In the following guide I explain how to remove and replace the keyboard in a Dell Inspiron 1545 laptop. You can use this guide if the keyboard stopped working properly or you accidentally spilled something on the keyboard and damaged it.
Most likely this guide will work for some other Dell models. If it works for you, please mention the laptop model number in comments after the post.
Turn off the laptop, unplug the AC adapter and remove the battery.
In the battery compartment you’ll find two screws securing the center control cover. Remove both screws.
Insert a flat head screwdriver between the control cover and laptop base and carefully lift up the cover.
Continue removing the center control cover with your fingers.
Remove the center control cover.
Remove two screws securing the keyboard.
Lift up the top side of the keyboard as it shown on the picture below.
Be careful, the keyboard is attached to the motherboard with a flat ribbon cable.
Remove the keyboard so you can access the keyboard cable underneath.
The keyboard cable can be removed from the connector only after the connector is unlocked.
WARNING! If you damage the keyboard connector, you’ll have to replace the whole motherboard. The keyboard connector is permanently attached to the motherboard.
On the picture below the keyboard connector is shown in the locked position.
Carefully flip the brown part of the connector up, so it opens up at a 90 degree angle.
On the picture below the keyboard connector is shown in the unlocked position.
Now you can pull the keyboard cable from the connector and remove the keyboard from the laptop.
Replace the failed/damaged keyboard with a new compatible keyboard.
You can search for a new keyboard by the Dell part number printed on the sticker. In my case the part number is 0P446J.
