The Nissan anti-theft system combines a few different layers to keep your car safe. There's an immobilizer that stops the engine from starting without the right key, plus a security alarm that goes off if someone tries to break in. Some models also have additional tech like motion sensors or a panic button. It's pretty straightforward and effective, and you can hear the alarm from a good distance, which is nice for peace of mind.
