The tutorial for replacing the battery in an old Mercedes-Benz G-Class key is as follows: 1. Before replacement, it's best to first understand the battery model of your car key, which is usually written in the vehicle's 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 take out 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 removing the key shell, you can see that the battery position is relatively deep. Use any object to slide into the gap on both sides and gently pry to remove the old battery. 5. After installing the new battery, make sure 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 put the mechanical key back in place.
I've changed the key battery for my old G before, and it's quite simple. First, prepare a CR2032 button battery, which can be bought at supermarkets or hardware stores. Locate the metal button on the side of the key, press it, and pull out the mechanical key. Then, gently insert a small flat-head screwdriver into the gap of the key shell to pry it open, being careful not to apply too much force and damage the casing. Once opened, you'll see the round battery; use a plastic pry tool to remove it, and remember to place the new battery with the positive side facing up. After closing the back cover and reinserting the mechanical key, test whether the buttons light up. It's best to try opening the door and starting the car to ensure it works. The whole process takes about ten minutes, and doing it yourself saves you around a hundred bucks in labor costs. If the key shell is old, it's a good opportunity to clean out the dust inside as well.
I'm very familiar with replacing the battery in an old Mercedes G key. The key is to buy the correct CR2032 battery, as other models simply won't fit. First, locate the small button on the back of the key, press it with your fingernail to release the mechanical key. This will reveal a gap in the key casing. Use a coin or thin card to gently pry it open along the gap—avoid using metal tools to prevent scratches. Once the back cover is open, simply remove the old battery, paying attention to the correct orientation when installing the new one. Before closing the cover, check the position of the clips and align them properly before pressing firmly. When reassembling, make sure to insert the mechanical key all the way until you hear a click. Patience is crucial when doing it yourself; rushing can easily break the clips. Regularly replacing the battery is important—it's a hassle if the remote stops working.
