How to Replace the Battery in a Citroën Key?

[Leslie]

Citroën key battery replacement: First, locate the seam on the end face of the remote key, insert a screwdriver or blade into the seam, and gently pry the key open by moving it up and down. Then, remove the button battery from the motherboard and install the new battery. Finally, reassemble the key casing. Below are several signs that indicate low battery in the key: 1. Key malfunction: If you suddenly find that you need to press the key several times for it to respond, this indicates low battery, as the signal is not being transmitted. 2. Dim indicator light: The remote key usually has a small indicator light that illuminates when operated. If the light becomes dim, it also indicates low battery. 3. Reduced remote distance: If the key only works when you are closer to the car than usual, this is another sign of low battery. However, unresponsiveness could also be due to excessive nearby signals causing the car to fail to react. Some thieves exploit this vulnerability, so it's important to develop the habit of closing the door after exiting the car and giving it a manual pull to ensure it's locked.
