Wireless keyboard won't turn on after changing battery

This is what happened:

I got a message yesterday telling me that the battery for my wireless keyboard was low and I should replace them. This morning, before I switched on my Mac, I put in new battery for the wireless keyboard. Then I switched on my Mac. And I got a message on the screen saying that There's no keyboard connected and couldn't find any keyboards. I thought that maybe I need to turn on the keyboard to make it work. So I pressed the power button and noticed that the green light doesn't even come up..

What's going on? Is my wireless keyboard already dead??

Any advice would be appreciate it. Thanks.

My wireless keyboard wouldn't turn on after I changed batteries. I tried the foil ball and other recommendations. Nothing worked. I thought something had failed or disconnected inside. I flipped it over to look for access to the back and noticed a faint graphic on the exterior of the battery tube.

I had put the batteries in 6 times and didn't pay attention to they way they came out. I reversed them and we're back in business. Green light is on.

I know my way around a spludger, I've changed hard drives, fans & memory in multiple MacBooks and missed the most obvious solution.

If you've given up on your wireless keyboard, give this a try.

Making sure batteries were in +end first (flat side out) and putting in a pea-size lump of aluminum foil worked for me.

Make sure you haven't turned off the keyboard like I did . Press the button (round circle) on the right side of the battery compartment.

Posting on a very old post is not useful. It is highly doubtful that anyone will read it.

This is a great solution. Hadn't been able to turn keyboard on for about 8 months. Did the paperclip thing and BINGO! Thanks

Thank you so much...I did what you suggested and it works, a thousand thank yous!

Same problem. Use screw driver to 'scratch' (clean) the contact. Also check the battery contacts. After a few attempts, it works.

Worked fine! Thanks.

I had the same problem. I didn't realize that on the right side of the keyboard, directly opposite the battery compartment, is a power switch.

What an awesomely simple solution. Hats off to you friend, brilliant! Had me thinking the keyboard had expired cos this has happened in the past and I changed the keyboard. Thank you so much.

Make sure batteries are in correctly, directions are on the bottom of keyboard. Also, simple but I forgot the "on-off" button on the other side from batteries. Simple but I missed it at first.

You asked a question of the original poster that is eight years old. Obviously he is not going to respond. Drop the "hope this helps" trolling, please
