Paralized keyboard hard to press keys

num lock or function lock is on Function is FN button some times in blue or your shift key is stuck down.

I’m happy to help further over the phone at https://www.6ya.com/expert/jason_66344e9ad974c715

If the KB is plugged in properly, Its time for a new one

If this is hardware problem, it'd be hard to repair. I don't mean it's not repairable, but what i mean is i don't recommend since repairing a keyboard and purchasing a new item will cost you more or less the same.
Well try this, Press Fn + Numlock (simultaneously on both the keys) on the keyboard and check if it helps or not [press once and then type the malfunction keys, if not press twice or thrice]. Most keyboard with Fn key's functions can be deactivated or activated with this key combination.
Good luck.

Thanks for using FixYa.

Time to replace the keyboard. You can get keyboards to fit your needs at most office supply stores at resonable prices.

Well there isnt a reset button its just that someone has pressed too hard on the keys or you can just buy a new keybord

Have you or someone else spilled something on the keyboard?
does the keys feel sticky or do they have problem retracting after its pressed?
Anything stuck underneath?

Use a can of compressed air to loosen dirt. Then turn kboard over and litely tap on back. You will be amazed at what falls out of the keyboard.

Is it a flat key or a normal keyboard type key?

If its a flat key make sure the things underneath the key are flat against the key and put it back on its spot and just press down on it until it clicks. You may need to press hard but please don't press too hard or you might do some damage.

try to clean the keypads and if it doesn't work you have to replace with a new one

Usually, this issue is caused by pressing F12 multiple times to access the 1 time boot menu.  This can cause the keyboard buffer to fill up and the keyboard will not respond.  Resolution:  Press F12 ONLY one time at boot.
If this is not the issue, then the other main cause is having an INTERNET keyboard that has alternate Function Key functions (These will be listed on the front edge of the Function keys and there will be an extra key called an F-Lock) This type of keyboard has the ALTERNATE function of the F-Keys enabled by default, you need to press the F-Lock key to enable the normal F-Key function.
