How do I turn off Caps Lock?

The same way you turn it on.

Note: Caps lock WAS off when you typed the question.

Ok fireball it’s real easy turn off the cap lock button it’s that easy stop screaming at us.

I don't know where that is on an automobile.

Use the KUNG FU finger of death and hammer on it to get it to release.   It finally will or you need another keyboard.   I am on my third.  The letters disappear.

with a hammer , it will either fix it or f$ck it ..

You got it all wrong. You need to turn it ON, LIKE I JUST DID

Don't ask Steven H. He spilled his  pablum on his Caps Lock.

I. Personally, pop the C/L  button off every keyboard I get. With my ham hands, I too often hit C/L instead of Shift.

Apologies,. Steve.No solid caps lock, This time...

I think you know that judging by your mixture of lower and upper case question. Poor trolling. 

press the caps lock key on the left hand side of the keyboard.

The dealership service department can help you with that
