Honda (and any well established OEM) has rolling code on their newer models for sure. There are 2 scenarios possible here regarding this article.
1st - message is recorded while key is outside of the vehicle range.
Rolling Code does not help here since the vehicle never received the original signal from the key.
The point of rolling code is that same signal cannot be used twice to open the vehicle.
There is no protection against this with unidirectional RF keys, but requires physical access to the key and your recorded message needs to be first one sent to the vehicle.
2nd - it's fake. This I say because the key gets out of the frame in the video when the signal is replayed...
- HackingInHeart 5y agoIt is not fake, and Honda does NOT have rolling codes. This assumption is why the problem was never found. Even I assumed they had rolling codes until I performed a rolljam attack on a Honda and found that the keys NEVER expired, meaning they DO NOT ROLL.
- wallaBBB 5y agoThen do a simple video - press unlock or RES with the key in vehicle range. Record that RF Tx and then replay the message. See if it does the same operation on the vehicle. Preferably with the key not disappearing out of the frame. Dude uC used for keys come withe special sections of rolling code to have extended lifetime compared to conventional EEPROM. Same way they come with Transponder built in. P.S. And the second key in the frame as well...
- HackingInHeart 5y agoYou can also try it for yourself, but I'll gladly record a new demo soon.
- HackingInHeart 5y agoWait, second key? Not all cars have a spare (not all owners know where it is). You're being so picky. Go away, troll. The keys were on the hood in the video. That owner didn't have a spare set.
