Entering one character enters 5

Hello,

On my keyboard this morning pressing one key acts like I've pressed multiple. For example:

Pressing a gets me a'y7g

Also, Backspace is working like Enter

My laptop is hooked up through a docking station. Using the keyboard physically on the laptop is fine. It's just the external keyboard I have through the docking station.

I've rebooted and removed the keyboard from the hardware profile and reinstalled. Help?
