I've never done manual shaved doors, but I do know some people that use window modules to roll there window down so they can open there door from the inside. I have never had problems with my civic's doors opening, I did have problems with my old mazda. This was because I didnt use the proper method. My civic is set up much better and this is how I will do my current mazda. My battery has had not enough volts to start the car, but my door still opened. You battery would have to be down to 8volts or less for the solenoid to not work. I've had 9 volts pop my latch.
It should not be too hard to figure out how to route the rod from the key tumbler to the door handle. The lock unit pushes and pulls the rod up and down, and the exterior door handle does the same thing. If you are worried about cutting up the rod, go to the wrecking yard and pic up a spare for a testing purpose. Or take a picture of your door without the panel and everyone on here can take a look and give you some pointers. My truck is not at my house right now so I can't take a picture of the door rods.
