Hello,
now i´m write the sketch to another arduino with rfid and relay.
It doesn´t work .
From fhem i can trigger the relay and in serial monitor the card´s where shown with serial.
In fhem the lockstatus is set to off, when the card is in near of the reader, the lockstatus on doesn´t send to fhem.
But the relay doesn´t trigger by card.
Where is the mistake?
The problem is the lockstate doesnt set to on.

* The MySensors Arduino library handles the wireless radio link and protocol
* between your home built sensors/actuators and HA controller of choice.
* The sensors forms a self healing radio network with optional repeaters. Each
* repeater and gateway builds a routing tables in EEPROM which keeps track of the
* network topology allowing messages to be routed to nodes.

* REVISION HISTORY
* Version 1.0 - Henrik Ekblad
*
* DESCRIPTION
* RFID Lock sensor/actuator
*
* Use RFID tag to lock/unlock a door or trigger a scene on your controller.
* This example sketch allows you to add an optional relay or solenoid
* which can be activated/opened by RFID or controller.
*
* Use the I2C wiring option for your RFID module and connect to the following Arduino pins.
*
* RFID Arduino
* ----- -------
* GND -> GND
* VCC -> +5V
* SCL -> A5
* SDA -> A4
*
* Use normal wiring for NRF24L01 radio
*
* Attach a optional relay or solonoid lock to pin 4

Hm, with other arduino now it works.
