What is the name of this plastic piece?

It's not possible for me to leave the keys in the ignition. When I hit second gear, the car jumps so hard, the keys can't keep up; I have to go look for them somewhere in the back.
And I can't lock myself out, cuz the vent window lock is broke. Never mind that it is a hardtop, and any 7 year old kid can stick his arm in there if he wanted to, and pop the plunger up . I even made it easier for the bad guys by installing these huge dice thingies on the door-lock plunger, that my young daughter bought me for my birthday one year. I think that was 2001 or maybe 2002. They are still on there,lol.
Yeah, Leroy, I have locked my keys in other cars, but since I got married, there is always a second set nearby. That was 41 plus years ago,lol. My wife lugs a suitcase around that she somehow still calls a purse,bless her soul. When she parks that tank in the house, it takes 20 minutes for her back to straighten out.
