subGhz: Keeloq: DTM System - remote protocol request

[AABatteries]

Description of the feature you're suggesting.

I'm hoping that somebody can add support for DTM System (Keeloq based) protocol - I know DTM Neo protocol is already implemented but this seems to be a different protocol - maybe very similar so easy to add? The transmission frequency is 433,868 MHz with AM modulation

I would love to be able to bind my gate remote with this protocol, finally I would have all of my remotes in my Flipper! Thanks a lot!

@AABatteries it's a little bit more complicated, we need this system in our office to figure out what kind of keeloq learning scheme used and if it got static manufacture key.

@Skorpionm can you guide @AABatteries throw the process?

[Skorpionm]

To add this protocol you need to know the manufacture key. it can be obtained by analyzing the HCS301 power traces during encryption. To do this I need this remote control. but since this protocol has several encoding methods, it is not at all a fact that the manufacture key that is in this remote control will fit the rest of the remote controls in this line, as happened here https://github.com/flipperdevices/flipperzero-firmware/issues/3085

I can’t help but encrypt by records
