Leave them in your trouser pocket or handbag where you would keep them
when you weren't putting them in the ignition switch of a car that
didn't have keyless entry.

If I've got my big bunch with me, it's uncomfortable to shove them in a
pocket while driving. It sounds finicky, but after decades of getting
into a car, I automatically have the keys in my hand ready to do
something with them ...

*Automatic* keyless unlocking of doors (unless the user can disable
it, requiring a manual press of the button on the key) would seem to
be a very big hijacking risk, especially for women on their own, and
also a risk of opportunist theft from the car as the owner first
comes into range.
Mine isn't, so I don't know what the range is on keyless entry. I have
the car set for one press to unlock driver's door only, two presses for
passenger doors.
