What Happens If the Lock Battery Dies?

Summary

If your smart lock battery dies completely, digital access features — including app unlock and keypad PIN — may stop working because the lock needs power to operate. Physical keys and mechanical backups, where provided, work independently of lock power.
Battery death is different from a power outage. The lock's batteries power the smart features directly. When they run out, even a building with full power may have a non-responsive lock until the battery is replaced.

How battery alerts may appear

  • Some smart locks display a low-battery warning in the Grata app or send a push notification before the battery dies.
  • Some locks produce an audible tone or flashing light at the keypad when battery is low.
  • Not all locks have the same warning behavior — some may give little or no warning before stopping.
  • If you see a low-battery alert in the app or on the keypad, contact your building team promptly so they can arrange replacement.

What may happen when a lock battery is low

  • The keypad may respond slowly, require multiple attempts, or wake up inconsistently.
  • Digital Key or app unlock may work intermittently or stop connecting.
  • Some locks enter a low-power mode that still accepts access until the battery is fully exhausted.
  • Behavior varies by lock model and manufacturer.

If the lock stops responding

  • The keypad will not light up and will not accept PIN entry.
  • App and Bluetooth Digital Key will not connect.
  • A physical key or mechanical backup, if your building provides one, should still work.
  • Do not force the lock or repeatedly try PINs if the keypad is completely unresponsive.
  • Contact your building team immediately — a dead lock battery is a building maintenance issue, not an app issue.

Who handles battery replacement

  • Battery replacement is a building maintenance responsibility in most buildings.
  • Contact property management or your building's maintenance team to report an unresponsive or low-battery lock.
  • Do not attempt to replace lock batteries yourself unless your building has specifically instructed you to do so.
  • Emergency lockout situations should follow your building's emergency access process.
