Hello Friends,
i did a RFID door lock, and it was working fine. Now i want to put 2 RFID readers, but i'm unable to. can anyone tell me what's wrong?

code is > 9000 characters, so i'm removed some functions irrelevant to the question. Full code is attached
I did try to change the baud rate of the new one to 14400, but still nothing.
Help please..
Thanks
