Yeah, it's b.s. Put on wheel dollies and push it out. The dealer should do it if a tow company won't. This is actually a serious problem. If the thing dies in traffic, there is no way to push it out of the roadway. They can not be put in a neutral gear. We work on them all the time and the batteries die and they have to be jumped. The owners manual has specific instructions to do it but a typical jump box will do the trick. The fire marshall wants us to have the keys readily available to them in case of a fire so they may be able to move a vehicle if they need to. Most of the time you can just pop it in neutral and push, no so with the electrics. I am not even supposed to run the bake cycle after painting one for fear of burning up the batteries. The paint pretty much has to be baked though so we do it anyway. No problems as of yet. As far as the key goes, they are expensive to replace on most new vehicles, BMW being in excess of $400 and you need to sign over your first born child just to get one.
