Deadbolt door locks must be good because they are the types of locks looked for by insurance companies when they assess the security systems of a house for setting homeowners insurance rates. Keyless Deadbolt Locks So if you are looking for keyless door locks, choose those that are deadbolt. A deadbolt has a locking mechanism that cannot be moved unless the lock cylinder is rotated. This is in contrast to the spring-bolt mechanism which can be moved with application of force to the bolt. A deadbolt then is more resistant to forced entry. According to insurers, they prefer a Grade 1 rating for deadbolts, as rated by the American National Standards Institute. Based on a crime survey, most burglars enter through unlocked windows or doors, lock picking and lock bumping and they choose houses that have no deadbolts or secure locking systems. The deadbolt locking mechanism has been incorporated in keyless door locks, so now there are combination door keyless deadbolts, digital keyless deadbolts, and other types of electronic keyless deadbolts such as those with fingerprint and remote control options.
