What You Need to Know about Key Restriction


February 14, 2018



Are you worried about spare keys to your new apartment or office building getting into the wrong hands? Controlling access to your property can be challenging when there are multiple copies of your keys floating around; fortunately, a key restriction system can largely prevent unauthorized duplication of your keys, providing you with an added layer of protection. We’ll tell you everything you need to know about the practice.


What Is Key Restriction?

Unlike fobs and swipe cards, key restriction uses a traditional lock and key system (but with a slight twist). In general, the key maker uses laser cutting or coding machines to produce a key that matches the client’s specifications. They then create a key system with a specially designed lock that accepts only the keys cut for it, and install that lock in your home or business.


What Are the Benefits?

With restricted keys, you have complete control over who gets a copy of your key. Since the key is cut with lasers according to a specific pattern, it can’t be reproduced by another locksmith. Just as importantly, its specialized locking mechanisms make it pick-resistant, thwarting more creative thieves in the process. At Lockbusters, the Multi-Lock MT5+ is one of our most popular high-security lock and laser-cut key systems.

While you may spend slightly more on restricted keys than on their unrestricted counterparts, they’re a much more cost-effective solution. With only several keys that can’t be duplicated in circulation, you won’t need to worry about replacing your locks down the road, and you can control access to your home or business at all hours of the day.


A Key for Every Situation

Most renters, homeowners, and business owners can benefit from key restriction, but there are some scenarios in which it’s an essential asset. The following people are prime candidates for a key restriction system:

  • Business owners who want to add an extra level of security for their employees
  • Building owners who are trying to crack down on unauthorized Airbnb users
  • Renters who need to provide a key to management
  • Homeowners or renters who need to supply a key to a cleaning service or dog walker
