If your wireless keyboard is still connected to your iPad, or if another wireless keyboard has paired with your iPad, you may find that your software keyboard does not show up when expected. Tapping the eject key on the wireless keyboard should solve the issue. If not, try these steps. If it does not appear, and ejecting your wireless keyboard does not allow the software keyboard to appear, try unpairing the device by navigating to Settings > General > Bluetooth > Forget this Device. You might also try powering down the wireless keyboard that is causing the interference. If neither of these solutions work, try disabling Bluetooth by navigating to Setting > General > Network > Bluetooth.
