My 2001 vw golf gti (vr6) won't shut off when I turn my key to the off position.

What is your question?

The car will sometimes try to start all on it's own too. For example, I had my car locked just after driving it and I head my car alarm going off so I unlocked the car and opened the door and seen that the radio was on and the gauge cluster was lit up. The ignition was in the off position and the keys were out of it but it acted like it was in accessory mode. Please help me! This car is becoming a disaster!!!
