Hello all, Im new to volvo and to this forum.
question:
i have a 2006 XC90 with blown motor and a 2005 XC90 that i lost the key to, can i swap the ignition switch and ECU from 2006 XC90 to 2005 XC90 and make it work?

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?

Sorry, I cannot understand what do you mean.

i have the original CEM that was part of the ECM and key, should i install that CEM on the 2005 and that will be the missing part i need to get the 2005 to start?

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.

Jimmy might know this definitively
