What is a key plan?
A key plan is an overview of which key can open which door. It belongs to keyed-alike cylinders: one key fits several locks, and not every key fits everywhere.
An example
Say: an office with a front door, an archive, a warehouse and a server room. Management has a key that opens everything: the grand master key (GMK). The Office department has a master key (MK1) for the front door and archive. The warehouse has MK2 for the front door and warehouse. Cleaning gets a key for only the front door and archive.
Who has which key and which door it opens, you record in the key plan. That way, if a key is lost, you know exactly which doors are at risk.
The terms
| Term | Meaning |
|---|---|
| Grand master key (GMK) | Opens all cylinders in the key plan. |
| Master key (MK) | Opens a group of cylinders, for example one department. |
| Group key | Opens an agreed group of doors. |
| Access matrix | The table of keys and doors: a tick where a key fits. |
| Key plan number | The number with which you reorder keys and cylinders from the supplier. |
Frequently asked questions about a key plan
Do I need a key plan?
As soon as you have more than one door and not every key needs to fit everywhere: an office, an owners' association or a building with several departments.
What happens if a key is lost?
You check in the key plan which doors the key opened, and decide whether to replace those cylinders. The higher the key type (a master key), the greater the risk.
Can I keep my key plan digitally?
Yes. In Sojolock you manage the matrix, the key register and issuing, and order keys at MC-Cilinder with your key plan number.
