Best Door Locks For Home Security Australia – When choosing security door hardware, it’s important to know the difference between a single and triple lock and what effect each has on your security door.

Note that a single lock does not comply with Australian Standard AS 5039-2008: Security Doors and Security Window Bars, and the use of a single lock will convert any security door into a barrier door, otherwise known as a security gate. Therefore, in order to maintain the integrity of the security mesh door, it is necessary to use a triple lock.

A triple lock is much more secure compared to a single lock because they lock at three points on the door frame and cannot be opened at the top or bottom.

A well-aimed kick to a wooden door can cause the lock to fall or the door to separate from the frame. Also, a large force applied to the center of a PVC door can cause it to collapse inward or detach from the frame. Breaking down a flimsy door is one of the most common ways to break into a property; Investing in expensive locking systems and advanced security features is meaningless if your door is not strong enough to withstand external force. Here are some steps you can take to improve your doors:

How To Change A Door Lock After Moving Into A New House

Steel front doors have traditionally been used only in commercial and industrial buildings. However, growing security concerns and technological advances mean that you can now also buy steel front doors for home use, which look good and offer much more security.

Choosing steel entry doors over PVC, composite or wood will bring many benefits.

If you are purchasing a steel security door, we recommend that the door meets the following basic specifications:

To make your doors even more secure, if space allows, you can consider installing them to open inwards. Outward-opening doors reduce the risk of kicking or knocking, as you should also apply pressure to the door frames.

A modern, strong and durable door lock will be a wise purchase; especially considering the number of methods thieves have for breaking locks.

However, different locks have different uses depending on the type of door they are installed on. Read our recommendations on which locks are best and which doors.

Steel security doors are usually equipped with a multi-point locking mechanism that locks the door at several points on the frame. Typically, the mechanism locks the door at a minimum of 3 points, but can go up to 4 or 5 (although at Latham we proudly sell very secure entry doors with 19 locking points). Of course, the more points your locking system uses, the more secure your door will be.

Typically, a multi-lock system is controlled by a single euro cylinder, so it is important to ensure that the euro cylinder is equipped with impact, puncture and pick protection. It is also important to have the right size and fit the door so that a thief cannot buy it with pliers or similar tools. You can find more details on Euro cylinder locks in our guide here.

You can find many locks on wooden doors. Below are the most popular ones:

The 5-lever locks are locked from both the inside and the outside. This style of lock is mounted to the material of the door, rather than the surface.

The 5-lever lock should not be confused with the less secure alternative, a 3-lever lock. Locks with less leverage increase the risk of a duplicate key and may not provide enough protection to be covered by your property insurance.

For entrance doors, it is recommended to choose a door that complies with British Safety Standard BS3621.

Night locks are commonly called “Yale locks” and are most commonly used in home scenarios. They are placed on doors that open inwards and are attached to the inner surface of the door. When the door closes, the night latch automatically closes the door.

You can prevent the door from slamming shut by “chiming” the door, usually by pressing a button.

The most secure night lock is an automatic locking lock approved to British Standard 3621. This type of lock locks automatically when closed. Keyless night locks are available, however many insurance companies expect you to install an additional lock, for example, to ensure an adequate standard of security.

Euro cylinder locks are mostly used on PVC or composite doors. Double cylinder locks have a key cylinder on both sides of the door, so you must use one key to lock and unlock the door from both sides. This lock format is usually used for doors that require more security, such as front or back doors.

Again, it’s worth using a lock cylinder that fits the door snugly and doesn’t protrude too far beyond the door profile. If any part of the cylinder is exposed, this is a potential weakness. Also make sure the euro cylinder has impact, pick and snap resistance properties.

To ensure a high level of security, we recommend using hinge screws that are at least 3 inches long. Shorter screws run the risk of falling out of the key over time or falling out when attempting to break it.

It is also a good idea to make the hinge screws used on front doors from a strong, non-corrosive metal, such as stainless steel.

If your door opens outwards, for extra protection, you may want to install hinge screws (also called ‘bolts’), which are designed to prevent the door from being lifted off its hinges.

If you are investing in a steel security door, remember to use strong steel hinges that support the weight of the door. Weak hinges put the door at risk of breaking. We recommend that you purchase the hinges recommended by the supplier so that the responsibility lies with them.

Most wooden doors should have a catch installed. The striker strip is a small metal element screwed into the door frame, especially recommended for wooden doors. The plate protects the door frame from screw friction. When the door is closed, the bolt engages a hole in the strike plate and holds the door closed. Security catches are larger, thicker and more durable versions of traditional metal strikers and provide additional protection against theft, door grabbing, jamming and other door lock attacks.

For optimal security, the plate should be made of high quality steel and use long screws (more than 3 inches). This reduces the risk of the striker plate being displaced when attacking the goal frame.

If your front door has single glazing, we recommend replacing it with double or triple glazing if possible. Laminated glass is an ideal covered glass because it ensures that when the glass breaks, the pieces stick together, making it difficult for an intruder to get through.

A wide-angle door viewfinder will provide a wider focal range than traditional; This means you’ll have a better view of who’s behind the door without having to open it. If you don’t know who they are, you don’t have to let them in.

Digital viewers are also now available. They offer a large screen so you can see your guests clearly through the security camera, meaning you don’t have to squint to see who’s there. This means you get a much clearer and more vivid picture of what’s in your hands.

So if you don’t already have one, consider installing a viewfinder or digital display. If you have one, consider upgrading.
