Residential Deadbolt Lock

One of the most widely used types of residential door locks is the deadbolt. There are two types generally used for the home: the single-cylinder and double-cylinder. The single-cylinder has a knob that twist on the interior side with the keyhole on the opposite side. The double-cylinder has locks on both sides of the door and you will need a key to open it.

Why Use a Deadbolt Lock

This is a proven type of reinforced security that is routinely installed. Intruders have to put for a lot of effort into breaking into a home with this type of security feature. It’s simply easier for them to break-in where there is no deadbolt lock. However, if it is not properly installed, it will be useless. Another good reason to use this type of lock is because it is an affordable way to secure your property, typically under $250 per door for parts and installation. The reputation and reliability of it also makes homeowners more comfortable when they have them installed in their homes. This added sense of security is worth the cost.

Which One Will You Choose

Since the single-cylinder is easier to use, it is generally used most often. However, some homeowners prefer the more durable and somewhat more challenging option of the double-cylinder deadbolt. The single-cylinder will require that you have a key to open when you are opening from the outside. They will unlock from the inside by simply turning the knob. With the double-cylinder, you will need a key to open from either side. This is not always the best option when in the event of an emergency where you must quickly evacuate your home. In this case, you will need to have a key in close proximity to the door and know exactly where it is located.

Overall, having one properly installed is a better option than not having one installed, at all.
