Wear gloves and safety glasses to protect yourself. Make sure your car is in a safe, well-ventilated spot. This helps reduce risks while you work on the alarm.

Before you start, read your vehicle’s manual. Knowing your Nissan’s specific instructions and parts helps you disable the alarm right. Learn where important wires and switches are to avoid damage.
