How to Replace the Remote Battery for the New Mercedes-Benz?
2 Answers
Method for replacing the remote battery of the new Mercedes-Benz: 1. From the tail of the key, push the marked switch upwards, and the hidden mechanical key will pop out slightly, then you can take out the mechanical key; 2. Use the just taken-out mechanical key to press against the marked position, and with a slight force, the key shell can be opened; 3. After opening the key shell, you can see that the battery is positioned deep inside. Insert an object along the gap on both sides, and with a gentle pry, the old battery can be removed; 4. After installing the new battery, reassemble following the disassembly steps. Mercedes-Benz is a German luxury car brand, considered one of the world's most successful premium car brands, with main brands including SMART and Maybach.
I used to replace the batteries for new car keys myself, such as Mercedes-Benz remotes. The newer Mercedes-Benz keys usually have a small button or snap design on the back. Use a fingernail or a small flat-head screwdriver (avoid metal ones to prevent scratches) to gently pry open the cover. Inside, there's a small round battery, mostly CR2025 or CR2032 depending on your key model. When removing the old battery, note its orientation: the positive side usually faces up with the engraved side. Install the new battery the same way, ensuring it's not reversed. After installation, press the cover firmly until all snaps click into place. To test, hold down the unlock button—the key's indicator light should turn on, or simply try opening the car door to check functionality. Extra tip: Batteries cost just a few dollars at supermarkets; avoid off-brand ones as they may affect lifespan. If the key has advanced smart features, you might occasionally need to re-pair it after replacing the battery, but it's usually a quick one-step process, saving you the hassle and cost of visiting a dealership.
