Residential Master Key System Installation

One key for all your external doors

For residences that have many external doors, keeping track of all the different keys can be challenging or frustrating. A master key system is a perfect solution. With a master key system, you can have one key that works on all your locks. So the key that works on the front door, can also work on the back door as well as the side door and garage door.

As master locksmiths, we can take care of all your master key needs. We can review your home, recommend where to install the master key locks, install the locks and make all the keys. It’s a turnkey solution (no pun intended) where we handle everything from start to finish. In the end you’ll have peace of mind knowing your home is safely protected, while also bringing simplicity to your life.

Of course, such an investment is a big decision, but by considering a master key system at your home, you would certainly reduce the risk of becoming a victim of crime. Here are a few benefits you will have over individual key systems –

  • Having a master key system by Armor Security installed in your house allows you to carry one single key in your pocket each day and unlock a multitude of doors including the front door, back door, and garage door.
  • Time-Saving. You do not want to waste time looking for separate keys when you are in a hurry. With just one or two keys that come with our master key system, you can secure all the valuables and leave without any hassle.
  • It is crucial to have different levels of security, but not that makes the accessibility for the owner a nuisance. Hence, when you purchase a master key system from us, you get access into the home without compromising on the safety or juggling through with several keys.
  • A sturdy locking mechanism that comes with advanced technology doesn’t have to burn a hole in your pocket. You may find the initial charges of installation a little expensive, but once done you will be surprised at the long-term cost-effectiveness you get.
