Replacing a **Mercedes-Benz key fob battery** generally costs around **$5 to $15** if you do it yourself. Most Mercedes key fobs use standard batteries like the CR2025 or CR2032, which are easy to find in stores or online. If you go to a dealership for the replacement, they may charge for both the battery and labor, bringing the total closer to **$20 to $50** depending on the location and model. However, Mercedes key fob batteries are easy to replace on your own by following the instructions in the owner’s manual or on the Mercedes-Benz website, so you can save by handling it yourself.
Anywhere from $175-$250 from the dealer, don't buy the key from ebay.
