If you are like many homeowners today, you may need a flat door lock system to help secure the doors of your home. You may already have a reliable lock, such as a deadbolt lock that is designed to provide maximum security. However, there are times when you may need to replace it, or add another key to the lock.


When you are shopping for a new flat entry door lock, it is important to understand how it works and its different parts. It is also helpful to gain an understanding of the security system that secures your house, since many modern locks use similar components. This type of lock system provides the mechanism for locking doors, which usually include a cylinder, a tumbler, and a key holder. The locking mechanism also includes a chain, which secures the door to the frame.


The most common type of lock in flat door lock system is the double cylinder lock. It consists of two cylinders, with the inner one having a shorter length than the outer one. A key is inserted into both cylinders, by turning them in a clockwise direction. This requires knowledge of how to operate a standard key or access code. Some of these types of door lock systems also offer keyless entry features, which make opening the door without a key much simpler.


The tumbler part of the lock system is what actually does the work to secure the door. Two cylindrical sections of tumblers are placed above the flat door, with each housing a half of an inch in length. This tumbler, when turned, cranks around a large drum, creating a torque that locks the door in place. A key may be inserted into the tumbler housing just before it is turned, though you may have to manually turn the tumblers in order to get them locked.


A keyless entry type of door lock can provide security for your home, business, car, or other valuable items. This system works exactly the same way as a standard deadbolt lock. Simply place any type of key you choose inside the lock and turn it in a clockwise direction to lock the door. If you do not have one of these locks, do not worry. There are many other types of locks that may be suitable for your purposes.
