Gun Safe - Full (10-digit) keypad

I love the idea of the Gun Safe. But why the keypad only has number 1-4? How do we enter a combinations that requires numbers 5-9 and 0? I wish you’d given us a regular number pad for combinations. I don’t want to come up and memorize another combination only consisting of 1s 2s 3s and 4s… And especially remember it in an emergency…

[Mod Edit]: Title modified to enhance search clarity.

Most small gun safes are like this. But it’s really a non issue because you can open it using your fingerprint or the key or via the app.
