The Security Ladder

The security ladder is an illustration of the levels of security that different types of residential security products can afford the user. We will use the rungs of the ladder, with rung 1 being the lowest level, and rung 5 being the highest level.

We will make a few assumptions about the entry we are protecting.

  • We have a solid core door 1 and 3/4 inch thick, the door frame is the typical residential pre-made door frame in good condition.

  • Rung 1  Might be a grade 2 or a grade 3 entry knob or lever, with or without a grade 3 deadbolt lock and no reinforcement of the strike. (an entry door with this hardware array is typical and will meet building codes in most jurisdictions) A door with this level of hardware is highly susceptible to kick-ins, hammer, wrenching or other brute force attacks, a little better than an unlocked door. These locks could be opened by picking or key bumping, however these are not typical methods employed by the typical home burglar.

  • Rung 2  Might be a grade 1 or grade 2 entry knob or lever, with a grade 1 or grade 2 deadbolt lock and a reinforced strike. as well as a fully reinforced door jamb both lock and hinge sides. See our article on Reinforcing Door and Frame Security. A door with this protection would be much more secure. Will be much less susceptible to kick-ins or pry-bar attacks. These locks could be opened by picking or key bumping, however these are not typical methods employed by the typical home burglar.

  • Rung 3  Might have a locking knob or lever lock, with a grade 1 UL 437 listed deadbolt lock, and a fully reinforced door jamb both lock and hinge sides. The UL 437 specifications require all solid metal construction, higher resistance to brute force, wrenching etc. higher resistance to picking or key bumping. Most UL 437 listed locks also feature some form of controlling who can get duplicate keys made. This would be considered a very secure entry!

  • Rung 4   Might a have grade 1 electronic keyless deadbolt lock, and a fully reinforced door jamb both lock and hinge sides. The electronic keyless lock raises the security level by eliminating the need to carry or use a key. No keys for kids to lose. Some provide for remote control via a smart phone, this is handy to let service people in. Deleting or adding users is easy to do. This would be considered a very secure entry!

  •  Rung 5   Might have grade 1 biometric lock, which requires a fingerprint, or some other personal identification attribute to operate. Locks in this class are highly secure and can be programmed for multiple users. The following video features the top 8 fingerprint locks
