Start Button Roadster

I purchased this for my Smart Roadster, as my dog has to sit in the front ( Only a two seater car ) and the huge Smart key sticks up in between the seats. My dog would now and then knock the key and switch off the ignition, whilest driving... I decided to buy this so the dog cannot switch the ignition off, as the button is flush and cannot be hit or knocked.Yes some say this is a security risk, as if you leave the car unlocked anyone can jump in and start it!! (More fool you if you leave it unlocked ) but it can be set up, so you have to do a certain combination of presses to activate!!Only draw back I had, was that it came without any instructions. I had to log into the suppliers website for them, and then translate from German into English. Besides that it's a wonderful gimick and flashy addition to a very limited and quirky car.
