A constant beeping sound from your keypad may occur due to:
Low battery
Internal reset after a battery change
Temporary keypad interference
If you are experiencing continuous beeping, try the following steps:
Use Duracell or Energizer 9V alkaline batteries (with at least 5 years before expiration).
Do not use rechargeable, lithium, or off-brand batteries — these can cause inconsistent power or keypad failure.
Disconnect the battery from the keypad.
Press each button twice (e.g., 11
, 22
, 33
…).
Let the keypad rest for 5–10 minutes.
Reinstall the battery.
Try opening the safe using your combination.
