Why a Double Cylinder Door Knob Keyed Both Sides Is Necessary
From my experience, having a double cylinder door knob keyed on both sides is crucial for enhanced security. Unlike a single cylinder lock, which can be unlocked from the inside without a key, the double cylinder design requires a key on both sides. This means that even if someone breaks a nearby window or glass panel, they can’t simply reach in to unlock the door from the inside. This added layer of protection gives me peace of mind knowing my home is much harder to breach.
Another reason I find double cylinder locks necessary is for controlling access in specific situations. For instance, in homes with children or elderly family members, it prevents accidental unlocking or opening of the door from the inside without a key. This reduces the risk of someone wandering outside unsupervised or an intruder gaining easy entry. Overall, the double cylinder door knob strikes a balance between safety and security that I’ve come to appreciate in my own home.
My Buying Guides on ‘Double Cylinder Door Knob Keyed Both Sides’
When I decided to upgrade the security of my home, I found that a double cylinder door knob keyed both sides was an excellent choice. It offers enhanced safety by requiring a key to open the door from either side. If you’re considering this type of lock, here’s what I learned along the way to help you make an informed decision.
Understanding What a Double Cylinder Door Knob Is
A double cylinder door knob has keyholes on both the interior and exterior sides of the door. Unlike a single cylinder lock that only requires a key from the outside and a thumb turn on the inside, this type requires a key every time you want to open it. I chose this for doors with glass panels or windows nearby, where someone could potentially break the glass and reach in to unlock a single cylinder lock.
Why I Chose a Double Cylinder Lock
The main reason I went for a double cylinder lock was to prevent unauthorized entry through breakable glass near my door. It gave me peace of mind knowing that even if someone broke the glass, they couldn’t simply turn the lock from the inside without a key. However, I also considered the potential safety risks, like needing a key to exit quickly in an emergency, so I made sure everyone in my household had easy access to a key.
Key Factors to Consider Before Buying
- Safety Codes and Regulations: I first checked local building codes because some areas restrict or regulate double cylinder locks due to safety concerns during emergencies.
- Key Management: Since you need a key on both sides, I ensured I had multiple copies for family members and emergency situations.
- Door Material and Thickness: Not all locks fit every door. I measured my door thickness and chose a lock compatible with it.
- Durability and Finish: I picked a lock with a weather-resistant finish since my door is exposed to outdoor elements.
- Ease of Installation: I looked for models with straightforward installation guides since I planned to install it myself.
- Lock Quality and Brand Reputation: I read reviews and chose a lock from a reputable brand known for reliability and security.
My Installation Tips
Installing a double cylinder door knob can be a bit trickier than a standard lock because of the dual key mechanism. I recommend:
- Carefully following the manufacturer’s instructions.
- Using proper tools like a screwdriver, drill, and measuring tape.
- Double-checking that the key works smoothly on both sides before finalizing installation.
Maintenance and Usage Advice
To keep my lock functioning well, I:
- Regularly lubricate the keyholes with graphite powder or a silicone-based lubricant.
- Avoid using oil-based lubricants that attract dirt.
- Keep spare keys in secure but accessible places.
- Test the lock periodically to ensure smooth operation.
Final Thoughts
Choosing a double cylinder door knob keyed both sides is a great security upgrade for doors with glass nearby. However, it’s essential to balance security with safety and convenience. Make sure to check local regulations, have keys accessible for everyone in your household, and choose a high-quality lock that fits your door perfectly. Following these steps made me confident in my purchase and improved the security of my home significantly.
