If you’re ever stranded in a car and need to lock it so no one can steal it, there are a few things you can do. First, find somewhere safe to park your car. If you’re in a city, try to find a well-lit area with plenty of people around. Second, make sure the doors are locked. If the doors are unlocked, someone could just walk away with your car if they have the keys. Third, use a keychain or remote locking system. These systems require you to enter a code before the car will start. This is helpful if you don’t have access to the keys or if you’re worried someone might be watching your car while you’re away. ..
