More About Locks
Locks have been around for a long time. The first locks were made of wood. They were not as safe as the ones we have now. Now, we have locks made of metal and strong parts.
Locks help us every day. We use them at home, school, and on bikes. They keep our things safe and sound. Without locks, it would be hard to keep things safe.
In the future, locks may get even better. Some may use special codes or even your face! This will help keep our things even safer.
