Brief Descriptions

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

When the key is within a metre, the system unlocks doors and makes it possible for the start button. Encryption & & Authentication-- Digital secrets utilize public‑key cryptography (e.g., AES‑256) and token‑based authentication over a safe and secure cloud link.
