What to do if the Winkhaus Security System cylinder cannot be locked?
- SStephanie WhiteAug 3, 2025
If the Winkhaus Security System cylinder cannot be locked, it could be due to several reasons. First, the battery in the cylinder might be flat, requiring a replacement. You might need to lock the cylinder with internal or external power function in an active key, or use the master key. Another reason might be that the key has no locking authorization, in which case you should ask the administrator for the corresponding authorizations. In rare cases, the electronics or the mechanical system in the cylinder could be defective, requiring you to contact a specialist company.
