Locking plan
A locking plan clarifies the exact functionality of a locking system and assigns the keys to the locking cylinders that lock them.
The keys are embossed depending on the manufacturer of the locking system and customer requirements. In industrial production, the numbering is applied to the key with laser marking or engraving machines ; in the case of locking systems or replacement keys made by locksmiths, it is stamped . Some manufacturers only stamp a sequential number, whereby z. B. the master key (GHS) has the lowest number because it is planned first. Others also use A / B notation; H. the GHS is usually marked with "A1" and the group key as "A2", the individual keys only have numbers or "B1" etc. 7. Individual keys usually only have a consecutive number. This makes it easier for the administrator and authorized expert of the locking system to assign the function of the key. With central lock systems it is common to mark the keys that only close the central locks with a "Z".
The type of lock (e.g. profile cylinder , round cylinder , oval cylinder , padlock , lever lock ) and their properties are also noted. In the case of complex properties with a large number of locking options, it may be necessary to use an IT-supported management system.

The general master key system of a small craft business serves as an example:
| door | closure | Design | length | GHS | HGS1 | GS1 / 1 | HGS2 | GS2 / 1 | GS2 / 2 | Z1 |
|---|---|---|---|---|---|---|---|---|---|---|
| Main gate | 1 | Double room | 40 × 30 | X | X | X | X | X | X | Z |
| Side gate | 1 | Double room | 30 × 30 | X | X | X | X | X | X | Z |

- Legend
| GHS = general master key | Z = central lock |
| HGS = main group key | DZ = double cylinder |
| GS = group key | HZ = half cylinder |
In this example there are three different designs for the locks : double cylinder, half cylinder and a padlock.
The owner has the master key with which he can lock all cylinders in the company. He gives his close office worker the HGS1, which she takes to both the boss's office and the factory floor. Occasionally she also needs a vehicle, so her key also closes Garage 2. He gives his accountant the GS1 / 1, who can open the doors in the office wing, but not the boss's office.
The boss hands his employed foreman HGS2, with which he can open all the doors of the factory hall, the material warehouse and the garages, and can also enter the office building, but not his boss's office. He hands over GS2 / 1 to his journeyman, who usually carries out the orders in the factory hall, who can also open both material stores, but only one of the garages if he needs a vehicle. He hands over the GS2 / 2 to the other journeyman, who assembles the workpieces for the customer, so he definitely needs a vehicle. If the vehicle is from garage 1 z. B. not available because of a repair, he also has access to the vehicle in garage 2. He has no access to material store 2, which only stores the raw materials that are not allowed to go to the customers.
All higher-level keys (i.e. GHS, HGS1, GS1 / 1, HGS2, GS2 / 1, GS2 / 2) are allowed to close the main gate and the secondary gate in the fence. The single key no. 1 also fits both cylinders. There is no key that only closes one of the two gates. Single key no. 8 also closes the main gate and the side gate of the workshop. In these cases one speaks of a keyed alike . Lock 1 is also designed as a central cylinder in which all the keys of all other locks are enclosed (identified by the Z and the corresponding Is in the same column).
