Thanks again. This my second time referencing this great video.

Easiest video to follow! Complete instructions! NO annoying voices or music! This guy did an amazing job! Thank you for your help! You made a frustrating to figure out job so easy! (Worked for my 2013 ML350)

Wow!! Mine worked the minute I tried. Popped right off. I watched a couple videos before yours but this one is by far the one that helped. Thank you!

This video is very simple, to the point and made it so easy for me to open the key fob for my 2008 E-350. Only bought 1 battery so had to have my husband go to auto zone real quick to get the second battery. Thanks a bunch.

Well done!! Thank you for the “pushing up on the tab” explanation. Most people wouldn’t explain this.....cheers!!!

Watched other videos with other methods... frustrating because they didn't work. This one was perfect! Worked like a charm. Thank you!

Thank you for helping me save time at a dealership . . . Well done !!!! Information is so powerful.

Simple yet accurate video. Work just as explained. Thanks.

Thanks for taking the time to show this process. Big help!

I watched other videos, but yours best explained how to get the cover off. Thanks very much!

the best video on this issue, you point out the angle to insert valet key , which is the key point to pop up the back cover

Thank you. Finally I did it. This video was much easier than the other ones. 👍👍

Thank you for your help

Thank you for info video.

Good video for instructions to change the CR2025 battery. Thank you. I have a 2001 E320 Wagon with a few year old, yet the newer chrome and plastic key fob.However, I was hoping for a little more information. I changed the battery, actually finding the same one in my photographic camera remote control. I first took the battery out of the Mercedes Key Fob. It is apparently fine as it still runs my camera remote. I took the newer one from the camera remote and put it into the key fob, and it still does not work- it flashes the turn signals and the key fobs signal is apparently being received by the car computer- yet the mechanical door lock tabs won't move up or down. I think in the video you might want to add that once the new battery is installed you should check to see the little red light come on when you press the buttons, as you did not mention that. So is there a chance when the battery gets week that it will not bring on the little red light, which other videos mention is just at the top and lower left of the panic button on the surface, or also if you point the narrow front end of the key at you, the infrared light is showing their on the tip when you to press the buttons. I'm not seeing this light. Again, is it possible that the batteries I'm trying are too weeks or nearly worn out? Because here's another symptom I'm noticing. When a press the lock and unlock buttons, it causes the turn signal lights on all 4 points of the car to flash as they usually do in the locking and unlocking mechanism. However, the door lock tabs do not raise or lower. So I'm assuming this is a mechanical function in the door locks themselves or a fuse is burned out that controls these door locks mechanisms. There are three different locations in the car for fuses- under the hood drivers left side, to the left of the driver side dashboard, and also in the battery compartment under the rear right seat. I've checked the first two, but I haven't checked the battery compartment, perhaps there's another fuse there for the locking mechanism. A fuse that may control the remote key entry there, also. There are also other indications from other videos about an antenna in the car, not receiving the signal from the key. And then there is also a video that tells how to synchronize the key to the cars computer so all these other considerations must be checked. I just thought I'd recommend all these other possibilities for other readers to consider.

Well played sir 👍🏿

Thank you my friend

Thank you! You have saved me a trip o he dealer and it was easy just like you said

Nice job ... worked like a charm. I don't get the thumbs down on the video .. it was perfect. I guess you're not a jar of Nutella ... you can't make everyone happy.

Thank you!

Very nice information
