There are many control units fitted to this car they all control different functions around the car.
The instrument cluster is a small computer itself.possible dry joint if all working ok now.
The door locks are controlled by a door lock module called the ZKE unit this also controls windows and alarm functions etc.
I suspect both problems are not linked to each other.If both door locks are not working the only thing you can check is that fuse 6 & 29 are ok.
