How do I link my iPad with the keyboard.

Hi, Ilene,
If the keyboard does not work and you have had it for 3 to 4 years. I would recommend to replace it. I am not sure what kind of Ipad you have, but I do know that the best aftermarket keyboards for iPad are the Logitech ones. I have left you a link to their website and you can see the best option for your Ipad. There are some that the keyboard comes with a cover. Hope this helps.

It's fairly easy to set up usually. With the keyboard powered on there is usually a button that turns bluetooth on and a (usually) blue light will start flashing. At this point on the iPad you look in the bluetooth settings page and look for the keyboard to appear in the available devices. Tap the link to it and follow the instruction. The blue light should stop flashing and remain lit and the iPad BT settings will show that the keyboard is connected.

Watch this link I posted here. Maybe this could help you out. Maybe the bluetooth is not enabled in either your ipad or your keyboard.

Perhaps you look on this link to see you did everything right, like charging the battery, switching on and pairing. Don't forget to switch on bluetooth on your iPad. SHARKK Apple iPad Air Wireless Bluetooth Keyboard Case

Check that the keyboard's battery is working and it's on. Turn on Bluetooth on the iPad (Settings > Bluetooth). Press the keyboard Connect button. Choose the ZAGG Keyboard on the iPad, and type the code on the keyboard.
