Yes, but it hard way. There are couple additional program procedures except key.
Much easier to program new key.
What city are you locate?

I already swapped all components but 2005 XC90 still says "Start Prevented"

In this case need to synchronize your modules and key.
You can remove your CEM, ECM and sent to some service with your key.

if the CEM (Central Electronic Module) is part of the inmobiliser system then i should be able to just swap them and it should all work right?

In theory a key , ECU, and CEM should work as a triplet if moved from car to car.

My guess is they won’t though.
