Understanding Key Lock Boxes

Key lock boxes offer valuable advantages that make managing access and security easier. Here’s a quick rundown of their benefits:

  • Key lock boxes streamline turnover between guests or tenants, making check-ins and checkouts smoother.

I have been using an outdoor key safe myself for some time now. It helps me and my wife to manage our travels in a much better manner especially when kids have so many classes to attend to.

The Best Key Lock Box: Master Lock Key Lock Box (Personally Using)

Are Key Lock Boxes Safe? 

Largely key lock boxes are safe to use and trust your house security with. However, it is important to recognize that locks are designed to deter honest individuals, but it’s a reality that no lock is completely impervious to skilled manipulation. 

In our lockpicking community, it is a well known fact that a lock deters only the honest people. And folks with advanced lock picking skills can break into any lock. Therefore if you are wondering if your key safe can be picked or not, obviously it can.  And I will give you an example of it.

I have been using MasterLock 5400D as my preferred key lock box for some time now. I chose that after much deliberation and testing several products in the market but did I ever think that it can’t be picked? No. 

As is shown by The GOAT (LockpickingLawyer) himself in this video that it can be picked within minutes if not seconds. 

So does that mean that I made a wrong choice? Does that mean that I can’t trust it with my house keys?

The answer is again NO.

Lockpicking Lawyer is the most respected lock picking guy known around the world for his skills. He has put in hundreds of thousands of hours to hone his skills. So obviously what he can do in seconds (or minutes), others might not even be able to do that. 

Therefore in my humble opinion, no lock is safe if you have someone as skilled as LockPickingLawyer picking your lock. 🙂

Having said that, ensure that your key lock box ticks some boxes to make it harder to be picked than others. 

Some Tips To Enhance The Safety Of Key Lock Box

  • Strong Build Quality : When we talk about key lock boxes safety, it is not only the picking that we have to be concerned about. Breaking or hammering is another concern that we have to keep in mind. And for that, it is always advised that your key safe is built with durable material (such as stainless steel) which resist breakage. And this is true especially for shackles. 
  • Change Combination Frequently: If you are using a combination key safe, change the code frequently. Using the same code for a longer period of time increases the chances of theft. Needless to say that your code change should be done when no one is around.
  • Install Security Cameras: I would recommend installing security cameras around to keep an eye on any unwanted element. This will act as an additional deterrent to mischievous elements.
