For many decades, the ignition key was solid, similar to ordinary door keys. This design format, however, began changing in the late 20th century. For a start, the key included an immobiliser – an electronic device that made it impossible to start the engine with an incorrect key. The first ŠKODA to feature an immobiliser was the FELICIA in 1994. The next stage was remote-controlled central locking, which meant that a key no longer had to be physically inserted in the door to unlock the car, and 1999 saw the first ŠKODA with a foldable key – the FABIA from the 2000 model year. All these features are on display at the ŠKODA MUSEUM, e.g. in the YETI.
