<P>PROBLEM TO BE SOLVED: To provide a key information management system of a mobile body using a remote immobilizer system, which prevents theft or unauthorized use of the mobile body even when the mobile body is placed in an environment where communication with a management center becomes impossible. <P>SOLUTION: The key information management system of the mobile body manages a key ID 32 inherent in a vehicle for the vehicle 10 so as to be updated or added through wireless communication between the vehicle 10 and the management center 13. The vehicle 10 includes a collation control device 20; and a short-distance communication device 26 making it possible to execute short-distance communication between itself and a specific mobile terminal 14. The collation control device controls permission/non-permission related to the operation of the vehicle 10 assigned to an electronic key 11, based on collation of the key ID 32 inherent in the vehicle managed by the management center 13 and stored in a storage device 31 of the vehicle 10, and a key ID 11K inherent in an electronic key for the electronic key 11 used for the vehicle 10.
