Single-differ lock & keyed alike cylinders
With a single-differ lock, the key only locks on exactly one cylinder. Select this option if each lock cylinder is to be locked only with its corresponding key.
In the case of keyed alike cylinders, the key locks several cylinders that have the same coding. Cylinders of different construction types are possible.
This type of locking is often used in rented flats or on garage doors, for example.
Keyed alike cylinders are often used in single-family homes to lock the front door, the garage door, the letterbox and the padlock on the cellar with just one key.
Key systems
With a key system in apartment buildings, you can conveniently control access rights.
A key system consists of cylinders with different locking authorisations. Users can only open the doors to which they are authorised to access with their key.
For example, every resident of a house can open the front door and the cellar with his or her own key, but the door to his or her own flat can only be unlocked with the appropriate key. A group key can also be set up for emergencies. All doors can be opened and closed with this.
Our local ABUS partners are there to support you with advice and planning through to installation.
