The term “deadbolt lock” refers to a lock that cannot be opened without the use of a key. In the majority of situations, deadbolts are affixed to doors that already have doorknobs. It is not activated by a spring and is frequently constructed of steel or brass, so it cannot be broken easily. Additionally, the absence of a spring boosts its durability.

This lock must first be manually fixed by entering the key before the door may be closed. Unlocking the door requires twisting the bolt with a key from either the interior or exterior of the structure, once the lock has been locked.

This form of lock will be left open when inside the property, as the key and knob set will function as the primary locking mechanism. These extra security features make the deadbolt lock one of the most trustworthy and extensively used locks, the electronic deadbolt lock being the most popular of them.

It is imperative to know the different types of deadbolt locks. A few of them are listed below.

  • Rim Deadbolt: A rim deadbolt lock is commonly an automated lock that is put on the door’s inner and will normally lock itself when the door is closed. Due to the simplicity with which this lock may be opened, it is not considered to be the most trustworthy or lasting solution.
  • Vertical Deadbolt: A vertical deadbolt, which is very similar to the lock stated above, also locks itself upon door closure. Alternatively, because it cannot be opened by brute force, it gives a better level of protection.
  • Keyless Deadbolt: This type of deadbolt lock is defined by its employment of a keypad rather than a traditional keyhole. Because a numerical passcode must be typed using the numeric keypad, this option is easier and more secure. A terrific example of the same would be an electronic keypad deadbolt.
  • Single Cylinder Deadbolt: This lock can be secured and unlocked from the interior with a turning mechanism, and from the exterior with a key mechanism. 
  • Double Cylinder Deadbolt: It is a type of deadbolt lock that employs a key mechanism to lock and unlock the door from both the inside and outside in order to give an added degree of security.

Door handle locks consist of a handle on the outside side and either a keyed opening or twist knob on the inside side. For added protection, this style of lock has a deadbolt rather than a spring bolt.
