Reverse engineering an ancient wireless security keypad using RTL-SDR
You can use a similar technique to clone a garage door remote control. You simply have to record the transmission using the techniques mentioned in this post, then rebroadcast it on the same frequency.<p>Broadcasting FM is as simple as loading a Raspberry Pi up with PiFM[0]. Or, if you don't have the original remote (but are a bit more technical), you can just brute force the combination; most remotes only use a 12-bit DIP switch (4096 combinations)[1].<p>[0] <a href="https://github.com/CodyJHeiser/PiStation" rel="nofollow">https://github.com/CodyJHeiser/PiStation</a>
