Hurrah! I managed to fix it. Tried again while the car was unlocked and door open to see if i could hear any clicks and it miraculously started to work???? The strange thing is that the drivers window went down even though I clicked lock??
Last night when I got home I bent over to take my shoes off and noticed the cars lights had come on because I had accidental pressed the unlock button. I looked out and locked the car. When I got up this morning both windows were open even though I don't think that I accidentally pressed the open button long enough for this to happen and I had not noticed it when I locked the car.
Also very strange is that all the radio settings are now recognised as well where as they weren't when the remote lock was not working.
