What happens
- Moisture and salt attack plated finishes and internal springs.
- Keys get stiff and bolts stick.
Maintenance
- Rinse salt from hardware in spring.
- Use a dry lubricant made for locks.
- Avoid heavy oil, which traps dust.
Choosing hardware
- Look for corrosion-resistant finishes.
- Choose outdoor-rated electronic locks.
When to replace
A lock that is stiff after cleaning or shows deep corrosion.
Why lakefront hardware wears faster
Damp air, wind-driven spray and road salt speed up corrosion on latches, hinges and cylinders. Homes on the bluffs and near the lake often see rust on screws, stiff bolts and finishes that flake within a few seasons.
Maintenance that helps
Rinse exterior hardware with fresh water after salty weather, dry it and apply a light protective lubricant to moving parts. Check screws and replace any that show rust. Seal gaps around the door so moisture does not reach the lock body.
Choosing hardware for the coast
Look for stainless steel or solid brass with a durable finish, and avoid cheap plated zinc. Ask for a lock rated for exterior use. Replace a lock when the key catches, the bolt drags or the finish has broken through. See frozen locks and winter lockouts.
Signs it is time to replace
A key that catches, a deadbolt that needs a push to turn, a handle that has gone loose or hardware showing rust through the finish are all signs the lock is near the end of its life. On the bluffs, homes facing the lake can see this after fewer years than homes inland. Replacing before it fails avoids a lockout in bad weather and lets you choose the hardware calmly.
