How do you turn off alarm on Peugeot 307 inside car?

To turn off the alarm on a Peugeot 307 from inside the car, you can typically use the key fob to lock and unlock the doors. If that doesn’t work, insert the key into the ignition and turn it to the "ON" position. This should disable the alarm system.
