Its a bit of 1mm aluminium sheet cut to 1.5 wide. I put a little bend on the end just to get it started and then pushed it in and pulled up..

worked first time, almost surprised myself with the ease.
Just thought I would pass this on as I had visions of broken door cards and all kinds of stress trying to get the door open.
Hope it helps someone.
