Audi A6 engine will not turn off if the key is taken away. Introduction to car keys: A car key refers to the tool used to start/stop a vehicle. Modern car keys all use chip technology, which is a magnetic chip system. The car's ignition lock cylinder reading coil will read the chip in the key, as each chip contains fixed digital information. Introduction to remote keys: A remote key allows doors to be locked/unlocked from a distance without inserting the key into the lock. Its greatest advantage is that regardless of day or night, it enables convenient long-distance locking/unlocking without needing to locate the keyhole. The system works by emitting weak radio waves from the owner's vicinity, which are received by the car antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) executes the lock/unlock action. This system mainly consists of two parts: a transmitter and a receiver.
Don't worry, I've tested this many times with my own Audi A6. When you take the car key away, the engine won't shut off immediately. Once I threw the key to the back seat while driving and still drove several kilometers. The keyless start system in Audi is very smart - once the engine is running, it doesn't rely on the key unless you intentionally turn off the engine or the system detects a problem. The dashboard will flash a warning to remind you the key isn't in the car. If the key gets too far away (like if you walk away from the car), the vehicle might power off automatically but the engine won't suddenly stop. This design is for safety, to prevent accidental operations at high speed. I've been driving my A6 for over two years and never experienced the engine dying just because the key wasn't present.
