Choosing the best lock for your home

It may seem like an easy item to check off your to-do list, but choosing a lock to protect your home is a very important decision. There are many different types of door locks, but not all locks are created equally. In fact many can be compromised with just a little skill, study each of these features to ensure your lock is safe and secure:

  §  The bolt. Make sure the bolt extends at least one inch into the door jamb; this will help keep the door secure if it is kicked or hit violently. The bolt should also have a hardened, free-spinning steel pin, which makes the bolt more saw-proof. Locks with a six-pin keying system are also more difficult to pick than a five-pin system.

  §  The strike plate. This is a metal piece that is mounted inside of the door frame that holds the bolt. It would be ideal if it was made of heavy-gauge steel or brass and should come with screws that are at least three inches long to securely fit it to the door frame.

  §  The plug. Both the plug (the part that the key turns) and the cylinder (surrounds the plug) should be make of forged solid brass. Avoid any locks that use brass-plated zinc, which is softer and easier to destroy.

  §  The housing. Choose a lock with housing that attaches to the door, rather than sitting on the surface of it. This will prevent a burglar from simply sheering off the deadbolt.

  §  The door. Sliding doors are a favourite target for burglars since they often have a lock on just the handles that can be easily defeated. Add an auxiliary lock with a steel bolt that attaches to the door frame, rather than another sliding panel, to prevent horizontal and vertical movement.

It’s also important to remember that home door locks should just be one component of your security system, you should still invest in a security system for your home or business.
