Home Invasion Protection: Hardware That Resists a Kicked-In Door

When a burglar kicks a door, the physics favor the attacker. The strike plate — the small metal tab mortised into the door jamb that catches the deadbolt — is typically held by two half-inch screws driven into nothing more than the door stop trim. A single solid kick generates enough force to split that trim away from the structural jack stud behind it. The deadbolt itself may be perfectly intact; the hole it was supposed to anchor to simply no longer exists. This is why the very first upgrade any Sandy Springs homeowner should make has nothing to do with changing a lock in a door — it is reinforcing the frame the lock depends on.

The solution is a heavy-gauge steel strike plate — sometimes called a door reinforcement strike or a 4-screw strike — paired with 3-inch hardened wood screws that bypass the trim and bite into the framing stud. Products in this category (Schlage and Kwikset both offer reinforced strike kits) cost very little relative to the protection they add. For maximum resistance, a full door jamb reinforcement kit wraps a 16-gauge steel channel around the entire jamb, covering the strike zone, the hinge side, and the lock bore simultaneously. Our skilled technicians at Brookhaven Locksmith install these kits regularly and can assess whether your current frame is a liability worth addressing before you invest in a premium lock.

A mortise lock for main door applications is not a surface-mounted unit — it is machined into a deep rectangular pocket inside the door slab itself. This integration means the lock body is surrounded by door material on five sides, making pry attacks and kick attacks dramatically less effective than they are against a standard cylindrical deadbolt. A quality mortise lock for main door use combines a deadbolt, a latch, and often an anti-drill and anti-saw hardened steel insert into a single unified assembly. Brands like Schlage offer commercial-grade mortise sets that meet ANSI Grade 1 standards, the highest residential and light-commercial rating available.

Installing a mortise lock is a job that demands precision routing and careful measurement — an improper pocket cut weakens the door rather than strengthening it. This is exactly the kind of work where calling an experienced locksmith pays for itself. Our team carries the tools and the know-how to retrofit a mortise lock into most solid-core wood and fiberglass doors without compromising the slab. If you are also curious about a rim lock for main door applications — surface-mounted deadbolts common on older homes and apartments — we can evaluate whether a rim lock or a full mortise conversion makes more sense for your door style and security goals. For the highest forced-entry resistance, however, a properly installed mortise lock paired with a reinforced strike plate is the combination we recommend most.

Not all deadbolts are equal, and the ANSI/BHMA grading system is the clearest guide available. Grade 1 locks (residential and commercial top tier) must withstand 10 kick or strike impacts of 75 foot-pounds each in testing — essentially repeated heel kicks. Grade 2 is adequate for many interior and secondary doors. Grade 3, which is what you find pre-installed on many builder-grade homes, is the weakest and the most common. If you look at the lock in your door knob right now and cannot find a grade label, assume it is Grade 2 or 3 and plan accordingly. A door knob lock alone — even a good one — should never be your sole exterior security layer, because the knob mechanism can be sheared off with channel-lock pliers. It must work alongside a separate Grade 1 deadbolt.

When evaluating deadbolts, look for a bolt throw of at least one inch (longer is harder to defeat with shims or leverage), a reinforced anti-drill steel insert around the cylinder, and anti-pick and anti-bump pin technology. Schlage's B60N and Kwikset's 980 are well-known Grade 1 options. Medeco and Mul-T-Lock cylinders add a higher-security key-control layer. If you want to change lock in door hardware yourself, these are the brands worth researching — but if you want the upgrade installed correctly, with the door properly aligned and the strike positioned for maximum bolt engagement, our team is a phone call away at (470) 288-3985.

The market for smart rim lock for main door and electronic deadbolt products has matured considerably. A well-chosen smart lock can add keypad entry, auto-lock timers, and remote monitoring — genuine security layers — but only if the underlying mechanical hardware meets the same standards described above. A smart deadbolt with a Grade 1 throw and anti-drill cylinder is meaningfully more secure than the builder-grade knob it replaces. A smart rim lock with a weak back plate, however, can be removed from the door surface with a screwdriver in under a minute regardless of how sophisticated the app is.

One practical note that comes up often: if you own a smart lock, you will eventually need to know how to change batteries in door lock units, because a dead battery is one of the most common reasons homeowners call us for an after-hours lockout. Most smart deadbolts — Schlage Encode, Kwikset Halo, and similar models — use four AA batteries accessible from the interior thumb-turn cover. A low-battery warning typically appears 30 to 60 days before full failure. To change batteries in door lock mechanisms of this type, remove the interior cover, swap all batteries at once with a fresh set of the same brand, and test the keypad before closing the door. Keeping a spare set of batteries on hand prevents the scenario entirely. Our team can also assess whether a mortise lock with an electronic cylinder — a growing option in both residential and commercial locksmith work — better fits your door and lifestyle than a surface-mounted smart rim lock.

Individual hardware upgrades help, but a front door is part of a system: the door slab, the frame, the hinges, the lock cylinder, and the strike plate all have to perform together. Hinge bolts (also called hinge guards) prevent the door from being lifted off its pins from the exterior on outswing doors. Door viewers and wide-angle peepholes reduce the need to open the door to unknown callers. A door security bar or floor anchor can provide a secondary reinforcement layer for sliding and in-swinging doors. Our experienced team performs security assessments that walk through all of these elements so you know exactly where your vulnerabilities are before an event rather than after.

For Sandy Springs homeowners, the reality is that most break-ins happen opportunistically and quickly — the goal of your hardware is to push the time-to-entry past the point where an intruder is willing to stay. A reinforced frame, a Grade 1 mortise lock or deadbolt, and a smart or traditional secondary lock working together typically achieve that.
