   Hi me and my son picked up a 1999 1.1 saxo on sunday it all seemed to be OK....however today I went to start the car and the key warning light is flashing and it wont start...we must of started it 20 or so times yesterday and it was fine..we were given 3 keys for the car and one of them is not for this vehicle..it will not open any doors etc...but I think I tried to start the car with this key ( it fits the ignition lock but will not turn ) ever since I did this the key light is flashing...do you think that the wrong key may have upset the immobilizer...or is it just a coincidence ? I have read that the key aerial can be a problem...any help would be great thank you .

   Try disconnecting the battery for at least half an hour, generally resets things
