What is a deadbolt


Today many people use deadbolt locks for their front doors. You might be curious why these locks are that popular. They are one of the best ways to enhance your home security. Deadbolts are really hard to pick and almost impossible to open with the help of a credit card or knife. These locks are made of solid materials, so they are resistant to various attacks.

There are two types of deadbolt locks – single-cylinder and double-cylinder ones. The first type is quite common. It has a keyhole on the outside and a thumb turn on the inside. It’s extremely convenient, as, in case of an emergency, you won’t have to search for a key. The double-cylinder one requires a key on both sides. It is considered to be the most secure option.

Sure Lock & Key knows everything about deadbolts and we want to share our knowledge with you.

What is the difference between deadbolt locks and regular locks


We have already discussed what a deadbolt lock is. Now let’s discuss its main advantages and disadvantages and how different it is from other locks. Let’s compare deadbolt locks and locks with latches and decide which type of lock is the best for the front door.
So, a door latch mechanism consists of a cylinder, a latch and a handle or knob. These locks are usually operated with a key from the outside and from the inside. Also, they can be opened by turning the knob. The latch part is connected to the handle or knob, so when you press or turn them, the latch gets released. These locks are really convenient and affordable.
Deadbolt locks are stronger and more solid than latch locks. They are usually composed of brass, zinc, bronze, or steel. So, unlike other locks, deadbolts are way more resistant to bumping, drilling and other attacks. They are way harder to pick than regular locks. If you own the double-cylinder one, it’s almost impossible to unlock it without the original key.

However, their high-security level might become their biggest disadvantage as well. In case of an emergency, like a fire, it might be quite hard to open the door and get out of the building.

Are deadbolt locks illegal


One of the questions we receive regularly is – are deadbolt locks illegal? You might think, why is this question common? Well, in general, deadbolt locks, especially double-cylinder ones, might be quite hard to unlock in case of an emergency like a fire. So, if a fire breaks out, looking for a key in a situation like that might be complicated and can cause a lot of stress.
However, there’s no official law in the United States that bans deadbolt lock installation. Some states or cities might have separate laws that prohibit the usage of double-cylinder deadbolts because of fire safety. Also, some buildings might restrict the usage of deadbolt locks as well.
However, if you’re thinking about a deadbolt installation and you have some concerns regarding fire safety, you might choose a single-cylinder deadbolt lock. It offers a high level of protection and can be easily opened from the inside.
