My wife lost the key fob to our 2007 Seat Altea 1.9 tdi unfortunately, the only other key fob we had would only unlock/lock the car. I paid an auto locksmith for a new transponder, program it and cut the key. The car started and drove normally for one day the next it would start then cut out. Asked the auto locksmith to look at it again he did the whole process again but the car still won't start. On the instrument cluster it shows 0-1 which he says is the car recognising the key so he says its not the key programming which at fault but seems to think that the car has some sort of earthing problem which seems puzzling because before my wife lost the key the car drove faultlessly.
Any ideas as to what could be causing the car not to start?
