When it comes to door locks, there are a variety of choices available on the market. But when it comes to protecting your home, the two main types of locks are single cylinder deadbolts and double cylinder deadbolts. Both locks serve the same purpose, to protect your home from unwanted visitors, but they do have some key differences. In this article, we'll discuss the pros and cons of each type of lock and help you decide which one is best for your home.
Single Cylinder Deadbolts
Single cylinder deadbolts are the most common type of lock used on residential homes. They are typically easier to install than double cylinder deadbolts, as they only require one hole to be drilled in the door. They also come with a keyed cylinder on the outside and a thumbturn on the inside. This means that the lock can be opened from the outside with a key and from the inside by simply turning the thumbturn.
Single cylinder deadbolts provide a good level of security, as the keyed cylinder on the outside is difficult to pick. However, they are not as secure as double cylinder deadbolts, as anyone can gain access to the lock from the inside simply by turning the thumbturn.
Double Cylinder Deadbolts
Double cylinder deadbolts require two holes to be drilled in the door and they come with a keyed cylinder on both the inside and the outside. This means that the lock can only be opened by a key from both sides, making it more secure than a single cylinder deadbolt. However, double cylinder deadbolts also present some drawbacks.
For one, double cylinder deadbolts can be difficult to install, as they require two holes to be drilled in the door. They also present a safety hazard in the event of a fire. If the key is left in the lock on the inside, then it can be very difficult to get out of the house in an emergency.
Pros and Cons of Single Cylinder Deadbolts
Pros: Single cylinder deadbolts are easier to install than double cylinder deadbolts and they provide a good level of security.
Cons: They are not as secure as double cylinder deadbolts and anyone can gain access to the lock from the inside simply by turning the thumbturn.
Pros and Cons of Double Cylinder Deadbolts
Pros: Double cylinder deadbolts provide a higher level of security than single cylinder deadbolts.

Which is Best for Your Home?
When it comes to choosing the best lock for your home, it really depends on your individual needs and preferences. Single cylinder deadbolts are easier to install and provide a good level of security, but they are not as secure as double cylinder deadbolts. Double cylinder deadbolts, on the other hand, provide a higher level of security, but they can be difficult to install and they present a safety hazard in the event of a fire. Ultimately, it is up to you to decide which type of lock is best for your home.
