LoJack is like a special radar that helps find stolen things. Let's say you have a special toy car that you really love and someone takes it. You can call the police and they will install a special device called LoJack in your car. This device will keep sending special signals that only the police can read, and these signals will help them track your car down even if it is really far away.
Just like how you can use your remote control to find where you left your toy, LoJack helps the police find where your toy car is. They will use their special computer to read the signal and then they will know where to go to rescue your toy car! Cool, right? So, LoJack helps keep your special things safe and sound, just like your parents keep you safe and sound.
