Why an Extra Door Lock from Inside is Necessary
From my experience, having an extra door lock inside my home has made me feel significantly safer and more secure. Sometimes, relying on just the main lock isn’t enough, especially in situations where I need that additional layer of protection. It gives me peace of mind knowing that even if someone tries to force entry, there’s an extra barrier that makes it much harder for them to get in.
Also, having a secondary lock inside is incredibly useful for privacy. Whether I’m working late, sleeping, or just need some uninterrupted time, I can lock the door easily without worrying about accidental openings. It’s a simple addition, but it truly enhances both my safety and comfort in my own space.
My Buying Guides on ‘Extra Door Lock From Inside’
When I decided to add an extra door lock from inside my home, I wanted to ensure maximum security without sacrificing convenience. Here’s what I learned through my experience, and I hope it helps you make the right choice.
Why I Needed an Extra Door Lock
Even though my main door had a standard lock, I felt that an additional lock would give me peace of mind—especially during the night or when I was away. Extra locks can deter break-ins and provide an extra layer of protection.
Types of Extra Door Locks I Considered
- Deadbolt Locks: These are sturdy and provide strong security. I liked that they bolt directly into the door frame, making forced entry difficult.
- Chain Locks: These allow the door to open slightly while still secured. I found them useful for checking visitors but less secure overall.
- Slide Bolts: Simple and easy to install, these locks slide into place to secure the door from the inside.
- Bar Locks: These add resistance by placing a bar across the door, which I found very effective for sliding or French doors.
- Smart Locks: These offer keyless entry and remote control via an app. I considered these for convenience but wanted a mechanical backup.
What I Looked For Before Buying
- Security Level: I prioritized locks with solid construction, preferably made from hardened steel or heavy-duty materials.
- Ease of Installation: Since I wanted to install it myself, I looked for locks that didn’t require professional tools or drilling into the door frame.
- Compatibility: My door is wooden, so I made sure the lock I chose was compatible with wood doors and fit the door thickness.
- Convenience: I wanted a lock that was easy to operate from the inside, especially in case of emergencies.
- Aesthetics: Since the lock would be visible, I preferred one that blended well with my door’s appearance.
My Installation Experience
I found that most extra locks come with clear instructions and all the hardware needed. I used a screwdriver and a drill for some screw holes. Measuring carefully before installation was crucial to ensure the lock aligned perfectly.
Maintenance Tips I Followed
To keep my extra door lock functioning smoothly, I regularly lubricate the moving parts with graphite or silicone spray. I also check screws and bolts to make sure everything stays tight and secure.
Final Thoughts
Adding an extra door lock from inside gave me a greater sense of security and control over who enters my home. If you’re considering one, think about the type of door you have, your security needs, and how much effort you want to put into installation. With the right lock, you can enhance your home’s safety without hassle.
