Bypassing Rolling Code Systems

This blog post will discuss the implementation of Codegrabbing / RollJam, just one method of attacking AM/OOK systems that implement rolling codes (such as keeloq) — these systems are commonly found on modern vehicles and entry systems such as gates and garages. This technique has been used and spoken about for a number of years…


Hacking fixed key remotes

Previously I discussed using my RTL-SDR to merely listen for analog audio signals. In this entry I’ll discuss using it to decode digital signals (this example on fixed remote signals often used for garages / gates ) so that they can be replayed/brute forced with something like the RFCat project (based on TI’s CC1111EMK module)….
