Alex, I believe that you get both the SmartKey and the Keyless transponder when you get the Keyless Go option. You can start/stop the engine with either the transponder or the key in your pocket. I've started an E320 with only the key and I've started an S500 with the card only. Go ahead and see if you can start your CL with only the key. It's a nice feature if you don't wanna bother with the lock/unlock buttons on your key.
The only problem with Keyless Go is that it doesn’t work all the time, or maybe just here where I live. When I tried unlocking an S500 once with the card, it wouldn’t unlock the first try. I had to try all the doors and at last it did. When I got inside, I couldn’t start the engine with the card, so I used the key. The same happens to an E500 owner that occasionally parks on my street.
I think the reason it doesn’t work around here is that because the Empire State Building is blocks away from where I live. As you know, the antenna on top of the building transmits radio signals, which what the Keyless Go feature uses to lock/unlock and start/stop your car. I believe that it interferes with the system and that’s what causes it to stop working, at least where I live. I don’t know if Jack has had any problems with it so far, especially if he’s near high-rise buildings in LV with antennas on top of them.
Just in case you ever come to Manhattan, don’t use your Keyless Go
