Have you ever wondered how door locks work? It's interesting (if you get the chance) to learn how a lock works. There are several different kind of locks out there, but I think I will just go over the most common types of door locks, the ones that we all can relate to like the mechanical locks, keyless systems, electronic locks, and tubular locks - the most common type of lock today.
Inside Door Locks and How They Work
Most keyed locks have a pin and tumbler locking mechanism. Which means there are spring loaded pins and these are loaded into a series of little cylinders. Each of the little cylinders' bottom is called a pin and top is called a driver. When inserting the key, the springs will be compressed, the key lifts the pin and it pushes the driver into the upper chambers of the cylinder. When you put in the correct key for the cylinders the bottom and top pins will be aligned and the key can turn. The bottom pin will be in the key chamber and the top part of the pin rests on top of the bottom half with gentle pressure of the spring when the key is not in the lock. When an incorrect key is inserted, the key will not align correctly with one or maybe more of the spring loaded cylinders - not allowing the key to turn by placing at least one of the pins or drivers in the way. While it may seem complicated, the process is actually pretty simple!
Common Types of Door Locks
Most locks are mechanical. Mechanical locks operate by one or more pieces of metal (tumblers, levers, or latches) falling into a slot in the bolt, which prevents it from being moved. Not all, but most mechanical locks require keys to unlock and lock. Let's explore some different types of door locks in more detail, shedding light on their inner workings and the unique features that set them apart.
- Tubular Locks
Tubular locks are a good example of a mechanical lock and, like I said earlier, the most common type of lock found in peoples' homes. These locks can be installed easily on a basic door or a standard prepped door. Tubular locks have a keyed cylinder on the outside and turn button or a push button on the inside to manually lock it. - Mortise Locks
Mortise locks are often found in older homes and offer superior strength and durability compared to standard cylindrical locks. They feature a heavy-duty lock body that is installed within the door, along with a mortise cylinder that houses the locking mechanism. Mortise locks typically incorporate a combination of pins, levers, and springs to provide added security against forced entry. - Padlocks
Padlocks are portable locks that can be used to secure a wide range of items, from gates and sheds to lockers and storage units. They consist of a shackle that can be opened and closed with a key or combination, along with a locking mechanism housed within the body of the lock. Padlocks come in various sizes and designs, offering different levels of security depending on their construction and materials. - Keyless and Electronic Locks
Keyless locks, also known as electronic or smart locks, have become increasingly popular in recent years due to their convenience and advanced features. Electronic locks operate by an electric current. And are sometimes capable of operating independently with an electronic control assembly that is mounted directly to the lock and allows access by a code or a key. Smart locks use technology such as biometrics, keypads, or wireless connectivity to grant access without the need for a traditional key. Keyless locks offer added security features such as remote access control, audit trails, and temporary access codes, making them an ideal choice for modern homes and businesses.
Lock Picking and Home Security
While locks are designed to provide security, they are not entirely immune to manipulation or picking attempts. Lock picking involves using specialized tools and techniques to manipulate the internal components of a lock without the correct key. However, high-quality locks with advanced security features, such as security pins, hardened steel construction, and anti-pick mechanisms, can significantly deter picking attempts and enhance overall security.
