VMA405 Not allowed!

Modules General
1

Hello.
I have a RFID read and write module VMA405.
I connected it to an Arduino, I loaded the example sketch from Arduino.
I can read the Serial number of the card, but the Key seems to be wrong !

On the Monitor, I have :
101 106 251 170 94
Not allowed!
101 106 251 170 94
Not allowed!
101 106 251 170 94
Not allowed!

From the User Manual, I followed this :
10. Bring the MIFARE card or tag in front of the VMA405. The card code will appear on the serial monitor,
together with a “Not Allowed” message.
11. Copy this code, check line 31 in the sketch and replace this card code by the one you copied.
*
This integer should be the code of your MIFARE card/tag.
*/
int
cards [][5] = {{117,222,140,171,140}};
12. Recompile the sketch and load it into your controller. Now, your card will be recognize

But this doesn’t change anything.
Is there another Key ?
Thanks

Change this line
int cards [][5] = {{117,222,140,171,140}};

into this
int cards [][5] = {{101,106,251,170,94}};

Thanks for the answer.

Yes ! Now it is working with the rfid tag.

But not yet with the rfid card…

That does have another ID.
So you’ll have to check for both ID or write the same ID into the card.

Yes, of course.

Hello, trying to add the other RFID, but how does it look when you add the 2nd one?

int cards[][5] = {{117,39,150,21,209}};

That’s were I am getting confused

Thanks for the assistance
