Most apartment break-ins don't involve lock picking or high-tech tools. Someone kicks the door hard enough to split the jamb, or lifts a sliding patio door off its track. For a property manager, each one is more than a police report. It means an emergency work order, a frightened resident, a possible lease break, and a story that spreads through the community faster than any marketing.
This playbook focuses on the part of apartment security you control directly: the doors. Cameras, gates and patrols all help, but they record or deter. They don't physically stop a door from opening. Reinforced doors do.
Why apartment communities get targeted
Multifamily properties have a few built-in risks that single-family homes don't:
- Many entry points in one place. Unit doors, patio sliders, ground-floor windows, breezeways and garages give a burglar dozens of options in a single walk.
- Turnover creates anonymity. In a busy community, residents don't know everyone, so a stranger in a breezeway doesn't stand out.
- Shared responsibility leaves gaps. Residents assume management handles security, and management assumes residents lock up. Damaged frames and broken slider locks can sit unrepaired between those assumptions.
- Builder-grade hardware. Most unit doors rely on a wood jamb and a strike plate held by short screws. That's fine for keeping a door closed and weak against a determined kick.
What one break-in really costs
Run this with your own numbers. Start with what it costs you to turn a unit: lost rent while it sits vacant, make-ready, marketing and leasing time. Then ask how many residents a single break-in might push to leave, in that unit and next door. Add the repair bill, and remember that a jamb that's been kicked once is weaker than before unless it's reinforced. For most portfolios, even one avoided move-out pays for a lot of door hardware.
Compare that with the cost of prevention. A Door Armor MINI PLUS set is $75 per door in our multifamily 12-pack ($900 for 12 MINI PLUS kits).
The door-first playbook
1. Audit before you buy
Start with data you already have: - Pull 12 months of work orders tagged "door", "jamb", "strike" or "lock" and map them by building and unit. - Walk the property and note doors with split or patched jambs, and sliders that don't lock or lift out easily. - Check door thickness and clearance. Door Armor exterior kits fit doors up to 1-3/4" thick. If you can fit two quarters between the door and frame when it's closed, the MINI Door Shields will fit. If not, use PRO Door Shields.

2. Reinforce the frame, the lock area, and against prying
The Door Armor MINI PLUS is our most widely used multifamily kit. Each set includes: - a 46-inch Jamb Shield that reinforces the lock side of the frame, where kick-ins split the wood; - 2 MINI Door Shields that wrap the door around the deadbolt and knob; - a Pry Shield that stops the door from being pried open once a kick fails; - all screws, including long 3-1/2" screws that anchor the Jamb Shield deep into the frame.
It's made in the USA from 18-gauge galvannealed steel, and your maintenance team can install it with a drill and no door replacement. Every kit is backed by our lifetime kick-in guarantee, good for as long as the purchaser owns the property: $500 on Door Armor MAX kits and $300 on Door Armor MINI kits. The MINI PLUS is a MINI kit, so it carries the $300 guarantee. The guarantee covers kick-ins (blunt force from a body part), not battering rams or prying tools.
3. Fix sliding patio doors at the same time
Factory sliding door locks wear out. Many have an operational life of about five years, and a slider that doesn't latch, or that can be lifted off its track, is an open invitation.
Armor Latch is a dual-locking sliding door deadbolt that stops the door from being lifted out or pried out of its track, which a broomstick in the track can't do. It can replace a non-functional factory lock, installs in about 10 minutes, and most doors need no drilling. The Armor Latch 10-pack is $32 per lock ($320 for 10).
4. Repair kicked-in jambs in one trip
When a door has already been kicked in, don't just glue and patch the splintered jamb. That repair fails on the next kick. You have two options: - FIX-A-JAMB Exterior: a 40-inch steel sleeve that gives a clean repair in about 15 minutes. It's a maintenance favorite, but it's a repair product, not a security upgrade. - Door Armor MINI PLUS: covers the damage and reinforces the door. For a unit that's been hit once, this is the better choice.
Carry both on the maintenance cart, and put one or the other on the door, so a broken-door call is still a single visit.
5. Build door security into make-ready
The cheapest time to reinforce a door is when the unit is empty. Add a line to your make-ready checklist: - Inspect the jamb and strike area for cracks or old patches. - Install or check Door Armor on the entry door. - Test the slider lock, and install Armor Latch if it doesn't latch firmly. - Re-key or change locks per your policy.
Within one lease cycle, every turned unit is reinforced and the cost is spread across normal turnover.
6. Layer the rest of your security
Doors stop entry, and the other layers improve visibility and deterrence: - Lighting: keep breezeways, parking and patio areas well lit, and fix outages quickly. - Landscaping: trim shrubs near ground-floor windows and patios so no one can hide. - Access control: maintain gates and building entry doors, and discourage propping. - Cameras: useful for evidence, but they record a crime rather than stop it.
7. Tell residents what you've done
Security is an amenity. Mention reinforced doors and slider locks in tours and renewal conversations, and give residents simple habits: - lock the deadbolt and slider every time, even for a short trip; - don't prop building doors or share gate codes; - report broken locks, damaged frames and suspicious activity right away.
What property managers report
"We were having 5 kick-ins a week. After installing Door Armor™, we haven't had a single issue in 6 months." – Juan, Houston Maintenance Manager (source)
"Since installing Door Armor™, we've had ZERO break-ins. It's been a game-changer for our communities." – Karen, Fayetteville, NC (source)
Maintenance teams have put it to the test themselves. Here's the Mobile Housing Authority with kicks and a sledgehammer:
Start with one building
You don't have to reinforce the whole portfolio at once. Start with the units and buildings that show up most in your door work orders, measure the change in kick-in calls, and expand from there.
