Seems like a solvable problem, the trivial solution is to have the dealership program multiple fobs identically.

I guess maybe not solved yet because:

- The trivial solution also means multiple cars respond to e.g. "unlock" if they are parked adjacent.

- Anything more complicated means custom electronics for a niche market.

By contrast every small town in the world has a fundi who can duplicate your physical key.
