Many people often ask what the difference is between a deadlatch and a deadlock. In fact, this question has come up so many times we’ve taken the time to explain the difference between the two.
What Is a Deadlock?
This is a type of lock that can only be unlocked with a key. It consists of a keyhole on one side and on the other side of the lock is a knob that can be turned. When the lock is in deadlock mode, the knob will not turn. This provides increased security. Still, even though deadlock doors provide a great amount of security, it’s important to remember not to leave them in deadlock mode when you are in the home. This is because if there is an emergency like a fire, you may find yourself trapped in the home if you do not have your key with you.
What Is a Deadlatch?
Similar to deadlocks, a deadlatch ensures increased security because it has security latches for doors. With this feature, the lock has a latch that is automatically engaged when the door is closed, securing the door. This makes it convenient when you have to leave your house in a hurry–you know that the door is locked as soon as it closes.
There are three modes associated with deadlatches:
- Passage mode: when the latch is in the “open” position, the door can be opened and closed with ease.
- Safety mode: when the door is closed, the latch and handle allow the door to lock automatically. To unlock the door, a key will need to be used from the inside.
- Secure mode: this is deadlock mode. When the lock is in this mode, it will only open if a key is used form the outside or inside of the door.
While deadlocks and deadlatches have some features in common, it’s important to know the difference so that you can get the appropriate lock for your needs.
Deadlatch vs. Deadbolt
What is a deadlock for insurance purposes?
Deadlocks and deadlatches are so secure that many insurance companies require some form of deadlock on your front door when purchasing home insurance. This is to ensure extra security in case someone breaks into your house. Getting this might reduce your home insurance rates significantly.
An active deadlock on your front door can prevent thieves from being able to unlock the door and taking large pieces of furniture from your home. However, make sure you do not have an active deadlock when you are in the home.
One of the main complaints that come up with deadlocks and deadlatches is that they are cumbersome to deal with. This may have been a major concern in the past, but recent models of deadlatches and deadlocks come loaded with anti-deadlatch mechanisms. These mechanisms unlock the deadlock door from the outside and simultaneously releases the latch on the inside of the door. This is helpful in preventing the possibility of you being locked in your house once you’ve locked the door.
