Unfortunately my MBP has a serious issue with it's keyboard. Some keys such as the 0 and I no longer work. I was able to use a external USB keyboard to get around this problem. I don't think the Trackpad is having problems but since I have a mouse I use that. The problem is sometimes some keys are sticking so I can be in the middle of a Word document and my a key will start repeating that I'm not typing so the external Keyboard doesn't help in that case.
Since my MBP is over a year old it's not under warranty. I went to the Apple Store today and they can replace the keyboard for $150 plus labor in addition to it. With the new MBP's just around the corner I want to wait and upgrade to that so honestly, I just want life support now for my MBP until then. Is there any way I can disable the built in keyboard and just use the external USB keyboard for now? Is there some type of setting in the preferences or even a program I can use? I would imagine I can open it up and maybe pull a plug but I want to avoid this and don't what else may stop working.

If you're out of warranty, you might as well open it up. Maybe you'll fix the problem by checking the internal keyboard connector.

Closed lid mode might also disable the internal keyboard, but I'm not sure. And you'd need an external monitor.

Is there a keyboard kext in System/Library/Extensions that'll disable the internal keyboard if removed?

correct me if i'm wrong (at work and dont have my mbp with me) but in your keyboard and mouse preference tab in system preference, there's a check box to disable the trackpad when an external mouse is being used.

as for your keyboard, you could always turn on your num lock and that should disable a majority of your keyboard, i don't think theres a way to turn off the internal keyboard.
