In this video you can watch my demo on how to properly change the Mercedes Smart Key battery tutorial. It's actually very easy and you can do it yourself - DIY! There is no need to go to a dealership for that. Good for Mercedes Smart Keys from 2009 till present..<br /><br />If you have any questions, please leave your comments below.<br /><br />Music Credit:<br />You’re free to use this song in any of your videos, but you must include the following in your video description:<br />United We Groove by Audionautix is licensed under a Creative Commons Attribution license (https://creativecommons.org/licenses/by/4.0/)<br />Artist: http://audionautix.com/<br /><br />Music: www.bensound.com<br /><br />Visit: https://MBZMaster.com for more details..
