My Acer Aspire 5830TG-6614 keyboard locks. I've sent it in for fixing (among other problems) and it still locks.
When I try to open MS Word, Word tells me that my "Ctrl" key is pressed down even if I'm no where near it.
My guess is that my "ctrl" key is being overly sensitive when I type. But I still don't understand why it locks. I can't type and completely avoid being near the Ctrl key.
