Lost Radio Code

With lockdown ending I tried to start up the vehicle to no avail, A new battery was required for my 2003 Peugeot Boxer Autosleeper Nuevo and I now need to put in a code for the radio. How do I reset this?

Have you looked through all your documents, there may be a note of the code in there. To be honest, I didn't think you needed a code unless the original radio has been replaced.

If you disconnect the battery the radio loses its security code. If you have it, check the original paperwork for the van, esp. the radio stuff as the code info. should be there. Otherwise you could try contacting your local Peugeot dealer or perhaps somewhere that specialises in in-car entertainment may be able to sort it for you.

If it’s a Peugeot radio there are lots of free codes on google just need serial number.

failing all else most auto sparks will decode it for about £20 - I wouldnt place much faith on a Peugeot dealer having it or giving/selling to you if they have it.  Requests by me to various dealers for radio codes for various car marques have been met with "we dont keep that information" "we cannot supply that information" and "that will cost ....an obsecene amount of money".
A local guy will re code the radio to a number of your choosing

The secret code input instruction in your Peugeot user manual should be supported by a separate piece of paper detailing model no of radio with the 4 digit code. As you've requested advice, my apologies for your plight if I've stated the obvious Regards.

I remember replacing the engine battery in my 2006 Nuevo and it didn't need a code. Then I found out that Nuevos of that age had the radio wired to the leisure battery and i also replaced the leisure battery and still didn't need a code. Hence my comment earlier about not needing a code. Maybe it only loses the code memory after a certain period of time.

I agree there Paul. I've replaced both my V and L batteries over the years and never had to put the radio code in. I've been told the only time you need the code is if the radio is installed in another vehicle.

I've found that the radio can lose its code if the battery is just allowed to run down too far. It seems to use a little bit of power from the battery to keep the code active. I presume this is a theft deterrent; a stolen radio is useless without its activation code.  This isn't just on our Transit, our VW Passat was the same; disconnect the battery for any reason and you had to re-enter the radio's security code.

Must be different on other vehicles. I have the code for my radio but never had to enter it even after both batteries have been disconnected for days.

I had this problem on our old C max, had all the Ford documentation, but the code given for the radio didn't work. I had to remove the radio to fix a faulty volume control and lo and behold the code was on a label on the radio chassis. Then realised the key code and radio code had been transposed on the documents! This was after I rang a local auto electrician who gave me a code number over the phone.

 whenever I have to disconnect a vehicle battery for any reason, I connect, using croc clips, a small (moped) sized battery to the vehicle terminals to keep the codes.

you can buy a lead (<£10) which one side connects to a battery (such as your leisure battery) and the other plugs into the OBDII socket of your vehicle.  This allows you to not only disconnect the battery without losing radio code but also maintains the ECU settings.

Losing the ECU settings on a motorhome probably isnt a big deal but can cause some cars to run like tractors for a while until the ECU relearns
