Security is a serious business. We consider every single thing we own as valuable and cannot bear the thought of losing them. This is true especially when it comes to our homes. Crimes like burglaries and break-ins are dangerous partly because they can happen when we least expect it. Keeping our doors locked is the best way to protect our homes should such an event ever happen, which is why deadbolts are a valuable item to have for your front door. There are three different varieties for the deadbolt: single cylinder, double cylinder and lockable thumb turn; all with their own strengths and weaknesses.
-The single cylinder deadbolt is usually found in most American homes. This type opens and closes the lock by using a key cylinder on the outside, as well as a thumb turn on the inside. It is a very simple locking mechanism, which is also its greatest weakness. If someone from the outside can somehow gain access inside, either through a nearby window or even a small peephole, they can use a few tools to easily open the door using the thumb turn.
-The double cylinder deadbolt is somewhat similar to the single cylinder type. However, it has a key cylinder on the inside and the outside of the door, essentially covering its weakness. However, this makes it incapable of being opened from the inside unless you have the key. This can be a problem in case of an emergency, though it can be rectified by simply leaving the key inside an easily accessible place.
-The lockable thumb turn is in a way, a mixture of both single and double cylinder locks. It has a thumb turn on the inside that functions just like a single cylinder lock, but it can be locked using a key. When used in your home, you can simply leave the thumb turn in an unlocked position and anyone is free to leave the house at any time. Meanwhile, if you were to leave the house for a long period of time, you can simply lock the thumb turn to prevent access.
If you need a deadbolt to secure your house, consider which of the three types you would prefer for your home. Most locksmith companies have ample models to choose from.
