OK, heres my tuppence halfpenny.
I have a remote start on the Hundy, professionally fitted.
In order to remote start the car, a manual gearbox for reference.
you must follow this procedure.
Stop car moving, engage handbrake, gearstick to neutral.
Remove key.
Exit vehicle with turbo timer and engine running.
Lock vehicle using fob within one minute.
Then and only then will the car remote start from the fob.
I was lucky, Mello Yello is 17 years old and in true Jap fashion has all the cutesey things like a neutral sensor available at the ECU.
I won't disclose the make of the alarm but it is a CAT 1 thatcham approved job.
Whilst I accept it is illegal to start the car on a road, it is not illegal to start the car on private property.
As for the immobiliser part, if your car like the omega has a built in immobiliser what they do is take a working key, hide it very carefully within the vehicle somewhere inaccessible, then wind an antenna around said key which the alarm then 'amplifies' at the ignition barrel.
Just my observations/thoughts.

PS I love getting in my toasty warm car with de-iced windows whilst the neighbours are freezing there behinds off
