How often should I replace batteries in my SentrySafe?

You should replace the batteries in your SentrySafe at least once a year, or whenever you notice signs of low battery performance. Most electronic locks will give you a warning beep to indicate low battery, but being proactive can prevent lockouts. If your safe is used frequently or if you live in an area where temperature fluctuations are common, consider changing the batteries every 6 months. A real-world scenario includes a user who frequently accesses their safe for important documents but has never replaced the batteries, leading to a frustrating situation when the lock fails. Pro tip: Set a reminder on your phone or calendar to check the batteries regularly. Keep in mind that if your safe has been installed in a high-usage area, it may require more frequent battery changes than typical recommendations suggest.
