as I haven't a wireless keyboard, there are fewer troubles and I have spares just in case.
Two ways of looking at using a Windows PC keyboard if you have no other (Apple) options:
Microsoft provides this: keyboard mapping article how to to use Windows keyboard with OS X.
And there is this backward to look into what keys on Apple K/b does in Windows functions:
A wireless keyboard can add to troubleshooting, especially if it isn't working.
Have you tried to restart with the Shift key held, to start in Safe Mode? You can usually
better troubleshoot the causes of Kernal Panic among other issues, in Safe boot mode.
The use of OS X Recovery's version of Disk Utility can help repair the system, you may
not need to re-install the OS X (but you could) and a Time Machine backup can help in
the restoration of the previous system if you need to start over.

• Apple OS X and Time Machine Tips:
Apple Wired Keyboard Usb
The NVRAM reset (Cmd + Opt + P + R) is best to hold all four buttons immediate at First
chime, while I continue to hold them down through Three chimes; then let all them go..
As part of a troubleshooting mission, some aspects of System Management Controller:
'reset' may be of help to alleviate symptoms or causes. It will not repair OS X damages
if some other product has broken the system. The instructions suggest limits in use.
If you have used mackeeper, cleanmymac, or other tuneup/clean product, they may have
damaged the OS X since they're bad and almost intentionally muck around & damage the
Mac operating system most often. There is a way to remove each different type. Also avoid
unnecessary antivirus scanning software that can slow the computer way down.
Hard to say what else to do, or what you have done so far in attempt to troubleshoot.

Hey there a_nialator,
It sounds like you are unable to use your keyboard, as it doesn't seem to respond to anything when you are logged into your account even after resetting the SMC, but other devices work to the same usb port. I would use the troubleshooting from the following article to help you get that resolved, named:
- Try a different port and cable
Connect your device to a different USB or FireWire port on your Mac. If you connected your device to a USB or FireWire hub or to a port on another USB or FireWire device that's connected to your Mac (known as daisy chaining), connect your device directly to a port on your computer. Some devices need to draw power from a USB or FireWire port to work; if you connect a device to a non-powered hub (one that isn't plugged in to a power source) or to a low-power port (such as the one on your USB keyboard), it may not work. If you have another known-good cable, try swapping the cable to see if that works. If it does, you should replace the problematic cable. - Check for device conflicts
Disconnect all USB or FireWire devices (including hubs and extension cables) except for your Apple keyboard and mouse. Then, connect the device in question directly to your computer. If your device works now, there may be a conflict between that device and one of your other USB or FireWire devices. If it doesn't work, go to tip 8. If you do have a conflict, you can determine which devices are affected. Connect your other devices to your Mac, one by one, making sure to test that each device works before making another connection. When you find the device that causes the issue, contact the manufacturer for assistance (check both manufacturers' websites for software updates and additional information). - Quit associated applications
If you're using a particular application that uses the device in question (for example, you're using Image Capture with a USB scanner), try quitting the application and then opening it again. - Try another user account or computer
If you have another Mac available, try connecting your device to that other computer to see if it works. If you don't have another computer available, log in to another user account on your Mac (or create a new user account and log in to it), and test the device again. If the device is working now, there may be a software conflict between the device and something in your original user account. - Check System Profiler for hardware Issues
Open System Profiler (from the Apple menu, choose About This Mac, then click More Info) and then click either USB or FireWire. If you don't see your device listed in the pane, the issue could be with the device itself or your computer's USB or FireWire port. To rule out the port, plug the device into another USB or FireWire port on your Mac and then check System Profiler again (press Command-R to refresh the window). Also try resetting the FireWire bus. If you see your device listed in the pane but it doesn't work, you may want to contact the device's manufacturer for assistance.
Thank you for using Apple Support Communities.
Cheers,
