Mercedes C300 (W205) Key Battery Replacement (Key Fob)

This video shows how you can replace the batteries in your Mercedes C300 Key. This key / key remote uses one 3V CR2025 battery. Please check the type of a battery that your key uses. I replaced them with the same CR2025 type made by Energizer. You can also use other major brands such as Duracell.
Note: There are a few variations of Mercedes keys / SmartKeys and the methods you use to replace the batteries. This video shows the key where the plastic cover opens from the back of the key. Make sure your key uses the same design before using this method.

I wanted to send my friend a video on how to replace the battery and of all the videos I've watched, this is the best one. You explain every step and show what you're doing, and unlike a couple videos I found, you followed the correct procedure to remove the back - a couple had people trying to pry it off with a razor blade! Madness!

Thanks so much dude!!!

CR2032 works

[@bpetertube]

Yes, CR 2032 (3.2mm thick) will work as it is rated at the same voltage, but the thickness is slightly different so it may be "easier" to install the CR 2025 (2.5mm thick).
