Deadbolts



Today at Locksmiths Melbourne, we're going to look at the common deadbolt, a locking mechanism distinct from a sprint-bolt lock because the deadbot cannot be moved to the open postion withour rotating the lock cylider. The deadbolt provides an added degree of security because it is more resistant to entry methods without the correct key.

There are two main types of deadbolts

  • Single cylinder
  • Double cylinde


The primary differnce is that the single cylinder deadbolt can only recieve a key from one side of the mechanism.
Where as a double cylinder can recieve a key from both sides of the mechanism.

There are a few other types of deadbolts, they are

  • Single Cylinder with removable thumbturn
  • Classroom Function (thumbturn only unlocks door)
  • Exit Only Function (no external cylinder)
  • Pushbutton Deadbolt (mechanical or electrical)


Deadlocks provide an added measure of security than the spring lock because, you must have a key to open the door, it takes a large amound of force to pry the sliding mechanism without the correct key, making forced entry much harder.

There are some safty issues associated with the deadbolt. If there was a fire and the deadbolt was locked, the inhabitants could not easily force open the lock without the key. Locksmiths Melbourne there for advises that a key is left within the lock at times of rest so that should the inhabitants require an emergancy exit, they are able to do so without risk.
