Locks are an essential component of home security. Locks keep our valuables safe. We find them on our doors, safes, and we find them protecting lockers full of our possessions. Locks are the barrier between thieves and our things, and we use them every single day. But have you ever stopped to wonder how exactly they work? Below we describe how a typical lock works.
Nowadays, locks have become technologically advanced. Locks may involve all sorts of cutting-edge tech including fingerprint scanners, retinal scanners, facial recognition software, fobs and a myriad of other devices. However, for the vast majority of us, we still deal with locks that require a key to open. Most front doors, for example, still require a key. These locks are call pin-and-tumbler locks. Here’s how they work:
Pin-and-tumbler locks have a series of spring-loaded pins. These locks contain cylinders. These pins havevarious heights and correspond with the key teeth. When the key is inserted in the lock, it pushes the pins up to their respective heights. This makes them match up flush with a track. When the pins are all properly aligned, the cylinders can turn and the lock is opened. All of the pins need to be pushed into place exactly in order for the cylinders to turn. which is why each key is unique to its respective lock, and why only that key will work for that lock.
Locks are a great way of keeping your things safe, but home security in our day and age requires more than just locked doors.
