Installing an extra deadbolt locks on your entrance doors will definitely make your home safer and add to its protection.
Deadbolt locks are hard to break into and by having more than one deadbolyt lock installed on your door will make it almost impossible to break into .
How exactly do deadbolts work?
These locks contain a solid metal cylinder which is called bolt and that bolt goes into the door frame through a strike plate.
When turning the key inside of a deadbolt lock the bolt moves vertically from the door into a slot in the frame making unauthorized entry impossible without the correct key.
The American National Standards Institute (ANSI in short), set up a grading system for deadbolts and it became a standard measure to evaluate the level of security and durability of these locks.
In the ANSI grading system there are 3 level of security grades:
Grade 1: The highest level of security available intended for commercial doors use as these deadbolts stand the most strict testing including the highest number of lock and unlock cycles, door strikes and weight tests.
Grade 2: Offers a very good level of security and durability for residential and light commercial applications.
Grade 3: This is the lowest security grade and it is not recommended for external doors.
Deadbolt locks can upgrade your home security significantly, in contrast to spring bolt locks like doorknobs which can be easily compromised even with a credit card, deadbolt locks provide high level of protection.
Deadbolts are more resistance against forced entry attempts like kicking or shoulder slamming and for optimal home security we recommend to use a high quality and properly installed deadbolt with other so extra security measures like sturdy doors and a home alarm system as no lock can guarantee 100% protection against break ins.
