Do you have one or more keys on your key ring that unlock something you no longer own? (e.g. a former house or apartment, old car)
I keep a few extra keys on my key ring for putting between my fingers and whatnot
No...I don't have a single key on my keyring that I don't use frequently.
All that's on my car key ring is my car key, cabinet has some keys that serve nothing
Too many keys/too much weight on your key ring is bad for your ignition. If I know its gone I toss the key, if I'm not 100% sure I have a random key box in a cabinet.
I hate carrying keys. I have two key rings. One with six keys I use for work. The other one has my car and house key.
