Choosing the Right Lock


When it comes to ensuring the security of our homes, choosing the right lock is of utmost importance. Three key options to consider are deadbolt locks, mortise locks, and security bar/brace.

Deadbolt locks provide maximum security by requiring a key to unlock from both the inside and outside, making them highly resistant to forced entry.

On the other hand, Mortise locks are known for their durability and strength, as they are embedded into the door itself.

Lastly, security bar/brace systems offer additional protection by reinforcing the door frame and preventing it from being kicked in.


Deadbolt locks


Double-cylinder deadbolts provide maximum security by requiring a key to lock and unlock the door from both sides. These types of locks offer enhanced protection against break-ins as they prevent intruders from simply turning a knob or lever to gain access.

Here are three key points to consider when it comes to double-cylinder deadbolts:

  1. Keyless entry: With double-cylinder deadbolts, you’ll always need a key to enter or exit the door, adding an extra layer of security. However, it’s important to keep the key within reach in emergencies.
  2. Lock maintenance: Regularly inspect the condition of your double-cylinder deadbolt and perform any necessary maintenance. Lubricate the lock to ensure smooth operation and check for any signs of wear or damage.
  3. Key duplication and lock installation: When duplicating keys for double-cylinder deadbolts, ensure you only trust reputable locksmiths or hardware stores. Additionally, having your deadbolt professionally installed is crucial to guarantee proper functioning and optimal security.


Mortise locks


For maximum security, reinforce the strike plate area of your mortise lock to ensure strength and durability.

There are a few key steps to follow when it comes to mortise lock installation. First, make sure the mortise pocket is aligned correctly and deep enough to accommodate the lock body. Next, attach the lock body to the door using the provided screws. Once the lock is securely in place, test the operation of the latch and deadbolt to ensure smooth functioning.

Troubleshooting mortise locks can involve checking for any loose screws or misaligned components.

One of the advantages of mortise locks is their robust construction, which makes them more resistant to forced entry. Additionally, upgrading to keyless mortise locks can offer convenience and added security. With their sleek design and advanced technology, keyless mortise locks provide a modern and secure solution for your home or business.


Security bar/brace


The security bar/brace provides additional protection for your door. It is a simple yet effective device that can be easily installed to reinforce the security of your entryway.

Here are three key reasons why you should consider using a security bar/brace:

  1. Door reinforcement: Placing the security bar/brace across your door adds strength and stability to the door frame, making it more difficult for intruders to force their way in.
  2. Window security: Some security bars/braces also come with an adjustable feature that allows you to secure your windows. This provides an extra level of protection against potential break-ins.
  3. Home security tips: While a security bar/brace is an excellent addition to your home security measures, it is essential to remember that it is just one part of a comprehensive security system. Consider combining it with other security features such as alarm systems, security cameras, and regular inspections of your locks and doors to ensure maximum protection for your home.

Installing the Lock


Position the deadbolt at least 1+ inches away from the edge of the door for maximum security.

To install the lock on your French doors, measure accurately to determine the ideal placement. Once you have the measurements, use a drilling template or a level to mark where the holes should be drilled on the door and frame.

Carefully drill the holes, making sure they are correctly aligned. Next, attach the strike plate to the door frame, ensuring it is securely in place.

Test the lock’s functionality by turning the key and operating the thumb turn. If you encounter any issues, such as difficulty turning the key or the lock not latching correctly, troubleshoot by adjusting the strike plate or checking for any obstructions.

Regularly inspect the lock to ensure it is in good condition and functioning properly.

Additional Security Measures


To maximize security, reinforce the strike plate area and regularly inspect the condition and locks. Here are three additional security measures you can take to enhance the safety of your French doors:

  1. Install security cameras: Installing security cameras near your French doors can provide visual surveillance and deter potential intruders. They allow you to monitor any suspicious activity and provide evidence in case of a break-in.
  2. Consider alarm systems: Alarm systems can provide an extra layer of protection by alerting you and the authorities in case of a breach. Choose a system specifically designed for French doors to ensure proper coverage.
  3. Use motion sensor lights: Installing motion sensor lights near your French doors can help deter intruders by illuminating the area when motion is detected. This added visibility can discourage break-ins and make your home less vulnerable to burglaries.

By implementing these additional security measures, along with reinforced door frames and secure locks, you can significantly enhance the security of your French doors and provide peace of mind for you and your family.

However, it is essential to remember that security is an ongoing process that requires regular maintenance and attention. Routine lock inspection is crucial to ensure your locks are in proper working condition and free from potential vulnerabilities. Additionally, adequate lock maintenance, such as lubricating the lock mechanism and cleaning any debris, can help prolong the lifespan of your locks and ensure their effectiveness.

Moreover, storing spare keys securely is equally essential. Consider using a secure key storage solution, such as a lockbox or a key safe, to prevent unauthorized access.

Lastly, if you want to enhance the security of your French doors further, you may consider installing security glass. Security glass is designed to resist break-ins and provide extra protection against forced entry attempts.
