Another Electrical problem - Daimler Super V8 2001

[fast cars]

I have just had my Daimler repainted, during this process I had the handles, bumpers, door cards and lights removed, putting everything back on I now find the dashboard semi powers up (dash illumination, all warning msgs in green box) and all this without putting the key in the ignition.

Using the key does absolutely nothing, no effect on rotating, the alarm seems to work ok.
I have had an auto elec look at the car but he cannot find anything wrong? Any ideas greatly appreciated

Thanks

Ian thank you very much for the information, battery has been swapped over just in case this was the cause, I have not tried touching the 2 terminals together to dissipate any current so will give this a go, if no joy here I do have another car I can take the BPU from but don't know where its located so please could you let me know?
Cheers

Ian thanks very much again for the advice and info, I think I may have to pack it off to XJ Motors in Chertsey and let them get to the bottom of it as they have all the necessary equipment to diagnose.
