One of my family members spilled water on their 2013 MBA. I have the stick and actually got an enclosure for it but the...

I had this issue after re-assembly of front screen on an iPhone 5S. The symptom is light vertical bars that are obvious when screen is bright. In some cases, there may be horizontal bars creating a plaid effect. The screen also does not respond to touch input, making it impossible to shut down, apart from holding sleep and home button. (If the home cable is connected) I was worried at first that I had damaged the ribbons or pins on the pins on the three connectors. However, I found that I just needed to carefully but firmly press down the connection points until they were solid. I believe the top most connector is the digitizer, which is the easiest one to come lightly unseated while the screen is detached. I had the effect happen twice during the rear-facing lens cleaning run I was doing and was able to fix it both times.

I spent a bunch more time on this and was able to restore the key. It was not as good as before, but it did get back into place and it is now usable again.

One major issue with this is that the metal pins used to hold the metal bracket ends can bend or warp fairly easily. I think that a bent pin may have been what caused the stickiness on my space key in the first place.

Here's my guide: How to reattach a Spacebar Key to the Magic Keyboard

@jcwacky I could not understand your suggestions here. Like many others I've been unable to reattach the Spacebar key to the Magic Keyboard. Unlike other previous keyboards, this spacebar uses a design that makes it very difficult to reattach.

The main problem is as described, you reattach and it stays stuck down. From what I can tell, there is an orientation where small clips connect to the butterfly mechanism. Those go toward the bottom I think.

However, no number of other attempts make the key attach properly. I can not see any way to fix this. There are no youtube videos showing how to reattach the spacebar on the magic keyboard. Closest thing I found was someone saying it was nearly impossible and their key works worse now.

I'm super bummed I tried to clean this.
