Hope helps (remember to rate this answer).
We have one answer from radio decode experts and they tell us:
CM5903 does not use the normal memory chip for its security
code.
inside your radio .
photo of the relevant tags and can possibly use a soldering iron
then please email and we will advise you further.
Keep in touch.
It still requires a code.
But the code for Model CM5903 is hardwired inside the radio instead of using an electronic memory chip (EEPROM). What we require is a CLEAR photo of the green circuitboard inside your radio.
From this we can find the relevant tags and work out the code for you to enter. We will send a photo showing the details required on the circuitboard...
Keep in touch.
Hey man i got one of these, can you help me to unlock the code? The radio is open yet.

Lift the front plastic trim around the radio if fitted ,then two holes either side ,make some tools out of a piece of fence wire in a U shape to push into these holes .Then wiggle them a bit then radio will come out .Post the becker chassis number for the radio and i will generate the code no problem .
97119 is code generated from 5903 number as becker uses a 4 number to generate the code
blaupunt uses a 10 figure number
grungig has 8 numbers
sorry cannot help anymore than that,
alpine 3 ?? a clue i will look through generators again and see what i have
back in 5 mins hopefully
6531 is code with a clarion decoder ,still trying with other code generators so dont go away
sorry i just dont have the right code generator ,have one for mercedes alpine but it doesnt work ,tried all the others to no avail ,the universal ones ,try the dealer they should be able to get it for you or just fit a new radio one with sd carfd and usb support so you dont need CDs .i have tried but ?? iam beaten sorry

Sorry we are not allowed to get out radio codes. It is for theft reasons. You will need to go to the dealer to get the radio code. They will be able to give you the code just by the VIN #
Remove trim pieces along the dash that are in line with the radio using a trim removal tool or large flat screwdriver. then remove the philips(Cross) screws holding the radio in place & pull it out towards you.
RADIO CODES
These
codes are anti theft security codes and each one is unique to the car
VIN number and the radio chassis serial number. The code was give to
the original owner along with entry instructions to reset the radio
whenever the battery has been disconnected. What you must do now is
contract the dealer for instructions on how to retrieve the code to
unlock the radio. There may be a charge for this and you may also
need to remove the radio from the dash, it varies by module and year.

I cant get the radio to do anything other than say "CODE" and if I hold a couple of the buttons, "Mode" and another one it sais "BMW Alpine 3" but I cannot figure out how to enter a code?
Okay super but how do I enter this code, I cannot get the radio to say anything but "code"?
How do I enter the code once i have it?
The radio just says "code" and will not react to any button pushes either in combination or singly?
Help?
Yes but, how do you get the radio to accept the code?
My radio just says 'code" and I can't get it to do anything?
