door popers pop the door open 2 or 3 inches, its like a tunk pop, power unlock unlocks the door, then you lift the handle to get in. door popers are an aftermarket thing so im assuming you want power locks.
since your car did not come with power locks you are going to have to run wires to them. you could get a new door, then you would not have to work on much, all you would have to do is run wires from the door harness to the alarm. thats probably the easiest, this would also be a good time to add power windows if you dont have them already. so get the door, that way all you have to do is run wire.
