1. Check Vehicle’s Battery

- Estimated Cost: $0
- Time Needed: 5-10 minutes
Detailed Steps:
- Pop the hood and locate your vehicle’s battery.
- Use a voltmeter to measure the battery voltage. It should read around 12.5 volts for a healthy battery.
- If the voltage is low, either charge the battery using a car battery charger or jump-start the car.
Expert Tip: A low battery can cause a myriad of electrical issues, including false alarms. Regularly check your battery’s health, especially during extreme temperatures.
2. Check Key Fob Battery

- Close the key fob and test its functionality by locking and unlocking the car a few times.
Expert Tip: Always keep a spare key fob battery in your glove compartment. You never know when you’ll need it.
3. Use Physical Key

- Outcome: The alarm stopped going off.
- Personal Experience: I resorted to using the physical key, and it actually worked.
- Estimated Cost: $0
- Time Needed: 5-10 minutes
