The Yale Conexis L1 is a very popular rfid, bluetooth, zwave etc door lock in the UK. This video has taken ages to put together for many reasons but in it i show you how you can copy the RFID cards that come with the lock. The project isnt finished as at the moment i can replicate a key and open the door but i need to work out how the algorithm works so that i can predict the next value as well as generate my own cards.

Commands used on the proxmark

hf mf auto - to automatically copy the mifare classic card
hf mf rdbl 16 B FFFFFFFFFFFF - to read block 16 with key B
hf mf wrbl 16 B FFFFFFFFFFFF {data} - to write the data to block 16
diff -s -W 70 file1 file2 - to compare files ( useful with the json files to find out if any data changed )
