firstly many thanks to you all for your helpful reply's we have today found the cause of this problem it turned out to be a problem with the ignition key its self i paid to have new cases fitted as the buttons on my old ones were broken it would seem that when the guy changed the circuit boards over he failed to notice that there is a small block on the side of the internal case. luckily i kept all the old cases and the fitter today noticed that it had not been put in the new case 2 minutes later and he had put this in the the new case and hey presto car started first time although changing these cases is a simple thing i did not do it my self i prefer not to touch what i dont understand thanks again for all your helpful reply's
