Just to make sure that you know this:
When you push the function button, you must press the light button very soon or it will not unlock the keys (if they were locked).
When you reset using the paper clip method, you need to have the paper clip ready to insert as soon as you turn the scanner on. Press it in immediately after you turn the scanner on.
When you do the initialize method, you must press 0 and then 1 very quickly after you turn the scanner on. Be sure to not turn off the scanner until the initialization is complete.
It does not take very much hesitation during the steps to keep the desired result from happening.
