Yes. That Mercedes key is cooler looking with the chrome though... but yes, the key slides out if you need it (if battery is dead or you want to use it as a valet key) by pushing a button, very small sliver of a key comes out... but it doesn't pop-out like the audi/vw keys that you have to flip out and put in the ignition. even without the comfort access, you don't have to take the key out, but you do have to pop the key pad in the ignition. with comfort access, you only have to put it in the ignition to charge the battery, otherwise stays in your pocket, bag, etc..
