Found a metal bar on my driveway. Any idea what it could be?

There are several scenarios where a water meter key becomes essential. During a plumbing emergency, such as a burst pipe, quickly shutting off the water can prevent extensive water damage. Homeowners performing DIY plumbing repairs may need to turn off the water supply to work safely. Utility workers use water meter keys for routine maintenance and to restore service after repairs. In drought-prone areas, water meter keys might be used to monitor and control water usage effectively.
