A deadbolt is a type of lock that provides extra security for doors. Unlike a standard spring bolt lock, which can be easily opened with a credit card or similar tool, a deadbolt requires a key or a thumb turn to unlock. This makes it much harder for intruders to gain access to your home. Deadbolts come in various styles, including single-cylinder and double-cylinder, each offering different levels of security. Installing a deadbolt on your door is a simple yet effective way to enhance your home’s safety. Many homeowners choose to pair a deadbolt with a doorknob lock for added protection. When selecting a deadbolt, look for one that meets the ANSI grading standards, ensuring it can withstand forced entry attempts.
