A Swiss army knife. Though I don’t use it much any more, since my Leatherman is a little easier to use, and has some tools the Wenger doesn’t.
Besides keys I have a Swiss Army Midnite Manager (LED light/ballpoint pen/small blade/bottle opener/nail file/scissors)
Besides the car keys and house keys:
A little leather pouch with a snap closure which holds a few guitar picks, and a tiny replica of Thor’s hammer Mjolnir. 
Nothing but a car key, a house key, and a couple store rewards cards.
I’m a lady who doesn’t carry a purse, so I don’t have room in my “lady-sized” pockets for anything but the bare necessities.
I have a quick-release keychain with two rings, repurposed from an olive green version of this pepper spray keyring. My car fob is on its own ring, kept away from my other keys and barcode cards. It’s handy for the gym (I use a phone app to get in instead of a card) or when I get my car serviced, although it’s probably overkill for valet parking.
Used to be a Jaguar (the car brand) logo on a metal thingamajig hanging off and resting on a leather flap which I got… somewhere ? I think my dad gave it to me back when I was a teenager. The metal bit tore off its thing a million years ago, so now it’s just a nondescript green leather flap.
I like a man who’s Batman levels of prepared.
Unlike Alpha Twit, I still have my U.S. P38, had it since I was a kid. It gets used for a variety of minor tasks once in a great while, but mostly it’s there out of habit and sentiment. Ironically, it got used quiet frequently while I was actually in the army, well after the era of c-rats. There were a few times I had to explain what it was and how to use it.
Main set of house keys has a small folding knife that looks like a key & an old Schmidt’s bottle opener.
Car key has a key to the roof rack (which I consider a part of the car when it’s up there) & a bottle opener.
My main keychain has lots of keys, a safety pin (surprisingly useful, that) and two gym membership tags (I only have one subscription nowadays, but the expired one protects the barcode on the active one from damage). The car fob is detachable from the rest.
My Spyder (trike) keychain has a tiny starfish encased in resin that my bro-in-law brought back from thailand (rather tacky, but easy to recognise by touch) and a little 2-dollar flashlight for digging in the saddlebags at night.
A bottle opener from the Blue Bitch Beach Bar in Sint Maarten.
[spoiler]Why Blue Bitch?
Take your mind out of the gutter! A blue Bitch Rock is a shiny rock that can be found along the shores of the island. It was given this name by generations before us. The Blue Bitch played a significant role on our island. At the beginning of the 20th century, when local Men left the island for work, Ladies made extra money by selling Blue Bitch Rocks as gravel for mixing cement.
Ladies will go along Great Bay Harbor Shore and stack Blue Bitch rocks into a pyramid shape and sell them. However, with the introduction od a rock crusher this practice became obsolete. Our Bar is adorned by many of these shiny rocks, hence the name Blue Bitch Bar. So do you feel better about the name now?[/spoiler]

It weighs several pounds, includes six rings, five chains, and a clasp, and is functionally useless because my roommate never locks the front door, but I always keep it in my pocket anyway and am constantly adding more stuff to it.
Car key and house key. Add me to the boring list.
A library card and a store discount card - and lots of keys, some of which I can’t even remember what they are for.
I guess I should have mentioned in the OP that my house keys are in one of these. I really like it. The keys don’t jangle and, by remembering how I arranged them, it is easy to find the correct key in the dark. The company offers all manner of accessories that fit into the keysmart, but I prefer mine with just the keys.
raspy voice Smaptiiiii… Sssstatesss…
I have three.
One has my Swiss Army knife and a microfiber cleaner for my glasses.
The other has all the stupid little customer loyalty cards, a flash drive, and a multitool.
The third is just keys.
I try to travel light. My “wallet” is a card case with four cards in it, my keychain is two keys (one of my cards is a keycard for work).
And they’re skinny keys (just house and car… no key fobs back in the 90s). But after reading this thread, I want to add a bottle opener, too…
NO, must resist, stay skinny!
House keys: front door, back, garage.
Bike locks x4*
Miniature penknife with 3cm blade. When we fly, this gets replaced with a miniature flashlight. No fob.

- Yes, bike lock keys exceed the total of all other keys. Anyone else?
ETA: by the way, OP, excellent question.
