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.
