How do you disable the car alarm on a 206?

To disable the car alarm on a Peugeot 206, you can typically use the key fob to unlock the doors, which should deactivate the alarm. If that doesn't work, inserting the key into the ignition and turning it to the "on" position may also reset the alarm system. If the alarm continues to sound, disconnecting the car battery for a few minutes can reset the system. Always refer to your owner's manual for specific instructions related to your model.
