Most commercial applications require either grade 1 or grade 2 locking hardware. Grade 1 not only meets commercial building requirements, it also provides the best security available against vandalism and heavy usage. Grade 2 meets light commercial requirements and exceeds residential building requirements.
Grade 2 – Higher Residential Security Designed to offer excellent security and durability. Used mostly for residential applications and some light commercial applications. Grade 3 – Basic Residential Security The lowest grade provided by ANSI, and the minimal acceptable quality for residential door locks.
Typically used in commercial high traffic areas or door openings that will get a lot of abuse. Grade 2 is a medium grade and capable of operating through 400,000 cycles while withstanding 450 lbs of force per inch for lever locks. A good choice for light commercial areas. Grade 3 is the lowest grade.
The Grade 2 lock must pass a 400,000-cycle test. Twice as much as the residential. The Grade 1 lock must pass a 1 million cycle test. The difference between the Grade 2, which is a light-duty commercial lock and Grade 1, which is a heavy-duty commercial lock is significant.
The best grade of deadbolt lock is Grade 1. The grades are assigned by the American National Standards Institute (ANSI). This non-profit group was developed by the Builder's Hardware Manufacturers (BHMA) to set standards for a variety of industries.
ANSI Grade 2 door locks are great for home security. While they're not the most secure locks, they're better than a standard door lock but not quite as powerful as Grade 1 locks. Therefore, they're not appropriate for commercial buildings.

CR's take: The Medeco Maxum 11TR503-19 is the strongest deadbolt across all of our lock categories. It's top-notch for drilling, withstands kick-ins very well, and is designed in a way that makes it quite difficult to pick.
A lock's security is denoted by its American National Standards Institute (ANSI) grade, with Grade 1 the most secure and Grade 3 the least. A builder-quality tubular lock will likely be a Grade 3, a good-quality handleset a Grade 2.
Schlage and Kwikset are two of the most popular lock manufacturers on the market. Both brands make excellent locks that homeowners can easily install, but Schlage locks tend to offer higher security and reliability and are trusted by big businesses.
Seek out saw resistance. Another thing to look for when choosing a deadbolt lock is a saw-resistant bolt. These bolts make it much more difficult for a potential burglar to break in by sawing through your lock. It's an excellent deterrent, and it's important to make sure your locks have this feature.
Generally, single-cylinder deadbolts are less secure than double-cylinder options. They could potentially allow easier access to the home from intruders in the know. Furthermore, they're easy for small children to use, which means they could get outside without anyone being aware.

Each key has a complex rounded shape, this coupled with the magnetic element makes it an extremely hard lock to pick. The only way to gain access to the door would be for the key to be cloned, and in that case, a master locksmith would need to get their hands on the original key.
Basic Cylinder Locks
Deadbolts use a solid piece of metal to secure the door, while standard cylinder locks use a spring to help make it easier to lock the door. Unfortunately, the spring does not provide much security and it can easily be forced. Deadbolts, however, are still vulnerable to lock picking.
Deadbolt door locks are the most secure type of key lock and are commonly used on exterior house doors.
Single cylinder deadbolts are quite common in residential homes. Such locks use a key slot on one side with a thumb-turn mechanism on the other side; the key slot generally faces the outside of a door. This system also allows you to unlock and lock single cylinder deadbolts using a thumb turn from the inside.
Because Schlage locks are made of stronger materials, are superior in their mechanism, and provide far greater security than Kwikset locks, it should be mentioned that they are more expensive compared to Kwikset.
