Dog swallows RFID, starts car

A woman in Surrey, England couldn't figure out why her car wouldn't start. An Automobile Association patrolman arrived on the scene and the two realized that the woman's dog had swallowed the car's immobilizer chip fob. The immobilizer contains an RFID chip that must be within a certain proximity of the steering column for the key to work. According to a BBC News report, the patrolman put the dog in the front seat, turned the key, and the car started right up.
