I work for a company of under 100 employees in a small city. Our head IT guy bought a Flipper Zero with his own money so he could make sure our building key fobs couldn't be easily copied.

If this guy can do it, I think the bajillion dollar auto industry can figure out a solution!

Absolutely. I bet it's just easier and cheaper for them to not bother securing their fob radio.

To be clear, I'm saying they should get their shit together as a company, because it's clearly not a hard thing to fix.

If it happens to me more I may have to do the same

That there's something inherently special about me that makes me able to program....

... Yes...patience and interest.
