These instructions will help you to remove and replace keyboards on various laptops. I will not be able to cover all models but you will get the idea. Steps for removing and replacing the keyboard are similar for most laptops.
Sony laptopInsert a small flathead screwdriver under the keyboard bezel and carefully lift it up. Continue releasing plastic latches and removing the keyboard bezel.
Be careful, on some models the bezel might be connected to the motherboard. If you accidentally pulled the cable, connect it back. It is not necessary to disconnect the keyboard bezel from the motherboard in order to remove and replace the keyboard, just put it aside so you can access the keyboard screws. Remove three (or more) screws from the top of the keyboard. Carefully lift up the keyboard from the laptop case. The keyboard connects to the motherboard via a flat ribbon cable. Before you pull the cable from the connector, you’ll have to unlock the connector.
Carefully move the connector lock 2-3 millimeters up and after that pull the keyboard cable. To install the keyboard, follow the above mentioned steps in the reverse order.

The keyboard bezel removal procedure is similar to the above mentioned Sony Vaio laptop. Lift it up with a small screwdriver and remove using fingers. On most Toshiba laptops the keyboard bezel doesn’t have any circuit board underneath, it is just a piece of plastic and you do not have to worry about cables.
After the bezel is removed you get an access to the keyboard screws. Remove two (or more) screws. Release the plastic latch pointed with the red arrow and lift up the keyboard. Carefully put the keyboard aside so you can access the connector underneath the keyboard. Do not forget that the keyboard is still connected to the motherboard.
Before you remove the keyboard, you’ll have to open the connector and release the flat ribbon cable.
