I Need code becker radio.

Hi,

I changed the battery in my car and now I can't get the radio to work .
It'd be great if someone could help me find the four number code for it.

It's a Becker Mexico BE-0837, Serial: A6616952

MCU: 80C31
EEPROM: BAW574252
PA: TA7250BP X2

It's requesting four number code, can someone please help me?

Best wishes,
:) :)
