You can buy a remote control box on eBay for about $10 that will allow the doors to be opened with a key fob. The box attaches and interfaces directly to 2 wire actuators- the relays are built in. The door lock actuators are less than $10 for a pair. Granted, this doesn't give you the power unlock/lock from within but you can just as easily flick the lock lever as you can press a lock button. or just use the key fab in the car . A simple solution for power locks for less than $25 bucks.
