[DelBriella]

Tutorial on replacing the battery in an older Mercedes-Benz G-Class key is as follows: 1. Before replacement, it is best to first understand the battery model of your car key, which is usually written in the vehicle user manual. Then, select a new key battery according to the specified model. 2. From the tail of the key, push up the marked switch, and the hidden mechanical key will pop out slightly. Then, you can remove the mechanical key. 3. Still at the tail of the key, use the just-removed mechanical key to press against the marked position. With a slight force, the key shell can be opened. 4. After opening the key shell, you can see that the battery position is relatively deep. Insert any tool into the gap on both sides and gently pry to remove the old battery. 5. After installing the new battery, ensure that the positive and negative poles are not reversed. Then proceed with the installation steps: first insert the top of the shell, then press firmly on the other end to complete the battery replacement. Finally, don’t forget to reinstall the mechanical key.
