Securing Your Home for Hurricane Season: Lock and Hardware Tips
Hurricane prep covers windows, roofs, and generators — but door hardware and locks need attention too. Here's what to check before the season.
· 4 min read · Residential
Hurricane preparedness in Miami receives extensive coverage — impact windows, storm shutters, roof straps, generator fuel. Door hardware and lock security are less discussed but matter significantly: a door that fails in high winds doesn't just admit water, it creates a pressure differential that can remove a roof.
Why Lock Hardware Matters in Hurricanes
Door failures in hurricanes are primarily caused by: 1. Hinge failure under lateral load 2. Door panel failure (hollow-core doors) 3. Strike plate failure when the deadbolt is engaged but the frame fails 4. Door frame separation from the wall structure
High-quality lock hardware addresses items 3 and 4. A heavy-duty strike plate with long screws reaching the wall stud distributes the force that wind pressure applies to the door — this same force that a burglary kick test simulates.
Pre-Season Lock and Door Checklist
Complete this before June 1:
All exterior doors: - [ ] Deadbolt engages smoothly and fully - [ ] Strike plate screws are tight and 3 inches long (reaching wall stud) - [ ] Door is solid-core or steel — hollow-core exterior doors fail in high winds - [ ] Hinges are tight and screws are 3 inches long (reaching wall stud) - [ ] Door frame shows no water damage, rot, or separation
Before changing entry hardware, review impact door lock replacement requirements for your installed assembly.
Sliding glass doors: - [ ] Anti-lift pins or screws in upper track - [ ] Floor bar or lock in track - [ ] Sliding door rollers rolling smoothly (misaligned rollers stress the frame in wind)
Garage doors: - [ ] Hurricane-rated panel or horizontal bracing kit installed - [ ] Track and hardware shows no rust or looseness - [ ] Auto-close feature tested
Before deployment, include hurricane shutters and exit planning in the household review.
Locks in High-Wind Conditions
During a hurricane, lock your doors — but don't deadbolt all doors if you're inside. You need to be able to exit quickly if conditions change. Lock single-cylinder deadbolts normally; double-cylinder (key-required on both sides) requires you to have a key accessible.
Post-Storm Lock Maintenance
After a significant storm: 1. Flush all exterior lock cylinders with fresh water to remove salt water deposits 2. Apply a dry lubricant after flushing and drying 3. Test every lock for proper operation 4. Inspect door frame seams for gaps or separation 5. Check that all strike plates are still secure
Salt water infiltration into lock mechanisms causes rapid corrosion — address it within 24 hours of storm passage if possible.
If Your Locks Were Damaged
Storm-damaged locks should be replaced, not repaired. Internal corrosion from salt water infiltration compromises the cylinder even if the lock appears to function normally. Caraballo Locksmith provides post-storm emergency service and lock replacement across Miami-Dade.
Backup entry before a storm
Include a backup entry check by reviewing what happens to a smart lock in a power outage.
Lock inspection after a storm
After the property is safe to enter, review what to check if your door locks got wet in a storm.
