need advise on type of doorlock actuator to buy?

i know its an older car and lacking a lot of features which most cars today come with standard,   but i am aware how the UK, Japan and other countries had more accessory options available for the CRX, like power locks or windows, mirrors, heated seats, etc..., plus they had the CRX SiR, etc . .,     and alot of us in the U.S. are frustrated how we just got the basic CRX with no options available or any of that cool extra stuff,   but the only explanation is they were just trying to compete with the other cars selling in the U.S. which were basic models too, so they thought they would sell more that way. so you were saying that if i wanted to be able and turn the key in the drivers door to unlock both the drivers and passenger doors at once, i would just need one motor?,    when you say motor, are you refereing to an "actuator"?        i really did'nt want to have to turn my key into the lock cylinder of the doors anymore, and just wanted to have simple keyless entry where i unarm the alarm remote and it unlocks the door,   and then also locks when i arm it.     

i have locked my keys in my car a few times recently, like after it fell in between the seats and i thought it was in my pocket and just shut the door locked,     or leaving it in the ignition and thought it was in my pocket already and closing it,   and i never pay a locksmith and instead rely on my friend to help get in my car,   and lately the easiest way i've found is getting in through the sunroof, but this last time the guy almost broke it, so it was frustrating especially since i just have been doing a lot of work to my sunroof recently and got it all working good again, but now have to mess it all up trying to get in the car through it to get the keys ! if i have keyless entry,   then it seems like it would be easier cause i would have to press the arm button in order to lock the car, as opposed to having the latch on the inside of the door in the locked position and closing the door, but then realising the keys are inside the car, so it should solve that problem for me having the power locks.

Yes, the UK version only had a motor (= actuator) in the passenger door, therefore just try and see if working the driver's lock slide or key also operates the passenger door lock, otherwise wire as I showed above. One has to be careful, major Civic build = Japan, US and UK plus French and Chinese versions. Up to 2000, Japanese Civic was 1" narrower and 3 door or Coupe only, all CRX were Japanese build but as you said quite rightly many local options.

Japanese and US cars had a "primitive" lock system where you could lock the door with the car open and "slam lock it. All Euro cars have a mechanical interlock, i.e. if the catch at the lock isn't thrown, i.e. thinks door is open they won't lock
