DESCRIPTION:
If you have a flat battery on your Nissan (Micra) - and only an electronic key fob.

This video shows you how to use the emergency manual key option. You need into the car to access the bonnet release lever, but without keys you can't get in.

This video was made after this happened to me and I couldn't find the simple solution
I did find dozens of similar options - but not this one.

I hope it's of help to someone!
