How to delete the maintenance key on a Citroen C3

To remove the key (maintenance symbol) that appears on the Citroën C3 dashboard, follow this simple procedure:

1. With the car turned off, press and hold the black button located on the right side of the dashboard (usually the trip odometer reset button).
2. With this button pressed, turn the key in the ignition (do not start the engine, just turn the ignition on to turn on the dashboard).
3. Continue holding the button until the key symbol starts flashing and a 10-second countdown appears on the dashboard display.
4. At the end of the countdown, the maintenance key light will disappear from the dashboard.
5. Release the button, turn off the ignition, and turn the car back on to confirm that the key has disappeared and that the system has been reset to notify you of the next service interval (usually every 10,000 km).

This procedure is valid for various years and versions of the Citroën C3. The key will reappear at each scheduled maintenance cycle.

If you want, repeat the process every time you have your car serviced to turn off the light on the dashboard.
