Hi Steve52
That would depend on why the door won't open. Its not going to be easy in any way because the door is designed in a way that it can't be opened without the system working.
There are some pictures and 'how to' topic on removing the door solenoid pack - this is what latches the door closed and keeps is locked or unlocks to allow it to open.
This is the solenoid pack
This is the topic with more pictures

The solenoid is controlled by the BSI and that can give trouble, and
this topic has some info - right at the end.
The trouble is you can only remove the door solenoid with the door open
If its a BSI electrical problem you may be able to run power down the wires to the solenoid pack, as is mentioned in the topic I linked to. But if its a mechanical door solenoid problem you may be able to disassemble the solenoid from within the car, but neither of these are ideal, are going to be time consuming and not a beginner DIY car fixers thing to do.
You don't say if yours has dead locking, if any of the other doors have problems, if its a remote central locking system and if this works on the other doors.
