Where is the anti-theft module located?

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your vehicle. The anti-theft module in your Sedona is usually located behind the dashboard, near the steering column. It could be hidden behind some panels, making accessing it a bit tricky. If the module is malfunctioning, it could cause intermittent starting issues like the one you're experiencing. Before diving into the anti-theft module, though, I'd suggest checking the battery and connections, as a weak battery or poor connections can also trigger the anti-theft system. Another thing to consider is that only select models of the 2003 Sedona are equipped with anti-theft systems, so it may be worth the time to ensure your vehicle has one before searching for it. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
