My dad has one of those keypads in his store, and it's right next to the door.
It would be fail RP if the keypad is behind a couch, the wiring of the keypad would be kinda...messed up
People would start making no-collide props, to 10 different rooms, and make 2 keypad in each of the room, that would be kinda fail RP aswell.
But thanks for suggesting this! This might just be me being weird, as you know me XD.
