Can you ballpark the cost to repair rear door lock? on 1998 Dodge Durango

My rear door lock will not engage. I tried the switch in the truck as well as the remote. I can hear the mechanism in the door do something when I try to lock it but I can still lift the handle and open the door. My key will not go into the lock either. What would it cost at most to have this fixed?

Yea, i agree with reply.

what you will need is a door lock actuator, the part is roughly 80.00 , if you took it to a shop im thinking with parts and labor you wil prabably be in the 230 - 300 dollar range
