    bypass transponder / immobiliser???

    I am concidering buying a attempted theft write off, the ignition wire has been cut etc and car will not start, i think transponder is missing????

    Is it possible to just bypass transponder / immobilizer???

    If not, what am I looking at to put this right?? can I just get new transponder and keys from breakers or does it involve new ECU or programming or what??

    Any help greatly appreciated.

    When they do get pinched its more than likely the result of a burglary and the car keys taken , if you get keys from a scrap yard you will need the coresponding ecu ,or get a new key and have that coded to the car about £100, and a little re-soldering the cars ignition wires

    Yeah nick the keys The transponder send a signal that is Keyed in to the ECU's software, It is called a software lock, If the wright code is not transmitted to the ECU, it is nothing more than a fancy paper weight If the transponder module is not on the steering rack your wasting time and money If it is then a quick trip to the stealers with the V5 and order the passport card pay them for that and then the key and then programing it up, You can't programme this up yourself it's a stealer own for obvious reasons

    The transponder is built into the key, does it have the orgional keys? It may just be that that wires to the transponder pick up have been cut aswell and it doesn;t start for that reason

    The transponder pick up and the ECU are coded together and you would need the keycode card to get anything programmed into it

    Yes the pick up's missing. All i've heard is that they are coded to the ECU and need replacing as a pair

    Lets see if anyone else says otherwise or it will be a trip to vauxhall to pick their brains
