Thank you very much.

This is wireless keyboard, I tried to turn it off, changed the new battery, but it's still not working. I found on google, someone said that maybe I turned on the mouse key, they show how to fix that but only if u are already logged in.

My problem is Ithat can't log in so I can't use the same trick.

If you put in new batteries, the keyboard needs to be paired before it will work. And you will need a wired keyboard to be able to log in and pair the wireless keyboard. Ask a neighbor to lend you his wired USB keyboard for a few minutes.

That has not been my experience with our Macbook Air with its Apple wireless keyboard. With that wireless keyboard, when the batteries are replaced, one just needs to push the power button once on the end of the keyboard to turn it back on and it immediately "remembers" the computer it was paired with. In fact my daughter ran down her keyboard batteries at college back in March and waited for me to replace the keyboard batteries when she came home in mid-May, so they were really dead, and it knew immediately the computer it had been paired with as soon as I pushed the power button. We have a wired keyboard around here also but never had to use it.


There may be something else going on here because he said that two keys do work on his keyboard but the others don't. I agree with the earlier suggestion to try a wired keyboard. If the wired keyboard works, then the problem is with the wireless keyboard.

Well, my last 2010 iMac needed a wired keyboard so I could pair the wireless after I replaced the batteries; I just got a new iMac and have not yet had to replace the batteries on it, so I don't know if there is a difference. If I wanted to avoid using a wired keyboard, I did not shut down or sleep the iMac (avoid having to enter password) and replace the batteries at around 10% or so. I missed it once and shut down the Mac; there was no way other than the wired keyboard to get past the password.


Not sure about the fact that two keys may be working; we'll see after he borrows a wired one.
