HELP--- keypad security gone haywire after I typed in wrong numer

Discussion in 'General Motoring' started by Hugh Gundersen, May 2, 2004.

  1. Hi Folks

    Not me but a friend has (I think) a 406 Diesel Estate some 6 -8 years old. Not a bad car
    but he is forgetful. Anyway on Friday driving from London to Manchester his gear lever
    came out the socket so he called the AA who fixed it but when he went to start it again he
    was so flustered about breaking down on the M6 he typed the right numbers in the wrong
    order on the keypad security.

    AA towed him to Manchester and the local dealer told him to leave the ign on and
    eventually it will re-set.

    Can't see it myself but:

    Is this correct?

    Is there another way to overcome this problem?

    Any help or advice would be welcome as he has to get back to London by Tuesday.

    Thanks

    Hugh

    I have a late 96 405 with keypad immobiliser. I would think that it would be
    much the same as an early 406.
    The information I have is....

    Keypads have to cater for incorrect operation. If an incorrect code is
    entered on 3 consecutive occasions the keypad is neutralised for 30 minutes.
    If the code is not confirmed , switch off the ignition and restart the
    operation. If the red and green lights are both lit, switch off ignition
    then wait for approx. 1 minute . Switch on again and retry.

    If the keypad has "failed" in some way. Options

    - code can be "sometimes" be reset to factory default by an
    autoelectrian. Try Autotrader for names or if you have LSUK locally
    then give them a bell and see if they can help (at a price of course) AA
    homestart is a good option to have in this case.

    - get the autoelectrian to check the wiring/bypass the immboliser keypad if
    duff unit.
    - get another immobilser keypad from a scrapped 406

    - speak to Peugeot. I really have no knowledge of what parts required but
    guess new ecu at vast expense. Probably cheaper buying a new
    car.

    This information is from personal experience - I have no professional
    experience of this security system or auto electric's. Wish I did.
    I would make a fortune with all the OTT gadgets in cars.

    How is that carried out?

    Would it not be the same as disconnecting the battery?

    The coded number is held in the ecu as far as I know, that is why it is not
    affected by battery disconnection. Bit like info stored in ROM in a
    computer.

    Hi Bob,
    Yeah, right ! Even if Mindwipe doesn't often post here, his answers &
    statements often (if not always) brings the cure.

    Hi GT and Hi all,
    I have just been down the rocky road of key pads, Codes, Pumps and Belts
    with my 1996 405 TD LX
    Here is what I have learned,,,,,

    The diesel pump has a control unit with a normal diesel shut off valve
    connected to it via the black plug on the side of the pump, this is also
    connected to the ignition feed and the key pad,
    The key pad tells the control unit the code, the control unit then gives the
    shut off valve a live feed,
    all of the pump electrical and electronic systems are protected with heavy
    tamper proof metal plates,
    the only way to get to the control module and shut off valve is by REMOVING
    THE PUMP and centre punching the tamperproof bolts in an anti-clockwise
    direction,this will then allow the plates to be removed,
    a normal, or ignition controlled shut off valve can then be fitted, or cut
    the wires to the original shut off valve and apply a feed from the ignition
    and earth,

    HTH
