Doors not locking

[Sparky1275]

Wondered if you can help. Just picked the van up from being serviced
On my way home I noticed the drivers door was saying it was open. Now at home all doors are shut and it still won’t lock.

Possible door lock switch issue.

Switch is integrated in lock mechanism.

Any ideas how much a lock is for the drivers door?
