I found a BMW key near Serra street & El Camino intersection. It looks of older BMW car (has BMW logo on it), its a very simple key , no auto lock on it but still looks big for a bicycle lock key, has no key chain, black colored. It has few characters written on both sides . If you feel its yours, please let me know the characters written on the key/ other identification. I will return the key to Stanford P&TS in 1-2 days when I get time if nobody claims it.
