[LaMarcus]

The method to replace the battery in an older Mercedes-Benz CLA45 key: 1. From the tail of the key, push the switch upwards, and the hidden mechanical key will pop out slightly, allowing you to remove the mechanical key; 2. Use the just-removed mechanical key to press against the slot position, and with a slight force, the key shell can be opened; 3. After opening the key shell, you can see the battery position is relatively deep. Insert an object along the gap on both sides and gently pry to remove the old battery; 4. Begin installing the new battery by inserting the top of the shell first, then pressing firmly on the other end to complete the battery replacement. The older Mercedes-Benz CLA45 features a front grille with a dual-slats design combining thick and thin elements, a redesigned front spoiler, and red brake calipers paired with new-style alloy wheels, creating a striking visual impact. The interior adopts an all-black color scheme with extensive use of chrome trim, delivering an excellent visual effect. The vehicle is powered by a high-performance version of a 2.0L turbocharged engine, with a maximum power output of 360 kW and a peak torque of 450 Nm.
