Managing the security to your home

Why use Dead locks on my doors?

Why does my Insurer want me to have Deadlocks?

It seems to be standard with all insurers that when covering the Burglary or theft risk, the minimum security they will accept are Deadlocks on all external doors. This certainly applies to Householders Insurance but with Business Insurance, they are prepared to look at other alternatives such as a “back to base” alarm, rollerdoors, grilles and Padlocks.

These days, depending on which State you live in, Insurers do clash with Fire Safety Departments who believe that may types of Dead Bolts or Dead Locks are dangerous. They cite concerns such as:

  • Do not keep them locked on the inside when the home is occupied – if there is a fire, you do not want to be delayed looking for a key
  • Do not keep the bolt out and locked to use to stop the door fully closing as many doors are Fire and Security Doors
  • Changing the locks can actually weaken Security and Fire Doors meaning a breach of regulations.
  • Twist type knobs can be too hot to touch to turn in the event of Fire.

On the other hand from the Insurers point of view, they of course want the locks to be used properly but they are very good at reducing or minimising break ins’ to property, particularly in these scenarios.

  • Burglars will try to enter through a door. If they can make a hole in the door or break a small window, they can reach around and un-latch the door.
  • Burglars may enter through a small window or opening, and before they do anything else will set up an escape route and the best way is through an open door. If it is key-locked on the inside, then it limits this potential substantially. It also limits what they can take forcing them back out the way they came.

You will never stop anyone who really wants to break into your home. All you can do is minimise or delay the time they have to do so. They will not want to spend much time in your property and it is much harder to run off with that 50 Inch LCD Television through a window than through a front door.

A decent Deadlock is only part of your security solution. There are other things you can do and you should check your local Fire Safety Regulations applicable so you do not incure breaches or fines.

In Queensland, this is an issue, but the only product I can see that both Insurers and Fire Safety advisors seem to agree on is the following type of lock. Speak to an experience and reputable Locksmith too as they should know the regulations too. But ask for the following Double Cylinder “Deadlatch” with a push down lever.
