This just happened to me and I tried the following methods:
* Compressed air blow on keys at an angle (didnt help)
* Pressed many keys with a slight pumping action (didnt help)
* Opened the back-panel, pressed the connection cables
Sometimes this would work but then every morning the same issue would occur.
So then I tried Apple Diagnostics by pressing “D” during start-up and weirdly enough my keyboard and mouse were working here, so that rules out a failing/loose cable.

The diagnostics went through and stopped at one point complaining about the power being at 45W but requires 75W to proceed with full diagnostics. So I connected my charger and continued with diagnostics, where everything checked out fine.

I then restarted normally and my trackpad and keyboard were working again :o

At this point I am not sure if my battery is failing but it seems if enough power is not coming on the lines then the keyboard and trackpad are simply disabled.

Then I turned it over and as usual, wanted to clean the surface to make it all shiny.

So I got a cloth and cleaned it. Then without any expectation, I turned it upright again, started the system and wtf!? …the keyboard and mouse came back up![br]

Looks like the cable just got loose due to gravity or some sudden lowering action, and my action of flipping the laptop over, wiping it with a cloth, basically exerting a slight force might have got the cable connection back in place.

Hopefully this is your case too. If not then don’t worry, just open the back panel, locate the cable, remove it and reinsert it.[br]

If not then replace the cable but mostly don’t get hyper :)
