your best bet would be to look inside of the owners manual if you are the first owner and you did not set it up, if you are not the first owner you will need to contact the original owner and see if they still remember the code- if those options don't work you will need to contact Sony, good luckUnlock code for old Sony CDXMP700R using remote RMX95.
