I have another Keyfob, but thats a bit harder (than the Marantec)
Its a Clemsa MASTERCODE VM1
Its a Spanish Manufacturer.
The Keyfob sneds at 433.92MHz and semms to be a fixed Code (Dip Switches) but with a manufacturer code.
Replay Attack DIDNT work.
More infos are very hard to get.
I found a spanish compliance document and a scanned Manual in Spanish. (I do not know spanish… :D)
Apparently you can copy Key FOBs directly ( → Mando garaje clemsa MV 12 mastercode nuevo modelo - YouTube)
I have attached 4 Photos, 2 Captures from flipper (I can do SDR as well but only if needed, we dont have enough of the key FOBs at my work to take them home) and the Documents i have found online.
Its not for a high security Gate but for a simple Car barrier to our Carpark.
The Capures are a) 10x pressed, and b) one Long/hold Press, Idk if this makes a difference or sends the mastercode, but maybe it helps.
