Could be the Flipper Zero that Canada just banned, due to it's use in car thefts.

The flipper zero can't get around rolling codes, unless it's a very specific situation. Car thiefs aren't using them.
The OP's quote leaves out the "It is being targeted at Hyundai and Kia models." part. From what I can find those brands are (were?) susceptible to rollback where sending an old code reactivates codes that came after it

I think you would still have to wait for the owner to use their keys.
Default firmware cannot, and most cars won’t work. But specific makes have decades old security holes that still exist in new models… for reasons? And custom firmware unlocks the firmware limitations.
So technically possible, but banning the flipper doesn’t fix the security hole. It’s like banning a hammer because it can break a window. It’s now more difficult to do construction work, and crow bars still exist.
