Need Radio Code

Hi All,
I bought an used car last year, now I need to change battery as it is going to die soon. The technician from the garage told me that I would need radio code when I install the new battery otherwise the radio won't work. Unfortunately last summer my car was broken into by thieves and the technical manual was taken away. Now I don't know the code. How can I find the code please, if anyone can help?
Thanks in advance!

you need to remove the radio.
they are too small holes each side of the radio
use an old metal coat hanger 4 darts or very small screwdriver or long nails.
put into holes about 4-5cms and push outwards sideways
and carefully pull radio forward.
you must do the holes on each side at the same time

Then post the numbers/letters from below the main fat barcode
something like 7700xxxxxxtt123 or 8200xxxxtt123 or
the security code like Q123 or T0U123
can be found in a small box then i can help you
off of the radio
