Why a Double Keyed Door Knob is Necessary
As someone who values security in my home, I’ve found that a double keyed door knob is an essential feature for several reasons. First and foremost, it provides an extra layer of protection. Knowing that both the inside and outside of my door require a key to unlock gives me peace of mind. It’s particularly comforting when I’m home alone or during the night, as it minimizes the risk of unwanted entry.
Another significant reason I appreciate double keyed door knobs is their deterrent effect. When potential intruders see that a door has a double keyed lock, it signals that breaking in will be more complicated and time-consuming. In my experience, the less appealing a target looks, the less likely it is to be chosen. This added deterrence means I can feel more secure, whether I’m home or away.
Lastly, I’ve discovered that double keyed door knobs are incredibly useful in specific situations. For example, when I’m renting out a room or sharing my home with others, having a double keyed lock allows me to maintain control over access. I can provide keys to guests or tenants without worrying about them having a way to enter from the outside without my permission. This flexibility has made managing my living
My Buying Guide on Double Keyed Door Knob
When I set out to find the perfect double keyed door knob for my home, I quickly realized that there were several factors to consider. Having a double keyed door knob can provide an extra layer of security, especially for external doors. Here’s what I learned during my search, and I hope it helps you make an informed decision as well.
Understanding Double Keyed Door Knobs
First, let me explain what a double keyed door knob is. Unlike traditional door knobs that have a keyhole only on one side, a double keyed door knob features keyholes on both sides. This means that both the inside and outside of the door require a key to unlock it, which can be a significant advantage for security, especially in areas prone to break-ins.
Why I Chose a Double Keyed Door Knob
When I considered my options, I wanted a door knob that would provide peace of mind. I live in a neighborhood where security is a priority, and I felt that a double keyed door knob would deter potential intruders. Additionally, I liked the idea of having control over who could access my home, particularly in cases where I might be away for an extended period.
Key Features to Look For
- Material and Build Quality
- I quickly learned that the material of the door knob is crucial. I opted for a solid brass or stainless steel option because it not only looks elegant but is also durable against wear and tear.
- Security Ratings
- I researched various security ratings, such as ANSI (American National Standards Institute) grades. A grade 1 rating offers the highest level of security, so I made sure to choose a knob that met this standard.
- Key Compatibility
- It’s essential to consider the type of keys that come with the door knob. I wanted a system that allowed for rekeying in case I needed to change the locks in the future. Some brands offer rekeying kits, which can save me money and time down the road.
- Ease of Installation
- I’m not a professional handyman, so I looked for a model that was easy to install. Many double keyed door knobs come with clear instructions and the necessary tools, which made the process straightforward for me.
- Design and Aesthetic
- Lastly, I wanted a door knob that would complement my home’s decor. I found various styles and finishes, from modern to traditional, so I could pick one that matched my personal taste.
Pricing Considerations
As I browsed through options, I found that double keyed door knobs can vary significantly in price. I noticed that while more expensive models often offer superior security features and aesthetics, I could still find reliable options within a moderate budget. I set a price range for myself, which helped narrow down my choices without compromising on quality.
Where to Buy
I explored several places to purchase my double keyed door knob. Home improvement stores like Home Depot and Lowe’s had a wide selection, but I also found great options online through retailers like Amazon and Wayfair. Shopping online allowed me to read reviews and compare prices easily, which was a big plus.
Final Thoughts
In the end, choosing the right double keyed door knob was about balancing security, style, and budget. I’m happy with my decision and feel more secure in my home knowing I have an extra layer of protection. I hope my experiences and insights help you in your search for the perfect double keyed door knob! Happy shopping!
