Mercedes Benz S550 W216 Add New Key programming with Autel IM608 XP400 EASY! 

Yes but I do it this way because it's easier access for programming esl which I do everyday, thanks for watching 👍🏾

Good question.. in the advanced menu on the scanner, "all keys lost" option is a name they use on how the scanner will prompt you. It's a shortcut because if you choose "add key" it will attempt to verify original and new key are they same etc.. all keys lost option skips all of this and just generates the key, it does not delete existing keys in the eis.

thanks a lot for replay that mean the old key will stay working even we do ALL KEY LOST?@@globalcommerce7654

​Does It only applies to MB or for every other vehicles too, about choosing AKL? 🤔 ​@@globalcommerce7654

Yes, I explained in a different comment, check it
