A question that many locksmiths get asked is “what is the difference between deadlatch and a deadlock?” All of them have their unique functionalities and security mechanisms, each providing you the best security depending on what your needs are.
If you want to learn more about what the differences between a deadlatch, a deadbolt, and a deadlock are, then please read below and we explain what the differences are.
What Is A Deadlock?
A deadlock is a type of lock that can only be unlocked using a key when it is in deadlock mode. It consists of a keyhole on one side and a turnable knob on the other side for heightened security.
Deadlocks increase your protection; however, they are not recommended to be set in deadlock mode while you are at home especially in events of emergencies. This is because scrambling to find your key may endanger you if, say, a fire were to break out inside your home.
If you are going to keep the deadlock mode on while you are at home, make sure you know where to find your keys, or that they are nearby the lock, in case of any unexpected emergencies.
What Is A Deadbolt?
A deadbolt is quite similar to the deadlock in terms of functionality. It is a type of lock that requires a key to lock and unlock. They are also installed on doors that have a doorknob set already installed.
Deadbolts usually have a single metal locking bolt that protrudes from the door and into the wall, which makes it nearly impossible for an intruder to force the door open.
Deadbolts are fashioned to add and increase security to doors, doubling the lock security especially when no one is at home. People often use the deadbolt only at nighttime or if they are not present on the property.
Both deadlocks and deadbolts are commonly used in residential and commercial properties, either on their own or accompanied by a regular latching lock.
What Is A Deadlatch?
A deadlatch is a type of lock that can automatically lock itself without needing a key or a knob to move the blot in place. Essentially, it contains its own security latch which can immediately lock itself as soon as you close your door.
You will commonly find deadlatches on front doors that do not have a handle. However, deadlatches are considered convenient especially if you are the type of person to always rush leaving the house.
Generally, there are three modes that deadlatches have such as the following:
- Passage Mode, wherein the latch is open and the door can be easily opened and closed.
- Safety Mode, wherein the lock and handle will automatically lock once the door is closed. A key must be used to unlock the door from the inside.
- Secure Mode, wherein the lock can only be opened from the outside or the inside of the door.
Modern deadlatches today already have an anti-deadlock device installed in them. These devices are designed to unlock the interior deadlatch system once you come home and unlock the door.
So, what differentiates these three types of locks? Well, deadlocks and deadbolts are the same in that they both need a key to lock. However, while a deadlock can only be unlocked in deadlock mode with a key, deadbolts can be locked and unlocked with a key and have a metal lock that extends from the door into the wall.
When at home, it is suggested to turn off the deadlock mode of deadlocks or to have your key nearby, to prevent being locked in your house in case of emergency and the inability to find your keys.
Meanwhile, deadlatches are the types of locks that can automatically lock themselves once you close the door. They come in three modes depending on whether or not the latch is activated. Some deadlatches also come with anti-deadlock devices that unlock the deadlatch on the other side of the door once it is opened.
Choosing the right lock depends on what safety level you are looking for and what property you are securing. However, you can never have enough safety, so it would be wise to consult with a locksmith on what lock options are suitable for you.
