Each key ring has one key on it. The remote for the car is built into the key. The only reason each key has a ring on it is so I can hang it up.
The house has those combination lock deadbolts so I don’t even need to carry a house key around.
I used to have multiple key-rings with keys to all the cars, house keys, keys to houses I no longer owned, keys to houses of neighbors who moved away a decade ago, pocket knives, multi-tools, and decorative doo dads. Then one day I couldn’t find my keys grabbed the valet key for a car out of an envelope we kept it in and had an epiphany.
Only the keys and a tiny Swiss army knife that I carry just for the bad-boy image. Every time I fly I have to check my key ring in my luggage because otherwise I am a very dangerous man. I like that feeling.
I suppose I must be the only one here that does not carry keys around. We have a driver that handles transportation and a guard ( unarmed ) that watches the house so it is never locked.
The only time we use keys is if we head back to the US for home leave.
