How to Replace the Battery in a Citroen Remote Key?

On the remote key, locate the gap at the end of the car key. Use a screwdriver or a blade to insert into the gap and gently pry the car key open by moving it up and down. Then, remove the button battery from the motherboard, install the new battery, and finally, reassemble the outer shell.
Replacing the battery in a Citroen remote key is actually quite simple. I was a bit worried the first time I did it myself, afraid of damaging the key shell. First, find a quiet place and prepare a new battery, usually a CR2032 model, which can be bought at supermarkets or auto parts stores at an affordable price. Take out the key and carefully check the back for a small gap. Some models have a button on the top that pops out the metal key head, and then you can gently pry open the plastic shell—don’t use too much force. Once opened, you’ll see a small round battery. Carefully remove the old battery with a fingernail or a small tool, being careful not to touch the internal chip. When inserting the new battery, make sure the positive side faces up and place it in the original position. Then, close the shell until you hear a click, indicating it’s properly installed. Finally, test the lock and unlock buttons to ensure they work correctly. Key batteries typically last one to two years, so avoid dropping the key or exposing it to high temperatures to prevent damage. Once you learn this method, doing it yourself saves money and is convenient—no need to visit a car repair shop.
