Nokia 3300B Keyboard Replacement.

Flip the Nokia 3300B over with the back-side facing towards you.

Gently press the button on the back of the battery cover to release the cover and slide up.

Lift the battery out of the back of the phone.

Gently push the blue tabs on the top of the phone out of their slots.

With the phone facing up, pop the blue faceplate off by using your fingernail (or some tweezers) and working your way around the phone.

Note: If the blue cover does not detach easily use your finger nails to try and split it open, as seen in the picture.

With the screen still facing you, lift and remove the blue faceplate.

Grab the sides of the keypad and lift each side up vertically, until the keypad is completely removed.
