Short answer: Foster City's lagoons and bay breezes are part of the appeal, but the same salt-laden, humid air that drifts off the water quietly works its way into exterior door hardware. A little seasonal attention keeps a sticky lock from turning into a stuck one.

Why Waterfront Air Is Rough on Exterior Hardware
Salt and moisture are a lock's slow enemies. On homes that face the lagoons or sit closer to the bay, the fine mist carried by the breeze settles on knobs, deadbolts, and strike plates, where it feeds corrosion inside the mechanism you never see. Pin tumblers pick up grit, latch springs weaken, and the bolt itself can develop a gritty resistance that gets worse each season. Many original Foster City homes still run hardware from the community's earlier decades, and older finishes are especially prone to this kind of wear. The first sign is usually a key that needs a little jiggle or a deadbolt that no longer throws smoothly with one turn — small symptoms worth catching before the lock refuses to cooperate on a cold, wet morning.
A Simple Seasonal Maintenance Routine
Twice a year, give each exterior lock a few minutes. Wipe the visible hardware down to clear salt residue, then use a dry lubricant such as graphite or a PTFE-based product rather than an oil spray — oily lubricants can attract dust and grime over time and gum up the very pins they were meant to help. Work the key in and out a few times and turn the deadbolt fully several times to redistribute the lubricant. While you're there, check the weatherstripping around the door and the screws holding the strike plate; corroded or loose strike screws are a common, cheap fix that prevents bigger alignment problems. Keeping water from pooling against the threshold and making sure the door closes squarely also reduces the moisture that reaches the lock body.
When Maintenance Isn't Enough
If a lock keeps sticking after cleaning and lubrication, grinds when it turns, or the deadbolt won't fully extend, the internal parts may be corroded past the point maintenance can fix. That's the time to rekey or replace rather than fight it. For a home in this climate, it's worth asking a locksmith about solid-brass or marine-grade exterior hardware, which stands up to salt air far better than budget builder-grade sets. Replacement costs vary with the grade of hardware and how many doors you do at once — typically a modest range per door for standard residential lever or deadbolt sets, and more for heavy-duty or smart hardware — so it's reasonable to ask for a quote up front before any work begins.
