My car is a Renault Laguna 2003 After replacing the car battery I have been unable to use the radio . I have tried using Code 2070. The sound comes on for a couple of minutes including bleeps then goes off again. Could I be using the wrong code? Could the code be wrong ?
Any suggestions would be helpful!
Many thanks

jim for me to check the right code.
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 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

Also when entering you must hold at the end to store the code.
IF YOU DONT HAVE ¬ KEY THEN PUSH THUMBWHEEL IN AND SOME HAVE {A¬} KEY

Turn on the radio and the display will show 'CODE'
Use the steering controls for code entry.
Press the [ ¬] button then rotate the thumb wheel for the correct first digit
Press the [ ¬] button then rotate the thumb wheel for the correct second digit
Press the [ ¬] button then rotate the thumb wheel for the correct third digit
Press the [ ¬] button then rotate the thumb wheel for the correct fourth digit
If the correct code is now shown on screen,
press and hold the [ ¬] button for up to 10 seconds to store the code

FOR NO STEERING CONTROL
press the first preset button for the 1st digit,
second button for the 2nd digit
third button for 3rd digit
forth button for 4th digit
then press and hold button 6 to store. for 10 seconds
