Cost-effective security locks for Newcastle businesses


Ensure your commercial property has the best security with affordable security locks and a restricted master key system from The Lock Doctor. Established for more than 20 years, we have plenty of experience providing Newcastle businesses affordable cutting and key system designs.

Master key systems are ideal for medium to large businesses. They are custom designed to suit your needs and the keys are protected by patent law, so only The Lock Doctor can cut or duplicate them. It also ensures only the registered business owner or authorised staff members can have the keys duplicated, significantly reducing the chance of illegal copies being made.

There are a number of advantages to having a restricted key system, including:
  • Can be retrofitted to most existing locks
  • Keys are stamped & colour coded
  • Master keys for business owners & senior personnel
  • Restricted keys will only be able to access certain rooms or areas
  • Pick-resistant key cylinders
  • Patent is protected by law—preventing unauthorised duplication.

Deadlocks are another affordable domestic and commercial security solution. The Lock Doctor provides Newcastle properties with a complete range of deadlock sales and installations—at very competitive prices.

Many insurance companies recommend getting deadlocks installed in residential homes, as they provide superior security and deter thieves better than Yale locks. Take care when using them in commercial properties however, as fire escapes and emergency exits need to be easily accessible.

There are different styles available to suit your preference, including carbine, double cylinder and digital. Not sure what is best for your property? Our mobile locksmiths will come to your property and showcase some of our best products to help you out.
