Securing Exterior Doors for Enhanced Safety
Protecting your home from intruders is paramount, and securing your exterior doors is crucial. Here are some robust measures to ensure the safety of your abode:
Deadbolt Locks: The Ultimate Barrier
Deadbolts offer an unparalleled level of security compared to spring-loaded latches. They feature a thick, solid bolt that extends deep into the door frame, preventing forced entry. Deadbolts come in various types, including single-cylinder (key required on both sides), double-cylinder (key required from both sides), and electronic models. Opt for a deadbolt with a minimum bolt length of 1 inch and a sturdy strike plate securely fastened to the door frame. Additionally, consider installing a deadbolt with a protective shroud to shield the bolt from sawing or tampering.
When selecting a deadbolt, pay attention to its ANSI Grade rating. Grade 1 locks are the most secure and withstand the most force. Grade 2 locks offer a good balance of security and affordability, while Grade 3 locks are suitable for less vulnerable areas such as interior doors.
The placement of your deadbolt is also crucial. Install the deadbolt at least 30 inches above the ground to deter attackers from reaching it easily. Consider installing deadbolts on both the hinged side and the inactive side of the door for maximum protection.
| ANSI Grade | Security Level |
|---|---|
| 1 | Highest |
| 2 | Medium |
| 3 | Lowest |
Utilizing Door Locks for Optimal Protection
Choosing the Right Lock
Selecting the appropriate lock is crucial for maximizing door security:
- Deadbolts: Deadbolts provide the highest level of security, anchoring into the door frame and providing resistance against force and drilling.
- Keyed Locks: Traditional keyed locks are still effective and offer convenience, but they can be susceptible to picking and bumping attacks.
- Smart Locks: Smart locks offer remote access, automation, and integration with home security systems, enhancing convenience and security but requiring reliable internet connectivity.
Installing and Maintaining Locks
Proper installation and maintenance are equally important for optimal protection:
- Proper Installation: Ensure the lock is securely installed into the door, with the strike plate firmly attached to the door frame.

| Bolt Throw | Choose a lock with a longer bolt throw distance, which provides more resistance against forced entry. |
Techniques to Lock Doors from the Outside
Using a Key or Keycard
The traditional method of locking a door from the outside is to use a key or keycard. Simply insert the key into the lock and turn it clockwise. For keycards, swipe the card through the designated reader, and the door will unlock. This method is secure and straightforward but requires you to have the physical key or keycard with you.
Using a Deadbolt
A deadbolt is a more secure locking mechanism than a standard lock. It has a bolt that extends into the door frame, making it more difficult to force open. To lock a door with a deadbolt, insert the key into the lock and turn it clockwise. Then, push the bolt into the door frame by turning the knob or lever. Some deadbolts also have a thumbturn on the inside, allowing you to lock and unlock the door from the inside without a key.
Using a Smart Lock
Smart locks offer a variety of convenient features, including the ability to lock and unlock your door remotely using a smartphone app. They can also be integrated with other smart home devices, such as security cameras and doorbells.

| Keypad Lock: | Install a keypad lock for keyless entry, eliminating the need for keys and reducing the risk of lockouts or unauthorized access. |
Essential Tools for Effective Door Locking
Ensuring the safety and security of your property requires a robust locking system for your doors. Here are some essential tools that can assist you in this endeavor:
– Lock Picks
Lock picks are thin, metal tools used to manipulate the internal mechanisms of a lock, allowing you to open a door even when you don’t have the key. They are commonly employed by locksmiths and law enforcement, but can also be used by individuals with the necessary skill and knowledge.
– Bump Keys
Bump keys are specially designed keys that can be inserted into a lock and struck with a hammer, causing the pins inside the lock to move and disengage. This method can be effective in opening certain types of locks quickly and quietly, making them a favored tool among burglars.
– Drill
A drill can be used to bore a hole into the side of a lock cylinder, which allows you to access and manipulate the internal components. This technique is often used when lock picking or bump key methods are unsuccessful.

