3 Reasons to Invest in a Secondary Lock

Having a secondary lock is an important part of keeping your home and property safe. It can provide an extra layer of security against burglars, vandals, and other criminals. With the right type of secondary lock, you can rest assured that your home or business is protected from unwanted intruders. Here are three reasons why you need to invest in a secondary lock for your property:

  1. You don’t know who has your keys or passwords: Whether you are renting, or have been in a house for years. Keys and passwords get passed around to realtors, friends, family, ex’s, maintenance and more. Unless you just built your house and installed all of the locks yourself, it’s still a good practice to install something that only locks when you are inside. 
  2. Lock condition/installation: When you get into a new place, you have to just assume all doors and locks are functional, in many cases, the locks are misaligned, old, or damaged. Don’t rely on old hardware to protect yourself. Make sure to get something that works, is easy to operate, and will be reliable over time. 
  3. Lock Strength: Many don’t know that a kick, or good lockpick can bypass their lock in seconds. For your average deadbolt, they are only rated for 75lbs. worth of pressure, that’s easily overcome by force. The FlipLok is installed onto your doorframe, and reaches the studs of the homes framing. This greatly increases the strength and allows the lock to do its thing. Unlike Deadbolts who rely on a compromised door that you had to drill a hole into to install it. When you lock a door, you expect it to stay closed, get a FlipLok to ensure it does.
