Sorry if this has been asked already but could not find anything before I got bored

After standing for a couple of weeks the engine will not turn over. All lights etc.

I assume this is an immobiliser problem so: -

How do I reset it.

Cheers

 

Are you certain the battery has a charge? What year 940? "All the lights" ....what? are on? off?
