To replace the battery in a Mercedes-Benz G55 AMG key, follow these steps: 1. Push the marked switch upwards from the tail of the key to remove the mechanical key; 2. Use the mechanical key to press against the marked position and gently open the key casing; 3. Use a card to pry the old battery from the gaps on both sides and remove it; 4. Install the new battery, reassemble the casing, and reinsert the mechanical key. The Mercedes-Benz G55 AMG has the following dimensions: length 4738mm, width 1855mm, height 1952mm, wheelbase 2850mm, fuel tank capacity 96 liters, trunk capacity 481 liters, and curb weight 2590kg.
I've been driving a Mercedes for many years, especially the G55 AMG, and have encountered a dead key fob battery several times. The first time I changed the battery myself, I was a bit nervous, but later found it super easy. There's usually a small groove or screw hole on the side of the key – just twist it gently with a coin or small flat-head screwdriver to open the back cover. Inside is a coin cell battery, typically CR2032, which you can buy at any supermarket or auto repair shop. Be gentle when removing the old battery to avoid damaging the circuit. When installing the new battery, pay attention to polarity – the flat side faces down, and the raised side faces up. Finally, snap the back cover shut by pressing the clips. The whole process takes less than 10 minutes, saving you time and money compared to going to the dealership. I recommend keeping spare batteries handy, as I've seen some guys ruin their key fobs due to leaking from old batteries. Always test the remote after replacement to ensure everything works properly, so you can drive with peace of mind.
