What to Look for in Most Secure Deadbolts

Important criteria

  • High-quality materials
  • ANSI/BHMA Grade 1 Certification
  • Bump-proof design
  • Pick-resistant features
  • Drill-resistant components
  • Long-lasting durability

1.) Lock Grade Certification

When selecting the most secure deadbolts, it is crucial to look for locks that have a certification indicating their strength and durability. The ANSI/BHMA (American National Standards Institute/Builders Hardware Manufacturers Association) certification grades deadbolts on a scale from Grade 1 to Grade 3, with Grade 1 offering the highest level of security. Deadbolts with a Grade 1 certification have passed rigorous testing for cycles, resistance to impact, and forceful entry, making them suitable for both residential and commercial applications.

2.) Material and Build Quality

The material and build quality of the deadbolt play a significant role in its overall security. High-quality deadbolts are commonly made from solid metals such as brass, steel, or hardened steel alloys, which provide greater resistance against physical attacks like drilling or hammering. Additionally, a well-constructed deadbolt should have a reinforced strike plate and solid metal core without plastic parts to ensure maximum strength and reliability against forced entry.

3.) Key Control and Pick Resistance

Look for deadbolts that feature pick-resistant cylinders and offer key control to prevent unauthorized key duplication. Deadbolts with complex keyways and mechanisms like side bars or anti-drill pins provide added protection against lockpicking and bumping. Manufacturers who offer patented keyway designs or restricted key duplication services can further enhance the security of your lock, making it difficult for others to copy keys without proper authorization.

4.) Smart Lock Features

For those considering smart deadbolts, assess the encryption level and online security features of the device to protect against hacking. Smart deadbolts that offer features like two-factor authentication, secure Bluetooth or Wi-Fi connections, and automatic locking can enhance security while offering convenience. However, it is crucial to balance these technological advantages with the potential vulnerabilities they introduce, such as the risk of electronic lock failure or cyber-attacks.

Questions You Might Ask

When selecting a deadbolt, consider the lock's ANSI grade (Grade 1 being the highest and most secure), the type of deadbolt (single or double cylinder), the material it is made of (such as steel, brass, or zinc), the compatibility with your door thickness, and the ease of installation.
A single cylinder deadbolt is operated with a key from the outside and a thumb turn on the inside, while a double cylinder deadbolt requires a key to operate from both the outside and inside, offering enhanced security but potentially posing a safety issue in case of emergency egress.

How to Choose the Most Secure Deadbolts for Your Home

When it comes to home security, every detail matters, and choosing the right deadbolt for your doors can be the difference between an easy target and a safe haven. In this buying guide, we'll walk you through everything you need to know to select the most secure deadbolt that complements your security needs and gives you peace of mind.

Understanding Deadbolt Security Grades

When we talk about deadbolt security, the term 'grade' is crucial. Deadbolts are rated by the American National Standards Institute (ANSI) and can come in Grade 1, 2, or 3, with Grade 1 being the strongest. Grade 1 deadbolts are typically used in commercial spaces but are now becoming more common in residential settings due to their superior strength and resistance to break-ins.
Grade 2 deadbolts offer a fair amount of security and are often found in residential properties. They're a solid choice if you're balancing cost and security. Meanwhile, Grade 3 deadbolts provide minimal security and are best used in interior rooms rather than main entrances. Always prioritize a deadbolt's grade, especially for exterior doors, to ensure robust security.
Remember, while higher-grade deadbolts generally offer more protection, they must be properly installed to be effective. A poorly installed Grade 1 deadbolt might not provide the security it's capable of, so consider professional installation.

Key Features to Look For

Secure deadbolts should possess certain features that enhance their protective abilities. A solid core is one such feature, as it significantly hampers efforts to break through. Look for deadbolts with hardened steel cores or inserts to resist drilling attacks.
Another important feature is a deadbolt with a long throw, which is the length of the bolt that goes into the door frame. A longer throw means it's harder for intruders to force the door open. Anti-pick pins and intricate keyways increase difficulty for lock-picking, while a bump-resistant design helps prevent the lock from being forced open using 'bump keys', a common trick among burglars.
Lastly, don’t overlook the finishes and feels of the deadbolt. While aesthetics might not be as critical as security features, a deadbolt that looks sturdy can be a deterrent to potential intruders. Moreover, a finish that's resistant to corrosion and wear will ensure the lock lasts longer and stays reliable.

Smart Locks vs. Traditional Deadbolts

The advent of smart technology has introduced smart locks, which offer a blend of traditional security and modern convenience. With features like remote access, biometric entry, and user-specific codes, smart locks provide a new level of security. These locks typically integrate with home automation systems, allowing you to monitor and control them from anywhere via a smartphone app.
Traditional deadbolts, on the other hand, rely on physical keys, which can be lost or copied. Still, many homeowners prefer them for their simplicity and reliability. There are no batteries to replace or electronics to malfunction with a traditional deadbolt, leading to fewer points of potential failure.
Your choice between a smart lock and a traditional deadbolt should be guided by your lifestyle and preferences. If you're drawn to high-tech solutions and convenience, a smart lock might be the right fit. However, if you're more comfortable with a key-and-lock mechanism and seek a no-frills approach to security, a traditional deadbolt could serve you best.

Considerations for Installation and Compatibility

Before making a purchase, ensure that the deadbolt you choose is compatible with your door's thickness and has the correct backset size; this is the distance from the edge of the door to the center of the lock. Erroneous measurements can lead to deadbolts that don't fit or work improperly. If in doubt, consult with a locksmith or a skilled handyman.
Installation can influence the efficacy of your deadbolt. Even the highest-grade lock will underperform if installed incorrectly. Hiring a professional can add to the cost but is often worth the investment for the peace of mind and security it provides. To maintain warranty and ensure optimal performance, follow the manufacturer's instructions or seek professional help.
Lastly, be mindful that sometimes upgrading a deadbolt may necessitate modifications to your door or frame. Careful planning and consideration should be taken to make these changes without impacting the door's integrity. Since your deadbolt is only as secure as the door and frame it's attached to, reinforce those areas if needed to ensure comprehensive protection.
