power door locks in 06 kia rio

I am attempting to install power door lock actuators into a 2006 Kia Rio5.  the small little hatchback car. 

First, I cannot even get the manual window crank off. I am using a special tool to remove, but I cannot even tell if there is a horseshoe clip.thats how much I room I have to work with before I demolish the door panel. 

Second, from what I can see with the door panel dangling there, the lock/unlock mechanism appears to be a cable as oppose to a traditional metal rod. Can actuators even be installed on these cars that have a cable instead of a metal rod??? any suggestions would be appreciated. 

when you finally get the door panal off, you'll want to look at the lock mechanism itself, OR the tab on the handl that you flip with you fingers (the part behind the handle) to see if there is enough room for a hole for the rod. Those cable set-ups require some REAL thiking.
