How to Disassemble and Assemble a Mercedes Key?

Method for disassembling and assembling a Mercedes key: On the side of the wider end of the key, there is a gray sliding button. Slide it once, and the mechanical key will pop out. There is a hole at the back, and in the middle of the hole, there is a button that can be pressed down. Use the mechanical key to press it, and the key will separate. Mercedes offers models such as the S, SL, CL, E, CLS, CLK, CLC, SLK, C, G, GL, GLK, and ML. For example, the Mercedes S is a top-tier luxury car launched by Mercedes. In terms of body dimensions, it measures 5209mm in length, 1872mm in width, and 1473mm in height.

To disassemble a Mercedes key, start by locating the small seams along the edges of the key. Once found, gently pry it open using a thin plastic sheet or a small screwdriver—avoid applying too much force to prevent damaging the plastic casing. Carefully remove the battery cover after opening; the battery inside is usually a CR2032. Take out the old battery and replace it with a new one, ensuring the correct polarity. When reassembling, align the clips and press firmly to secure it. Avoid performing this process in humid environments to prevent water damage and rust. I also recommend wearing gloves to protect the key's surface from scratches. Regularly replacing the battery is crucial—every two years is ideal—to prevent remote failure. DIY saves money and is convenient, but avoid using metal tools to prevent short circuits.

I previously disassembled my Mercedes key myself. Start by carefully prying open the thin gap on the side of the key using a credit card or plastic opening tool, gently letting the cover pop open. The battery is usually located in one corner inside the key. Replace it with a new CR2032 battery, ensuring the correct orientation. When reassembling, you should hear a click to confirm it's securely in place. Beginners are advised to check online tutorials first. BMW keys follow a similar method—avoid forcing them open as the clips can easily break. Replacing the battery can resolve button malfunction issues, but remember the key contains a chip, so keep it dry and away from magnets. After the operation, test if the car door remote works properly. Keep some tools at home for routine maintenance to extend the key's lifespan and avoid expensive repairs at dealerships.

Disassembling a Mercedes key is not difficult. Look for a gap on the back of the key and use a thin tool to pry it open, being careful not to damage the plastic. Replace the battery with a CR2032 model, align it properly, and press to seal. Regular maintenance helps prevent malfunctions.
