Upgrade Your Security By Installing a New Deadbolt

At Advanced Lock Service, we understand the importance of feeling safe and secure in your own home. That’s why we offer professional deadbolt sales and installation, ensuring you have the highest quality locks protecting your loved ones and belongings.

Why Choose a Deadbolt?

Deadbolts are an essential layer of security for any home, office, or commercial business. Unlike standard door knobs, deadbolts extend a bolt further into the door frame, providing a more substantial barrier against forced entry. 

Here are a few of the benefits of installing a new deadbolt lock or upgrading your existing deadbolt:

Enhanced Security: 

Deadbolts offer a significant security upgrade over standard door locks. Their robust design makes them highly resistant to forced entry.

Peace of Mind: 

Knowing your home is well-protected allows you to relax and feel secure.

High-quality deadbolts can increase your home’s resale value.

Choosing the Right Deadbolt for Your Needs.

Single Cylinder VS Double Cylinder Deadbolts:

Selecting the appropriate deadbolt lock is critical for effectively securing your home or business. Deadbolts offer an added layer of security, making it considerably more challenging for unauthorized individuals to gain access. Two primary options exist within the realm of deadbolts: single-cylinder and double-cylinder deadbolts.

Single Cylinder vs. Double Cylinder Deadbolt  The Key Differences:

Both deadbolts operate exactly the same from outside the door. The primary difference between single-cylinder and double-cylinder deadbolts is how you lock them from inside the door. 

A single-cylinder deadbolt uses a key on the outside for locking and unlocking but uses a “thumb turn” or turn lever on the inside for locking and unlocking. 

A double-cylinder deadbolt uses a key on both the outside and inside of the door to operate the lock. This is the main difference between these two types of deadbolts.

Here is a comparison list between single and double cylinder deadbolts:

Feature

Single Cylinder Deadbolt

Double Cylinder Deadbolt

Locking Mechanism

Requires a key on the outside and a thumb turn or lever on the inside.

Requires a key on both the outside and inside to lock and unlock.

Convenience

Easier and faster to exit in case of an emergency as no key is needed on the inside.

Provides added security but requires a key for both entry and exit, potentially slowing down emergency egress.

Security Considerations

Slightly less secure on the inside. Someone who breaks in through a window can easily exit the door with stolen items.

Offers enhanced security as keys are needed on both sides, making it more resistant to break-ins. Thieves can’t break a nearby window to reach in and unlock the door.

Recommended Use Cases

Typically used on doors where quick and easy egress is a priority, such as residential front doors.

Recommended for doors with glass panels or windows near the deadbolt. Also suitable for commercial properties and high-security applications.

Code and Regulations

Often complies with building codes and regulations for residential properties.

May not be permitted in some residential areas.

The Pros and cons of a double cylinder deadbolt

Pros:

  • Enhanced protection against break-ins: Double cylinder deadbolts increase security by requiring a key for the door’s interior and exterior sides. This design significantly reduces the risk of burglars gaining unauthorized access to your property. In particular, double-cylinder deadbolts excel at bolstering security on doors with glass panels or windows nearby, where the absence of a thumb turn on the interior side makes it difficult for intruders to break the glass and reach in to unlock the door from outside. This design also prevents a thief from quickly exiting the door with a large, expensive item, like a flat-screen television, after entering the house through a small window.
  • Safe for occupants inside your home: A double-cylinder deadbolt enhances security and ensures the safety of individuals inside. This is especially valuable for young children or elderly family members with dementia. A person may not quickly exit undetected because it requires a key to unlock. 

Cons:

  • Safety concerns: In emergencies like fires, evacuation may be delayed because a key is needed to unlock the door. This can pose safety risks, so some fire codes may restrict their use in certain cities. If you have a double-cylinder deadbolt, consider leaving an emergency key hidden in a nearby area that won’t be easy for a thief to find but where family members can quickly use it.
  • Inconvenience: Daily use can be less convenient than single-cylinder deadbolts because you always need a key to enter and exit from both sides. We recommend using an additional deadbolt called a Night Bolt on any door with a double-cylinder deadbolt. 

The Pros and cons of a single cylinder deadbolt

Pros:

  • Convenience: Single-cylinder deadbolts are convenient to use because they can be locked and unlocked from the inside using a simple thumb turn or knob, eliminating the need for a key for a quick exit.
  • Simplicity: Single-cylinder deadbolts are straightforward to operate, making them user-friendly for people of all ages, including children and the elderly.

Cons:

  • Security vulnerability: A single-cylinder deadbolt may provide less security as compared to other lock types. For example, a potential intruder could try breaking a nearby window and then reach inside to manipulate the thumb turn and unlock the door.
