Euro Double Cylinder Lock - 40x40mm - Polished Chrome - Keyed to Differ

What does Keyed Alike mean?

• Keyed Alike means that all cylinders within a suite can be opened using the same key. It's commonly used in buildings with multiple offices or cupboards as only one key is needed for all locks, making it a more efficient system. On homes or domestic properties, the same key could be used to open the front and back door, meaning users only need to carry one key.

What does Keyed to Differ mean?

• Keyed to Differ means that all cylinders will have their own unique key - this is the most common and simplest keying option for cylinders as it offers maximum security.

What does Master Keyed mean?

• Master Keyed cylinders each have their own unique keys but the whole suite can be opened by one main master key. Most commonly used in schools where individuals can have their own keys but maintenance staff can still access all rooms with one master key. If ordering one of our Master Key cylinders, please note that these are supplied with differ keys and the Master Key should be ordered separately here.
