Method for replacing the key battery of the new Mercedes-Benz SLR: First, push the marked switch upward, remove the mechanical key, open the key casing, then pry out the old battery and replace it with a new one. The Mercedes-Benz SLR is a supercar under the Mercedes-Benz brand, with body dimensions of 4656mm in length, 1908mm in width, and 1261mm in height. In terms of power, the Mercedes-Benz SLR is equipped with a 5.5L V8 turbocharged engine. Regarding its appearance, the SLR features a sleek, streamlined engine hood, simple front fender air vents, eye-catching side-mounted exhaust pipes, a compact rear, and gull-wing doors, all of which add vitality to the SLR.
I enjoy tinkering with car gadgets in my spare time, especially smart keys like those for Mercedes-Benz. Changing the battery is a piece of cake. The key design for the new SLR is excellent—it usually has a small notch or button. You can gently pry open the casing with your fingernail or a flathead screwdriver. Inside, you'll find a CR2032 coin cell battery. Remember to check the positive and negative terminals before removing the old battery to avoid reversing them. When inserting the new battery, make sure it's clean and properly seated, then press the cover back firmly until you hear a click—that means success. Afterward, quickly test the remote unlocking and ignition functions to see if they're working again. If there's still no response after replacement, it might be due to poor battery quality or internal contact issues in the key. In that case, I recommend checking the original manufacturer's manual. The whole process takes just five minutes. Doing it yourself not only saves money but also gives you hands-on experience, avoiding unnecessary expenses at the dealership for major repairs. Successfully handling such small tasks always makes me proud—after all, understanding the finer details of your car helps extend the lifespan of its components.
