I need something to work on on this truck. Everything is perfect. I've never had that in a project vehicle.

So now I want to add things. Like power door lock and associative keyless entry would be very nice since I have this on my main mode of transportation. Anyone done this and what complications if any? Seems to be straight forward when considering autoloc setup yet don't want to get into a situation where the truck can't be opened up due to a glitch.
