passenger front door lock does not work manually or remotely.
door cannot be locked.
after research it's the door latch assembly which is a mechanical and electrical device that locks the door.
a torx 20 and torx 25 screw driver along with a couple flat head screw drivers will help you replace it with a new one ($150) within the hour.

This is common prob in this s 70 Volvo. Daughters car locked from inside and out. Luckily I am Pro Body man. Even for me, this was was extremely difficult job. The lock fails internally. Cannot slim Jim. Must rip door panel off. remove bolts of window Reg. Must cut inch of metal out of way of lock, to get access. Must Air chisel Lock to bits. open door. buy new lock. straighten metal, this is tough part because lock MUST be positioned perfectly , to work properly. I learned the hard way. good luck youll need it. Joe
