Key in Water Symbol Car: Smart Key Battery Being Low!
When your car dashboard displays a symbol that looks like a key inside a water droplet, it’s typically an indicator of the vehicle’s Smart Key battery being low.
This symbol is common in modern cars with push-button start systems and keyless entry. It advises you to replace the key fob’s battery soon.
Most modern vehicles are equipped with Smart Keys or key fobs that enable keyless entry and ignition systems.
As the battery in the key fob depletes, the car’s system detects the lower signal strength and triggers a warning light or icon on the dashboard to alert the driver.
The icon can vary slightly between manufacturers but often resembles a key enclosed in a water droplet or waves, signifying fluidity or the flow of electrical current.
Here’s what you typically need to do when you see this symbol:
If you see the key in water droplet symbol, promptly replacing the key fob battery will ensure the continued convenience of keyless operations and prevent potential lockouts.
Key Takeaway
Understanding the ‘Key in Water’ Symbol
How does the ‘Key in Water’ symbol in a car function and what does it indicate?
The ‘Key in Water’ symbol, typically found on a car’s dashboard, is a warning light that alerts the driver if the vehicle’s security system has been compromised due to potential water damage to the electronic key fob.
When this symbol illuminates, it indicates that the key fob has been submerged in water or is experiencing a malfunction due to moisture.
