I like to keep it light. Key and small key ring for my car key. For my new 3, one of BMW's made in Germany M keyrings. I also keep my house key in the car when out and about. I only really use valet type keyrings I use high security locks throughout the house and the one key is coded to them all. Padlocks too. One key makes things very simple! Wallet is a very light affair also.
