Trouble with RFID-RC522

I have been trying to read Mifare Classic RFID keys using the RFID-RC522 module to no avail.

After a bit of googleing I installed the MFRC522 library using the Arduino IDE. The Arduino Uno I’m programming on is already soldered to the RFID reader with all the default connections with the exception that the reset pin is connected to pin 8 instead of pin 9. This is configurable so I just changed the #define and assumed that would work. I used the DumpRFID example and made my changes and it just hung forever waiting for a card to be read. No luck. I commented out the return statements so I could see a little more info and got a bit.

When I force the print of the dump I get this:

MIFARE_Read() failed: Timeout in communication.

I scanned my key with my phone and was able to get the data off it.

Here is my code.

#include <deprecated.h>
#include <MFRC522.h>
#include <MFRC522Extended.h>
#include <require_cpp11.h>

 * Example sketch/program showing how to read data from a PICC to serial.

 * This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid
 * 
 * Example sketch/program showing how to read data from a PICC (that is: a RFID Tag or Card) using a MFRC522 based RFID
 * Reader on the Arduino SPI interface.
 * 
 * When the Arduino and the MFRC522 module are connected (see the pin layout below), load this sketch into Arduino IDE
 * then verify/compile and upload it. To see the output: use Tools, Serial Monitor of the IDE (hit Ctrl+Shft+M). When
 * you present a PICC (that is: a RFID Tag or Card) at reading distance of the MFRC522 Reader/PCD, the serial output
 * will show the ID/UID, type and any data blocks it can read. Note: you may see "Timeout in communication" messages
 * when removing the PICC from reading distance too early.
 * 
 * If your reader supports it, this sketch/program will read all the PICCs presented (that is: multiple tag reading).
 * So if you stack two or more PICCs on top of each other and present them to the reader, it will first output all
 * details of the first and then the next PICC. Note that this may take some time as all data blocks are dumped, so
 * keep the PICCs at reading distance until complete.

Any Ideas on what could be wrong?

And post a link to the board you're actually using (best would be a link to it's schematics). MFRC522 is only the chip used on the board. The rest of the component on that board may have a big influence on the result.
