This is a community forum, there are many members who would be willing to help. But you have to give enough information about the problem or project. Such as what are these keyboards you mentioned, and what are your relays controlling?
Also what important role will the Arduino commands line tools play in your project? That is the forum section you chose to post in.
Please read the forum guide in the sticky post at the top of most forum sections to find out what you need to include in your post so that other forum members will be able to help.

We seem to be having communication problems. I can't understand you and you either can't understand me or you are ignoring my advice.
Perhaps you could try explaining your idea/problem in your first language, then use Google Translate to make an English version.
You could also use Google Translate to help you understand my suggestions, and then follow them.
ok. tnx for advice
Am I close?
Control 32 relays with a PS/2, numberpad. First 16 relays controlled with NUMLOCK OFF, second 16 relays with NUMLOCK ON.
yes
no matter which button turn on . It is important that only 1 of the 16 is always on. and from secund allso only 1 ( NUMLOCK ON OFF)
What are the 32 keycodes for ps/2 numberpad?
I dont no 
Can we PM?
Probably not. Pretend you "PM" and post it here.
Keycodes will be handled by a library (search "arduino ps2 keyboard")
Have you made the ps2/arduino interface (hardware)?
I waiting new numkeypad and then i can read.
Search for the information online before it arrives... and read a PS2 library to use with the Arduino.
okay
Search "arduino ps2 keyboard library"
i can't finde with NUMLOCK ON - OFF
I have only this one GitHub - techpaul/PS2KeyAdvanced: Arduino PS2 Keyboard FULL keyboard protocol support and full keys to integer coding
Project like this one https://ncjweb.com/bonus-content/W0IH-MultiRadioBandSwitch.pdf
