Why Should My Security Door Have a Three-Point Lock … And What is it?

why should my security door have a three-point lock … and what is it?

When choosing hardware for your security door, a three-point locking system is the best choice for enhanced protection. But what exactly is a three-point lock, why is it better than a single lock and why should I consider adding this feature to my security door?

Your home is only as secure as its weakest point of access and, unfortunately simply closing the door isn’t going to stop a potential break-in. It’s crucial to ensure your door has a quality locking system in place to deter potential thieves and be certain that your home is secure. Three-point lock will enhance the protection offered by your security door and ensure your home and its contents are protected from burglaries.

An upgrade to your front door security certainly isn’t just about boosting your aesthetic curb appeal. Once you have carefully considered all the different style and colour options (see here if you haven’t already explored our range of security doors), it’s time to finalize your hardware choices and ensure you make the correct decision to protect your home.

What’s the difference between a single lock and a three-point lock?

When choosing hardware for your security door, it’s important to know what the difference is between a single lock and three-point lock and what impact each lock can have on your home security.

  • A single lock is a basic locking system, with just one central locking point. The locking mechanism is usually located in the middle of the door, just above or below the main door lock. Its mechanism allows the door to be opened or closed from inside the property without using a key, but a key is necessary for access from the outside.
  • A three-point lock is a more secure locking system, consisting of three locking points connected to an internal rod inside the door frame. The locking points are usually positioned at the top, middle and bottom of the rod. When a key is turned in the lock, all three locking points are engaged, effectively immobilizing the door, ensuring it remains securely close at the top, bottom and central point of the door frame.

How does a three-point lock work?

For customers seeking to enhance their home security, a three-point locking system is a sophisticated way to add an extra level of protection to a security door. A three-point lock

consists of three locks, so as soon as the door is closed, the upper and the lower latches engage automatically acting as deadbolts and increasing the security of the door. The central lock is engaged simply by turning the key.

A three-point locking mechanism allows the door to be locked from inside without using a key, but from the outside a key must be used to gain access. Because it locks at three points of the door, a three-point lock provides significantly improved security. 

Are three-point locks really worth it?

Yes, absolutely. Simply put, three-point locks are significantly more secure than a single lock. Three-point locks are more expensive than single-point locks, and can be slightly more labour-intensive to install, but they also provide significantly more protection to your property. Not all homeowners will choose to add a three-point lock to their security door but, if the protection of your home is paramount, a quality three-point lock is the best choice for your security door.

Don’t forget that an incorrectly installed locking system will weaken the overall security of your entrance and potentially render the security door ineffective. For installation options, or to book a professional, click here.

Make your home a more difficult target for burglars

Australian security standards require a three-point lock system to be installed in order for a door to be considered to be a security door. In order to comply with Australian security standards, a security door must also be “jimmy” resistant, meaning the lock must prevent the door being plied open. A single lock mechanism is much simpler for a burglar to force entry through because it only has a single lock. Thieves can break in by inserting a tool to ply the door open by forcing the frame to warp and render the lock useless. Usually, when a door is kicked in during a robbery, it’s not the door that breaks – it’s the door frame.

 A three-point lock effectively reinforces the door and stops burglars gaining entry. Most break-ins require some degree of force so a quality security door and locking system is an effective deterrent.
