Keyboard Remapping Issues

Hi! I’m currently running Windows XP on my laptop, and my Escape key has recently broke. As I cannot afford to send my computer away for the next few days, I was wondering if it was possible to temporarily map my ScrollLock key (or some other similarly useless key) to the escape function instead. I tried several programs, but none of them seemed to work out for simple remapping. I’m willing to edit the registry if needed, but I’d want fairly exact instructions. Can anyone help me out here?
