Description

Description of the feature you're suggesting.

Wanted to add flipper to my existing remote gate setup but it looks like Gorke Electronics (PL) is using some kind of custom modification of the KeeLoq standard. Would love to see it implemented into flipper.

Anything else?

From scanning original remote I can see that the signal is 433MHz 64-bit. Not sure what kind of data is needed to develop support for Gorke devices.

Research direction
Investigate the Gorke Electronics proprietary KeeLoq variation. Start by analyzing captured 433MHz 64 bit signals from the original remote to determine the exact encoding. Review the existing KeeLoq implementation in the firmware's sub GHz module (likely in applications/subghz/protocols/). Consider reverse engineering the rolling code algorithm and consult maintainers for any additional data.
