Description

Description of the feature you're suggesting.

Please add Support for this unknown Keeloq Format. Its a 433 MHz signal. A HCS360 transmitter is used.

I will attach Four files where each Button is pressed 10 times.

Anything else?

The remote is used to Control a car exhaust. I want to use the flipper zero as a Remote instead of the Original Remote.

Research direction
Examine the provided .sub files (four files, each button pressed 10 times) to identify the signal pattern. Compare with existing Keeloq implementations in the firmware (e.g., in /applications/subghz/protocols/). Determine the modulation, bit rate, and button codes. Then create a new protocol decoder following the existing code structure. No linked PRs or further comments from maintainers are visible yet.
