Cant open rear door.

[DBXdarkangel]

Hey guys. I've removed my rear door handles to paint them and replaced them ok but the nsr door cable has unhooked from the door it handle and I have a rear door child lock on. Is there anyway I can open the door so I can unscrew the outter door handle from the Inside?
I mean how can I open the door from the Inside with a child lock on?
Can't remove door card as the screws are underneath the door to remove it.

Oh and now the front passenger door won't open from the Inside of outside. I can see the cable so it's connected to the handle and there no child lock on the front door.
It worked fine to let my passenger is bit now can't open the door from Inside or outside.
Seems weird as it's all started since I've took the exterior door handles off to paint and now I got issues since I've refitted them
