does hyundai accent 1997 need actuator?

I want to install remote starter/keyless entry on Hyundai Accent 1997 but not sure if I have to buy door lock actuator (door motor)?
Also are there any good instructions for newbies how to install remote starter/keyless entry system on Hyundai Accent 1997.
I've found the wiring diagram on this site, but not sure how to proceed further.
thank you

P.S I already bought this system -> https://www.kprokorea.com/p1-kr700.htm

Does the car have power locks?   short of moving the lock lever on the drives door or turning the key, is there any other way to lock and unlock the drivers door?

You're looking for an electric NOT mechanical pull switch on the driver's door that locks ALL the doors inc. driver's.
Or go to the passenger side. If there's a keyhole in the door, see if that locks/unlocks ALL the doors. If so you don't need an actuator. My guess from working on coupes of that vintage is you will need an actuator in the driver's door. Tell us which then we can go from there. Being oriental origin, they all conform roughly the same, if you don't need an actuator, the trigger wires will be in the driver's door entry cable, probably pick them up in the driver kick panel.

I can open the doors with keys only;
there are no keyholes on the back doors,
only on front ones,
and when I open one door, either driver's or right one, all doors do NOT open - Only that individual door.
It's so annoying, that's why I want to install keyless system that with one click will open all doors.

So, do I need the actuator?
Do i need only one or for each door I want to open with keyless entry system?
thank you!

If the front passenger door will only open that door using the key you need an actuator. If the driver's door only does that door you need 4 actuators!
