Even today, almost every car has at least one key cylinder in the driver’s door, although it is rarely used. Its existence is justified by a possible voltage drop of the vehicle battery or the key fob. This is because the physical key bit, which is often integrated into the remote control, is then used to access the car. The Kiekert reactiWAKE system ensures access entirely without a key cylinder or physical key. With reactiWAKE, the backup solution is completely digital.
