Abstract: A vehicle key monitoring system using a keychain device is provided. The system comprises a location database and a vehicle key monitor (VKM) device, which comprises a processor and memory and is connected to the location database. The VKM receives, from a location transmitter, a keychain location identifier and stores it in the location database. The VKM compares the location identifier to a plurality of location identifiers comprising an authorized zone for the keychain. The VKM transmits the current location to a client operated by a vehicle owner. The VKM determines that the keychain device location does not match the plurality of location identifiers for the authorized zone. The VKM generates an alert indicating that the keychain device is outside its authorized location zone. The VKM transmits the alert to the client, causing the client to display the alert and the current location of the keychain.

Abstract: A client device for monitoring a physical location of keys for a vehicle using a keychain device attached to keys is provided. The client device comprises a processor and memory and communicates with a vehicle key monitor (VKM) server device. The client device receives a current keychain device location, including a first location identifier, wherein the first location identifier is not in a plurality of location identifiers comprising an authorized zone for the keychain device. The client device receives alerts indicating that the keychain device is outside the authorized location zone. The client device processes the current location of the keychain device, including reassigning values of location variables in memory to equate to the current keychain device location received from the VKM. Based on the reassignment, the client device updates map and text views to display the current location of the keychain device, and associated alerts.
