Anyone else having issues with keys simply not responding until hit multiple times?
My backspace key is driving me nuts 
I opened a GitHub issue a while ago but so far haven’’t had a reaction?
Usually the switch when this has happened to me. And usually the result of user error installing them.
Have you tried a different switch?

Thanks for chipping in David. Not sure what you mean with “switch” in this context?
The UHK is directly connected to my docking station, I don’’t use a keyboard/monitor switch. The keyboard keys are original and unchanged.
In fact nothing changed from a hardware perspective in a while.
I now experience more and more double clicks, means I hit backspace once and it deletes two chars. It’s also not only the backspace key, e.g. right now the “p” key acts up, every second/third time I get two chars for the price of one.
I did connect the UHK directly connected to my laptop to rule out docking station related issues, issue is still there.
The keyboard of the laptop works as expected, no issues at all, so I think I can rule out the OS/IO side of things.
The more I test the more I think this is related to the UHK driver. Maybe I need to consider to downgrade, or upgrade to a beta build if one is around that promises to fix this.
Edit: I just remembered, I did, for the first time, change some key bindings in the UHK-Agent. Nothing dramatic, just two keys changing. Could my issues have started back then, maybe, can’t really tell.
Just made another change but things stay broken.
@Tunney is referring to the switch in the key itself. Sounds to me that the most likely issue is a poor seating of the switch in it’s socket. You can try pulling the switch out of the socket, bending the legs of the switch ever so slightly and then re-seating the key. Your say in your Github story that you have a UHK80. Do not try pulling switches in a UHK60v1! Those are not hot-swappable.
It may also be worth removing any modules and thoroughly cleaning the contact points of the pogo pins as well as the pins themselves before reattaching them. Re-seating the bridge cable, if you use one, can’t hurt either.

Interesting, that seems to have fixed it?!
I tried it on the backspace and “p” keys and both seem to work reliably again right away. Thanks a lot guys for helping out fixing this big annoyance.
Really glad to find out that the fix is so easy. Looks like I need to have this little tooth puller tool sitting next to me for a bit longer and address the trouble makers one after another as they show themselves 
I used to fix connection issues like this with a bit of WD40, not sure if this is a good idea in this scenario?
No, do not use WD40!

I was jokingly mentioning WD40, but given that my key-not-responding issues keep on coming back I wonder why not?
After all, fixing connectivity problems is one of the main use cases of WD40, isn’t it?
I would obviously not spray the full keyboard, but a bit of WD40 on a paper napkin used to clean the legs of the switch may address this issue for good?
If the issue is not resolved by reseating the switches, it may be that the sockets themselves have come loose. If this is the case, disassembly of the keyboard will be necessary in order to find and fix the problem, which leaves the realm of standard user maintenance. I’m not a UGL employee, so do not take this as a recommendation from them!
If you feel comfortable disassembling the keyboard and inspecting the sockets, you can do that. If the sockets have come loose, they will have to be resoldered. There are guides on the site on how to disassemble the keyboard, but I understand if you are not comfortable going to those lengths, at least without the guidance of someone from UGL, or at the very least someone who has an actual UHK80 themselves, so this is where you may want to wait for input from someone else.
Unless of course you are like me and just throw caution to the winds, tear it apart and resolder everything.

Normal WD-40 leaves an oil film. It’s designed to lubricate and prevent oxidation, leaving a residue, it’s not meant as contact cleaner. A product that’s meant as a contact cleaner would be more appropriate.
I’ve had issues with a few keys failing over time. I started with swapping around switches and using contact cleaner, but in the end the issues were always that the keyswitch sockets had their solder crack off the pads on one side.
I can’t advocate for doing it yourself without getting in touch with support, but for me it was a lot easier to just disassemble, touch a soldering iron to the affected pads, and re-assemble than it would be to send it in for repair (and be without my keyboard for a couple weeks).