Troubleshooting Common Door Locking Issues
1. Door Won’t Lock
– Check if the door is properly aligned with the frame. Misalignment can cause the strike plate to not line up with the latch, preventing it from engaging.
– Ensure the strike plate is securely fastened to the door frame. A loose strike plate can cause the latch to miss it or engage too weakly.
– If the latch is damaged or bent, it may not be able to fully engage with the strike plate. Inspect the latch for any issues and consider replacing it if necessary.
2. Door Locks Too Easily
– Adjust the strike plate to ensure the latch fully engages when the door is closed. A slightly retracted strike plate can allow the latch to engage without fully locking.
– Lubricate the latch and strike plate. Friction can cause the latch to stick, making it easier to unlock. Apply a few drops of oil or graphite powder to the moving parts for smoother operation.
– Inspect the lock cylinder for any signs of wear or damage. Worn or damaged cylinders can allow the lock to be picked or manipulated more easily. Consider replacing the lock if it shows signs of compromise.
3. Key Won’t Turn
– Make sure the key is fully inserted and aligned correctly. If the key is tilted or not inserted far enough, it may not engage the pins properly.
– Check for any debris or dirt inside the lock cylinder. Dust, dirt, or other particles can clog the mechanism and prevent the key from turning. Use a compressed air can or a small brush to clean out the cylinder.
– If the key is still stuck, try using a penetrating lubricant like WD-40. Insert the lubricant into the lock cylinder and wait a few minutes before attempting to turn the key again.
4. Door Won’t Unlock
– Ensure the correct key is being used. Different locks require specific keys, and using the wrong one will not unlock the door.
– Check the door handle. If it’s loose or broken, it may not fully engage the unlocking mechanism. Tighten or replace the handle to ensure it functions properly.
– Inspect the latch for any damage or obstructions. Debris or wear can prevent the latch from retracting when the key is turned. Clean and inspect the latch for any issues.
5. Lock Won’t Latch
– Adjust the strike plate to ensure the latch engages fully when the door is closed. A slightly misaligned strike plate can cause the latch to bypass it altogether.
– Clean the latch and strike plate thoroughly. Dirt and debris can accumulate over time, inhibiting the latch from securely engaging. Use a cloth or brush to remove any particles.
– Check for any obstructions in the door frame or around the door edge. Even minor obstacles can prevent the latch from engaging properly. Inspect the area and remove any potential hindrances.
6. Key Breaks in Lock
– Use a pair of pliers or tweezers to grasp the broken key and carefully pull it out. If the key is stuck deep inside the cylinder, it may be necessary to use a needle-nose plier to reach it.
– Insert a lubricant like WD-40 into the lock cylinder to help loosen any remaining fragments. Wait a few minutes before attempting to remove the key pieces.
– If the broken key cannot be removed, it may be necessary to call a locksmith. A professional locksmith will have specialized tools to extract the broken key and repair or replace the lock as needed.
Additional Considerations for Enhanced Security
1. Use a Deadbolt Lock
Deadbolt locks are more secure than spring-loaded locks because they require a key to operate from both sides. This prevents someone from simply breaking a window and reaching in to unlock the door.
2. Install a Security Bar
Security bars can be placed across the inside of a door or window to prevent it from being forced open. They are especially useful for doors and windows that are located in vulnerable areas, such as a ground-floor window or a door that leads to a fire escape.
3. Use a Door Chain
Door chains allow you to open the door slightly to see who is outside without giving them the ability to enter. This is a good option for when you need to answer the door but are not sure who is on the other side.
4. Install a Door Reinforcement Plate
Door reinforcement plates are metal plates that are installed on the inside of the door frame. They help to strengthen the door and make it more resistant to forced entry.
5. Install a Peephole
A peephole allows you to see who is outside before you open the door. This can help you to avoid opening the door to strangers or uninvited guests.
6. Use Smart-Home Technology
Smart-home technology can be used to enhance the security of your home. For example, you can install a smart lock that can be controlled with your smartphone or voice assistant. This allows you to lock and unlock your door remotely, and you can also receive notifications when the door is opened or closed.
7. Maintain Your Locks
Regular maintenance is essential for keeping your locks in good working condition. This includes cleaning and lubricating the locks, and inspecting them for any signs of damage or wear. If you notice any problems with your locks, it is important to have them fixed as soon as possible.
| Lock Type | Security Level | Cost |
