Changing the Batteries on your Mercedes Smart Key

This video is different than the plethora of other videos explaining how to change your Mercedes Smart Key batteries ... because it makes the distinction in the differences between the type of key. Older keys come apart very different than newer keys .... good to know.

I scratched the hell out of my fob just like you trying to follow other videos. This is the only video that mentioned the correct method for getting access to the batteries. Thank you for saving my sanity.

Thanks for taking the time to help people who encountered the same issues as you. You helped me brother. Kudos.

My god can we send this man like 50 bucks for this video!!! I wasted so much time watching key fob videos that NEVER said there were different fobs and different ways to replace batteries. You sir just saved me from ripping my fob open out of pure rage. Thank you for this knowledge

Your video just saved me after two hours of being frustrated beyond belief. Every video before this said my key was the pop off one, and I couldn’t not figure it out. Damn near broke my key. Thank you so much for taking the time to show the difference. I appreciate it so much.

The only video that is useful for 2007 cl600 model. We kept trying to open instead of slide watching wrong videos and were going crazy. Many thanks!

Paul - Thank you! Thank you! Thank you! I have a 2008 Mercedes E350 and yours is the only video I could find on YouTube (as of this writing anyway) that showed the correct way to open its key fob. Unfortunately, by the time I found your video, I had completely ruined one of the two fobs by trying to open it the incorrect way (removing the back). That left my husband and I with only one fob for the car.

Now six months later, the remaining fob was requiring more pushes to unlock the car and I knew I had to replace the batteries. I remembered your video and pulled it up immediately. Changing the batteries was a breeze. Thanks again!!

Thank you so much!!!! Today is a holiday and can't get anyone on phone!. You saved me worrying on a trip tomorrow. I have a 2016 glc and it worked great.

Why would someone dislike this? This is one of the most informative videos regarding battery changing.

[paulleivers]

Thank you for this. Most of the other youtube videos do not mention the 2008 key sliding mechanism. Excellent.

OMG, yours is the third video I watched, seems third time's the charm. Odd that the old way is so much easier than the new way, maybe Mercedes made it so people would pay dealers to change it. Thank you for the simple instructions.

This vid points out there is a difference between older MBZ and newer MBZ key fobs. From 2010 and newer, the fob back cover pops off; and 2007 to 2009, the fob end slides out. For each of them, there is a latch that prevents the key fob from coming apart during normal use (two different types of latch). For the newer fob, the latch is up and down, and prevents the back cover to pop up. For the older fob, the latch is towards the side (opposite side where the key ring hole), and prevents the fob end to slide out. You remove the mechanical key, shine a flash light into the slit, and you can see the latch. Use a small flat head screw driver to push on the latch.
For the newer fob, you push the latch and work to pop up the back cover. For the older fob, you push the latch and work to slide out the end. (For the older key fob, there is a thin small ring that pops up, and you can attach your key ring to it, to give you the leverage to pull the fob end out, which pushing on the latch).

Thanks, Paul, you're video saved me from destroying my fob…

[notvlicense]

THANK you Sir!! Watching other videos I actually broke the black cover try to get it off... On my spare key I slide it like you showed... So easy when you know how. Thank you.

[peterboxhoorn]

Thank you for sharing. I was just a frustrated like you sir. Your video showing the right way for my S class model. Thank you!

[irletter]

Thank you! Your's is the only video that explains that the battery casing slides out rather than popping the back

[skorpsaiyan]

That was so helpful. I have a 2005, 2007 and 2014 Mercedes and all 3 keys are different! Almost broke my 2007 one thinking it came apart like 2014. Thank you!!!

[Hassanaboulhosn]

Mr. Oaks, your suggestion is well appreciated ! Good job, Paul ! 😊

[Hulk]

Your video was more informative than all the others!

[richardherndon]

Thank you! That really helped. No one else bothered to explain that it's different on 2008s.

[Mcoogie]

Wow this actually saved me. I just watched 20 videos and was going crazy. I'm glad I didn't give up and found this video. Thank you 🙏 ( If you still don't know how to pop the latch in this type, read my reply to this comment for instructions.)
