E90 replacement emergency key?

[excel monkey]

I've lost the emergency key that slides out of the main key.

Obviously I can get a replacement from a dealer, but are there any cheaper alternatives?

I'm not fussed about the key actually working. Just want a cheap blank to fill the space where the old one was. Car is a 57-reg E90.

I would want to have a rough idea where I lost that key as it may come back to haunt you.

Agreed - if you cant find it, and dont want to buy a replacement you could block the locks incase someone has the key and tries to get in the car
