Industry Security Standards
According to ANSI standards (ANSI Code 156.2, Series 4000), the following scale is used to grade locks. Each grade specifies minimum acceptable requirements for operation, key torque cycles, pull strength, impact resistance and finish.
Grade 1: Kwikset products meeting Grade 1 status. 
980/985 Deadbolt, which also passed the most stringent lock-picking tests, the UL 437 lock picking test, and the Japanese picking test.
In February 2010, the Kwikset
Smartkey Deadbolt was awarded the Consumer’s Digest Best Buy award for being the only affordable deadbolt lock that is bump-proof and easily rekeyed.
Industry security standards ensure the quality and durability of locks within defined benchmarks of operation and security. The two most highly recognized and widely accepted organizations for assessing the quality of locks are the
American National Standards Institute (ANSI) and the
Underwriters Laboratories (UL). 
ANSI/ BHMA (Builders Hardware Manufacturers Association) Grading System is accredited by the America National Standards Institute (ANSI), a private non-profit organization that administers and coordinates the voluntary standardization to develop and maintain performance standards for builder's hardware. ANSI/BHMA standards set forth different product grades for door hardware products. These product grades are defined by progressive levels of performance benchmarks in each applicable standard. The purpose of each is to help identify the quality and durability of locksets through a series of operational and security tests.
UL Standards and the Underwriters Laboratories is an independent product safety certification organization. UL 437 is a security rating that provides a barometer for the security of a keyed lock. Our Kwikset Signature Series 980 deadbolt, featuring SmartKey Re-Key Technology, met the UL 437 11.6.1 pick test, one of the toughest picking tests in the world. During the test, picking tools are used to manipulate the components of the lock device, which requires a high level of skill and practice.
