Thanks a million, greatly appreciated, saved me £65.
Car: Focus, Ghia, 07.
It wasn't exactly as described... but nevertheless worked.
In my case after turning the key 4 times, there was no light or signal, so I just pressed a button (the open unlock one), then it made a bip an done, they key was now working.
Then I had to do it again, because out of the excitement I did not activate the second key, so I missed the window :)
