In Australia, about 4,000 residential burglaries occur every day. That means every 15 seconds a home is being invaded. These stats alone are surely enough to scare you, and make you want to install a sturdy home security system right away.

Intruders are getting bold—and you need to be smart too to secure you, your family and your safe haven.

Installing a double-door lock system is a robust security solution to do just that. It has advanced security features you can’t find in your regular locking mechanism, giving you 24/7 protection and a peace of mind.

Understanding Double Door Locks

A double door lock is a locking mechanism that simultaneously protects two doors in a single entry and exit.

The double locks work together to enhance the security of your home, preventing forced entries.

Here are two common types of double-door locks:

Double Cylinder Deadbolt

Unlike the single-cylinder deadbolt lock, the double-cylinder deadbolt has a key that turns the lock on both sides. So, when you open the door, you will need a key to unlock both ends of the door, inside and outside.

This adds an extra layer of security, making it more elusive to pick. If a thief ever manages to break the window, they won’t still be able to move the knob to open it from the inside.

Smart Double Door Locks

A smart double door lock is a locking mechanism that works without a physical key. Instead, it uses a smartphone or a keypad to access doors from both inside and outside.

This leads to a more robust locking system that can withstand force entries, making it more difficult for any intruders.

Benefits of Installing a Double Door Lock

Enhanced Security Against Forced Entry

By having two locks operating together, housebreakers and crooks will have a very challenging time getting in. Even if they’re able to pick one lock, they will still have to unlock the other one. The complexity of this would deter them from breaking in.

Increased Convenience with Smart Locking Options

Smart double door locks have advanced features that keep tabs of anyone who enters and leaves your property, sending alerts instantaneously. You can even hand out virtual keys to family members or friends to give access.

This offers massive accessibility, enabling entry and security for homeowners from anywhere, anytime.

Aesthetic Appeal and Customisation Options

Double door locks are not just great at augmenting your home’s security; they can also enhance its visual appeal. This locking apparatus offers a sleek range of contemporary designs and customisable options that would certainly complement your sophisticated style.

From brass and antique bronze to stainless steel, there are different modish finishes that can match every aesthetic preference of your home.

Choosing the Right Double Door Lock

It is a daunting process to choose your double door lock. But you have to remember that when it comes to choosing your locking system, no one lock fits all.

Consider the following factors and then determine which double door lock is best for your home.

Security Ratings

Find a high-quality double-door lock with enhanced security features or grade 1 locks. These locks have a high ANSI rating, which means they are very difficult to breach, withstanding extreme physical force and wear.

Compatibility with Door Type

If you have wooden doors, you might need extra fortification. If you’re using glass, you need a compatible material, such as a mortise lock.

You have to assess your material and design, ensuring that your double door lock complements the size, setup and structure of your door.

Technology Features

Take into account the smart tech functionalities of your double door lock, such as the integration of your locking system with the rest of your smart home system.

Consider locks with auto-locking, voice control, and battery backup. These are necessary considerations as this would enhance control, functionality and convenience at all times.

Installation Process

With the right materials and a sprinkle of patience, installing a double-door lock becomes a manageable process.

Preparation

To make your job easier and save time, prepare all the tools you need for installation first before jumping on your project.

Screwdriver
Drill
Measuring tape
Chisel
Hammer
Pencil

Along with the materials, maintain safety precautions.

Wear gloves to protect yourself from any injury.
Ensure the power tools are safe and use them carefully.
Check the alignment of the lock and make sure it’s not too tightly screwed to ensure proper functioning.

Step-by-Step Installation

Removing the Old Lock (if applicable)

Unscrew the old lock—use a screwdriver and remove the deadbolt, latch and handle. Then, take off the strike plates or any other fastener that holds the locking mechanism to the door frame.

Measuring and Marking the Installation Points

With the measuring tape, mark the exact installation points on both doors, making sure it’s precisely aligned.

Installing the Lock Body and Securing it Properly

Place the lock body into the installation points and secure it properly with screws, checking that it’s level with the door’s surface.

Testing the Lock Functionality

Check the lock several times and ensure both doors are functioning together without any resistance.

Maintenance Tips for Double Door Locks

Here’s what you should do to not compromise the performance of your locking system over time:

Regular Cleaning

Your locks will collect dust and dirt, eventually affecting their performance. To prevent jamming or congestion, wipe your locks regularly with a slightly wet cloth.

For the inner components, use compressed air to blow out dust. However, avoid using any strong chemicals, as they can affect your hardware.

Regular Checks

Inspect your locks regularly for any signs of damage like rust or dents. Try testing the locking mechanism several times and see if there’s any unusual resistance.

You can also hire a professional locksmith—experts who can assess issues that are not obvious to you.

Lubrication Techniques

Lubrication is essential for a seamless lock operation.

With time, your double door lock will be susceptible to wear. In that case, apply a lubricant for any moving component in your locking system every year to maintain high performance and prolong its lifespan.

Upgrading Technology

Improve your double-door lock by reinforcing a secondary security feature.

For smart locks, we advise you to do software updates. With an upgrade, your locking system can determine vulnerabilities and add a new functionality that can improve control and speed.

Conclusion

A double door lock is an effective and attractive way to strengthen your home’s security against unathorised entries. It boasts a reinforced mechanism and aesthetic designs that feature ease of use. You can even incorporate upgrades to fortify your property’s protection.

While you can choose to work on your double door locks yourself, we recommend consulting professionals for installation and maintenance.
