Well, shops will usually charge between $75 - $100 per door just to install the power door lock itself to allow you to do keyless entry, then ontop you would have to pay for a keyless entry (remote operated) system or alarm system that does keyless entry as well. Installing power door locks on its own is a lot of work about an hour per door in addition to installing a keyless entry unit or alarm.
So the answer is yes, i don't know of any shops that would install door locks and provide you with the door lock actuator for free
