Single-Cylinder Deadbolt

Ideal for residential doors, this type of deadbolt offers effective protection against unauthorized entry. Its straightforward design and easy installation make it a popular choice for homeowners seeking a reliable and straightforward security solution. Discover the benefits and considerations of the Single-Cylinder Deadbolt to make an informed decision for your home.

Double-Cylinder Deadbolt

The Double-Cylinder Deadbolt offers an additional layer of security by requiring a key for both sides of the door. This design prevents intruders from easily unlocking the door even if they break a nearby window. While providing heightened protection, it's important to consider safety measures, as it can pose challenges during emergencies when a key might be needed for quick exit. This deadbolt type is often recommended for doors with glass panels to prevent intruders from reaching inside to unlock. Explore the features and considerations of the Double-Cylinder Deadbolt to determine if it's the right choice for balancing security and safety in your home.

Mortise Deadbolt

A mortise deadbolt is a robust and secure door locking mechanism that is embedded, or mortised, into the door itself. This type of deadbolt provides enhanced protection against forced entry due to its design, which makes it more resistant to tampering. The mortise deadbolt is typically installed within the door, offering a sleek and streamlined appearance while maintaining a high level of security. Its construction involves a complex system of components, including a heavy-duty bolt that extends into the door frame, ensuring reliable protection for residential or commercial spaces.

Rim Deadbolts

Rim deadbolts are key-operated locks designed for external doors, providing an additional layer of security. Mounted on the surface of the door, these deadbolts feature a horizontal locking mechanism that engages with the door frame. This design facilitates straightforward installation and is often used as a supplementary lock. Rim deadbolts are known for their simplicity and durability, offering effective protection against unauthorized entry. Their user-friendly nature and reliability make them a popular choice for residential and commercial applications, enhancing overall security measures for exterior doors.

Vertical Deadbolts

A vertical deadbolt is a type of door lock that operates with a vertical bolt mechanism. Unlike traditional horizontal deadbolts, the bolt in a vertical deadbolt moves vertically into the door frame, enhancing security. This design provides an additional layer of protection against forced entry, as the bolt engages more deeply into the strike plate. Vertical deadbolts are often chosen for their robust construction and resistance to tampering. Their installation typically involves placing the lock above the doorknob, offering reliable security for both residential and commercial doors.

What to Consider When Choosing a Deadbolt Lock

When selecting a deadbolt lock, several factors should be considered to ensure optimal security for your property. Firstly, examine the lock's grading, typically measured by the ANSI (American National Standards Institute). Higher grades indicate greater durability and resistance to tampering. Consider the type of deadbolt - options include single-cylinder (keyed on one side, thumb turn on the other) and double-cylinder (keyed on both sides). Assess the material and finish for durability and aesthetics, and confirm that the lock complies with local building codes. Additionally, prioritize features like drill resistance and anti-pick technology for enhanced security. Finally, professional installation is crucial for the lock's effectiveness.

DIY Vs. Hiring a Pro

Choosing between DIY and hiring a professional for tasks like installing deadbolt locks involves weighing various factors. DIY projects provide cost savings and a sense of accomplishment, but may lack the expertise a professional brings. Installing a deadbolt requires precision to ensure proper alignment and security. Professionals possess the necessary skills to handle complexities and ensure compliance with safety standards. On the other hand, DIY enthusiasts can benefit from learning valuable skills and customizing installations. Consider factors such as experience, time constraints, and the complexity of the task when deciding between a DIY approach and hiring a pro for deadbolt lock installation. So, the average cost to hire a locksmith is about $150.

  • What Deadbolt Grade Should I Choose?

    Consider the ANSI grading system, which ranges from Grade 1 (highest) to Grade 3. Choose a deadbolt with a grade that aligns with your security needs. Higher grades offer better durability and resistance to tampering.

  • Single-Cylinder or Double-Cylinder: Which is Safer?

    Single-cylinder deadbolts have a key on one side and a thumb turn on the other, while double-cylinder deadbolts have keys on both sides. The choice depends on your preference and local building codes. Double-cylinder locks may enhance security but can pose safety concerns during emergencies.

  • Can I Install a Deadbolt Myself or Should I Hire a Professional?

    While DIY installation is possible, hiring a professional ensures precise placement, compliance with safety standards, and proper functioning. Consider your level of expertise, time constraints, and the complexity of the installation when deciding between a DIY approach and professional assistance.

5 Signs It’s Time to Replace Your Home Door Locks

Wondering if it's time to replace your home door locks? Discover 5 critical signs your locks may be failing and how timely upgrades can protect your home and loved ones.

A key fob is a small yet powerful device that provides remote access to your car. But if you find yourself constantly replacing its battery, it’s not just an inconvenience—it could signal an underlying issue. Let’s explore why your key fob battery might be draining faster than it should and what you can do about it. How to Open a Car With Dead Battery and Locked Doors 1. Constant Signal Communication Key fobs use radio frequency (RF) signals to communicate with your vehicle. Some models are designed to stay in continuous communication with your car, especially those with keyless entry or push-button start systems. This “always-on” signal drains the battery over time. Tip: Keep your key fob away from your car when not in use. If it stays close—like in a nearby hallway or garage—the fob and car may constantly "ping" each other, draining the battery faster. 2. Faulty Buttons or Internal Damage Sticky or worn-out buttons can remain slightly pressed, even when the key fob appears untouched. This constant pressure can force the device to send signals nonstop, causing rapid battery drain. What to do: Check for any stuck buttons or visible cracks. If the fob has been dropped or exposed to moisture, internal damage might be the culprit. Replacing the casing or getting it inspected can help. 3. Low-Quality Replacement Batteries Not all batteries are created equal. If you recently replaced the battery and it’s still draining quickly, a cheap or expired cell might be the reason. Solution: Always choose high-quality, brand-name coin cell batteries. Check the expiration date before buying, even if the packaging is sealed. 4. Extreme Temperature Exposure Hot summers or freezing winters can impact the performance of lithium coin batteries. If you leave your key fob in your car, especially in the cupholder or dashboard, it may be exposed to extreme temperatures that drain the battery. Fix: Store your key fob indoors when you’re not driving. Avoid leaving it in the car for extended periods. 5. Old Age of the Key Fob If your key fob is several years old, its internal components—especially the circuit board—may begin to wear down. Aging electronics are less efficient, which can lead to faster battery consumption. Tip: If your key fob is older than 5-7 years and constantly draining batteries, it may be time for a replacement or reprogramming. 6. Interference from Other Electronic Devices In some cases, nearby electronic signals—like those from Wi-Fi routers, smart home devices, or even other key fobs—can interfere with the fob’s signal. This interference can cause the fob to work harder to maintain a connection, draining the battery faster. Suggestion: Try storing your fob in a different location away from these devices, especially overnight. Can You Program a Transponder Key Without a Locksmith?  Final Thoughts A fast-draining key fob battery is more than just a minor nuisance—it could be a symptom of a deeper issue. Whether it’s excessive communication, faulty buttons, or environmental exposure, identifying the cause can help you fix it for good. If the problem persists even after battery replacement, it’s best to consult an automotive locksmit h or dealership for a full key fob diagnosis.
