Abstract (en)
[origin: EP0761917A1] The key has a mechanically coded part and a transponder for exchanging an identification code containing a fixed code and a second code part. The fixed code can be used with domestic door closure systems for identifying the key holder as authorised to enter. An automatic door opener can be actuated if the key holder identification is successful. The door closure system can be synchronised to the fixed code in the key. A further key can have a transponder which just contains the fixed code.
