    Hi all,

    I'm hoping someone can help me out here because with it being Sunday no one
    at Peugeot will answer the phone.

    I have recently bought a 1996 406. The guy I bought it from forgot to give
    me the immobiliser code. This wasn't a problem as the key is coded somehow
    and as long as I start the engine quickly enough it works fine. The guy has
    been out of the country but has now sent me the code. I thought I'd try it
    out... I guess after the first failed attempt I shouldn't have bothered
    trying it another 2 times... I'm not sure if he's given me the wrong code or
    what but now it is beeping constantly and I can't start the engine?

    Any ideas please?

    I left it for a while and it seems to have reset itself. It seems the code I
    have is wrong or doesn't work. Would it be expensive to have it found
    out/reset? I have no card or details of the immobiliser.

    Cheers. At least I can start it now...

    Ok Ben am I right in assuming you are talking of the immobiliser with the
    number pad beneath the dash?
    If so, I seem to recall it had an option to program it so that the code was
    on the key
    (effectivly defeating the whole point imo, but that's by the bye).
    If you're starting it ok on the key, you are in the same situation as later
    owners who don't have the pad to play with anyway.

    If you're worried about only the key knowing the code, I believe certain key
    cutters can read them,
    so get a spare made(?)

  4. Maybe it was the radio code that he sent you? Tell him what happened and
    ask him again.

    If you're starting it ok on the key, you are in the same situation as
    Thanks for the advice Jim, I'm not bothered about the key knowing the code.
    The problem comes when the key stops working and I can't start it. Also, if
    you don't start the engine within a minute or so the immobiliser comes back
    on - meaning I have to lock it, wait, and unlock.

    I'm guessing that if I had a spare made I would have to somehow get it coded
    to the immobiliser...

    I believe coded keys can be reproduced, that's what I was trying to say.
    I like the other suggestion though if you do need to use the keypad.
    The previous owner will be your simplest bet and may have thought you meant
    the radio code.
    There is also something like a maintenance code (see the handbook)
    which is set when taking it in for service if you don't want em to know your
    He may have set it to that.
    I never had it on the key on my old 406 so have no idea of time available to
    start from key etc.

  7. Hi Ben

    You are obviously not receiving private emails. I can provide you with the
    four digit workshop code for the 1997 406, which may or may not work on your
    Email me if you are interested.

    My reply to address is a valid one, but I have sent you an email. If the
    code works I'll be very happy. Seems shocking though that such a thing even

    Thank you.

    All you need to do here is, with the ignition on, press the large plip
    button for a few seconds, while watching the engine management light
    on the dash. It should flash a couple of times. Then you can start the
    I wouldn't have thought key cutters could read the plip, which is
    where the code is stored. The only way I know is to get a plip from
    Peugeot (which can take five weeks as they come from France) and then
    get your dealer to cut a key blank. They do not need coding to the
    immobiliser when you get them as they already are. The dealer will
    need to know the number from your key which is on a paper tag inside
    the plip, to order it.
