Short Descriptions
Traditional Mechanical Key-- The simplest kind; a cut metal blade that matches the car's lock cylinder. No electronic components. Transponder Key-- Contains a passive RFID chip that communicates with the lorry's immobiliser. If the chip isn't identified, the engine will not begin.

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