Are Double Keyed Deadbolt Locks Safe? Understanding Their Safety and Usage


Introduction: Unlocking the Truth About Double Keyed Deadbolt Locks

Did you know that double keyed deadbolt locks can significantly enhance your home security but might also pose a unique risk?

As homeowners, we're constantly seeking ways to fortify our sanctuaries. Yet, the dilemma of choosing the right lock—balancing safety and accessibility—can be daunting.

Enter the double keyed deadbolt lock—a contender in the realm of home security solutions. But before you make the switch, it's crucial to understand both the benefits and drawbacks.

In this post, we’ll explore what double keyed deadbolt locks are, their pros and cons, legal considerations, and tips for safe use. By the end, you'll be equipped to decide if this lock type suits your needs or if alternatives might be more appropriate.


Step #1: Understanding Double Keyed Deadbolt Locks

What They Are: Double keyed deadbolt locks are security devices that require a key to open from both sides of the door. Unlike single-cylinder deadbolts, which have a thumb turn on the inside, these locks only operate with a key.

Real-World Example: Imagine having a door with a nearby window. A single-cylinder lock might be vulnerable if an intruder breaks the glass and reaches in to unlock the door. A double keyed deadbolt mitigates this risk by requiring a key even from the inside.


Step #2: The Pros of Double Keyed Deadbolt Locks

Enhanced Security: The primary advantage of double keyed locks is their superior security. They are especially beneficial for doors with adjacent glass panels.

  • Intruder Deterrence: Prevents easy access by breaking glass and reaching in.
  • Child Safety: Provides control over exits, useful in homes with young children.

Case Study: A family living in a bustling city neighborhood replaced their front and back door locks with double keyed deadbolts. They reported a heightened sense of security, particularly appreciating the control over who could exit the home.


Step #3: The Cons of Double Keyed Deadbolt Locks

Safety Concerns: Despite their security benefits, these locks can pose safety risks, especially in emergencies.

  • Fire Hazard: In case of a fire, finding the key to unlock the door can be a critical delay.
  • Accessibility Issues: Can be problematic for quick exits during emergencies.
  • Legality: In some regions, building codes or fire regulations prohibit their use on certain doors.

Example: Consider a situation where a family has to evacuate quickly due to a fire. If the key is misplaced, the delay could be dangerous.


Regulations: Before installing a double keyed deadbolt, check local building codes and fire safety regulations. Some areas restrict their use due to the potential hazard they pose during emergencies.

Consult Professionals: Always consult with a certified locksmith or a door installation professional to ensure compliance with local laws and standards.


Step #5: Tips and Reminders for Safe Use

  1. Key Management: Always have keys readily accessible near the door but out of reach from potential intruders.
  2. Emergency Preparedness: Conduct regular drills to ensure everyone knows how to exit safely.
  3. Consider Alternatives: Evaluate if a double-cylinder lock is necessary or if a single-cylinder with reinforced glass is adequate.
  4. Regular Maintenance: Ensure locks are well-maintained to prevent jamming.

Conclusion: Making the Right Choice for Your Home

Choosing the right lock involves balancing security needs with safety considerations. Double keyed deadbolt locks offer enhanced security but come with significant safety trade-offs.
