PC Power Button - need key to power on PC

[Chungus2332]

would this work?

 

My idea is to have to turn  the key to then push a button to start the PC

Yes an ignition switch is just a "switch", so your power button won't function until the key switch completes the circuit. 

 

You would basically just be using the key switch to break / connect  the power button wire.

so i would only be able to turn on my pc if the key is switched to on?

I use something like this.  For a few of my projects, that I've found at a local Napa. It was in a Napa branded package, but it looks very similar.

Not the way it is drawn. You would still need to hit the power button.  Do you want it to turn on with the key?

Technically yes but bypassing that by shorting the pins on the mobo is super easy

Then you can do that, but as mentioned, someone with physical access could still turn on the PC if they really wanted to, if they opened up the PC.  Just like someone with access to a car can steal it without keys if they really want to.

 

As mentioned your diagram will work, you just break one of the power button wires with the key switch. You can use your existing power switch in your PC if you want. 

 

They make kits for electronic code locks even if you wanted to get fancier, but that would make things a little more complicated.

There are PC locks you can find online that do what you want. Keep in mind that standard locks can be picked in less than 30 seconds. The best locks are very difficult for all but very skilled pickers like the Lock-Picking Lawyer, Deviant Ollam and their friends in YT.

 

My house key dropped off my ring yesterday and, using a paperclip and the weak ring straightened out, I was able to pick it by raking in less than 10 minutes, even though I'm not a lockpicker. With an actual rake, it would've been less than a minute because my lock sucks. 

 

As pointed out, access to the inside of your PC will allow anyone with knowledge of pin-jumping to start your machine. You can buy a case lock, too, but it's still pickable. Better off finding a device that prevents jumping inside the case, or maybe somethingsuch as a great Australian car invention that Scotty Kilmer showcased on his YT channel recently. Locks are better than nothing, though, so get a power button lock and a case lock at least.
