This is a Github repository devoted to delivering to you the necessary and required tools and hardware to perform Samy Kamkar's RollJam attack.

This is for educational purposes only. I am in NO WAY liable for any actions executed by means of the contents within this repository. PLEASE use responsibly.

• Raspberry Pi (3B+ reccomended)

• YARD Stick One (With ANT500 Telescopic antenna, reccomended)

• SDR Dongle (Only necessary for finding the frequency of target; Without it, you can do a plate lookup and find the fob frequency online)

• Install Raspbian on your Raspberry Pi

• Install Rpitx on your Raspberry Pi

• Install RfCat on your machine (it should be a portable laptop)

Make sure you have a wire attatched to the GPIO pin of your Raspberry Pi to act as an antenna.

"cd" into your Rpitx folder and run:

sudo ./sendiq -i /dev/stdin -s 96000 -f <frequency> -t float

Set your jamming frequency to be slightly higher or lower than the listening frequency.

Run replay.py (Credit to AndrewMohawk and their RfCatHelpers repository) to listen for the unexpired key:

python replay.py -f <frequency> -n <number of keys to collect>

Once the key(s) are captured, you may stop jamming.

You now have an unexpired key to use on the target!
