Cheap locks can spoil the security of your home and office.

November 1st, 2017

As strong locks and quality keys are of great importance for the security of residential and commercial buildings it pays to avoid buying low price locks. Remember purchasing cheap locks helps to make entry to your premises easy for thieves and thugs.

A main door lock should be a minimum of four levers and the higher the lever count, the greater security of a lock. Keys should be of a type that is difficult to copy which will help to avoid unauthorized duplication. When you are buying a new lock you should choose one with keys with high security features.

Special care should be taken when you buy a house, or became a tenant because you will not know who has duplicate keys. For example copies may have been made by the servants of the previous occupants and the staff of building contractors. Moving can be an expensive exercise and if you are unable to buy new locks immediately you should rotate the locks from inner doors to the outer doors as a minimal precaution.

Always take great care of your keys and spares. Keys should be given only to trustworthy employees and it is worth having them sign for the keys to create accountability.

There is a trend to fit biometric (finger print) locks on important doors which give superior security compared with conventional locks. In recent years locks have became available for linking with your mobile phone by Bluetooth to provide a PIN code for access control.

If you do fit padlocks, buy high quality items and not the spring closing type which can be defeated in seconds by using a simple lock pick. It is worth protecting the padlocks fitted to entrance doors with a steel housing to prevent breakage by saws, or grinders. Deadlocks, or rim bolt locks are recommended for the main door of flats and houses because they cannot be pushed open.

While thinking about your choice of locks make sure your door is safe. In many cases break ins and robberies are made easy by weak doors and poor installation. This can enable thieves to remove the door and the frame so it is important to make sure your door is strong and the frame is heavily bolted to the wall

Although strong doors, quality locks and keys are important for the protection of your home, or office you should also have a modern fully automatic intruder alarm system. This protects your property and assets around the clock even if you are asleep, or absent.
