The Evolution of Car Keys

Early Mechanical Keys

Using Bluetooth Low Energy (BLE) or Near‑Field Communication (NFC), the phone can lock, unlock, and start the lorry. Some producers likewise enable the sharing of "digital key" qualifications with relative or rental services, supplying flexible access without physical tokens.
