The hidden cellar had two access points: a hinged door that weighed 500 kg (1,100 lb) which is thought to have become unusable over the years because of its weight, and a metal door, reinforced with concrete and on steel rails that weighed 300 kg (650 lb) and measured 1 m (3.3 ft) high and 60 cm (2 ft) wide. It was located behind a shelf in Fritzl's basement workshop, protected by an electronic code entered using a remote control unit. In order to reach this door, five locking basement rooms had to be crossed. To get to the area where Elisabeth and her children were held, eight doors in total needed to be unlocked, of which two doors were additionally secured by electronic locking devices.
