- Scan an already-authenticated key card or key fob on the key reader behind the cup holders on the top of the center console.
- When the mobile app indicates that the pairing was successful, touch Done . The key list on the touchscreen (Controls > Locks) displays the new phone key. The name of the phone key is determined by the name used in the phone's settings.
