How do you change the ignition key on a Peugeot 106?

To change the ignition key on a Peugeot 106, you'll first need to ensure you have the new key programmed to the vehicle's immobilizer system. Insert the old key into the ignition and turn it to the "On" position without starting the engine. Within a few seconds, turn the old key back to "Off" and remove it, then insert the new key and turn it to "On." This should allow the new key to be recognized by the vehicle's system. If you encounter issues, consult a professional locksmith or a Peugeot dealer for assistance.
