Conventional Mechanical Key-- The easiest kind; a cut metal blade that matches the car's lock cylinder. No electronic components. Transponder Key-- Contains a passive RFID chip that interacts with the car's immobiliser. If the chip isn't acknowledged, the engine will not start.

The lorry's receiver understands which upcoming codes stand. Distance Sensing-- Smart keys rely on low‑frequency (LF) signals transmitted by the car. When the key is within a metre, the system opens doors and allows the start button. File encryption & & Authentication-- Digital keys utilize public‑key cryptography (e.g., AES‑256) and token‑based authentication over a safe cloud link.
