Single vs. Double-Cylinder Deadbolts: Which Is Better?

Discover the differences between single and double-cylinder deadbolts to understand the best option.


Choosing the right deadbolt can make all the difference to home security. If you’re considering a new lock for your entryway, you may have come across two options: single and double-cylinder deadbolts. How do you know which is better? Let’s explore the key differences to help you make the right choice for your home.

Single-Cylinder Deadbolts Offer Convenience

A single-cylinder deadbolt has a keyhole on the outside and a thumb-turn on the inside. This type of lock is popular for its ease of use, especially in emergencies when you need to exit and secure the property quickly. It’s also more affordable than a double-cylinder deadbolt, making it great for homeowners on a budget.

Unfortunately, there is a security risk. Experienced burglars can easily pick single-cylinder deadbolts with a bump key or other tools and gain entry to your property in a matter of seconds—no matter how sturdy your deadbolt may be.

Double-Cylinder Deadbolts Enhance Security

Double-cylinder deadbolts require a key to lock or unlock the door from both the inside and outside. This design provides an extra layer of security, making it more difficult for burglars to gain entry by unlocking the door. However, the need for a key to open the door from inside might be a concern during emergencies when you must exit swiftly. Also, double-cylinder deadbolts are generally more expensive than single-cylinder models.

Weighing Your Options: Safety vs. Convenience

When deciding between a single and double-cylinder deadbolt, consider the balance between your security and convenience needs. Single-cylinder deadbolts suit those who prioritize ease of use during emergencies. Keep in mind that these locks can be easily picked. Though more secure, double-cylinder deadbolts should be accompanied by safety plans to ensure quick exits during emergencies.

As you decide on the perfect deadbolts for your doors, find the balance between security and convenience. Whichever option you choose, upgrading to a high-quality Emtek lockset gives you a safe and elegant lock for your home. Browse our selection of locks today!
