How many of you carry a 2nd copy of your car keys and fob, when you're

Spare key and fob are in my purse.

When you go out of town?

Spare key and fob are with me always.

Before I had a fob, I carried a second car key for 10 or 20 years, but I
stopped a while ago. I have a spare housekey and carkey buried in my
yard somewhere, but I've never trusted magnetic keyholders for cars. I
thought either it would fall off or someone would find it, since there
are so few good places to put it. So I carried the dupe in my pocket.

Yes, the magnetic key holder will fall off. Spare set of house
keys are buried in my yard, too, in one of those fake sprinkler
heads.
