What is the code to unlock a philips DC 511 car radio

SOURCE: Philips CAR 400 code

This code will not be available for free from anywhere on the Internet as it is not in the available Philips database.

Main Dealer or a Decoding Service who will connect it to a computer to read/recode the code memory chip (EEPROM)

SOURCE: I need the code for my philips car radio. MODEL: CAR400

Please check your Serial Number again to make sure it is correct.
 
If it is correct  , then unfortunately   your  code will not be available for free (or cheap)  from anywhere on the Internet as this Serial Number is not in the available PHILIPS database.
 
It requires access to the original manufacturer`s database which is only available from your Main Dealer .(and a few of the larger Professional Radio Decode Specialists)
 
Otherwise try  a Decoding Service or your local Car Radio / Audio Shop who will electronically "read "/ recode the memory chip (EEPROM) using a laptop and specialist software.

SOURCE: My radio wait up radio code. I don't remeber this

First make sure that the code has not been noted somewhere within the car (underneath the ash tray, glove box , rear of sun visor etc)
 
 
To see if your code is available here  for free then the radio will have to be removed from the dashboard (and if you are lucky, someone may have written the code on the casing ) .
 
If not then POST A BRAND  NEW  QUESTION
 
quoting the radio MAKE+MODEL plus ALL the LETTERS+NUMBERS on ANY LABELS ,BARCODES or STAMPED IN THE METAL CASING
 
Also quote the MAKE of CAR
 
note: Unfortunately not all radios can be decoded using the Serial Number
 
Otherwise try your Main Dealer ...........or take it into a Decode Service who will plug in a laptop to read/recode the memory chip (EEPROM). This takes a few minutes and shouldn`t be too expensive
