    Hi all,
    I have an S40 with only one key to start the engine. I took it to few
    local locksmiths' equipped with immo key reader/writer to get clonned
    but they say my key's transponder is a crypto 44 type philips , so they
    can determine the type but no luck to copy from my original key with
    cloning device.

    Later I've been told that it is possible for their head office to make a
    key for me but said that it is required to leave my car at local
    locksmiths' for about a week until immo unit arrives to head office and
    back. I don't want to leave my car, both because of personal and
    security issues. So are there any one knows how to access immobilizer
    eeprom? I am an electronics engineer so I can read immo eeprom with
    eeprom programmer if once I can find it :) Also I have a vadis
    documentation showing immo components but I am not sure in which order
    to dismantle the parts. Any help is greatly appreciated.
    Thanks.

    Below is the immo and locking system components captured from VADIS.

    All you need to do is go to your local Volvo dealer & have them cut a
    key for you & have them program to car

  3. All you need to do is go to your local Volvo dealer & have them cut a key
    Or you can hide the workingkey next to the antennaring on the ignition and
    then have som keys cut without the immobilizer chip in.
    If you are afraid of keeping a working key in the car, you can always cut
    off the metal part of it.

    Thanks for your reply, of course I have this option. But I don't want to
    pay so much (about five to ten folds).

    This is another alternative but it doesn't seem logical to me. This way
    immobilizer security will be completely bypassed, I don't want to do
    this in order to have a spare key. Both leaving the key in car close to
    transponder antenna with metal part keeped on it or not means
    sacrificing either immo security or original key itself. Thanks for your
    suggestion anyway,
    Cheers!

    A design engineer working at locksmith's head office supplied me exact
    photo of immobilizer equipped in my car. So that I can correctly able to
    locate the according part number, also cross-verified with VADIS. Part
    number is 30864648 for 2000 S40 with turbo. And this is the link for
    picture:

    I didn't accessed that part for now but I've been told that immobilizer
    dump is inside a 93c56 or 93c66 smd eeprom chip. I'll share further
    advancements later on.

  7. Or you can hide the workingkey next to the antennaring on the ignition
    If you have had the spare key programmed it also needs to be programmed into
    the the memory og the unit in the car. Perhaps thats why it doesnt work.
    When you reprogram that box you delete all keys and put them all in at one
    time.
    I dont know if other companies than Volvo can do that.

    Called Volvo and they want 400$ for a new key fob with chip and I have to have my car towed to the dealership, I just bought the car a 2003 Volvo s40 for 200$ now seems I've got to spend over 500$ just to get the car there and have it re-programed. OK so I know that the immobilizer cuts ground to the relays point in fact I went to the starter solenoid and found that when I re-grounded the relay I could crank the car over, I think I would have to find the injector, fuel, starter, and I'm sure other relays and re-ground them anyone else think this would bypass the immobilizer
