Help me identify possible tracking device found in my car

TL;DR

I found a non-OEM electronic gadget in my car. It is wired into the ignition, and contains a 435.10 MHz radio reciever, a microcontroller, and two relays. I suspect it might be a device that allows third parties to unlock the doors and start the car with a radio.

Details

I was driving my 2020 Honda Insight EX when it started to make the annoying sound of an electromechanical relay rapidly switching on and off. When I got home I looked under the dash and straight away I could see someone other than Honda had been in here. The first thing I saw was this surface-mounted switch that doesn't belong there.

Grab ffmpeg from https://www.ffmpeg.org/download.html

It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.

The most trivial operation would be converting gifs:

ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm

• -crf values can go from 4 to 63. Lower values mean better quality.
• -b:v is the maximum allowed bitrate. Higher means better quality.

Cryptographic Best Practices

Putting cryptographic primitives together is a lot like putting a jigsaw puzzle together, where all the pieces are cut exactly the same way, but there is only one correct solution. Thankfully, there are some projects out there that are working hard to make sure developers are getting it right.

The following advice comes from years of research from leading security researchers, developers, and cryptographers. This Gist was [forked from Thomas Ptacek's Gist][1] to be more readable. Additions have been added from
