my MG ZR 03 drivers door won't unlock!

Hi, I've just brought a bargin MG that has an issue wit the central locking. The passenger door will unlock on the fob(but you've got to be quick before the door locks again). Once its opened I press the unlock button 3 times and it makes a crazy clunky sound, click unlock again and it remains unlocked...



The drivers door, hmmmmm....

It looks like someone has already attempted to have a go, and not succeeded. The pull clip has also been removed. I have been unable to look at the mechanism. The door card is fully attached. The door refuses to open even with the key in the lock and after I've gotten the passenger door open. It seems to make a clunking sound when the open button is pressed but no joy.



I've read about if you can get to the deadlock and then cut this off I may be able to open the door.



Normally I'd just get suck in but I've a possible prolapsed disk so unable to do anything. If I take this to a garage what sort of cost am I looking at as I can't use it safely untll that's fixed.



Many thanks for any suggestions

Si
