No key ring, just a single key to start the car. House has Biometric fingerprint door locks. Keys are so old tech. No hassles . I like the idea of keyless go card thing that Mecedes has. Neighbor had it on his CL , only thing that worked well on that POS.

 

I hate bulky key rings, so I just have my key fob, car key, store key, and house key.

 

Nothing but the key to the S. I usually don't have my house keys on me....I make my wife put those in her purse.

 

KISS - Keep it super simple

I just have the car keys (which, being an MB, is just a black plastic bit that uses IR to start up the car, i.e. no 'key') and house keys (which work on the garage door, mailbox, front door, etc... all in one).

I prefer it like this.
