I use an external wired keyboard with my laptop which is connected to 2 external monitors. I recently went to lock my computer. Then I typed in my windows pin/password wrong multiple times. I had no idea how this happened. Now because of that, I had to restart my laptop. I could click on restart laptop and then restarted it.





After this, I am on my bitlocker pin page. It showed incorrect bitlocker pin and I was confused why. Then I decided to type my bitlocker pin on the laptop keyboard and it worked. Then when it went to the windows log in screen where you have to enter your windows pin/password, I notice it didn't work with the keyboard. Then when typing it on laptop keyboard it worked. I then noticed several keys did not work. It is the spacebar, n and b keys and also some of the arrow keys. The up arrow key worked for some reason. I then pressed it many times and it didn't work. Then a bit later, it worked. Are these buttons stuck or something? Now my wired keyboard... is very old and dirty. There is literally dirt and trash inside the keys in the keyboard. The thing is I find this keyboard very comfortable so that is why I still use it. It is from an old dell xps 8100 desktop from over a decade ago and this keyboard is comfortable.





Now at the moment, the keys do work. But if it doesn't work again, is this 100% the external keyboard if my laptop keys work without any issue? Is it possible because I entered my windows password wrong many times, this occurred? However, I think that isn't the case since when trying to enter my windows pin/password when computer is locked, those keys already didn't work? The pin/password does contain either the b or n letter etc. This is certainly not a driver issue then again and it has to be the external keyboard? Is there a way to clean it or remove all the dirt and trash from it? I did wipe it with alcohol and tissue but you can't get into the dirty inside. It is literally like trash and dirty inside the keyboard.

So as of now, those buttons sometimes doesn't work. I have lot of dirt, inside the keyboard but it has been like that for a long time though. So is this a stuck key or something else?


Dell keyboard from old dell xps 8100 desktop from back then.


Dell SK 8165 is the keyboard.


There is everything you can imagine inside the keys.



The thing is i don't want to risk damaging the keyboard as i cannot buy another english keyboard here. Also want keyboard like this.



As of now, the letters b, n, diagonal, arrow keys do not work.


So me posting a picture of my keyboard you can give me the best advice here? Thing is if i was in us now, i can buy another one but can't here so sort of don't want to risk damaging the other keys.



Any point in this below? Or is this the specific keys?



Run DISM and SFC if have not done so.



Check in Device Manager as to what Driver is being used for it. If it is a windows Driver from 2006 then that is possible issue as if taking Drivers from Windows Update it has replaced

it.

A common cure for keyboard and mice issues is to delete the driver in Device Manager and to reboot. It will be recreated at start up

You can't damage a keyboard.
There are plenty of youtube videos on how to clean any type of keyboards. For generic ones, all you need is a screw driver.

Take a good, clear photo of the keyboard as, when you open it up, all the keys will probably fall out in a chaotic pile.

It's fairly evident that you have a mechanical problem with the wired keyboard. Just bite the bullet and open it up for a clean.

You can use an artist's paint brush and an air-duster aerosol. Be gentle. Good luck.

Alternatively, there are 41 on eBay, just make sure the language layout is correct.

Search eBay.com for 385375546393

As you are outside the US you can probably find one on the local eBay, I was looking at your timezone!

Yes, it is a USB keyboard, identical to what you have. Where are you?

There are 28 new keyboards with English layout currently on eBay, brand new.

Before you try taking it apart, try canned air - that has often done the trick on it's own for me - it's very powerful. Also just the end of a paperclip around the edges of some keys in case there's a bit of grit that can just be easily scraped out.

Best way to check if it's mechanical or software is try using a different keyboard - if you can borrow one. It might even be a dodgy usb connection or something. Also have you tried disabling sticky keys and toggle keys in settings?

    Originally installed with a 500gb H10 Optane ssd
I've got the same problem with the same keys suddenly not working however it is a brand new keyboard that ive just had installed, its only two weeks old and absolutely nothing has been spilled on it. ive taken it apart and theres no signs of physical damage whatsoever. ive gone through every forum i could find, seems to have happened to loads of dell, asus and lenovo laptops over the past three years and most threads end with no working solution. i have done the removal of keyboard in device manager, have also updated all drivers, have ticked sticky keys and filter keys on and off, have tried a random suggestion of holding space enter and backspace for five to ten seconds which oddly did revive the buttons for a few minutes. have reset windows and tried to install linux but the problem exists even in the bios. im stumped.

It might be a damaged ribbon or connector onto the motherboard. But if you paid someone to install it why did you not get them to fix it? Is the keyboard a replacement for a faulty keyboard?
