Nobody wants what you want. The best you will be able to find is a low voltage key pad with some kind of programmable features that you will have to interface to a relay that switches the high voltage. In fact, you are most likely to have to get a display, a keypad, a power supply, and a microprocessor, like those from Parallax to get what you want. Almost all those keypads that you see in buildings are connected to a central computer that provides monitoring and display messages - some have a battery and local processor so the door can still be unlocked and monitoring records kept even when the central machine is down.
