The term security door can refer to the various actions used to strengthen the door against the breach of the door, seize Ram and lock, and prevent crimes such as robbery and house invasion. Security doors are used in commercial and government buildings, as well as in residential neighborhoods.
Some reinforced doors serve as fire doors to prevent or inhibit the spread of fire.

Security tools
Alarm
Alarm - designed to warn of robberies.
Lock
- Smart keys can be used to restrict door access only to people with electronic key fob or Near field communications devices, such as smartphones. This device is popular with land owners, who can enable and disable digital access without physically sending key messages. Locks can log the time of entry, and can trigger an alarm if it is hit during an attempt.
- Deadbolts - many manufacturers make deadbolts resistant to collision failures, picking and locking collisions. However, most deadbolts are not very safe. Consumer Reports Magazine Testing shows that many manufacturers make broken deadbolts and if not fail when style is applied to the door.
Reinforcement
- Strike plate strikes may involve strengthening the attack plate and/or door frames, to prevent the attack plate from being hit by the frame.
- Door reinforcements - various products are created to prevent delamination and/or door separation. The sheet steel plate can be placed behind or under the latch and wrap around the edge of the door to prevent the breaking of the door around the latch. Heavy duty products that place plates on either side of the door tied with screws or bolts can be used to prevent delamination.
- The door chain - allows the door to open slightly to look out while still being locked.
- Secondary, internal keys - slip bolts, hooks and special hooks, inserted metal beams or metal bars.
- Hinge screws - longer or special screws that prevent the door from being pulled away after removing the hinge pins. Often the hinge pin itself is tightened, from inside when the door is open, to the hinge to prevent the hinge pin picking without opening the door first.
Other methods
- Thief CD or MP3 Marauder - The sound of home occupancy is recorded on CD. CDs are played when homeowners are away, to mimic home occupancy activities.
- Door viewers - small fish eye lenses that allow residents to look out without opening the door.
- Door windows - there are three common methods for adding security to windows on or next to the door: security bars and grates, security films (coatings applied to glass in windows to strengthen them), or damaged windows (plexiglas, lexan, and other glass substitutes).
- Visibility - Most police departments recommend bushes cleared from near the door to reduce the possibility of thieves being hidden from public view.

Residential security
Public dwelling doors
The following are the types of doors normally used in residential applications: solid wood doors, panel doors (hollow and solid core), metal-eyed wood doors and metal-wrapped doors. Usually, door frames are solid wood. Residential doors also often contain wood.
Security tests by Consumer Reports Magazine in the 1990s found that many residential doors failed or delaminated when applied to them. The solid wood door holds more strength than the very common wood-door wooden doors used in newer construction. Manufacturers of various doors, Premdor (now Masonite) once stated in one of the 1990s "Premdor Entry Systems" brochures that "Extraordinary test results, Steel-tipped doors outperform wooden doors with a ratio of 7 to 1. When you consider nearly two thirds of all illegal entry is done through the door... One blow of 100 lb [lbf] attack force breaks the wood-eyed stile and opens the door.To actually open the steel-edged door it takes 7 strikes of 100 lb [power] strike. " Most door manufacturers offer a number of different door types with varying levels of strength.
Consumer Reports Magazine also reported in its test results that door frames are often separated with fewer styles applied and lower quality deadbolts fail when applied to the door.
The Chula Vista House Decrease Project that studied more than 1,000 incidents found that "the methods found to have relatively low effectiveness include: sliding glass door supports, such as wooden pens, as opposed to sliding door ducts or pin locks; deadbolts mounted on the front door only; and outdoor lights on the dusk-to-dawn timer ".
Hacking tactics
The Chula Vista Abduction Abduction Project yielded the following findings: "From the interview of the victim, we learned that 87% of the burglaries happened when the intruder beat the locked door with tools such as a screwdriver or crowbar, a target thief" whose door has no deadbolt lock... not a thief trying to crack a double-pane window during a successful or tried theft process. "
