   take the battery off for a 10 mins
   if not
   the immob is a black box.
   it can vary in places ive seen,
   under the steering column
   or behind glovebox.

   Are we taking about an after market immobiliser? if so it is more or less easy to disconnect, as the previous post suggested you need pretty much first to find the immo box.

   disconnect power of battery and then 10 mins put back on
   and try that.
   
   if not
   removing the immob
   just pull it out
   its on a clip but just push/pull then pull the box
   easy
   
   your suppose to remove the immob box when the car is running though, not sure what it will do if you remove it when not running.

    thanks bud will do it tomoz.
    
    does the battery for the key fob make a difference in the case of it not unimmobilising the engine, its only cos iv noticed the connection is shite and the range is ridiculously small?

    yea sounds like the immobilisers playing up just make sure the car is running when you take it off mate or it can lock the ecu and thats not a cheap fix,

    Hi,
    
    Right the central locking system is actually a different system in your car the problem is just the immobiliser which uses the transponder chip in the key, thus as other member have advised try to get it started and disconnect the immo box, if the car won't start then the ECU needs to be unlock, if this is the case I can sort that out for you but you would need to send the ECU to me,
    
    Regards
    Daniel.
