Three Reasons You Really Need A Deadbolt
If you are putting in a new side or back door (non-sliding), you know you need to add a lock. But many times these doors come with a space for only a doorknob lock, and no deadbolt. If the doors you've chosen for your home are like this, drill a hole in each for a deadbolt, and more holes for things like keyless deadbolts for extra security. While doorknob locks might seem to work just fine, they are not as secure as you need them to be.
