Door lock level
The level of the door lock is a measure of the quality and safety of the lock. The grading system is used to determine the strength of different types of locks and then grade them according to their level of safety and life. Using the grading system used by ANSI (American National Standards Institute), level 1 locking is classified as the strongest and level 3 locking is classified as the lowest level. These locks are tested to determine how much force they can withstand, and they can also see their retention during certain periods of use. The level of door locks is important for the price of the door lock, as the cost of a Class 1 lock for commercial and residential properties is generally higher than for Class 2 and Class 3 locks.
In this case, there is a direct correlation between the price of the door lock and the security it must provide. The cost of cutting the door lock level can have a negative impact on your safety, unless you emphasize other measures around you, but even then you may still be at a disadvantage. Higher levels of door locks tend to cost more because they last longer and are more costly in the long run.
These numbers may sound similar, so I wouldn't be surprised if you think that the price of your door lock should be different. However, in terms of security, these numbers may also be separate from the world.
