Short answer: The Peninsula never hands your hardware a brutal winter, so it is easy to assume your locks and gates just take care of themselves. They do not. Our wet season and our long dry summer each stress locks in a different way, and matching a little maintenance to the calendar is what keeps a stiff cylinder from becoming a lockout on a rainy night.

From roughly late fall through early spring, the rain does two things. Wooden and some fiberglass doors absorb moisture and swell, which pushes the deadbolt out of alignment with its strike; suddenly a lock that worked all summer needs a shove to throw. At the same time, water and morning fog work into exposed cylinders on front doors, side gates, and detached garages, corroding springs and washing out old lubricant. Before the first real storms, add a dry PTFE lubricant to every exterior keyway and check that each deadbolt still throws fully with the door closed. If a door has swelled enough that the bolt no longer seats, do not force it night after night; that is how you snap a bolt or wear out a cylinder. Adjusting the strike plate is the fix.
Summer brings the opposite problem. Fine dust and pollen settle into keyways all season, and it is abrasive; every turn of the key grinds a little of it against the pins. Landscaping makes it worse in two ways worth watching. Sprinkler heads that arc onto a gate latch or a low door lock leave mineral deposits that gum up the works, and irrigation-fed corrosion is one of the most common reasons a side-yard gate lock seizes. Mid-summer, blow or wipe dust out of exterior keyways before re-lubricating, and reaim any sprinkler that is hitting a lock or a metal gate. On gates specifically, the padlock or latch hardware lives fully in the weather, so it wears years faster than a sheltered front door and deserves a closer look.
Electronic and smart deadbolts have become common on Peninsula homes, and they fail in a season-agnostic but very predictable way: the batteries die. Most give you weeks of low-battery warnings through the app or a beeping keypad, and most people tap 'dismiss' and forget. Cold snaps and long gaps between use both drain them faster than the packaging promises. Two habits prevent nearly every smart-lock lockout: swap the batteries on a fixed schedule, for example every spring, rather than waiting for the warning, and always keep a physical key that works the override cylinder, stored somewhere off the property. A dead smart lock with no backup key is one of the more frustrating and avoidable calls we get.
