You may use various types of door locks for a number of purposes. Some locks are best suited to doors that lead on the outside of your house, so they offer more protection to prevent intruders from entering.
Other locks are useful for keeping doors safe inside your house, such as bathrooms and wardrobes. They include just enough protection to keep others out, but without the degree of security required for outside doors. Such locks are those that you can lock on the exterior of the gate, rest are only for locking up from the interior of the door, and others are those that you can lock from the outside or within.
The following are some of the types of locks you may find and how they vary.
Doorknob Locks
Doorknob locks are the most common form of lock you’ll see in residences, particularly indoor doors, such as bedrooms and bathrooms. They’re also always one of the ways to secure the front door, along with a deadbolt or safe, lock.
Doorknob locks have a locking mechanism inside the doorknob. These locks have handles on each side of the door and may have a sole or double cylinder, based on whether or not you want the door to be locked from the inside.
Handle sets
Handle set locks have a hold on the outer side or maybe a keyed opening or a twist button on the inner side to lock it. This form of lock features a lock on the door instead of a spring bolt for extra protection. They serve a similar function as a doorknob lock but can offer a more attractive look to the outside of a house.
Deadbolts
Deadbolt locks are a unique mechanism from the door knob, which offers your doors an extra layer of protection. Many homeowners and businesses chose to have both a doorknob mechanism and a deadbolt on their doors to safeguard from intruders.
Deadbolts can lower the risk of unlawful entry by having a safe lock system that makes it almost impossible for a thief to break in the gate. Deadbolts can be both double- and single-cylinder styles, with a double cylinder providing even more protection against unwanted entry to the house.
Chain Lock
Chain locks are the ones you normally see inside the lodging doors. These locks have a door frame grab and a central door lock, just like a barrel rod, but use a chain to close the door rather than a cylinder lock.
The idea of a chain lock is to enable you to open the door a little to welcome someone while holding the door locked. An individual would not be able to come in until you shut the door and unlock the chain, enabling you to open the door completely.
If you are looking for a security chain Australia has many hardware stores so you can easily find one.
Simple Padlocks
Padlocks are one of the simplest types of security systems. Usually, you’ll see those door locks that don’t require high-level protection, such as sheds and door storage units. These locks are not tied to anything else but are locked in themselves instead.
Padlocks may be small or wide and are typically square or rectangular shape with a U-shaped bar. One end of the bar remains in the lock but moves vertically to allow the other end to lock and unlock.
