What Are Auto Keys?

An auto key is any physical or digital device that enables a chauffeur to unlock a car, disarm the immobiliser, and begin the engine.

• Standard Mechanical Key-- The easiest type; 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 vehicle's immobiliser. If the chip isn't acknowledged, the engine will not begin.
• Remote/Keyless Entry Fob-- Combines a transponder chip with RF buttons for lock/unlock functions. Many models include a "panic" alarm or trunk release.
• Smart Key-- Allows "hands‑free" entry and ignition. The fob needs to be inside the vehicle; a push‑button begins the engine. Utilizes encrypted RF and in some cases NFC.
• Digital Key-- A virtual key saved in a smartphone app. Interacts by means of Bluetooth LE or NFC, enabling the phone to replicate a smart key. Some manufacturers use restricted "share‑the‑key" functionality.

• Proximity Sensing-- Smart secrets rely on low‑frequency (LF) signals transmitted by the car. When the key is within a metre, the system unlocks doors and allows the start button.
• Encryption & & Authentication-- Digital keys utilize public‑key cryptography (e.g., AES‑256) and token‑based authentication over a safe cloud link. When any of these layers malfunction-- due to a dead battery, damaged chip, or software application problem-- the vehicle may decline to begin or open.
