I have had this foldable wireless keyboard for a while now. it works a charm except that every so often, the bluetooth pairing fails. I have checked that my batteries are good and that no key is stuck. I press the button with a little bluetooth sign for a couple of seconds, the bluetooth orange LED flashes, my phone find the keyboard and starts pairing but the code that I should enter on the keyboard never appears on my phone. at the end the phone gives up and says 'could not pair up with bluetooth because of an incorrect PIN or Passkey'. I think the problem comes from the fact that I am not getting the code that I used to get.
