Repair a model M keyboard

[MassMan]

My desktop system is quite old as I had bought it around 3 years back, but since then it has not come up with any major issues except for a few minor issues , but once there was an issue with my USB attached it suddenly had stopped working , and then after a while it started to function once again, but since then it stops working in between and works in an odd manner so now I am looking to replace it as it with a Model M keyboard , but in case if it goes faulty have anyone has got any idea how I can repair it.

Modfying a Keys and Springs

• Remove the keycaps using your fingers. There is no necessitate to snoop them off with anything. Just draw up on a keycap to take out it.
  
• Make use of a flat-head screwdriver to remove the internal key. Snoop up on the internal key quietly. Set the inside key aside.
• Take out the buckling spring from the internal -key post. The spring should now slide up off the post. Wipe the segment around the post with a cotton scrub and alcohol. Reinstate the buckling spring, inside key or key cap as required.

I can also tell you how you can actually replace the Keyboard Cable

• Unplug the telephone-type jack from the keyboard.
  
• Make use of a cotton swab and alcohol to clean the plug region of the keyboard.
• Plug the new cable to the keyboard and computer.
