Electronic Keypad Lock (120V ON/OFF)?
I’m looking for an electronic lock w/ keypad. I’m looking for something to open/close and electronic circuit (like to turn on/off a light bulb). I’ve searched all over the internet, only finding electronic DOOR locks (I don’t want to use these). I was hoping to find one that has 12 keys (0-9, #, ΣΎ), an LED/LCD display (to show keys hit, open/close, or anything else), and 3 LED’s (they would be to indicate ELECTRICITY FLOWING, CORRECT, INCORRECT). Anyone know where I could find something like this? Thanks!

You can’t and won’t. 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.
