The Keyboard Cable STAYS attached to the Keyboard.
It disconnects FROM the motherboard's connector.
The Keyboard Cable has NO connector on the end. It is a FFC.
Flat Flex Cable.
One example of a Flat Flex Cable,
http://en.wikipedia.org/wiki/File:Flat-Flex-Cable.jpg
The flat metal terminal bars MUST be aligned back in the SAME position, as they were originally.
For this reason you may wish to take a Sharpee marker, and make a mark on one side of the cable.
Then make a matching mark on the same side of the motherboard connector, BEFORE you remove the cable.
The motherboard connector is a type of ZIF connector.
Zero Insertion Force.
It is composed of two pieces, but does NOT come completely apart!
The bottom part is larger, rectangular shaped, and is stationary to the motherboard.
It is the BODY.
The upper part is smaller, rectangular shaped, and is movable.
It is the Locking Bar.
ACCORDING to the video the Locking Bar is the Slide/Wedge type.
DO NOT use a metal tool as shown. One slip, and you can damage the motherboard! Geez!
Use your Fingernails, or Thumbnails.
The Locking Bar slides up. Up towards the LCD screen, or away from the Body.
It ONLY moves about 2mm. That is a little larger than 1/16th of an Inch.
IF, the Locking Bar is broken, or the Body, you are looking at
-> MOTHERBOARD REPLACEMENT!!
Hence why I am being so detailed.
More detail on unlocking this type of motherboard ZIF connector,

There is another style of Locking Bar used, however.
The Locking Bar flips up to a 90 degree position, or also can be stated as Straight Up.
Just to make sure I'm going to include info for it too;
