Mine too! But only because the battery on my fob died and I am too poor now to replace it. Frankly I kinda like it that way, it makes me more conscious or the damn fob (I used to just drop it anywhere in the car).I have a Tucson 2011 FWIW
The battery is like $1 on eBay
It’s a 2032. Just snag one from an ewaste computer motherboard. Dollar stores usually have 3 for $1.

My BMW did not come with such a fob slot but still required you to dig the key out to press the (un)lock buttons. Weird transition.
But that's the perfect fob! I keep it in my pocket and it has enough of a distinct shape I can press the buttons from the outside of the pocket. So I lock/unlock and open the trunk with no effort and yet am imune to this attack because a button press is always required. People I've driven were mistified how I was operating things because it's become so second nature you can hardly tell.
BMW late 2000s were like this. Maybe still are.
I have a 2007 BMW. It does have a slot to insert the fob. But it is not required to start or run the car. The slot acts as a charger and holder for the fob. But proximity is all that is actually needed.
Sounds like you've got the comfort access package on your car. Without that tech package (sadly not offered on my make and model year) you've got to actually put the fob into the slot to make the push to start work.
I had a 2011 3-series that required the fob to go into the slot to power or start the car.
