Time to Upgrade Your Home Security?ĭoes your front door have an up-to-date deadlock? If not, you may not be adequately protecting your family and property contents.įitting deadbolts, deadlocks and deadlatches to your door helps keep out burglars from your home and office. Thankfully lock manufacturers have evolved their deadlocks, such as the popular Lockwood 001 Double Cylinder Deadlatch, to prevent users from locking themselves inside. For example, you can easily become locked in without any way of getting out. However, you must be careful when using Secure mode (if your lock has this function). Insurance companies love deadlocks, deadbolts and deadlatches because it is harder for burglars to break through these locks, gain access into your home and ultimately steal from you. Why Insurance Companies Insist on Deadlocking Devices The lock is in deadlocked mode which requires a key to both exit and enter. Secure Mode: In this mode the interior knob will not function without a key.

So, even though you need a key to enter from the exterior, you do not need a key to exit when in safety mode.

  • Safety Mode: The knob on the inside of the door can open and close the lock.
  • Passage Mode: The locking mechanism is permanently unlocked so the door can be freely opened and shut.
  • Here are the three modes of operation with double-cylinder deadlatches. This is great as you can leave your house by turning the internal knob to open the lock and then the latch will allow the door to close and lock as your exit.ĭeadlatches also come in single and double cylinder options to allow even more functionality. However, a deadlatch allows the function of locking without a key as you close the door.

    Traditional deadlocks and deadbolts need to be locked with a key that extended or retracts the locking mechanism. This is different from a traditional deadlock which includes a lock assembly and another piece of metallic hardware that secures the locking mechanism to the door frame.ĭeadbolts also come in single and double cylinder options.Ī deadlatch combines the advantages of a deadlock with that of a latch. This makes it next to impossible to open the door forcefully when the deadbolt is in the extended position. What is a Deadbolt?Ī deadbolt is a special type of deadlock with a bolt that extends into a hole in the wall or floor. The risk with this is you can lock yourself or someone else inside unintentionally, so be cautious when using this mode of operation. To exit deadlock mode you must insert the key in the internal or external keyhole and unlock the lock.īy using this deadlocked mode you can safeguard your house so that if an intruder breaks into your property through a window or another access point they will be unable to exit through a deadlocked door. When the lock is deadlocked, turning the internal knob will not unlock the deadlock. This allows more flexibility and security when compared to a single-cylinder deadlock.Įssentially double cylinder deadlocks introduce a deadlock mode. One keyhole on the exterior and one on the interior. With this variation, there are two cylinders and as such two keyholes. Of course, the exterior always requires a key to open and close the lock, and thus gain entry. The reason for the interior knob is so you can open the lock, and thus exit from inside the property. In this variation, the knob on the interior of the deadlock does not have a keyhole. This knob may or may not have a keyhole, which results in two different types of deadlocks. On the interior side of the door, the deadlock will have a knob. The rest of the lock is on the other side of the door (the interior), and these two parts connect through the door itself.

    As mentioned above, a deadlock has a keyhole exposed on the exterior of the door.
