Help required, rear door won't open Audi A3

[usmangti]

Hi I haven't posted on here for a while but I'm hoping I can get some help.
Today randomly my Driver side rear door has stopped opening. It seems locked however I can't unlock from inside either. This maybe due to the child lock being on but I've followed the process in the handbook of pulling the lever inside and then trying the external handle and still no luck. I think the latch has gone, but my question is how can I get the door open to replace it?!
Thanks in advance.
Ps its a 2010 Audi A3 sport back

Hi wires maybe snapped in the door post rubber if it'd not a faulty lock and you may need to get a positive live power to the oclomg unit to open the door of this is the case here.

I did a car yesterday boot latch broken and locked.
