Why does my Masterlock Safe beep 5 times and show a yellow light?
- KKevin SmithJul 29, 2025
If your Masterlock Safe beeps 5 times and a yellow LED light appears after entering your code, it means you have entered an invalid code. Wait one minute before retrying your code. Alternatively, you can open the safe with the override key.
