Why a Double Keyed Door Knob is Necessary
From my experience, having a double keyed door knob adds an important layer of security that a single keyed knob simply can’t provide. With both sides requiring a key to unlock, I feel much safer knowing that no one can easily open the door from the inside without the right key. This is especially useful in situations where I want to prevent unauthorized access, even if someone is inside the house.
Another reason I find double keyed knobs necessary is for privacy and control. In my home office, for example, I can lock the door from either side, ensuring that my work remains undisturbed. It’s a great way to maintain boundaries and keep my space secure, whether I’m inside or outside the room.
Overall, the double keyed door knob gives me peace of mind. It’s a simple upgrade that enhances security and control, which is why I consider it an essential feature for certain doors in my home.
My Buying Guides on Double Keyed Door Knob
When I decided to upgrade the security of my home, I came across double keyed door knobs. After some research and personal experience, I want to share what I’ve learned to help you make an informed choice. Here’s my step-by-step guide on buying the right double keyed door knob for your needs.
What Is a Double Keyed Door Knob?
A double keyed door knob is a lock that requires a key to open from both the inside and outside. Unlike traditional locks with a thumb turn or button on the inside, this type offers enhanced security because no one can unlock the door without a key, even from inside.
Why I Chose a Double Keyed Door Knob
I wanted extra security for my front door since it faces the street. The double keyed mechanism ensures that even if someone tries to unlock it from inside, they need a key. This is especially useful if you have roommates or tenants, or if you want to prevent accidental unlocking.
Things to Consider Before Buying
1. Security Level
I looked for knobs with strong deadbolts and hardened steel inserts. Some models are rated for high security and are pick-resistant, which was important to me.
2. Key Type and Compatibility
I checked whether the lock uses standard keys or if it requires special key blanks. Also, I made sure the keys could be easily duplicated if needed.
3. Door Thickness and Size
My door was about 1.75 inches thick, so I confirmed the knob would fit. Double keyed knobs come in different sizes, so measuring your door is crucial.
4. Material and Finish
I wanted a knob that matched my door aesthetics and stood up to weather conditions. Brass and stainless steel finishes are popular for durability and style.
5. Ease of Installation
I chose a model that came with clear instructions and all the necessary hardware. If you’re not handy, consider professional installation.
Benefits I Experienced
- Improved security with key control on both sides
- Peace of mind knowing no one can unlock the door without a key
- Durable construction that withstands daily use
Potential Drawbacks to Keep in Mind
- You always need to carry a key to get out, so losing keys can be problematic
- In emergencies, unlocking the door might take longer
- Slightly higher cost compared to standard knobs
My Final Tips
If you prioritize security above all, a double keyed door knob is a great investment. Just be sure to keep spare keys in safe places and consider who will have access. Also, check local fire safety codes to ensure this type of lock is allowed in your area.
I hope my experience helps you choose the perfect double keyed door knob for your home!
