Depends which doors...
Commonly, the front door lock units suffer broken wires in the door-to-body loom. Remove the door lock switch and make sure power is being applied to all three terminals on operation and that the relay is clicking. Remove the door panel, locate the two wires to the lock solenoid and confirm voltage present on switch operation.
