Doors selected to guard a home should be constructed of metal, fiberglass (rated to be used as an outside door), or solid wood. Never place a hollow core door at an entrance point into a home.
If a glass panel door is in place, those on the inside can see out but whoever is on the outside can also see in. A decorative door does not have to contain glass; a solid door with a 180 degree peephole is effective and still can look just as nice.
For locks, a bolt lock with a one-inch throw and a matching key-in-knob lock should be sufficient. This is a standard set up on most doors. However, some homeowners choose to upgrade to an anti-pick and bump resistant locks, but it can include additional cost.
Rarely does law enforcement see a lock that has been picked or bumped. Most burglars simply kick in the door. In that scenario, the lock does not fail; the door frame does. Upon close inspection of the door frame, a metal plate with holes punched through it matching the size of the bolt lock should be visible. This plate is called a latch plate. Standard latch plates have two screws that secure it to the door frame. Remove those screws and check their length. Most will be around 3/8 of an inch. All a burglar would need to do is push the bolt lock and latch plate through the thin piece of wood molding. It is recommended to replace the 3/8 inch screws with 3-inch screws. In most cases, this will give the screw enough length to attach to a 2X4 used in the home’s frame. This makes the door tougher to kick in.
There is always more that can be done to increase door security. Buying a $10 security latch plate at a local hardware store could help make a door more secure. These latch plates are generally seven to eight inches long and allow for more reinforcement by increasing from two securing screws to six.

A second line of defense for doors is a home security system. If a glass panel door is present on the home, make sure to have glass-break sensors installed.
