HomeMatic KeyMatic HM-Sec-Key Bedienungsanleitung Seite 37

Insert the key into the lock cylinder, unlock the lock and turn the key to neutral
position (where it can be pulled out). Guide the door lock drive over the key; push
it completely onto the base fastener. Fasten the door lock drive with the two Allen
screws (M3 * 14 mm) that were screwed out in the beginning of the procedure.
Screw the Allen screws in completely using the supplied Allen key; careful not to
turn too tight.
Tighten the screws "hand-tight" only, since otherwise the drive can be tilted,
which could cause faulty functionality (such as e.g.: opening the door from
the outside with the key becomes difficult).
Open the door. This is required so that the door lock drive can detect the end stop of
the lock without any hindrance during the following initialization action.
