A more scientific approach was required I opened up the right hand panel (on advice from others on this forum) and proceeded to pull on everything that looked like it would move ( I think the wiring is now longer than it was before) no go, soo I got a mirror and with a torch saw a spring directly behind the catch stuck a thin screw driver in it and levered while pushing the key/catch and wallah! it opened.
I still don't know why it was stuck after an oil it works fine so fingers crossed (at least I can fix now)
This pic is the access panel
