The key is something that is part of life and cannot be separated from our daily lives. Yes, that's why if we lose our keys, we will have a need to contact an emergency locksmith. But sometimes, calling a locksmith is time-consuming. So, it's better to have emergency spare keys rather than rely on locksmith all the time. We usually have various types of keys, such as car keys, motorcycle keys, house keys, cupboard keys, and even some people hold safe locks to keep important documents and objects from being stolen and lost.
