Abstract

PURPOSE:To make a key so as to avoid it from getting unkeepable even if a storer, storing a number of keys for rooms in a building, goes wrong. CONSTITUTION:Two sparestorers 4, 6 are installed there in addition to those of regular storers 3 to 5. If collating code of a magnetic card insetred into a collator 2 accords with another collating code to be conformed to the storer 3, by way of expample, a locking signal of this storer 3 comes off and a door 3a opens. Even if the door 3a is unlocked and the specified time elapses, this door 10a is not opend, it is so judged that the storer 3 gets out of order, and subsequently the spare storer 6 is regarded as the storer 3, controlling it, and it is used instead.
