Question Control key stuck but not physically (Lenovo T420)

[starkiller211]

i got a Lenovo T420 laptop which was working fine until today, for some reason it things that the control key is pressed down. Every time i press the backspace button it inputs { , space dosent work and many other keys. I tryed using a linux usb but the problem still presists. I've also tryed to switch the ctrl key and the fn key from the bios and still nothing.Any and all suggestions are welcome, Thanks for your time.

Try an external keyboard? Replacement keyboards for that model should be pretty cheap, try another keyboard.
