Nissan Juke drivers this is your answer! Thank you thank you thank you! You saved me time and at least £50. I was very sceptical about using you (sorry!) as I was told that the ONLY way to get my code was for the dealership to take out the system, retrieve the serial number and then get the code. That was BS. Nissan Juke owners - put in a code 3 times to lock the system, the information (serial number, device number, date) comes up on the screen. I photographed it with my phone then found this site. Put the info in to the form and under 20 minutes later I had a 4 digit code. I had to keep the car running for 60 minutes (as it said it was locked for 60 minutes) then put in the code these guys had sent me. Voila the system started up again. I have radio, sat nav, reverse camera all working again. For £18.99. Fantastic!
