Best Key Fob Of All Time?S

Well, since BMW revealed what the i8's key fob will look like, it got me thinking, what in your opinion is the best key fob?

I like the i8's but it's a bit techy for me. I used to like Mercedes Benz's but that seems quite outdated now.

My favourite key fobs as of 2013 is:

Jaguar
Bentley

What are yours?
