I dropped my car key in salt water at the beach

When a car key falls into salt water, the damage can be immediate or gradual. Salt accelerates corrosion of internal components, especially in smart keys with electronic circuitry. Although the key may seem to work at first, it commonly fails hours or days later. This type of damage affects the signal, battery, and communication with the vehicle.

• Salt damages electronic circuits
• It may gradually stop working
• It affects the key fob signal
• It may prevent the vehicle from starting
• Requires professional evaluation

Common damages from exposure to salt water

Exposure to salt water causes more aggressive damage than fresh water. This is due to salt's ability to accelerate chemical processes that deteriorate the faucet's internal components.

Internal corrosion

Salt causes rapid oxidation of metal contacts and internal circuits. This can lead to total loss of functionality if not addressed promptly.

Signal failures

The signal between the key and the vehicle may become unstable or be lost completely, affecting both unlocking and starting the engine.
