sorry I am little slow compare some of you guys, how exactly do they work?

 

Well what do you want to know they both do two different things. The key is a "FoB" so the car is keyless and the bluetooth alows you to make and receive phone calls through your speakers in your G.

 

Intelli-key sits in your pocket (and stays there)....just push the door button, and ignition button etc.

Bluetooth allows hands free calling, and as CLG35 says, the signal passes thru the car's system speakers.
Both terrific features.

Both previous posts touched on it briefly, but I'll be a little more specific.

The intellikey, is basically a distance-sensing fob. You can honestly have the key in your pocket the whole day and never take it out. Once the car senses you're close to the car, you can just press the button thats located on the door handle and it will unlock and you may open the door. The same is with the trunk. Once you're in the car, the car once again senses your inside, and all you have to do, is turn the key whole to its ignition position and start the car. Its not exactly a push-start like the M, you have to twist it instead, but the key does not have to be inserted.

The bluetooth, theres a green send button and a red end button (just like cellphones) mounted on the steering wheel. You must own a bluetooth capable phone and im sure the owners manual and the cell phone manual have directions on how to set it all up. When you set it all up, when you receive a call, you can simply press the send button to answer the call, and the voice of the incoming party will be played through the speakers of the car. Then you may press the end button to end the call.
