The present disclosure includes a system for re-establishing a Bluetooth Low Energy (BLE) pairing PIN key to repair a secure connection between a mobile device and vehicle. The system may detect an error state, and provide a prompt to the user to determine if they wanted to intentionally remove their account. Responsive to an affirmative response from the user that the removal of the connection credentials was intentional, the system may send a revoke request to a server associated with the vehicle. Responsive to a user input that indicates that the removal of the credentials was unintentional, the vehicle may fetch an encrypted PIN seed of the BLE pairing PIN from memory or request the PIN seed from the server. The PIN seed re-establishes the secured pairing of the mobile device and the vehicle infotainment system without undergoing a new device setup procedure.
