Keep your car key at night far away from the outer walls
Here is the reason. If the key is close enough to a wall, outside of which a thieve can sense it, the thieve can use a range extender to transfer the signal from the key to you car, open the door and drive away. Nice and clean.

Yep started doing that a while ago when the whole proxy/remote key readers started coming out. Make sure you test the key and check that it doesn't get read from the box. Don't assume the box would automatically work.

If you have a mBrace subscription you do have vehicle location and remote locking.

The best thing to do, is to design the keyfob to open and close. So you can remove the small battery when you leave the car somewhere. Just insert the battery when you’re close to the car.
The metal box may work but the battery removal will turn the signal off and you don’t have to worry about the signal extender.

It will flash a warning on the cluster informing you that the key is no longer detecting in the car (in case you dropped off the person when that was carrying the fob and drove away unknowingly without it). The W221 will not take any action other than beep with the warning on the dash. It will not turn the engine off.
