Deadbolt locks are a great way to improve the security of your front door. These types of locks are an additional layer of protection against brute force and jimmy attacks. There are many different types of deadbolt locks on the market.

The number of options can be overwhelming if you’re looking to install a deadbolt lock on your front door. In this article, we’ll break down the types of deadbolt locks and the pros and cons of each.

What is a Deadbolt Lock?

A deadbolt lock is not like a regular lock. The bolt of a deadbolt lock is designed to be locked in place, which makes it difficult to be bypassed by a credit card or Jimmy tool. It won’t move unless triggered by the locking mechanism. Another notable difference is deadbolts often have a thumb-turn switch for the interior and a key for the exterior.

Types of Deadbolt Locks

1. Single-cylinder deadbolt Lock

Single-cylinder deadbolts are the most common and provide a decent level of security. A single-cylinder deadbolt has a thumb turn on the interior of the door and a key on the exterior. It offers a simple way for people to lock their doors from inside their homes. Just flip a switch to lock or unlock the door from within. The only way to unlock the deadbolt from the exterior is with the designated key.

2. Double-cylinder deadbolt Lock

A double-cylinder deadbolt has a key slot on both sides of the door; the interior and exterior. There are no thumb turns. These types of deadbolts are mostly used in offices and commercial properties. It’s not ideal to use double-cylinder deadbolts in residential properties because they make it harder for people to exit the building. Some double-cylinder deadbolts require separate keys for either side. It is crucial to keep in mind the ease of escape in case of an emergency. 

3. Keyless or Renter’s Deadbolt Lock

These deadbolts are designed to be operated through a thumb switch located on the interior side of the door. They do not require a key on either side. The primary purpose of a keyless deadbolt is to provide tenants with added security without the inconvenience of carrying keys. In certain locations, property owners are mandated by law to use these types of deadbolts on the front doors of rented units.

4. Electronic Deadbolt Lock

Electronic deadbolts have the same core function as regular deadbolts, except the locking mechanism is controlled by a key code. Most electronic deadbolts have a keypad on the exterior and a flip on the interior. The upsides to electronic deadbolts are you don’t need a key to unlock it and anyone who has the code can unlock it. The downside is a power outage can lock you out of your home.

What is the Best Deadbolt Lock for Your Front Door?

Choosing the right deadbolt lock boils down to your personal preferences. In our opinion, the best deadbolt locks for residential homes are single-cylinder or keyless. These provide an easy way for people inside the home to lock the deadbolt. Keyless or renter’s deadbolt locks are also convenient. Double-cylinder deadbolt locks are ideal for high-security locations. Electronic deadbolt locks are good for homes with multiple tenants or family members.
