Place this clip at the moment of the key press in a dialing sequence, before the reaction that follows it. Follow a correct entry with a bell ding sound effect, or switch to a classic error sound button when the code fails and the scene resets.

This clip is the short DTMF tone for the # key, a clean dual-frequency beep lasting just over a second. It feels instantly familiar and oddly satisfying, like pressing a real phone button and hearing the system respond. It comes from standard telephone keypad dialing, where each key produces its own paired tone.
