Does anybody know if an aftermarket kit exists that works with the 2004 Honda Accord DX?

I was looking at the central locking kit for cable actuated door locks from http://www.a1electric.com/ but after seeing how short cable on the passenger door is I question if that kit can be installed successfully.

Here is a guide how the cable kit is supposed to be installed: http://www.a1electric.com/cablelock.htm

Here are some picture of my passenger door that show how short the cable is. I don't see how a sucessful installation would work on this door. For one the cable is quite short and not in a straight line and then there is probably not much clearance between it and the door panel. (click on image to view larger size)



I'd appreciate hints, tips, and stories of failures. Of course success stories are what I'm hoping for.
