, but even more sophisticated. You would need to mount a brute force attack using very large amounts of computer power, which takes a large amount of time. If someone wants to steal your Prius, it's going to be much easier to just tow it. Tom
