• and
• requesting the management server to transmit an execution key for obtaining a permission for a transition to a registration mode or an invalidation mode using a communication device other than the in-vehicle communication device in a case in which it is detected that communication is not able to be performed,
• wherein the registration mode is a mode in which an electronic key of the vehicle is registered in the in-vehicle authentication device, and
• wherein the invalidation mode is a mode in which the electronic key registered in the in-vehicle authentication device is invalidated.

A computer-readable non-transitory storage medium having a program stored thereon, the program causing a control computer of an electronic key management system assisting device including a connector that is mounted in a vehicle and is used for a connection with an in-vehicle authentication device communicating with a management server using an in-vehicle communication device to execute:

• detecting that the in-vehicle authentication device connected through the connector is not able to communicate with the management server;
• and
• requesting the management server to transmit an execution key for obtaining a permission for a transition to a registration mode or an invalidation mode using a communication device other than the in-vehicle communication device in a case in which it is detected that communication is not able to be performed,
