SOURCE: acer aspire 5100 keyboard does not type characters
There is a small ribbon cable that connects the keyboard to the motherboard inside. It is very likely that the ribbon cable has become loose enough to no longer make contact. If you send me the model of your computer, I could probably find you a diagram of pictures to guide you through taking the keyboard out of your laptop to re-seat the cable.
SOURCE: Bios Password Reset
The only idea I have is to find and disconnect the CMOS back-up battery after removing main battery and unplugging the AC adapter. That SHOULD clear the bios completely, wiping out the password, the date, and everything else.
I know this works on desktops, and most laptops, but no promises, and the cmos battery may not be easy to access.
You should probably leave the battery unhooked for at least 1-2 minutes to be sure it clears.
Hope this is some assistance!

Here is the link to your service manual, when you click on it and bring it up...it is a pdf file so you'll need adobe or another pdf reader, go to page 40, that is the directions for resetting and removing the BIOS/hard drive password. Good luck
