Key switch next to front door

Anyone have any clue what this is for? My family and I just bought a house that has this by the front door and the previous owner doesn’t know what it is for (they just flipped it).

Pull the cover off and see what its wired to? Reminds me of an elevator lockoff key which obviously it isn't.

I thought of the same thing like a lift for elder or something but I’m there isn’t a multi steps by the front door.

Old school alarm?

Dunno for your house but In our high school the janitors used to open the garage door with what OP has, turn the key and garage door opener opens the garage door from

That’s a standard (albeit very odd in a home) key switch. It could really be controlling anything a standard switch would control (lights, switch, equipment, etc). You’re likely only going to figure it out by opening it up and determining where the wire goes. If you find the breaker and turn it off, change the switch to a standard switch and turn the breaker back on. Now you can turn it on and off and see what it is doing.

Thanks all for all your input! I guess I have to test it!

Can't be anything related to security as anyone with a fingernail could open it up and bypass the switch.

I'd pull the plate off, get a multimeter and test for voltage. Then find the breaker that services it.

It may be low-voltage like a doorbell, wired to a transformer somewhere in the basement. The wiring from that transformer would then tell you what it turns on and off.

My Aunt, to this day, has a standard doorbell button mounted outside her garage to open the garage door. Lives in the county but urban is very close.

Probably a garage door opener.

Agree. We have one like this but never got the key when we got the house. But tracing the wires inside the garage, you should see something lead to your garage door opener from this lock.

if someone's gone to the effort of installing a key switch it would be kind of disappointing if it can be simply "pulled off" without at least the use of some obscure security screwdriver.

The photo shows it is clearly 2 slotted screws just like any old faceplate.

And yet you must be disappointed after looking at the photo.

Oh, I didn't open the photo. If it's that easy it must be booby trapped ;)

This is like Willy Wonka...don't eat that blueberry candy kid.

Let's stick a finger in there and see what happens. LOL

Looking forward to the mystery key switch answer.
