@artur I just had this exact same issue, but managed to resolve it. If a key stays down after you clip it back in, it means you didn't clip it in properly, and the top of the scissor mechanism isn't clipped into the key, so it doesn't get pushed up. Remove the key again, and look at the little clips on the underside of it. You'll see the ones at top of the key need you to slide the key upwards towards the top of the keyboard to clip it in, wheras the ones at the bottom just requrie you to push down on the key to clip them in. So, position the key towards the bottom of it's "gap", then push down on the top part of the key, and then push the top part of the key up towards the top of the keyboard to get the top clips clipped in. Then just push down on the bottom of the key to clip it in.
