Neat project. A few years ago I tried and failed to get a junkyard Toyota security ECU from a ‘96 4Runner to work for remote lock/unlock in my ‘94 Land Cruiser with an eBay key fob. I might revisit it with this approach - cheap and easy RF analysis software/hardware would have eliminated a lot of guess work … though if memory serves I think the real headache was decoding wire colors in the security harness, which were not all explicitly labeled in the manual for “security” reasons.
What approach are you going to take to try and determine the cryptographic key of your device? Is there some way to hack and “root” your gate opener controller?
I get using AI to figure out things you might not otherwise have figured out but just copy/pasting the output from AI into a blog post is not interesting to me. Take 10 minutes to humanize the output. Write the blog post and tell us how you did it, including how you used AI, how you prompted it, etc. But I don't need someone's claude transcript as the only output. Ugh
Get an rtl-sdr dongle that covers way more frequencies, install urh ( https://github.com/jopohl/urh ), and you get the full signal on RF, demodulated and you can do full analysis on it + you can do a lot of other stuff with RF with the dongle and other software (eg. track planes in the air with dump1090, listen to walkie talkies and ham radio operators, etc.)
If you buy a tx-capable sdr, ignoring the legallity issues, you can also replay that signal or modify it before replaying.
I wouldn't use this vibe coded slop that will just blow up my hardware. Unlikely to work with other chips as the author tested it with the only one he has with him.

Nice another vibe coded project and matching AI written blog. This is all getting very tiresome. There much easier ways to generally poke around RF

Meh,

Use with caution.
