It's an easy step, yet some people still don't bother securing all the entrances to their homes. Many burglars walk right in the front door because the door is unlocked, the lock is easy to pick or remove, or the door itself is flimsy. Solid doors equipped with deadbolt locks and wide-angle peepholes instead of glass panels offer the surest protection. Sliding glass doors should be equipped with locking metal rods in the sliding channel. Be sure all accessible windows have locks, and if you live in a high-crime neighborhood, consider putting grates or steel shutters on all basement and first-floor windows.
