Smartkey ?
I only got 1 key on delivery of my CLK500 but my salesperson said there should be two and that the other was on the way. It came in a few days later and then the factory sent another by mistake so I ended up with 3 altogether. There is a regular key built into the plastic housing of the smartkeys that will open doors, glove box etc. but you have to have the smartkey to start the car.
