First, check if the gate is receiving power and if the remote batteries are working. If the gate only hums without moving, the motor or gearbox may need repair. In South San Francisco’s damp climate, corrosion on sensor wires or limit switches is a common cause. We can diagnose the issue on-site—either repairing the existing motor or replacing worn components. For gate lock failures, we often find the locking mechanism has jammed due to salt air buildup. We clean and lubricate the latch, replace worn bolts, and adjust the alignment so the gate closes securely.

Manual gates rely purely on hinges, latches, and the strength of the frame. Common issues include sagging hinges, rusted locking bars, or a gate that drags on the ground. Repair involves tightening hardware, replacing hinge pins, or re-leveling posts. Automatic gates have additional components: motors, control boards, sensors, and wiring. Repair requires testing voltage, checking photo-eye alignment, and troubleshooting the logic board. For homeowners in South San Francisco who experience frequent gate lock failures, we recommend upgrading to heavy-duty latches for manual gates, or installing a weather-resistant lock for automatic systems.

The coastal fog and salt air cause metal components to corrode faster. Lock cylinders jam, bolts seize, and electronic strikes short out. We see this frequently in neighborhoods near the San Francisco Bay. To prevent failures, we install stainless steel or brass locks with sealed mechanisms. For automatic gates, we use weatherproof actuators and apply dielectric grease on electrical contacts. Regular maintenance—cleaning and lubricating moving parts every six months—greatly extends lock life. If you already have a broken lock, we can replace it with a corrosion-resistant model and adjust the gate alignment to reduce strain on the latch.
